Project Experience

Premium flooring with PCR

The Classen Group produces premium floor coverings made of polypropylene under the brand name "Ceramin". The recycled content is up to 60%. The finished tiles are PVC-free and can thus be disposed of in an environmentally friendly manner at the end of their life cycle. The high proportion of recycled material with changing material properties places high demands on the production technology.

Project partner Leistritz

As a partner in process development, but also as a project partner for the realization of a new production line, Leistritz contributed to the cost-effective manufacture of the sustainable product and to almost doubling the output of production from 5 t to 9 t per hour. For the production of the flooring panels, Leistritz supplied two ZSE MAXX twin-screw extruders and designed, built and commissioned the entire production line. The processing procedure was designed in such a way that particularly few rejects are produced.

We are experiencing great interest in our expertise in recyclate processing and are constantly opening up new areas of interest as a result.

Floors have to be tough.

Especially in public areas, they are subjected to extreme loads and must last as long as possible. The boards are manufactured without PVC, chlorine or plasticizers and can be recycled at the end of their life cycle.The material combination for the surfacing is a completely new development. It is based on mineral materials and PP recyclate. The use of recyclates in high-quality applications with specific requirements on plant technology is clearly a trend.
