ENTEX goes green. ENTEX has over 35 years of experience in plastic extrusion technology for compounding a wide range of materials. In recent years we have been working with our partner companies, institutes and universities to develop a range of recycling processes that include sewage sludge treatment, waste tyre devulcanisation , film edge trim recycling as well as different depolymerisation and other plastic recycling processes. Complex recycling processes that are increasingly important today have come into being thanks to the wide-ranging possibilities offered by the individually configurable modular construction of the ENTEX extruder system.
