About us

Gneuss is a supplier of innovative solutions for the extrusion and recycling industry. Its patended MRS extruder offers new possibilities with regard to the efficient devolatilisation and extrusion of hygroscopic polymer melts like polyester, nylon or polyolefins. Combining these with Gneuss process-constant and fully automatic screen changers and high-quality pressure and temperature sensors allows very efficient processing of highly contaminated materials. Gneuss offers with the new series of OMNI Recycling Machines recycling lines for losed loop recycling of PET, PS and polyolefin post-consumer reclaim and for fiber recycling.

New OMNI Recycling Machines for closed loop recycling of PET, PS and polyolefin post-consumer reclaim

Gneuss’ MRS Extrusion Technology has proven itself as an alternative for the reprocessing of contaminated materials like polyester, polystyrene, polypropylene or polyethylenes. In combination with the highly efficient Gneuss Rotary Filtration Systems and optimized vacuum technology, customizable recycling lines tailor-made for a specific material can be engineered. Several Letters of Non Objection (LNOs) from the FDA, EFSA conformity and local approvals confirm the decontamination efficiency of the technology.

MRS Extruder

The MRS extruder is based on conventional single screw technology but is equipped with a multiple screw section for devolatilization. It enables very efficient and gentle decontamination of PET, whilst achieving the requirements for direct food contact standards. The MRS extruder permits the processing of R-PET directly into high quality end products such as packaging sheet, strapping tape or filaments without pre-drying by using a simple and rugged vacuum system.

MRSjump Extruder

The new MRSjump has a longer, modified version of the Multi Rotation Section, which ensures both a longer residence time of the material and more surface area exchange under vacuum. The longer Multi Rotation Section, coupled with a powerful vacuum system operating at 1 mbar, can be used to boost the viscosity of R-PET and to hold it at a stable level in spite of variations in the input material. Therefore, there is no need for any liquid phase (LSP) or solid state polymerization (SSP).

Rotary Filtration System RSFgenius

These continuous rotary filtration systems are characterized by a filter disk on which the screen cavities are located in a ring pattern. Screens can be changed on the part of the filter disk that is not active in the melt channel, while the production process continues to run without any interruptions or disturbances. Gneuss’ top model, the RSFgenius, operates with an integrated back-flushing system offering self-cleaning for very demanding applications and highest quality requirements.
