FACILITATING RESOURCE AND MATERIAL STORAGE
STIMULATING HIGH-VALUE REUSE
STIMULATING MATERIAL PASSPORTS
Matching demand and supply of building materials and resources requires temporary storage. Two possible roles on which the municipality can focus are: (1) allocating locations for the physical storage of these materials, and (2) playing a facilitating role in drawing up the conditions that the materials have to meet in order to qualify for storage and reuse.
High-value reuse of building materials can be encouraged by the government in two ways in the current early stage of development: (1) contributing to the development of procurement guidelines and building codes with specific requirements for high-value reuse, and (2) being a launching customer for recycled and reused building materials.
A materials passport for buildings captures information on materials and processes used, and the possibilities for material reuse. The municipality can recommend or make mandatory a basic version of material passports for new construction projects and implement material passports for its own properties.
A follow-up analysis is needed to study changes in the construction material flows in the city both for large demolition projects and new construction. Complemented by available knowledge on zoning plans and a structural vision, such analysis can identify locations for the (temporary) storage of raw materials.
The municipality could develop criteria for building regulations, ensure compliance calls for an increase in commitment, and co-invest in new processing technologies through the AKEF or a Fund for Circular Development. The municipality’s precondition could be that the activities are based in Amsterdam and benefit the city.
Involvement of the municipality and city officials is required to determine how the materials passport for buildings can be embedded in policy. Input and information on facilities from the land registry are also required for the passport.

VIRTUAL RESOURCE PLATFORM
CIRCULAR FREE ZONE BIO-REFINERY
The municipality can further develop and make publicly accessible digital (commercial) platforms for organic waste. Such a platform would offer a transparent overview of the supply, the demand and the use of organic residual streams in Amsterdam (and beyond). In addition, it can address the uncertainty in the market by improving the balance of supply and demand.
The municipality can initiate circular free zones. This could take away certain (legislative) barriers that currently hinder innovation, such as the ban on the use of digestate on agricultural land. This is currently blocking an important and essential part of the business case for anaerobic digestion as the current market value of digestate is low.
The municipality can introduce criteria in its purchasing policy to stimulate locally produced grass, wood (as in street furniture) and food (catering). The large buying power of the municipality itself can create an important and constant demand that allows local parties to further develop and professionalise.
The investment in setting up a platform consists largely of the development of the ITinfrastructure and the time it takes for the conceptual development of a platform. The municipality can be the initiator; however, there are many market participants, including large IT parties, which develop such platforms.
The designation of circular free zones can be an effective way to neutralise the barriers described in the local barrier overview. It is a measure that requires investment in establishing proper supervision and enforcement. The measures to be taken fall completely within the perspective of the Municipality Act.
The effects of these measures may soon be visible since there is a direct market demand for local products. This is expected to be quickly absorbed by the market.

TITLE 1. INTRODUCTION: MUNICIPALITY OF AMSTERDAM AS A PIONEER
The urgency of the transition to a circular economy Our linear way of producing and consuming is under pressure. The world’s population will grow to nine billion people by 2050, and, as the city of Amsterdam urbanises and grows by 10 thousand inhabitants per year, the demand on resources rises. This demand, combined with the finite supply of resources, will lead to scarcity and strong price fluctuations. More and more companies are, therefore, opting for the transition to a circular economy, which offers opportunities for innovation and export of new production techniques and business models, while reducing dependency on imports. For citizens, a more circular city will improve their quality of life, create new jobs and form new business models for entrepreneurs. Amsterdam wants to be the front-runner in circularity, and the Amsterdam region is in a good starting position for transitioning to a circular economy. The region has many entrepreneurial and innovative businesses, citizens, start-ups, organisations and knowledge institutions that are already working within the framework of a circular economy. The city of Amsterdam works according to the following seven principles of the circular economy: 1. All materials enter into an infinite technical or biological cycle. 2. All energy comes from renewable sources. 3. Resources are used to generate (financial or other) value. 4. Modular and flexible design of products and production chains increase adaptability of systems. 5. New business models for production, distribution and consumption enable the shift from possession of goods to (use of) services. 6. Logistics systems shift to a more regionoriented service with reverse-logistics capabilities.
7. Human activities positively contribute to ecosystems, ecosystem services and the reconstruction of “natural capital”. Circular economy as a pillar for Amsterdam The municipality of Amsterdam has committed to the circular economy as an important pillar of its sustainability policy, as apparent in its sustainability agenda (Amsterdam, 2014a), adopted on 11 March 2015. Within the existing policy, there is already space to accelerate the transition, through the development of circular free zones, for example. This is a good starting position, as confirmed in the national Green Deal, ‘The Netherlands as circular hotspot’. Lately, the region has experimented with pilot programmes in the transition to a circular economy; however, the municipality wants to commit to a real transition in the coming period, and the efficient recovery of natural resources and materials, within the construction sector is an important area of focus. As the municipality would also like to stimulate economic activity, research and innovation, it is important to get a picture of the entire system, which is why Circle Economy, TNO and Fabric were hired to do a Circle Scan for the city. The changing role of Governments Circular business models are increasingly seen as promising by businesses (Accenture, 2014). As a result, the transition to a circular economy is mainly driven by companies at the moment. These frontrunners still experience many barriers (regulation, for example), which slow down the speed of the transition. Governments play a crucial role in facilitating and guiding the transition to a circular economy (EMF, 2015a). Especially at the city and regional levels, the circular economy is taking shape and groups of citizens and businesses are starting all kinds of circular initiatives (RLI,
2015). These developments show that a great deal of interest and commitment currently exists to capitalise on the opportunities offered by the circular economy. To scale up these initiatives support from the government is essential. The government of the future does not direct, but brings parties together. To play that role, the government ought to remove barriers resulting from existing policy and actively encourage and challenge the market. One can think of, for example, the development of inspiring goals for a circular city, such as adjusting the private purchase and tender conditions, stimulating innovative research and start-ups that contribute to circular solutions, and implementing financial incentives. This last point, for example, can be fulfilled by differentiating tax rates and investing in good infrastructure to increase exchange of resources. A close cooperation between the government and the market offers a great opportunity to accelerate the transition to a circular economy. Amsterdam Circle Scan: from vision to action This document describes the results of the ‘Amsterdam Circle Scan’ and analyses the opportunities and challenges of creating a circular city. The results contribute to the further development of the municipal ambitions and agenda on the theme of a circular economy. The roadmap outlines steps towards stimulating the circular economy in the city. To create a circular economy, we must first understand what is not circular in our current economy. This document provides insight into the commodity flows in the city and metropolitan region. It shows where the processing of resources adds value to the local economy and how they can be reused in a smart way while highlighting where resources are being wasted. The report focuses on two value chains with a significant impact, their contribution to the regional economy and their potential to be
more circular - Construction and Organic Residual Streams. For both value chains, we explored what a circular future may look like. To make the vision more concrete, four strategies were developed and translated into a specific roadmap for the city and region with concrete action points. The report concludes with recommendations and next steps. A key recommendation and follow-up step involves making circularity more measurable in order to monitor progress. The ‘circular indicators framework’ applied in this study offers a good starting point. Jump start: build on momentum The ambition to be a circular hotspot is widely supported in Amsterdam. Not only is the municipality progressive, but citizens and businesses are equally enthusiastic and energetic about the transition to a circular economy. The city is buzzing with circular initiatives, and this was once again made clear during conversations held in the region to gather input for the future visions and action points in this document. With the action points presented in this report, we want to contribute to and build on the growing momentum for the circular economy in this region. In the action agenda, we connected and built on, as much as possible, the many initiatives already underway. Internationally, Amsterdam is a pioneer and is being followed by other cities in Europe and beyond.
MAPPING OF MATERIAL FLOWS AND ADDED VALUE To get a better picture of how circular Amsterdam currently is, the main material and energy flows as well as employment in the economic sectors in the region were analysed. The analysis employed data from (regional and national) statistics and sources, and was supplemented by interviews. It provides insights into material flows in and around the city. Simultaneously, activities and places in the region were assessed for their ecological impact. In addition, the analysis provides insights on where and how value can be created in the region and where there are opportunities for job growth and economic development.
THE CITY CIRCLE SCAN METHOD The City Circle Scan is a method that gives direction to cities through the development of a roadmap and action agenda for the practical implementation of the circular economy in their city and region. The method consists of four phases.
EVALUATION AND SELECTION OF CHAINS In phase 2, a comprehensive analysis was conducted of the value chains that connect multiple sectors within Amsterdam. The results of phase 1 were the starting point of this analysis. Based on macro-economic statistics, we established in which chains the greatest circular impact can be achieved. The result is a list of chains that have been prioritised on the basis of the following indicators: ecological impact, economic importance, value preservation and transition potential. These indicators were also used in the Dutch national government program, â€˜Nederland Circulair!â€™.
VISIONING Then, in phase 3, we developed a future vision, exploring how the two chains can function in an ideal circular future. This future vision gives a view on how the chains (and their interactions with other chains) can be set up differently. For each of the two chains, we formulated four strategies for a circular economy. The future vision was tested in feedback sessions and in interviews with various experts and stakeholders in Amsterdam. The feedback was used to further refine the vision for the future.
PROJECT SELECTION AND FORMULATION OF ACTION POINTS In phase 4, an action agenda with a planning and implementation strategy for starting relevant circular projects was drawn up. All are projects in which governments, research institutes, companies, entrepreneurs and citizens work together to make the two chains circular. Time paths for the actions and policy interventions were formulated, indicating which stakeholders are essential for a successful transition. The actions have also been assessed on four main effects: (1) value creation, (2) CO2-reduction, (3) material savingsstraatmeubilair and (4) job growth.

