Company history

When the oil crisis temporarily caused the raw material price of plastics to rise sharply at the beginning of the 1970s, a new market for recycling systems also emerged. Heinrich Koch, the founder of SIKOPLAST saw this as the future for his company and from then on developed the plant engineering and systems for the recycling of plastics. This development was consistently continued by SIKOPLAST, even when other engineering companies discontinued to follow this trend. One of the heart pieces of this success are the conical single-screw extruder. This screw design, which has often been copied, forms the heart of the SIKOPLAST recycling systems even today in a modified design.

In 1986 the foundation stone of today's SIKOPLAST Recycling Technology was laid. The delivery program of the company SIKOPLAST has been continuously expanded since then. In addition to conventional recycling systems for processing all kind of thermoplastics, production waste, washing systems and parts for processing of post-consumer waste, as well as silos, conveyor belts, screen changer units, cutting mills, diverse types of granulating systems are part of today's delivery program.

Today in the year 2021 SIKOPLAST Recycling Technology started its new orientation with the move to the new sales and service office in Troisdorf.
