Gneuss, a family-owned company based in Bad Oeynhausen, Germany, has been shortlisted for the Plastics Recycling Awards 2022 in the category of Recycling Machinery Innovation with its unique MRSjump extrusion technology.

The MRSjump is a new extruder which uses the operating principle of the Gneuss MRS technology however with a vastly expanded devolatilising capacity.

Originally aimed at post-consumer PET recycling, the MRSjump extruder offers PET processors not only unparalleled decontamination performance but also the possibility of retaining or even lifting the intrinsic viscosity of the material without the need for any heat treatment of the material, either before or after extrusion.

The phenomenal devolatilisation performance of the MRSjump extruder offers massive advantages for post-consumer polymer recycling generally, especially for recycling polymers such as polyolefins and PS for food contact applications (to FDA and EFSA) where decontamination of the polymer is important. As in the case of PET, due to the decontamination performance of the extruder, additional, energy intensive heat treatment of the material can be avoided.

This performance was made possible by enlarging the MRS multiple screw design. Both the surface area of the polymer melt under vacuum and the area exchange rate have been drastically increased.

As a result, post-consumer polymers can be recycled energy efficiently in one step with the MRSjump extruder to high quality and high value food contact materials.