2. VISION OF A CIRCULAR CONSTRUCTION CHAIN IN AMSTERDAM To get a picture of how the construction chain in Amsterdam can make better, higher-value and longer lasting use of material flows, we explored a potential future of the construction industry in Amsterdam. This vision of the future was partly based on interviews with experts and stakeholders. Their feedback was used to further refine the vision of the future. The starting point of this exploration was to retain the highest possible value in the construction chain by means of circular solutions. Therefore, this chapter describes four strategies that can be followed. These strategies are then placed in the context of the region (by linking with local initiatives and a selection of innovative market parties). Furthermore, a link is made with trading opportunities for the municipality, areas where the market is active and ways that the government can facilitate this. The roadmap describes concrete action points for the municipality, links this to timelines, and highlights which parties can play a role in the implementation. In addition, the impacts of implementing the strategies are calculated for: (1) value creation, (2) CO2-reduction, (3) material savings and (4) job growth.

Modular and flexible design One of the aspects of smart design is a modular and flexible approach, whereby buildings can be updated to new users and other applications without sacrificing the current safety guidelines (Schoenborn, 2012). These designs lead to real estate that is more functional and more durable, thus, offering a better revenue model during the utilisation period. Examples of integral modular designs are Solid in Amsterdam by housing association Het Oostent, TempoHousing student accommodation by Keetwonen in Amsterdam and Park 20 | 20 by Delta Development Group in Hoofddorp. Flexibly designed houses are often more attractive to users because they can adapt to changing lifestyles. For example, Hubbell in Amsterdam builds modular spaces for individuals. Companies also prefer flexible offices because they do not need to move as their business situation changes. Start-ups and other fast-growing companies in particular can benefit from such offices. Rent or purchase of flexible office space can even result in cost savings (Cushman & Wakefield, 2013). 3D-printing New technologies, such as 3D
printing, can play a pioneering role in reducing cost and material use (EMF, 2015b). Such technologies lead to less waste and offer the possibility of new (e.g. bio-based) materials. The Amsterdam firm of architects, SO Architects, has, in collaboration with Hager and Henkel, started the project “3D Print Canal House” to investigate the possibilities of 3D printing for the construction industry. The research project looks at different building materials, such as recycled construction materials and stone waste (SO, 2015). Bio-based materials New, sustainable building materials with a biological origin can contribute to designing smarter buildings. More than 3 million tonnes of biomass and organic residual streams are released from agricultural activities in the Amsterdam metropolitan area, from which significant amounts of bio-composite materials can be produced. This would, at least, be sufficient to supply the materials needed for the planned housing expansion of 70 thousand homes (CBS, 2014). An interesting example of sustainable building materials is the work of Waternet, who, together with stakeholders such as NPSP and Cityblob, develop composite components. The municipality of Almere has already commenced projects involving bio-waste, which is used to generate bio-composite for the building sector. The 60 thousand m2 of buildings planned for the 2022 Floriade can be built as circularly as possible through the use of biomaterials. Another interesting example is the trajectory of Waternet in which waste streams such as water plants are converted into (building) products. Experimental construction areas Laws and regulations can be adjusted to make it possible to develop bio-based, modular buildings with flexible applications (Acceleratio, 2015). By modifying the building codes, developers get more room to experiment and more freedom to

MODULE A SMART DESIGN
Mobile 3Dprint facility
Smart design of buildings is important in the transition to a regional construction circular chain (EMF, 2015a). Inhabitants move more frequently, so work areas should be regularly adapted to meet changing work patterns such as mobile working and flexible working hours. In addition, it has been found that companies tend to move to another building rather than renovating the current one. These factors lead to an increasing demand for flexible and customisable areas that meet the changing demands of tenants and owners. To illustrate the concept, we will focus on four categories of smart design, namely, modular and flexible design, 3D printing, bio-based materials and experimental construction areas.

