| Technology description including background system | The life cycle analysis of the EVA roof sheet (ethylene -vinyl acetate copolymer) includes the life cycle phases cradle to gate. The system boundary is the product (ready for sale). Transports from the factory to the mounting location are not taken into account and have to be incorporated in a system approach if necessary. EVA production: EVA is produced by the copolymerization of ethylene and vinyl acetate. The reaction takes place in the solution, catalyst and initiator are used. The reaction temperature is between 40 and 80°C, the temperature shouldn`t get to high because of the strongly exothermal reaction. 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. |
