| Technology description including background system | The LCA of the vapour barrier covers the cradle-to-gate phase. The system boundaries are represented by the finished product. 10% of antimony trioxide has been used as flame retardant. Transports from the factory to the point of installation are not considered and must be included according to the system boundaries. Production of PA 6: Nylon 6 is produced from caprolactam which is synthesized from benzene, ammonia, hydrogen and sulphuric acid (oleum). Via the intermediate products cyclohexane and cyclohexanone, the monomer caprolactam is produced. The Nylon 6 is produced by the reaction of caprolactam with water over producing the intermediate product aminocaproic acid. The acid is formed by ring- opening of caprolactam when water is added. Caprolactam and water are therefore heated to 250°C. Nylon 6 is then formed by the copolymerization of caprolactam and aminocaproic acid. The process can be carried out batchwise or continuously. 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. |