MARKETPLACE AND RESOURCE BANK Logistics for collection An online marketplace alone does not necessarily make the collection and transportation of construction- and demolition waste easier or cheaper as the material is very diverse and voluminous. Therefore, there is a need for an advanced collection system and for intelligent logistics, which would make the exchange of building materials easier. Because many developing locations are located near waterways, the port of Amsterdam can be a central point in that logistical system. Shipping companies could play an important role in transport. Many logistics companies such as DHL and PostNL have considered offering reverse logistics for a wide range of material flows. In reverse logistics, an

empty truck would be used for retrieving waste after it has delivered its products.
Online Marketplace Via an online marketplace, supply and demand of building materials for local construction projects can be aligned (by means of GIS data) (Zhu, 2014). Besides information on the building, an information management system, building passports, and information on the quality and quantity of materials used in a specific building can be documented and made accessible. This provides opportunities for trading and the exchange of building materials between parties, and encourages reuse and high-value recycling. Enviromate has developed an online marketplace where construction companies can exchange and trade waste materials of construction projects in the United Kingdom. Such a system can also be used in Amsterdam. For new buildings in Park 20|20, material passports are already being developed. These can also be applied for buildings in the rest of the region.
Commodity bank Currently, there are challenges in the temporary storage of construction waste at companies, mainly because this requires space and, thus, investment. A solution could be to arrange a centrally located physical storage for materials (commodity bank) - materials that are then traded in the online commodity market place. Vacant plots around Amsterdam, such as in the port and in Westpoort, Zaanstad and Almere, are ideal locations for the temporary storage of construction waste before it is traded through the online marketplace. Designers and architects are invited to view a catalogue with materials to see if they can come up with new applications for these materials. Several companies, such as Brink Industrial, Repurpose, Turntoo and Icova, are working on their own resources banks.
MODULE A SMART DESIGN
Each building can be seen as a material bank full of valuable materials. A building could be seen as a modern take on traditional mines (United Nations University, 2014). However, after the dismantling, separation and recycling of building materials, a gap between the demand and supply of these resources remains. Demolition and decommissioning projects provide opportunities for processing and direct reuse of recovered materials in nearby construction projects. However, it is often unclear which materials are present in existing or decommissioned buildings and of what quality they are. High-value reuse is, therefore, a major challenge. There is a need for a comprehensive online marketplace and

Many of the ways to achieve a circular economy may already be profitable but often barriers present themselves when up-scaling a solution. Policy can play an important role in removing these barriers. We distinguish four types of barriers:
secondary resource flows. The lack of externality
Laws and regulations Existing policy often leads to unforeseen consequences of changing market conditions. An example of this is the Environmental Management Act (art. 1.1), which describes what is classified by law as waste and what is not (Government, 2015).
Technology Technological development has two important challenges: the up-scaling of a small pilot to commercial scale, and the interdependency and complexity of technologies that require simultaneous development.
Financing is difficult and it can be more expensive to implement new systems or sustainable materials. This approach requires a shift from cost-oriented thinking to a life-cycle approach (Buildings, 2009)
These barriers have important implications for the extent to which some of the strategies can be implemented successfully, especially in the
Green building materials are currently seen as a niche product. This is because of a lack of economies of scale: there is not yet enough demand for the technologies, which is necessary in order to be able to reduce the cost of production (Remodelling, 2008).
Culture The circular economy requires close cooperation between sectors and chains. A lack of inter-sector networks and a conservative culture can be obstacles to quickly forming successful cooperations. Vested interests in sectors can add to this barrier. Market The existence of â€˜split incentivesâ€™ is a barrier; the investments must be done by one stakeholder in the chain while the income is earned by another. Another market-related barrier is knowledge asymmetry, for example, knowledge with regards to the availability and quality of
pricing, including that of CO2, can also have a significant effect on the market. The last barrier that we want to mention in this category is the limited access to financing for circular initiatives.
short term. In some instances, governments can overcome these barriers or the market may break down barriers; but, in many cases, the solution requires cooperation, experimentation and iteration. Below, an impact assessment per barrier is made for each of the four circular strategies. The assessment of the severity of the barrier comes from insights obtained from the interviews and is further based on estimates of the research team. For the top 3 proposed actions, the roadmap will address options to overcome these barriers.
There are limited opportunities in making 3D-printed buildings or components comply with current building regulations. The Building Act contains no guidelines enforcing cooperation between developers and the city, its current residents and future residents in developing a flexible design plan (National Government, 2011). Modular homes are, in most cases, only acceptable for social housing. These are difficult to finance because the income of the tenant is modest compared to that of tenants of more expensive types of housing (Tempohousing, 2015).
The speed with which technological innovation in the construction sector takes place - especially the development and application of new materials - is high (Sinopoli, 2010). 3D printing is such a recent innovation: its use is still very limited in the construction sector. The challenge for upscaling is mainly to achieve economies of scale.
The building/construction industry is a conservative sector that has not embraced new methods and smart design for buildings have not yet (Barkkume, 2008). Costs for dismantling and collection can be 2.5 to 3 times higher than demolition costs. The costs for dismantling and collection form a barrier when the added value of the recovered building materials is not yet fully understood (Chini, 2002). Fast and economical cost effective techniques are essential to accept dismantling and collection as the default application (Big House, 2014). There is a lack of information, experience and resources to design for both decommissioning and collection. Many buildings are designed for a lifespan of several decades. There is too little account of what happens with the building after this time. High taxation on labour and low tax on resources discourages using recycled resources. Besides, labour-intensive processing methods are relatively expensive (national Government, 2011).
LAWS & REGULATION
The Building Act contains no reuse and high-value recycling of building materials over downcycling or burning (National Government, 2011). Recovery of valuable materials from buildings is often not economically viable because conventional building methods often mix materials making recovery difficult or impossible. (Buildings, 2009).
Building constructions often have unique dimensions and are build for specific purposes, making it difficult to use them for other purposes (Phys, 2015).
DISMANTLING & SEPARATION HIGH-VALUE REUSE
In some cases, reconstruction and reuse of a building is more expensive and the impact on nature is bigger than demolishing it and building anew (Tempohousing, 2015).
MARKETPLACE & RESOURCE BANK
There is no transparency and alignment in the market on the supply and demand of (regained) building materials, resulting in high transaction costs. It is essential that all information in the field of building production and the assembly process remains available (National Government, 2011). There is a lack of market for reclaimed building materials (Remodeling, 2008).
This table indicates how high the barrier to a circular economy is for each of the strategies. (Source: Insights from interviews, literature ((Acceleratio, 2015; EMF, 2015) and assessment of the research team.)

