Unparalleled urban expansion with increasing eco-awareness
Escalating oil prices and geopolitical changes across the globe are the two most frequently cited factors contributing to the explosive urban growth in the Middle East. Ever stiffer competition between the Emirates and an almost frantic determination to use architecture to create an urban identity are the forces driving the expansion. In this game, Dubai is quickly becoming the most appealing example of a successful recipe for favourable economic development, even for countries and cities outside of the region. The extremely rapid rate of urbanisation seldom leaves room for environmental and social considerations. The amounts of waste produced and energy consumed here are the highest per capita in the world. There is practically no public transportation to speak of and, in the past couple of years, this has caused considerable traffic congestion. Major socio-economic gaps also exist in the region whose expansion depends mainly on inexpensive foreign labour, with most of the workers coming from India. So it is fascinating to observe the dedication with which the leaders in the Emirates are now creating new regulations and structures in order to push these developments in a more sustainable direction. A lot of the projects currently in the pipeline will be some of the world’s leading examples of sustainable city planning within the next few years. The ways in which the Emirates are tackling their problems and the results achieved will have a major impact on many of the rapidly expanding regions around the world. Another fascinating example of sustainable urban development is the project Valdespartera in Saragossa in Spain. Much like in the Middle East this part of Spain has a very dry and windy climate. The determination to make this to a beacon of sustainable development in this part of the world is impressive.

Aldar is working with Envac Envac Middle East has recently been awarded the Yas Island development by Aldar in Abu Dhabi, the capital of the UAE. ALDAR Properties PJSC is a leading property development company in Abu Dhabi. The Yas Island project is predominantly a leisure development centred around an F1 grand prix race course that will be surrounded by theme parks, retail malls and hotel developments around a natural marina. Phase 1 will handle approximately 70 tonnes of waste per day and includes the F1 area, surrounding Marina and hotel
developments and the retail mall. Each of the areas will be separating waste at source into two fractions and the waste will be transported through a 6 km pipe network to 3 collection stations located on the perimeter of the development. The first system will be commissioned in September 2009 prior to the inaugural F1 grand prix which is scheduled for November 2009. This is the second F1 race track to be constructed in the Middle East; the first being in Bahrain and they were eager to avoid the same problems that Bahrain are having
through implementing a conventional truck approach which has resulted in it taking up to three months to remove the waste after the race.

Envac at Expo Saragossa Envac Iberia SA was one of the sponsors of the Swedish pavilion at World Expo in Saragossa in Spain who took place between June and September. One attraction in the Swedish pavilion, which received over 600,000 visitors was a STUFFED moose. Lorenzo, who was by Spanish schoolchildren in a name competition was the most photographed object in the entire
exhibition. Another exhibition item that attracted much attention was Envacs new outdoor inlet NOA, developed by the Spanish organization. The next World Exhibition takes place 2010 in Shanghai with the theme ’Better City - Better Life’. Envac will participate as sponsor of the Swedish Pavillion in Shanghai Expo 2010 as well. in this exhibition.

A gigantic waste challenge
The Gulf States produce 120 million tonnes of waste a year, which means they rank tenth in the world for waste production per capita. The amount of waste is increasing rapidly and, if it continues at this rate, it is expected that by 2014 these countries will be producing the most waste in the world per person each year!
The situation is most critical in the Arab Emirates, particularly in the cities of Dubai and Abu Dhabi. Without an end in sight for the construction boom, Dubaiâ€™s mountains of waste are growing at an alarming rate.
Waste from demolition and construction sites accounts for a significant proportion, having increased by 163 percent in just the past year. Surplus materials from construction and demolition sites represent 75 percent of all waste in Dubai and barely 30 percent of this is recycled. Household refuse grew by 13 percent from 2006 to 2007 and now constitutes 3.34 million tonnes on an annual basis.
What is the best way of getting to grips with the growing problem of waste? Director Hassan Mohammed Makki, who is responsible for the management of solid waste in Dubai, puts the development of a waste strategy for the

city and the improvement of collection logistics and waste treatment at the top of his list of priorities. The goal is to make the urban environment as clean, attractive and hygienic as possible. â€œOur greatest challenge is to keep up with the rapid phase of expansion taking place in our city,â€? Director
aBU DHABI Makki explains. “Because of the fast growth in population, where 70 percent is short-term population, every attempt at accomplishing a change in behaviour is turned into a Sisyphean task. We also have huge numbers of foreign workers from subcontinent and the Middle East. Most of them are unqualified and many are unable to read and write,” Mr

