| Technology description including background system | This dataset refers to the production of one piece of steel fitting with a mass of 2,63 kg per piece. The main component is a steel sheet element (including pre-assembly). The system boundary is the finished window fitting at the factory gate. Transports from the factory to the construction site are not taken into account and have to be incorporated in a system approach. In the disposal phase, mechanical dismantling is accounted for in module C1 for steel products (excavator), for all other metals a manual dismantling is assumed (no loads). 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. The transport in module C2 to the treatment plant takes place with a truck (50km). 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). |