STIMULATING HIGH-VALUE REUSE BY BEING A LAUNCHING CUSTOMER AND CONTRIBUTING TO THE DEVELOPMENT OF PROCUREMENT GUIDELINES.
BOOSTING MATERIAL PASSPORTS AND CONTRIBUTING TO THE DEVELOPMENT OF GUIDELINES.
Matching demand to the supply of building materials and resources requires temporary storage, especially since the availability of large volumes of materials often does not synchronise with demand. A possible role for the government could be twofold. On the one hand, there is a need for physical storage facilities, for which the municipality can play a role in allocating locations. Given the expected volumes, locations near waterways are ideal for replacing road transport with water transport. On the other hand, the government can play a facilitating role in drawing up conditions that materials will need to meet in order to qualify for storage and reuse.
In the early stages of development, high-value reuse of building materials can be encouraged by the government in two ways. The government can contribute to the development of procurement guidelines and building codes in which specific requirements have been formulated aimed at high-value reuse. Also, the government can play a role as launching customer for the use of recycled materials. Every year, 1.5 billion is tendered by the municipality for roads, waterways and construction. In addition to contributing to physical locations for the storage of resources, an online platform for the trading of building materials to match supply and demand is under development.
A materials passport for buildings captures information on materials used, processes and possibilities for reuse. The Government can make sure a (minimal version of a) material passport is recommended or made mandatory for new construction projects. Also, the municipality could implement material passports for its own property portfolio. Besides this, the municipality can contribute to the development of guidelines for passports. An example of this could be exploring how the use of passports can be made mandatory in real estate development and the issue of plots of land.
Initiatives to establish physical resources banks have sprouted up throughout the country. Individual companies are now starting to set up their own resources banks in collaboration with up- and downstream companies. Amsterdam can facilitate innovation by creating a material repository that is backed by a wide range of stakeholders. This ambition’s logistical challenges align with the initiative to the give the Westas an important logistical role in the circular economy. (ALB, 2015)
The municipality’s material department plays an important role, and parties that innovate by reclaiming high-quality materials, such as Stonecycling, are also key players. Struyk, for example, uses end-of-life concrete pavement. The municipality can bring these like-minded parties together and encourage them to experiment in extending their technologies. Furthermore, this links to CO Green in Slotervaart, an ongoing project where 95% of high-quality material is reused locally after demolition. In addition, it is connected to Cirkel Stad Amsterdam where local projects in the field of circular construction, renovation and demolition are realised and, where possible, additional jobs are created (Cirkel Stad, 2015).
Some construction companies in The Netherlands are currently experimenting with material passports. In the vicinity of Amsterdam, Park 20/20, realised by Delta Development, Reggeborgh and VolkerWessels, is a great example. In addition, these principles are most likely implemented in the Buiksloterham area as well.
A follow-up analysis is needed to study changes in the construction material flows in the city, both for large demolition projects and new construction. Complemented by city planning expertise, this analysis forms the input required for assigning locations for the (temporary) storage of resources. The actual operation and organisation of these sites can be organised by both market participants and the municipality - or through public-private partnerships. Depending on the direction taken, the precise role of the municipality is to be determined.
Developing criteria for building regulations and ensuring compliance calls for an increase in commitment. The municipality could possibly co-invest in new processing technologies via the AKEF or a circular development fund. A possible condition for this contribution could be that the activities are based in the city of Amsterdam so that any employment gains are realised in the city.
Involvement from the municipality and city officials is required to determine how the materials passport for buildings can be embedded in policy. Services like those offered by the Kadaster are needed in registering passports. The introduction of the passport also requires investment into the expansion of registration systems.

Four indicators have been used in determining impact: (1) net added value in millions of euro, (2) net job growth in FTE, (3) material savings calculated by value retention in domestic material consumption and (4) reduction in CO2-emissions. The values for the four indicators are shown in the four circles. The bar chart shows the distribution of added value.
SCALABILITY MAP The scalability map shows locations where opportunities exist to apply the four circular construction strategies for the construction chain. The strategies are dismantling and separation, high-value reuse, smart design, and the creation of a marketplace and resource depots. The red areas indicate future real estate projects. Blue represents areas where circular strategies on existing buildings can be applied. The white circles represent locations currently not in use, which can be considered as possible locations for the storage of materials or for developing new circular building projects.
3. VISION OF HIGH-VALUE RECYCLING OF ORGANIC RESIDUAL STREAMS IN AMSTERDAM In order to achieve high-value recycling of organic residual streams in Amsterdam, we established a circular vision. The vision and roadmap were supplemented and refined based on conversations with experts and stakeholders. The starting point for the analysis was the realisation that there are many initiatives in the city and in the region that are focused on higher value processing of organic streams. At the same time, there is an opportunity to develop a strong cluster that focuses on further value retention and optimised cascading of organic residual streams in Amsterdam and the surrounding region. This chapter describes four strategies that are tailored to the region and link with local initiatives and innovative market parties. Furthermore, the chapter considers trading opportunities for the municipality, areas where the market is active and the role of the government is that of a facilitator. The roadmap describes concrete action points for the municipality to link to time lines, and highlights which parties can play a role in the implementation. The impacts of implementing the strategies are calculated for (1) value creation, (2) CO2-reduction, (3) material savings and (4) job growth.

