PRODUCT LIFE-CYCLE

SYSTEM BOUNDARY

This EPD covers the life-cycle modules listed in the following table.

MANUFACTURING AND PACKAGING (A1-A3)

The environmental impacts considered for the product stage cover the manufacturing of raw materials used in the production as well as packaging materials and other ancillary materials. Also, fuels used by machines, and handling of waste formed in the production processes at the manufacturing facilities are included in this stage. The study also considers the material losses occurring during the manufacturing processes as well as losses during electricity transmission.

A market-based approach is used in modelling the electricity mix utilized in the factory.

Energystore TLA+® is manufactured following a 2 stage steam expansion process, using raw grey expanded polystyrene (EPS). The key steps to the manufacturing process are set out below:

• Raw EPS is received from suppliers typically in sealed containers of 1.1tonne per container. The material travels by road 930km from the supplier to energystore’s manufacturing facility.

• The EPS is fed into the expansion machine using a sealed screw. This feeding process ensures the EPS is fed into the expansion machine at the correct rate to ensure accurate product density.

• Once the EPS is within the expansion chamber, it circulated with low pressure steam of temperatures between 85 – 100 degrees Celsius. Once the material has circulated sufficiently to achieve the desired 1st stage density, it is fed from the expansion chamber through a sealed drying bed enabling any excess moisture to drain from the eps beads.

• The material is then blown from the drying bead through a series of sealed pipes to be kept in storage silos for a period of time. Once the material has stabilised and dried, it is blown back through a series of sealed pipes to be fed back through the expansion chamber and drying bed, repeating the expansion process for a 2nd time to achieve the final desired product density.

• At the end of this 2nd stage expansion, the material is again blown through sealed piping to final storage silos.

• Once the material has cooled, it is then fed through silos to the

spraying machinery which is used to apply an additive coating to the eps.

• After spraying of the additive, the product is ready to be shipped. The material is again blown through sealed pipes into specially designed, sealed transport vehicles. The material is then delivered to installing companies, typically in shipments of 120m3. As the material is shipped in specialist vehicles, there is no packaging necessary for the product.

• As the material is handled in sealed expansion chambers and transfer pipework there are no production losses. In the event of a spillage at the manufacturing site, the raw material can be collected using vacuum equipment and put back into the manufacturing cycle. As a result, there are no manufacturing losses in our processes.

A residual mix approach is used in modelling the electricity mix utilized in the factory. A market-based approach is used in modelling the natural gas mix utilized in the factory.

PRODUCT END OF LIFE (C1-C4, D)

At end of life, the material can be removed from construction sites prior to demolition. This process involves breaking the material into chunks and transported to waste processing sites. The polystyrene can then be easily separated from the light cement mortar using a scrubbing process. Once this is complete, the material is ready for recycling or incineration. Demolition is assumed to consume 0,01 kWh/kg of product. The source of energy is diesel fuel used by construction machines (C1). It is assumed that 100% of the waste is collected and transported to the waste treatment center. Transportation distance to treatment is assumed as 50 km and the transportation method is assumed to be lorry (C2).

EPS recycling: 9 % recycling rate assumed (source: Plastics Europe (2020) https://plasticseurope.org/knowledge-hub/plastics-the-facts-2020/; C2 transport: 50 km assumed (source: Gervasio, H. & Dimova, S., JRC Technical report: Model for Life Cycle Assessment (LCA) of buildings, 2018)

EPS landfill: 32 % landfill rate assumed (source: Plastics Europe (2020) https://plasticseurope.org/knowledge-hub/plastics-the-facts-2020/; C2

transport: 50 km assumed (source: Gervasio, H. & Dimova, S., JRC Technical report: Model for Life Cycle Assessment (LCA) of buildings, 2018)

EPS incineration: 59 % incineration rate assumed (source: Plastics Europe (2020) https://plasticseurope.org/knowledge-hub/plastics-the-facts-2020/; C2 transport: 50 km assumed (source: Gervasio, H. & Dimova, S., JRC Technical report: Model for Life Cycle Assessment (LCA) of buildings, 2018)

Module D incineration benefits modelled on avoidance of electricity generation from European averages and thermal benefit for heat in the UK (Market for heat, district or industrial, other than natural gas (Reference product: heat, district or industrial, other than natural gas)).

Module D recycling benefits modelled based on avoidance of typical European virgin EPS production.

LIFE CYCLE FLOW DIAGRAM

LIFE-CYCLE ASSESSMENT

CUT-OFF CRITERIA

The study does not exclude any modules or processes which are stated mandatory in the reference standard and the applied PCR. The study does not exclude any hazardous materials or substances. The study includes all major raw material and energy consumption. All inputs and outputs of the unit processes, for which data is available for, are included in the calculation. There is no neglected unit process more than 1% of total mass or energy flows. The module specific total neglected input and output flows also do not exceed 5% of energy usage or mass.

The production of capital equipment, construction activities, and infrastructure, maintenance and operation of capital equipment, personnelrelated activities, energy and water use related to company management and sales activities are excluded.

For easier modelling and because of lack of accuracy in available modelling resources some constituents under 1% of product mass are excluded. These include some ancillary materials which are all present in the product only in very small amounts and have no serious impact on the emissions of the product.

This LCA study includes the provision of all materials, transportation, energy and emission flows, and end of life processing of product. All industrial processes from raw material acquisition and pre-processing, production and end-of-life management are included.

VALIDATION OF DATA

Data collection for production, transport, and packaging was conducted using time and site-specific information, as defined in the general information section on page 1 and 2. Upstream process calculations rely on generic data as defined in the Bibliography section. Manufacturer-provided specific and generic data were used for the product’s manufacturing stage. The analysis was performed in One Click LCA EPD Generator, with the 'CutOff, EN 15804+A2' allocation method, and characterization factors according to EN 15804:2012+A2:2019/AC:2021 and JRC EF 3.1.

A technical inconsistency has been identified between PENRT (Total use of non-renewable primary energy) and ADP-fossil (Abiotic depletion potential for fossil resources) results in modules A1–A3. A contribution analysis shows that the remaining discrepancy originates from the specific characterization factors in the background environmental profiles of the primary raw materials (datapoint). These inconsistencies are inherent to upstream data from specific supplier and cannot be adjusted by the practitioner.

ALLOCATION, ESTIMATES AND ASSUMPTIONS

Allocation is required if some material, energy, and waste data cannot be measured separately for the product under investigation. All allocations are done as per the reference standards and the applied PCR. In this study, allocation has been done in the following ways:
