| Technology description including background system | The LCA of butyl joint sealing tapes covers basically the production of polybutadiene rubber. The system boundaries are represented by the finished product at the factory gate, with a density of 1.2g/cm3 and different thickness and width. Transports from the factory to the building site are not considered and must be included according to the system boundaries. The rubber is produced by the polymerization of 1,3,- Butadiene. The reaction is started with an initiator and carried out in a solution or an emulsion. A catalyst, which can be a transition metal like Nickel or an alkyl metal like butyllithium, is used. The reaction is carried out in solvents and is highly exothermic. The solvents reduce the reaction rate and prevent runaway reactions. Either a batch process or a continuous process can be used. 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). 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. |