BARRIERS Many of the ways to achieve a circular economy may already be profitable but, when up-scaling a solution, barriers often emerge. Policy can play an important role in removing these barriers. We distinguish four types of barriers: Laws and regulations Existing policy often leads to unforeseen consequences in changing market conditions. An example is the Environmental Management Act (art. 1.1), which describes what is legally classified as waste and what is not (Government, 2015). Culture The circular economy requires close cooperation between sectors and chains. A lack of inter-sector networks, a conservative culture and vested interests in sectors can be obstacles to the efficient formation of successful cooperation. Market The existence of â€˜split incentivesâ€™ is a barrier; the investments must be done by one stakeholder in the chain while the income is earned by another. Another market-related barrier is knowledge asymmetry, such as knowledge with regard to the availability of secondary resource flows and its quality. The lack of externality
pricing, including that of CO2, can also impact the market. The last barrier that we want to mention in this category is the limited access to financing for circular initiatives. Technology Technological development has two important challenges. Up-scaling a small pilot to a commercial scale is often challenging, and the interdependency and complexity of technologies that must be developed together can also be a barrier. These barriers have important implications for the extent to which some of the strategies can be implemented successfully - especially in the short term. In some cases, governments can overcome these barriers, and the market may break down barriers in others, but, in many cases, the solution requires cooperation, experimentation and iteration. For each of the four circular strategies, an impact assessment per barrier is made below. The assessment of the severity of the barrier comes from insights obtained from the interviews and is further based on estimates of the research team. For the top three actions, the roadmap will address options to overcome these barriers.
LAWS & REGULATIONS
The flow of organic residual streams is highly varied, both geographically and across time (impacted, among other things, by seasonal variations in green waste such as roadside grass), which forms an obstacle when trying to complete the business case. High-value bio-refinery technologies are in the early stages of development. For up-scaling and commercial viability, significant investment into additional research and development (R&D) is required. A lack of funding for this can make both the speed of and the chances for success uncertain. Market demand for end products of bio-refining is currently low due to factors such as ignorance of market players, a limited ability to realise significant supply and a lack of clear quality criteria. The production of high-quality protein by growing insects (larvae) on organic residual streams must comply with the current laws and regulations regarding slaughter of live animals, which raises practical and, thus, financial barriers. Policies that aim to increase the share of green gas into the natural gas network give too little consideration to the interests of importers and more to the interests of (traditional) network operators. Recovered nutrients, such as phosphates (by processing of struvite, for example) from waste water may, under current laws and regulations, not be applied as fertiliser on agricultural land and can, therefore, not be capitalised on, which makes the business case more difficult. A recently signed green deal provides an adjustment in the classification of waste under VANG and REACH (Sloover, 2014). According to current legislation, digestate from anaerobic digestion cannot be used as fertiliser on agricultural land (to replace artificial fertilisers), which complicates the profitability of digester plants. For waste substances, a waiver on the legislation is required per waste substance and per installation. This is an intensive and lengthy process that has been undertaken for struvite in Amsterdam. European regulations concerning the 'expiry date' and food hygiene create uncertainty for the high-value reuse of food. Various technological possibilities to enable greater source separation rates of organic residual streams are being examined. The technological complexity of these solutions (such as the link between technological installations in households and the necessary infrastructure) raises challenges that require both further technological development and the planning of underground installations and infrastructures. The above table is a summary of the most relevant and significant barriers that apply to this chain in achieving a transition towards a circular economy. This is based on research, literature, interviews and insights from the research team.)
CENTRAL BIO-REFINERY HUB WASTE SEPARATION AND RETURN LOGISTICS CASCADING ORGANIC FLOWS RECOVERING NUTRIENTS This table indicates how high the barrier to a circular economy is for each of the strategies. (Source: Insights from interviews, literature and assessment of the research team.)
ACTION POINTS CENTRAL BIO-REFINERY HUB 1. Expanding and designating new ‘free zones’ and ‘circular field labs’ In a number of industrial clusters, such as the harbour area, policies can be temporarily eased to support the development of bio-refining activities. Legislation that currently stands in the way of the development of biorefinery concepts includes the ban on the use of digestate, which is rich in nutrients (especially phosphate), on agricultural land. This is currently blocking an important and essential part of the business case for anaerobic digester plants because the current market value of digestate is low. This legislation also affects Waternet, which recovers phosphate from waste water (by the precipitation of struvite crystals through the addition of magnesium) but cannot currently sell the reclaimed nutrients nor apply them to agricultural land. A Green Deal, recently signed between the Dutch Ministry of Infrastructure and the Environment and the water boards, should, however, lead to changes in the classification of recovered substances under VANG and REACH (Sloover, 2014). 2. Further developing of a sustainability fund specified for the circular economy A circularity fund should be financed by public and private parties with the aim of financially supporting innovative projects before the market provides starting capital, private equity and bank financing. The circularity fund can build on the experiences of the ‘Amsterdam climate & energy fund’ (AKEF) Sustainability Fund, which provided financing and investments in the form of loans, guarantees and capital shares (AKEF, 2015). The fund should provide a solution to the financing of early stage (usually lab- or pilot scale) projects that want to upscale to a commercial level. 3. Establishing criteria for ‘new bio-based products’ Currently, the market is being hampered
by uncertainty around quality specifications for bio-based products. The lack of clear criteria is currently a problem for two projects involving the breeding of insects using organic waste with the aim to produce proteins that can be used as fodder in, for example, aquaculture. Growing insects now falls under the complex regulations of the Slaughter Act. The establishment of clear criteria can give clarity to this underdeveloped market.
2. Rebuilding waste hubs into centres for the circular economy Current waste hubs can be transformed into recycling activity hives similar to the municipal recycling platforms in Almere, where high-value recycling is applied locally (Municipality of Almere, 2015). This would increase the local level of circular activities. In addition, it would increase the knowledge of local residents by involving them in recycling and other circular activities.
4. Differentiating Amsterdam as an ‘(innovative) hub for bio-refinery’ A communication strategy is required to strongly distinguish Amsterdam from other port cities in the field of circular economy and bio-refining activities. The municipality can invite leading companies to establish and further develop their activities in Amsterdam. This can build on existing initiatives, such as Startup Amsterdam, with a focus on bio-refining, and be deployed as an innovation hub. The port of Amsterdam, together with the surrounding cities, can develop a stimulus package and match-making services to entice companies to locate in the region.
3. Equipping street containers and waste infrastructure with smart IT systems This optimises reverse logistics and the share of separated waste collection at source (Amsterdam Connecting Trade, 2014). This can lead to a decrease in the amount of transport needed. By connecting information about the composition of waste, the residual flows may be worth more. The system can be tested on ease of use and (financial) feasibility through small-scale pilots in cooperation with companies, suppliers and households.
WASTE SEPARATION AND RETURN LOGISTICS 1. Renovating underground waste containers The renovation of waste containers, in Amsterdam-West, for example, can lead to an improvement in the share of source separated waste. The suggestion is to equip existing and new containers with the ability to separate fruit and vegetable waste in addition to the current separation of paper and glass. A container replacement campaign is being rolled out in Amsterdam West over the next three years. This modernisation could act as an incentive for local SMEs and for metal- and installation companies in particular. New requirements for separate waste collection can also be included in procurement criteria for the municipal waste infrastructure.
4. Creating variable tax rates for different waste categories (in the so-called Diftar-system) In very densely populated residential areas of urban regions, it is more difficult to separate household waste. By taxing grey household waste more heavily through a differentiated tax system (Diftar) (Drift, 2014), source separation of domestic waste will be (financially) stimulated. CASCADING ORGANIC RESIDUAL STREAMS 1. Creating ‘breeding grounds’ to promote urban agriculture This increases local food production and biomass production. In addition, empty buildings can be used to produce food. Examples of and initiatives in urban agriculture are expanding rapidly. An example in Almere is ‘Agromere’, which aims to put a process in motion that should eventually lead to a new residential
area in which agriculture is fully integrated (Jansma, 2015). 2. Stimulating locally produced products, biomass and nutrition through purchasing policy Local production of biomass and food reduces the need for transport, benefitting the environment (PBL, 2014). One of the sources for wood is green areas of the city (City of Amsterdam, 2014a). To increase the production of biomass at the municipal green facilities, a more holistic approach to the management of municipal green and waste is required. Public green spaces can be used for the growing of special species of plants (e.g. shrubs) (Urgenda, 2015) that are specially bred to grow quickly, produce more biomass, take in more CO2, save more rain water and absorb more particulates. RECOVERING NUTRIENTS 1. Realising an integrated phosphate strategy The municipality can help realise a closed phosphate cycle. The municipality ought to encourage industrial symbiosis and technological innovation in order to achieve this. Residual streams containing phosphate should be matched up with parties with a demand for phosphate. First steps in this direction have already been taken in projects that involve AEB, ICL and Waternet, among others. 2. Promoting decentralised waste-water management systems This enables the local recovery of heat, energy and resources. Research done in Buiksloterham has shown how the urban environment can be set up at a neighbourhood level to allow decentralised reception of waste and water (Amsterdam Smart City, 2015). It should include, for instance, the separation of waste water types (grey, yellow and black water) and the local valorisation these streams. The municipality can build on this research.

