| Teknologibeskrivelse, herunder baggrundssystem | BGreen-it Sedum trays provides a fully established green roof from the start and is carried out in a single work step. The trays are simply laid out directly on the roof membrane. The trays are produced from PET 100% recycled plastic, which is very resistant to heat and cold influences. The size of one sedum tray is (LxWxH): 370 x 570 x 60mm. Weight of unsaturated tray (dry): ~25 kg/m2. Weight of saturated tray: ~50 kg/m2. Water storage capacity: 50 Vol. % Retention (System maximum water retention capacity): 25L/m2. Fire resistance class for growing media-substrate (EN 13501-1): B(roof)t2 Further technical information can be obtained by contacting the manufacturer or on the manufacturer's website: www.byggros.com. Guarantee of Origin – certificates Foreground system: No GO certificates are used. The electricity production is modelled using electricity residual mix. Background system: Upstream and downstream processes are modelled using electricity grid mix. The product stage comprises the acquisition of all raw materials, products and energy, transport to the production site, packaging and waste processing up to the ”end-of-waste” state or final disposal. The LCA results are declared in aggregated form for the product stage, which means, that the sub-modules A1, A2 and A3 are declared as one module A1-A3. The A1 raw materials are delivered in bulk to the production site. The soil substrate mix consist of a compost mix delivered by truck from Horsens municipality and pumice stone delivered from Mt. Hekla on Iceland with ship and truck. The compost is derived from garden and park biowaste. The soil substrate mix is mixed at the production site. The trays are made of secondary PET granulate and delivered by truck from ST Plast in Denmark. At the production site water is used. The production site gets the water from a nearby lake, so only the electricity used to pump the water is included as well as the impacts associated with the water depletion potential. Fertilizer production and nutrient supply during the production phase (A3) is included. Diesel used for machinery at the production site is included. If there is waste from the bulk material like compost mix, it is recycled at the production site. The final products are delivered on pallets and wrapped in PE film/net. Inputs for the packaging materials are included in A3. When the trays are delivered, they have a finished sedum plant cover, which means that the sedum seeds/cuts used have grown, which is included in the input under the input Plant/water to account for the weight during transport. The biogenic carbon uptake during the growth and subsequent re-emission into the atmosphere throughout the life cycle is not included in this EPD. Construction process stage (A4-A5) includes: The primary market is Denmark. For the A4 transport, a transport distance of 98 km with truck is used. This corresponds to the transport distance to Copenhagen (DK). The BGreen-it sedum Trays are manually placed on the roof, so no installation energy is included in this study. Packaging material is sent for either incineration or recycling according to EUROSTAT data for packaging waste in Denmark. The credit related to energy recovery from incineration or material credit for recycling are included in module D. Use stage (B1-B7) includes: Not included. End of Life (C1-C4) includes: Like the installation, the demolition is done manually. A distance of 60 km with truck is used for C2. The sedum trays can be returned to Byggros A/S through their Takeback system. The trays are collected and transported back to the manufacturing site. Here, the plastic trays are emptied of soil substrate and plant parts, which are reused in the production. The plastic trays are recycled at Recycling DK. The Takeback system ensures that all components of the sedum tray is recycled. No material is sent for final disposal/landfill (C4). Material credits from recycling of material are included in module D. Re-use, recovery and recycling potential (D) includes: For the packaging materials from A5, energy recovery due to incineration of pallets are credited in module D, as well as the part of the plastic packaging sent for incineration. The plastic packaging sent for recycling is credited with the value of Polyethylene high density granulate. For the product sent to recycling in C3, the outputs from trays are credited according to materials. Secondary PET, which enters the system burden-free, is not credited in module D. | ||
