| Use advice for data set | Scope: This document refers to the production of 1 kg uncoated "FOAMGLAS® F" cellular glass manufactured in Belgium at the Tessenderlo production facility of Pittsburgh Corning Europe NV. The environmental impacts of the coated product "FOAMGLAS® F" are to be assessed with the help of a markup factor in the amount of 13%. This document is translated from the German Environmental Product Declaration into English. It is based on the German original version EPD-PCE-20150041-IBA1-DE. The verifier has no influence on the quality of the translation. System boundary: Type of EPD: cradle to gate The LCA addresses the life cycle stage of production. The product stage comprises Modules A1 (Raw material supply), A2 (Transport) and A3 (Production). The following individual processes were included in the product stage A1–A3 of production: · Processes for providing preliminary products and energy · Transporting the raw materials and preliminary materials to the plant · Manufacturing process in the plant including energy-related expenses, disposal of residual materials and emissions · Production of packaging The packaging material volumes considered involve annual consumption / annual purchase volumes. Module A4 takes account of transportation to the construction site. The utilisation of the packaging materials is assigned to Module A5. Environmental effects caused by installation losses are not included in the LCA results, since these depend on the construction project and thus vary. To calculate the additional environmental burdens caused by the production and disposal of these installation losses, the LCA results for a specific installation loss can be calculated (e.g. installation loss 3%, multiplication of the LCA results by 1.03). Landfilling with residual materials is assigned to Module C4. Credits based on the thermal utilisation of the residual materials are assigned to Module D. |

| General comment on data set | FOAMGLAS® is an insulating material made of foamed glass for building construction and industrial installations. It is used to manufacture dimensionally-accurate slabs, boards, pipe shells, segments and other special elements. FOAMGLAS® slabs and elements are largely manufactured from high-quality recycled glass (e.g. windscreens) and mineral base materials such as sand and without the use of binding agents. They display a closed-cell structure. The product FOAMGLAS® F is declared with a gross density of 165 kg/m³ (± 15 %). The products are supplied in thicknesses of 40 mm to 160 mm, e.g. as slabs with high compressive strength. The use of coated or uncoated FOAMGLAS® is application-dependent. The uncoated slab is frequently used for interior insulation, and then coated with various types of plaster. For roofs, FOAMGLAS® is either coated with hot bitumen before the waterproofing membranes are applied, or special boards are used, for example FOAMGLAS® READY BOARD. This ex-works coating is a thin bitumen coating combined with foil or non-woven fabric. The products by Pittsburgh Corning Europe NV are produced in the Tessenderlo plant (Belgium). |

| Technology description including background system | A first step involves weighing, crushing and mixing the raw materials followed by melting at 1250 °C in the electrode furnace. Using electrical energy for melting guarantees a homogeneous melt. Once the melt has cooled, the glass is finely ground in ball mills with the aid of corundum cylinders. Some of the recycled glass used can be ground and foamed directly without necessarily being melted first. It is combined with the pretreated powder mixture and poured into foaming moulds made of stainless steel. The mixture then runs through a foaming process at 850 °C followed by a controlled cooling process. Stressless cooling is followed by cutting and packing. Production process: 1 Mixing and batching of the raw materials: Recycled glass, feldspar, sodium carbonate, iron oxide, manganese oxide, sodium sulphate, sodium nitrate. 2 The melting furnace has a constant temperature of 1250°C. 3 Molten glass is drawn out of the furnace. 4 Control room for monitoring the production. 5 The glass is drawn off and falls onto the conveyor band where it cools down before entering the ball mill. 6 Addition of "carbon black". 7 Ball mill grinds all ingredients into a fine powder before putting them into stainless steel moulds. 8 The filled moulds pass through a cellulating oven (foaming furnace) with a temperature of 850°C. This is where the material gains its unique cell structure. 9 Energy recovery of heat. 10 The FOAMGLAS® blocks pass through an annealing oven to allow carefully controlled cooling without thermal stress. 11 The blocks are cut to size and sorted by batch. Production waste is recycled. 12 FOAMGLAS® slabs are then packaged, labelled and palletized. 13 Finished FOAMGLAS® products are stored and prepared for transport. Quality assurance: Quality is assured through internal and external monitoring. The product complies with the Declaration of Performance. It also bears the CEN Keymark certificate in accordance with DIN EN 13167 and DIN EN 13172. Electricity requirements are fully guaranteed by purchasing a certified electricity mix from hydropower plants. Declared unit: The Declaration refers to the life cycle of 1kg FOAMGLAS® F. The gross density of the product is 165 kg/m³. |
