Single screw extruder with multiple screw section for high-efficient degassing and decontamination of contaminated polymers.
Continuous, pressure and process constant melt filter for the cleaning of all kind of polymer melts.
High-precision and robust sensors for pressure and temperature measurement, even for difficult and demanding process conditions.
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
The JUMP reactor reprocesses industrial and post-consumer PET waste to high value products.
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
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
Trouble-free melt filtration
If in-house production waste and heavily contaminated post-consumer waste are added to the production process, foreign particles of various sizes and quantities are introduced into the melt flow. These must be efficiently filtered out to ensure consistent product quality. Thereby the production process must not be disturbed.More
Tray to Tray Recycling
If a circular economy is to be realised, it will be necessary to consistently recycle post-consumer thermoformed PET trays back into PET trays. The recycling of regrind from post-consumer PET trays to new sheet for PET trays presents challenges for the recycling process. For this demanding process, Gneuss has developed the innovative MRSjump Extruder.More
