Recycling (mechanical)

With the recycling of industrial production waste, i.e. sorted sprues or rejects are collected, grinded and reprocessed. The reprocessing is a melting process for the production of granules with constant particle size. Without using additives a regranulate is produced, by using additives, i.e. to match specified mechanical properties, a compound is produced. This new regranulate or compound can be used the same way as prime material and is retuned to the circulation. The use of recyclates versus prime material also reduces CO2 emissions, i.e. Polyamide more than 7 kg CO2 emissions per used kilogramm recycled material instead of prime and thus makes an important contribution to environmental protection.

The mechanical recycling of household waste works in principle the same way with additional step of pre sorting one ore more cleaning steps. So collecting, sorting, shredding, wet grinding or washing and reprocessing by melt filtration. Du to impurities of the input raw material, the yield of recyclable granules is much lower.