The municipality can further develop and make publicly accessible a digital (commercial) platform for organic waste. Such a platform can offer a transparent overview of the supply, demand and use of organic residual streams in Amsterdam (and beyond). In addition, it can address the uncertainty in the market by improving the matching of supply and demand. This may be a response to the current uncertainty in market participants about supply and demand of flows. The lack of understanding has been mentioned as an obstacle to planning by many of the regional stakeholders, which, in turn, affects the financing due to supply risks. The platform would provide insight into fluctuations in supply and demand on the basis of, for example, seasonal variations in the availability of green waste. The municipality can also stimulate innovation concepts, linking small and large businesses.
The municipality can initiate circular free zones. This could take away certain (legislative) barriers that currently hinder innovation, such as the ban on the use of nutrient-rich digestate (especially phosphate) on agricultural land. This is currently blocking an important and essential part of the business case for anaerobic digester plants because the current market value of digestate is low.
The municipality can introduce criteria in its purchasing policy to stimulate locally produced grass, wood (as in street furniture) and food (catering). The large buying power of the municipality itself can create an important and constant demand that allows local parties to further develop and professionalise. With the local production of biomass and food, the need for transport and its associated environmental impact is reduced (PBL, 2013). The local production of wood can take place in the municipal green facilities of the city (Municipality of Amsterdam, 2014a). To increase the production of biomass in the municipal green facilities, a more holistic approach to the management of municipal green and waste materials is required. Public green spaces can be used for the planting of special species of plants (e.g. shrubs) (Urgenda, 2015) that are specially bred to grow rapidly, deliver more biomass, take in more CO2 and absorb particulates.
The AMS-run program ‘Urban Pulse’ has initiated planned activities around the mapping of resource streams such as organic residual streams into spatial maps. There are also activities within the municipality around providing insight into waste streams associated with geo-data. In addition to this, the municipality can engage with organisations that use big data and have great potential for the circular economy (Lacy, 2015), such as Wageningen UR and AMS, who conduct research into the use of big data (Top, 2015).
It is important that new projects build upon and are linked with pre-existing pioneering activities in the region. One such example is the Greenmills site, a consortium of six companies active in the further development of bio-refinery concepts and the optimal reuse of organic residual streams. Furthermore, Waternet and AEB are involved in and well informed about local initiatives including the processing of sewage sludge for biogas production.
There are several companies and initiatives in Amsterdam that produce local biomass such as food as well as fibres for products. In order to achieve higher volumes of these local products, the municipality needs to redirect its purchasing policy. The municipality is already a signatory of the ‘green deal circular purchases’ (Geet, 2013). The theme of circular purchases for the purpose of local production and consumption is also a major topic at Cirkel Stad (Cirkel Stad, 2013).
The investment required to set up a platform is largely for the development of the IT-infrastructure and for the conceptual development of the platform. Although there are many market participants, including large IT parties, that deal with the development of such platforms, the municipality can play the role of initiator. The ‘out-of-pocket’ development costs for a platform can be financed by private and public parties. The effects and impact on the actual volume of processing organic flows through the deployment of the platform will probably take several years before it is of significant size. This is because the development, buy-in and critical mass required by market parties will take time.
The designation of circular free zones could be an effective way to neutralise the barriers described in the local barrier overview. It is a measure that requires investment, especially in organisation, supervision and enforcement. The measures to be taken fall completely within the terms of the Municipality Act.
The effects of these measures may soon be visible since there is a direct market demand for local products.

