The specialist in paper recycling, from start to finish.

Custom-made systems construction, from non-stop sorting systems to conveyor and feeder technology, as well as metal and steel work in line with individual customer requirements.

Grumbach und Petermann GmbH (GUP) is a traditional company which implements innovative, individual technological systems for paper recycling. The family business was founded back in 1989 by Udo Grumbach and Hermann Petermann, who gave the company its name. The company specialises in the entire paper recycling process from start to finish, conducting the majority of the work with our very own machinery, produced in-house: when it comes to full systems construction, sophisticated conveyor and feeder technology, innovative grippers through to metal and steel work and even our mechanical non-stop sorting system PaperSpike®, GUP is the go-to company for bespoke solutions.
