Secondly, we benefit from our long-lasting cooperation with main suppliers of plastics recycling
Rassi says of the system, “In the meantime, we know that our decision to accept the offer from Lindner was absolutely correct. The complete system began operating September 2016 after a six-month lead time. Water and energy consumption are even lower than expected, and the performance and end product are outstanding.”