CREATION The total economic activity of the Amsterdam metropolitan region amounts to 106 billion euro €23 MILLION annually, of which 47 billion is accounted for by the city of Amsterdam (2013) (CBS, 2015)*. The contribution of the agricultural sector to the city of Amsterdam amounts to 248 million euro and the contribution of the food sector amounts to 593 million euro. The current recycling of organic residual streams in Amsterdam provides a lot of VALUE room for optimisation. The city of Amsterdam CREATION has ambitions to increase the source separation €25 percentage to generate more MILLION value from the organic residual streams in household and industrial waste. Moreover, organic wastes from the food processing industry in the port area offer opportunities for higher quality processing and can, thus, contribute to additional value creation.

The results provide insight into the effects of the implementation of these circular strategies on economic growth, employment, the saving of material use and the reduction in greenhouse gas emissions.
The ‘circular scenario’ can contribute to autonomous (linear) growth in Amsterdam through both the direct and indirect effects of circular strategies. Reprocessing organic material flows to raw material for bio-plastic could, for example, result in cost savings that enable investment in additional improvements. In the

In this study, value creation of circular initiatives is compared to the total added value at basic prices, NOT to the Gross Regional Product. In this chapter, a TNO-analysis is applied, and the assumptions used are from the following sources: Chiewa, et al. (2014) ‘Environmental impact of recycling digested food waste as a fertilizer in agriculture—A case study’, Resources, Conservation and Recycling; Vandermeersch, et al. (2012) ‘Environmental sustainability assessment or food waste valorisation options’, Department of Sustainable Organic Chemistry and Technology; Leceta, et al.

The material savings consists mainly of materials that can be replaced by higher-value processed flows. An example of this is the production of highvalue protein to replace imported protein such

The potential economic and environmental impact of a circular construction chain in Amsterdam compared to a linear scenario is calculated for Amsterdam. Here, the impact will be realised over a period of five to seven years. Four indicators have been used in determining impact: (1) net added value in millions of euro, (2) net job growth in FTE, (3) material savings calculated by value retention in domestic material consumption and (4) reduction in CO2 emissions. The values for the four indicators are shown in the four circles. The distribution in added value is shown in the bar chart.
SCALABILITY MAP The scalability map shows the organic residual streams chain where opportunities lie for four circular strategies: (1) waste separation and return logistics, (2) cascading of organic flows, (3) recovery of nutrients and (4) bio-refinery hub. Green markings show places where household waste is released and, thus, where the potential lies for separation and return logistics. Green and yellow points indicate supermarkets and street markets and reflect the potential for cascading in retail and industry. In addition, large multinationals and food processors are displayed on the map to indicate opportunities for the industry.
4. CURRENT STATE To create a circular economy, we must first understand what is not circular in our current economy. This chapter provides insight into how resources move through the city, where they will be processed to add value to the local economy and where resources are wasted or cascade back into the system to be reused. To reach this understanding, the region was looked at in terms of material flows, energy consumption and employment. The various streams were then examined in order to identify which areas of circularity, quality of life and economic vitality can be improved in the city. For example, where is waste created? And where are the short and long term opportunities to convert these into opportunities for the city and the region? To get a more detailed picture of the â€˜non-circularâ€™ situation at present, we conducted an analysis based on regional and national statistics supplemented with specific organisational data.
One of the challenges in determining a strategy to create a circular economy is measuring circularity and gaining a good understanding of the status quo. For measuring the circularity of the city, region and sectors, the ‘circular indicators framework’ was developed by Circle Economy and TNO. The framework describes four main indicators that provide insight into the essential aspects of circularity. The first three indicators were evaluated using quantitative data provided by CBS and TNO. The indicator for transition potential was investigated by means of interviews and qualitative reviews of specific companies, organisations and other stakeholders within their respective chains. This framework was also used by Circle Economy and TNO for establishing the priority chains for a national project with the Ministry of Infrastructure and the Environment. The four key indicators, with each specific subindicator, are represented on the right. In the figure opposite is an overview of the results of the framework applied to the thirty sectors that CBS differentiates in the macro-economic statistics of the region. Per sector, the figure indicates how big the ‘economic added value’ is to the regional economy (y-axis), what the ‘ecological impact’ is (x-axis) and how big the potential is for value retention (size of the bubble).

FLOWS THROUGH THE METROPOLITAN REGION
The material flows for Amsterdam are analysed and visualised in the following diagram. This figure provides insight into how resources move through the metropolitan region and city, where they will be processed to add value to the local economy and where resources are wasted, or, ideally, cascaded back into the system to be reused. From this review, three important aspects - which are largely linear but which have the potential to create a circular economy in the region - appear to determine the current status.

The supply of materials is vulnerable to strong price fluctuations and distortions in the geopolitical context The high trading volume in the MRA offers economic opportunities but, at the same time, exposes the MRA to disruptions in supply. In addition, the import of biomass from abroad has significant negative consequences for the environment, due to non-sustainable land use and agriculture in South America and other regions.
Large flows of organic and mineral waste originate from industrial waste Of the waste that is produced in the MRA, only a small part is collected through the municipal system as household waste - see Figure 4.3 for further details. (CBS, 2015b). One-sixth of the 6 million tonnes per year is municipal solid waste, consisting mainly of minerals and organic waste (in Amsterdam 14% is household waste and 86% is industrial waste). Non-municipal waste amounts to about 5 million tonnes a year and consists mostly of organic waste. This offers opportunities for bio-refinery applications for high-value use of both municipal and non-municipal residual streams. Waste in Amsterdam is, to a large extent, processed in a relatively low grade One third of the total waste is incinerated to generate electricity and heat. This creates less value compared to recycling or reuse. For domestic waste, the rate for ‘useful reuse’ as defined by the CBS is 85%. This includes activities such as the use of granulated demolition and construction waste for road foundations, which, in a circular economy, can be regarded as a low-value application of recycling. Through high-value reuse, recycling and composting, more value can be extracted from these waste streams.
LOGISTICS HUB The metropolitan region is highly dependent on imports of resources In the metropolitan region, 10 million tonnes of material are consumed annually, of which 60% is imported from abroad, see Figure 4.1 and 4.2 for further details (CBS, 2015b). More than 50% of the import consists of fossil fuels, used mainly in the petroleum industry for the production of plastic.
Matrerial import and export (kiloton)
The food and construction sectors have a relatively low use of circular services Circular services are sectors that are focused on product design, rental, repair and recycling. The average use of circular services in the Amsterdam metropolitan area is 14%. The construction- and food chain is slightly below the average, making use of only 12% and 13% of circular services respectively.
Use of materials and processing of by-products Use of materials in the making and processing industry is dominated by biomass and minerals In the metropolitan area, more than 10 megatonnes of materials – of which 40% is biomass and 40% is fossil fuels – are consumed annually (CBS, 2015b). Biomass is used mainly by industry (70%) and the agricultural and food sector (20%). A large part of the biomass use is allocated to the extensive food and beverage industry. Minerals such as coal are mainly used in the utility sector (74%) and industry (17%) (CBS, 2015b). Metals are mainly used in industry (90%).
Import en export van materialen (kiloton)
ECONOMIC PERSPECTIVE The import, processing and transport of materials and goods is an important economic activity in the metropolitan region The Amsterdam metropolitan area has the largest seaport and airport in Europe. Through these two ports combined, more than 100 million tonnes of goods are imported and 30 million tonnes are exported annually (Port of Amsterdam, 2013). The gross added value of the seaport amounted to 3.5 billion euro in 2012, which was derived mainly from business and industry, including the metal industry, and the transport and logistics sector. For Schiphol Airport, the gross added value in 2012 amounted to 5 billion euro (Ministry of I and M, 2015). The total direct employment of the Amsterdam seaport is 34 thousand jobs; for Schiphol it is 65 thousand (Port of Amsterdam, 2013).