More challenges “Another challenge is to encourage more environmentally-responsible behaviour with regards to waste. Many people ask the question – What’s in it for me? To help them discover the answer, we have launched a number of “recycle and win” campaigns. Every time someone hands in their waste for recycling, they receive vouchers that entitle them to discounts and special offers in Emirates’ Retail Outlets. We are testing different ways of encouraging and increasing recycling. However, the lack of good collection systems and recycling capacity often limits us.” “The dramatically increasing amounts of waste that are being transported also pose a problem. This is where the Envac system has an obvious advantage, since it means the waste can be stored for a longer time and transported at night ”.
In June 2008, Abu Dhabi, the capital of the United Arab Emirates, announced that it would be investing Dh 500 million (about € 80 million) over a period of ten years to improve the collection, recycling and riddance of household and commercial waste in collaboration with the private sector. The investment will partly fund a project, which exists in just two other places in the world, for the production of high-quality plastic from collected packaging. Plastic from up to 2.4 million PET bottles per day will be reused to make food and beverage packaging.
An Australian architect creates green building trends in Dubai The opinion that it was not possible to adapt or upgrade existing Arabic buildings posed one of the greatest architectural challenges in the development of the region. Although the small, low, traditional style dwellings were certainly ideally suited to the extreme climatic conditions of the area, they did not fit in to the local leaders’ lofty plans for growth and development. The Ruler of Dubai, His Highness Sheikh Mohammed Bin Rashid Al Maktoum, and VicePresident of the U.A.E., has realised that such expansion is unsustainable without introducing demands for Barry Swayn, an architect from Australia that came to Dubai in 1996. He is the director of the Design&Architcture – STORM CONSULTANTS. In his background you can see the Masgreater energy efficiency and ter plan of one of his ongoing projects – ”The Palisades”, Dubai Investment Park. environmental awareness.

problem is that architectural design was not respecting these basic environmental principles which were being avoided in large scale development by using antiquated design and construction practices in a region that had grown and was continuing to grow at breakneck speed. Most of the buildings had been constructed without any thermal insulation at all and entirely without consideration for energy efficiency.

ning in the Arab Emirates?
A: Many of the basic assumptions that our society has held in the past, especially the false belief that we have a never-ending supply of cheap oil and the lack of understanding about global warming, have now radically changed. There is no longer any continuity in these thought processes. Politicians and authorities have to reassess their areas of interest and social and community responsibilities. They must ask: “What is best for society as a whole?”.

A: That’s a good question since it underscores the general assumption that it costs more to change to construction that is more sustainable. In recent years, there are consultants that have been developing programmes that evaluate projects and components from a very early stage of conceptual design,
Other aspects that have to be considered are operational and environmental costs. What will it cost to deal with all the materials in the ‘food chain’ that is the construction process, from supply to waste removal to materials that are replaced in renovation and refurbishment? This is a particularly relevant question in this region of the world where we don’t have all the components of the environmental infrastructure that other countries have and where most materials are imported. Construction project evaluations very rarely take replacement costs and the need for long-term maintenance and repair into account. Clients must learn that we must get away from the classic throw-away mentality in this area too, because they will ultimately pay in the long run.
Q: How does Envac’s underground waste system fit into this holistic life-cycle approach?
A: I am amazed there aren’t more people who have realised the advantages of the Envac system. Our project, ‘The Palisades’, focuses on bringing greater efficiency to waste management. From a central point, we will be laying a system of pipes, like a row of fingers to connect all the buildings in the project. We start at the source of the waste, which is in the buildings. We install a twin chute/pipe system in each apartment building that allows for
the recycling of two separate types of waste - wet/non recyclable waste and the other is the recyclable waste, therefore recycling and waste management starts at the source. In this way, we are able to eliminate ‘smelly’ separate waste rooms and the need for ‘noisy’ and ‘smelly’ transport waste collection routes through residential areas. Waste rooms require air conditioning and daily cleaning, they also entail capital investment and management costs - which we would prefer not to incur.
project, thereby enhancing the quality of life for the 34,500 people who will live here. ‘The Palisades’ Project with the Envac Waste Management System educates and encourages users to become more environmentally aware of waste generation, waste management, the social responsibility as a community member towards recycling, and the awareness and custodial responsibility we should demonstrate for our children and their children’s future.

