| Technology description including background system | The LCA of prefabricated reinforced concrete stairs considers the production of concrete (C30/37) and reinforced steel. An average density of concrete of 2.4t/m3, a density of steel of 7.86t/m3 and a reinforcement content of 0.6 Vol.-% are assumed. The product is a 1.1 m wide standard stairs with 9 stairs à 16 cm. The system boundary of the finished product is represented by the factory gate. Transports from the factory to the building site are not considered and must be included according to the system boundaries. In the disposal phase, a mechanical dismantling (excavator) is assumed in module C1. The transport in module C2 to the treatment plant takes place with a truck (50km). In module C3, the material is processed, any reinforcement is fed to a sink (no loads, no credits). A treatment loss of 25% was assumed. This loss is fed to an inert material landfill within Module C3 (average landfill emissions). In Module D, a credit for the net amount of material (excluding reinforcement and treatment losses) for the substitution of natural gravel as backfill material is given. |