PRIORITISATION OF CONNECTING FACTORS IN A CIRCULAR ECONOMY
Loon op Zand
To understand the extent to which various chains contribute to the economic and ecological impact in Amsterdam, a chain analysis has been conducted. This chain analysis provides insight into the connections between sectors in an economy, such as the connection between the materials (physical flows) and economic value (monetary flows). An example of this can be seen in the production of oil, which is linked to the production of plastic from this oil, which is then linked to the use of plastic packaging material in the food chain, and later linked to the waste treatment of plastic packaging. Exploring which of the chains between sectors result in large impacts is a starting point for prioritising possible interventions. The four indicators used to measure impacts from the ‘circular indicators framework’ have been explained in the beginning of this chapter. For the economical and ecological impact and value retention, a comprehensive analysis was conducted, linking hundreds of value chains and sectors together. The ten chains with the highest impact or the greatest potential were selected. Stakeholder interviews were used to assess the
transition potential. The ten value chains are shown in the table below, with shades of blue indicating the potential impact. Of the ten chains, six are included in the final analysis. After consultation with the municipality and local stakeholders, the decision was made to focus on the construction chain and organic residual streams, as these have the highest economic and ecological impact, as well as the highest value retention and transition potential. The analysis of the value chains serves not only to achieve a transparent selection of important chains at which circular initiatives should be focused, but also provides an overview of economic sectors and actors that are associated with that particular chain. These actors can be a source of inspiration in the development of concrete projects in the Amsterdam metropolitan area. Opposite is a representation of a non-exhaustive and select group of actors for the construction chain and organic residual streams chain.

INDICATORS CIRCULAR ECONOMY This page represents how the city of Amsterdam, the metropolitan region and The Netherlands score on three indicators: value retention, economic impact and ecological impact. Together, these three indicators give an initial idea of how, on a city-level, circularity could be measured. The three indicators were developed in the context of RACE (Realisation or Acceleration towards a Circular Economy), a program initiated by the Ministry of Infrastructure and the Environment. A summary of the indicators is presented later. Previously, TNO
and Circle Economy calculated these indicators at the national level. The value retention is estimated according to resource efficiency: the amount of waste that is produced to generate an added value of 1000 euro. The economic impact is measured in added value per person and the percentage of circular services in the economy: the proportion of the added value in an economy that is generated by services focused on product design, rental, repair and recycling. The ecological impact is measured by environmental costs and CO2-emissions.
RAW MATERIAL EFFICIENCY Raw material efficiency indicates possible waste reduction in production of goods, measured in kilograms of waste per €1,000 output
GROSS VALUE ADDED
ENVIRONMENTAL Environmental costs are the costs of exhaustion, water pollution, CO2-emissions, toxicity and land use in € per kilogram
Gross Value Added per person is the economic value in € per person
USE OF RENEWABLE RESOURCES The use of renewable resources is the percentage of imports (net and domestic) consisting of biomass compared to total imports AMSTERDAM
CIRCULAR SERVICES Circular Services is the percentage of services - related to the circular economy - compared with the Gross Value Added
CO2-EMISSIONS CO2 emission is the amount of carbon dioxide which is released into the atmosphere in kilograms of CO2 per person
5. RECOMMENDATIONS AND NEXT STEPS
The roadmap and action agenda presented in this Quick Scan offer a starting point, giving concrete direction to the ambition, vision and agenda on the theme of a circular economy for two specific value chains – construction and organic residual streams. The municipality can focus on expanding the details of these plans as a next step. Stakeholders, both within the government and in the market, will need to be engaged to actually take action on the proposed directions. Listed below are some next steps advised for the municipality. Further development and selection of indicators that provide insight into the level of circularity in the city of Amsterdam can be undertaken. This basic set of indicators can be used, among other things, to measure progress. The applied ‘circular indicators framework’ in this study (Chapter 4) can give direction to the next steps. The indicators can be applied in an interactive circularity dashboard that displays the progress of the most important indicators. The dashboard can be used internally, but can also involve inhabitants of the city more actively on the subject of a circular economy. In addition, Amsterdam can (in the future) benchmark against other cities on their circular performance.
To come to a detailed feasibility of the proposed actions, more analysis is needed. This analysis can include, for example, a detailed (social) cost-benefit assessment for the various parties needed for implementation. Next steps in the investigation of opportunities for the city and region are part of the program ‘Urban Pulse’, which is led by Amsterdam Metropolitan Solutions (AMS) and Circulaire Stad. The need for greater transparency and a better understanding of the demand of (secondary) resource flows in the region and beyond is mentioned by many stakeholders as a condition for a circular economy, particularly for an optimal exchange and high-value processing of streams. Further development of (geographically explicit) digital material platforms would be crucial to connecting the supply and demand of residual streams and materials. Related to the previous point, there is also a need for active coordination to match supply and demand. The municipality could potentially explore the appointment of chain directors who would be responsible for active matchmaking.