Chaos on the roads in record time Tailbacks that stretch for miles have recently become the norm in Dubai. The astounding rate of expansion that both Dubai and Abu Dhabi have been experiencing has taken place against a background of insufficient road planning and practically a total lack of public transportation. Dubai City is therefore investing in an over ground metro system and has plans to introduce a car toll system - making it the first city in the region to do so. It is rather paradoxical that a region with so much empty space and an almost endless supply of inexpensive petrol has reached the end of the road in terms of transportation. This is because Dubai has expanded almost exclusively along the coast along the Persian Gulf. As a consequence, a great, long stretch of land that is no more than one or two kilometres in width has been developed. There is no natural city centre, building permits have been generously issued and property prices have escalated dramatically leading to increased building density â€“ all of which has created an extreme dependence on cars. And urban development in Abu Dhabi is heading the same way.
Topping the global list for traffic accidents Itâ€™s not just private motoring that is growing at lightening speed. The transportation of heavy goods is also increasing rapidly and the number of lorries and trucks is expected to reach one million by 2015. As a result, trips that normally only take a matter of minutes have turned into hour-long nightmares. The frustration caused by this traffic chaos has pushed up accident figures
to such an extent that Dubai now tops the list for the most traffic accidents in the world in relation to the population density.
and new technology that would extend the underground transportation route by several kilometres and thereby entirely eliminate the need to use heavy vehicles to transport waste by road.
Car pooling now legalised The governments of Dubai and Abu Dhabi are therefore planning a series of measures to address the chaotic situation on the roads. The Road and Transport Authority in Dubai recently announced that car pooling is now legal in the Arab Emirates. The ban on car pooling was introduced in an attempt to control the problem of illegal taxi operations. Another measure that the government is considering is to invest in a railway network that would connect not only the United Arab Emirates but also all countries in the region, including Saudi Arabia
Focus on waste transport Envacâ€™s underground waste system offers a highly attractive solution to the problem of using heavy vehicles to transport waste. In a number of projects, discussions are underway concerning local waste recycling centres

Saragossa - not just Expo
“Ecociudad Valdespartera” (The Environmental City of Valdespartera) was initiated in 2001 when the city of Saragossa and the Spanish Department of Defence signed an agreement which included the development of the 242 hectare area called Valdespartera as part of Saragossa’s general development plan. One key condition in this agreement was that the area would be developed according to bioclimatic principles.
The installation of an underground waste transportation system was considered an interesting option right at the start of the project. The development plans for the area therefore included the possibility of installing an underground waste system, although this was not an explicit requirement.
Extensive preliminary investigations The project management team for Ecociudad Valdespartera decided to visit Majadahonda, Almería and Barcelona, where underground systems were already installed, to give them better insight into what a vacuum transporta-
tion system involved. Neither the city of Saragossa nor the region of Aragon had any prior experience of this kind of technology. The project management team also decided to enlist the services of two consulting firms to review the technical and financial implications that the installation of this technology would entail. This resulted in a cost estimation of €9 million for the investment, with the individual developers’ costs amounting to between €550 and €900 per residence. Operating costs for the system were estimated at €30 per tonne, which was about two-thirds of the average costs of traditional waste collection in Saragossa. The Valdespartera project received a grant of up to €22.5 million after being
Valdespartera average of 25 households per inlet. Twelve collection points, with two inlets each, were also located along the pavements for the single-family houses in the area. In addition, underground tanks were installed at 69 locations for the disposal of paper/cardboard and glass.
Recycling centre in the terminal A 13-kilometre-long network of pipes, divided into two systems, links the inlets to the collection terminal. The system design also provides the capability for managing organic food waste as a separate material at a later stage. All other types of waste, such as electronics, bulky and hazardous waste, can be deposited at a 2,500 m2 recycling station, which is housed in Carlos Bernad, Regional president of Envac South Europe together with the Mayor of Saragossa, Juan Alberto Bell, and the Swedish Ambassador in Spain Mr Anders Rรถnquist at the inauguration ceremony of the Envac system in Ecociudad Valdespartera in February 2007.

