| Technology description including background system | The EPD covers all products listed below. • Autoclaved aerated concrete blocks with a dry density of 375 kg/m3 , also called Planstein PP 2/040 • Autoclaved erated concrete blocks with a dry density of 535 kg/m3 , also called Planstein PP 4/055. The autoclaved aerated concrete blocks are covered by harmonised technical specification in EN 771-4 and for the EPD it follows EN 15804. Declaration of performance according to EU regulation 305/2011 is available for all declared product variations. Further technical information can be obtained by contacting the manufacturer or on the manufacturer’s website: https://www.hplush.dk https://www.hplush.de. Guarantee of Origin – certificates No guarantees of origin or certificated are used for green electricity or energy production. For modelling energy production, the country specific residual mix is used, in accordance with the recommendations from EPD Denmark 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 raw materials used in the production of the autoclaved aerated concrete elements has been pre-treated, manufactured, and provided by suppliers. These materials are then dosed and mixed in the mixer to form an aqueous suspension. The mixture is poured into casting molds, where air pores are created with chemical reactions. The homogeneous structure is exposed to a saturated steam atmosphere to form specific characteristic properties for the autoclaved aerated concrete products. Construction process stage (A4-A5) includes: A4 – transport to the building site A5 – installation into the building This includes the provision of all materials, products and energy, as well as waste processing up to the end-of-waste state or disposal of final residues during the construction process stage. The autoclaved aerated concrete blocks are installed manually as predefined elements using no auxiliary materials or machinery. The autoclaved aerated concrete blocks are installed in Europe. A flat amount of construction waste is assumed for all products equal to 2%, which is added to the output from the production. The declared product is thus the inclusion of the construction waste in the product. Use stage (B1-B7) includes: The use stage, related to the building fabric includes: B1 - use or application of the installed product B2 - maintenance B3 - repair B4 - replacement B5 – refurbishment The use stage take place in Europe and are related to the operation of the building includes: B6 - operational energy use B7 - operational water use These information modules include provision and transport of all materials, products, as well as energy and water provisions, waste processing up to the end-of-waste state or disposal of final residues during this part of the use stage. According to the cPCR these modules do in general not generate relevant environmental impacts and are therefore neglected. For B1 CO2-uptake from carbonation has been calculated based on the reactive CaO specifications on each product and the rate of carbonation set to 95%. Additionally, the autoclaved aerated concrete blocks contain water that is evaporated during the use phase until each block is in moisture equilibrium with the surrounding atmosphere. End of Life (C1-C4) includes: C1 - de-construction, demolition C2 - transport to waste processing C3 - waste processing for reuse, recovery and/or recycling C4 – disposal The autoclaved aerated concrete products are assumed demolished using an excavator (C1). Impacts are accounted for in the form of diesel consumption from the excavator used for demolition, sorting, placement, and additional crushing of autoclaved aerated concrete waste elements in large piles and loading of concrete waste onto a semi-trailer used for the waste transport. At the recycling facility the autoclaved aerated concrete is crushed (C3), where after 95% are recycled and used as road fill. The remaining 5% of the autoclaved aerated concrete is sent to a local landfill (C4) Re-use, recovery, and recycling potential (D) includes: Module D includes the reuse, recovery and/or recycling potentials, expressed as net impacts and benefits. These included the energy produced in A5 (incineration of packaging) and substitution of gravel from the recycling of crushed product, however, only the quantity of the product which constitutes primary material. The added recycled materials in the products have not been credited in D. | ||
