Leading Technologies for Polymer Processing and Recycling
In addition to unique technologies, systems and components for plastics processing, Gneuss also offers complete turnkey solutions for the production of high quality sheet, strapping, fiber and pellets.
Since its founding in 1983, Gneuss has grown to become a worldwide technology leader for the extrusion of polymers and the reprocessing of all kinds of polymers.
Based in Bad Oeynhausen, Germany, Gneuss is committed to the expectations of products “made in Germany” while serving our customers world-wide.
A technology center for processing technical trials and development work is available at Gneuss´ headquarters in Bad Oeynhausen. Additional pilot lines are available for trials at our subsidiary, Gneuss Inc. in the USA and at our cooperation partner, SysTech in Japan.
Polymer and extrusion technologies
Gneuss sheet extrusion lines are flexible and can be operated with recycled material and / or virgin material. Sheet made from recycled material is suitable for food contact applications.
With Gneuss PET strapping lines, polyester strapping tape with a high tensile strength can be manufactured from 100 % recycled material.
Fiber & Filaments
Undried PET post-consumer bottle flakes or production waste with different viscosities can be processed into high-quality fibers.
Degassing & Decontamination of PS / PE / PP / PA
The Gneuss MRS extrusion concept is used in different applications for devolatilization and decontamination of polymers.
News & Informations
MRSjump PET Recycling
The new Gneuss MRSjump offers both decontamination performance to food contact levels and the ability to maintain and control the IV of the PET in one single extrusion processing step. There is no need to treat the material prior to extrusion and no need for an additional melt or solid phase IV boosting process in addition to extrusion.More
New size 110 for Rotary Filtration Systems
Gneuss Filtration Technology is introducing an additional size across its line of Rotary Filtration Systems. The models RSFgenius, SFXmagnus, SFneos and CSFprimus are now available in a size 110, which offers almost 20 % more active screen area than the size 90 for each model, 46 to 62 square inches.More
Efficiency Improvements through Retrofitting
Spanish PET bottle-to-bottle recycler Nososplas is achieving significant efficiency improvements by replacing its melt filter with the Gneuss RSFgenius back flushing filter. Nosoplas decided in favour of the Gneuss Rotary Filtration System due to the high efficiency and the fast return on investment which it offers.More
