Product innovation Corema

When it comes to materials and quantities Corema systems are available for both smaller amounts of 300 kg/h and large amounts of up to 4 t/h. And the same applies to the raw materials to be processed – Corema is suitable for an extremely broad spectrum of material. The large, patented Erema cutter/compactor is a great opportunity in that you can use this system for a wide variety of recycling jobs and applications according to the design.

CEO Manfred Hackl explains with pride: "We are of the opinion that Corema is the ideal system not only to process inexpensive mixed fractions such as PET/PE with additives, but also to produce a compound with 20% talcum out of PP nonwoven waste, for example.” As well as being used in the electrical and construction industry, PP/talcum compounds are used mainly for white household goods and in the automotive industry. The amounts of PP recyclate used in these applications are still relatively small, yet the potential is big. With Corema you can make economic use of precisely this potential.

A pilot Corema system with an output of 400 kg/h is already in use at a customer's plant near to the company's headquarters and Erema operates a system of its own at the headquarters with 600 kg/h output.

Dutch company Rodepa Plastics B.V is the best example of the huge interest in Corema. This company has been operating two Erema recycling systems for a number of years and has noted increasing customer demand for filled recyclates over a longer period. Mark Langenhof of Rodepa explains: "This is why we looked very closely into compounding and had a look at what machines were available on the market. When we heard that Erema covers this topic with their own product line we contacted them straight away." And the result: Rodepa is now moving into the compounding business with Corema.

For Mark Langenhof the logical configuration of the system was convincing: "The recycled material is processed and filtered in the robust and proven cutter/compactor single-screw system. The clean melt then moves directly to the twin-screw unit which is available for a wide variety of compounding tasks.

All in all you can expect outstanding energy efficiency from this process. Besides this it is also important for us to have a strong partner by our side, especially in this field. Thanks to its excellent after-sales service Erema is second to none and has been for many years."

At the moment Rodepa mainly uses production PP for injection moulding applications – also in the automotive sector – and LDPE for film applications. In the future, however, the company intends to process more post-consumer material. Mark Langenhof on the future strategy: "New opportunities, new markets, new challenges".

Ever since it was founded Erema has always invested in research and design to be able to react to the demands of its customers at all times and is committed to solutions and close collaboration with customers. The new product Corema confirms once again the ongoing development of the company.