Social and environmental
The criteria for sustainability in the development of the area were laid down at the very start.
After four years of intensive work, tenants started moving in during the first three months of 2007. That also meant that the waste system had successfully completed all the preliminary tests. At the inauguration of the system, Juan Alberto Bell, the mayor of Saragossa, declared that “the residents will be extremely satisfied with this state-of-the-art technology that has already proved itself in many towns and cities”. “Furthermore, it will signify a social and environmental breakthrough for this project.” Envac is well aware of the vital role its system plays in creating a sense of comfort in the area and therefore organises regular campaigns to keep the residents updated with information. The objective is to increase the separation of waste at source and thereby reduce the volumes of waste and increase recycling.
• It was stated in the Urban Development Plan that the orientation of the buildings would be planned to achieve maximum solar energy collection, and also create windbreaks and sheltered spaces that enhance the residential environment. • The architectural design of the buildings would allow for the incorporation of solar cells and facades that could act as passive thermal buffers. • Priority was given to materials that provide good insulation and longevity. This resulted in a rectangular network of streets in which the buildings stretched in an east to west direction, facing south and with a space of thirty meters between each one. This provides
excellent protection from the wind and optimum collection of solar energy in the courtyards. Other sustainable principles included separate water systems (for drinking and washing, and for rainwater and waste water) and the choice of recycled materials for park benches, street lighting, playgrounds etc.
Perhaps the most significant innovation that was introduced, however, was the installation of an information system that manages all public operations statistics plus individual comfort and energy consumption data in one single system. It is anticipated that this system will reduce operational costs and help cut energy consumption. It is also hoped that this will support the primary objective of this project - the creation of a role model for the development of innovative and sustainable urban districts.

Waste management is critical An essential part of this gigantic logistics puzzle is waste management. The waste created during the production of meals and from incoming flights has to be disposed of quickly, safely and hygienically. It would be unthinkable to deal with this amount of waste manually. For more than two decades, Envac has been designing kitchen waste systems for practically every major airport in the world. During the production of meals, about 2,5 litres of waste are created per meal and an average of 1,25 litres of waste come back from incoming flights. This means that each meal creates a total of almost five litres of waste. That waste has to be dealt with, and for Emirates Flight Catering, this means almost 100 tonnes of waste every day. Envac is the supplier of the waste systems used at both flight catering facilities at Dubai International Airport:
• The first system was up and running in 2004 and has a total capacity for 60,000 meals with Envac’s system handling the food waste from incoming

The waste system for the new facility is divided into three sub-systems: 1. A system with 200 mm pipes for waste from the trays from wash lines 1-4 2. A system with 200 mm pipes for waste from the trays from wash lines 5-8 3. A system with 200 and 300 mm pipes for waste from meal production with two carousels for 60 litre sacks. There are also screw feeders in the food preparation kitchen and in the staff canteen, a waste grinder for more bulky waste and two chutes with water drainage screws for packages.
Emirates Flight Catering is extremely satisfied with their Envac waste systems. “The fact that we commissioned Envac to build the waste system for our new flight catering facility is full proof that we have great confidence in this technology. The systems work extremely well and play a key role in ensuring that our operations remain efficient,” John Earnshaw, Head of Flight Catering Operations at Dubai International Airport concludes.
