| Technology description including background system | Foreground system: The system boundaries comprise the cradle to gate life cycle of 1m2 of three panes insulation glas without fixing system or frame. The LCI dataset consider the production and assembly of the of the glas panes parts and the side materials (sealing materials, spacers, argon, surface treatment of the glass). Reference product scaled to 1m² Based on 3 sheet glass of 124cm* 99cm, 3 panes of 4mm thick, 2 panes treated (low emission coating) 16mm between panes. Sealing, spacer and argon (between each pane)Transportation processes for the raw materials are accounted for as far as data on average transport distances were available. All relevant energy and energy flow are included in the system. Life cycle impacts of production equipment and infrastructure were not included in the system as no evidence could be justified that these are to any extent relevant and thus fell under the cut-off criteria. In mass production the impact of production equipment and infrastructure normally is in orders of magnitude lower than the impacts of material and energy supply. In module C1, a manual dismantling (no loads) is assumed, collecting losses are neglected. The transport in module C2 to the recycling plant takes place with a truck (50km). Tratment of metal components: Collecting losses are neglected. It is assumed that all metals reach the end of the waste status immediately after dismantling. This means that the loads for processing and the credits for the substitution of primary material are shown in Module D. Module D includes loads for sorting, remelting, slag treatment, landfill, filtration of dusts and dross treatment. Credits are given for the net scrap amount (amount returned minus secondary material content, minus processing losses) for the average material mix (from different alloys). Treatment of plastic components: Module C3 takes into account the grinding and thermal treatment (combustion) of the material. When calculating combustion emissions and credits, the specific calorific value of each material and the material composition are taken into account. In module D credits for the substitution of electricity (German electricity mix) and thermal energy (from natural gas) are given. Treatment of renewable raw materials: Module C3 takes into account the grinding and thermal treatment (combustion) of the material. It is assumed that the material reaches the end of the waste status immediately after dismantling. The CO2 absorbed and stored in the material by photosynthesis (from module A1) is written off in C3 (CO2 neutrality within the product system according to EN 16485: Round and sawn timber - Environmental Product Declarations - Product category rules for wood and wood-based products for use in construction, 2014). Module D contains the loads through the operation of the recovery facility (excluding biogenic CO2, see above) and credits for the substitution of electricity (German electricity mix) and thermal energy (from natural gas). The calculation of combustion emissions and credits takes into account the specific calorific value of the material and the material composition. Treatment of inert material components: In module C4 the average landfill emissions corresponding to the product (reference country Germany) are shown. The use of landfill gas is not taken into account. |
