About us

Gneuss Kunststofftechnik GmbH is one of the technology leaders on the world market in the sector of plastics processing. Since its foundation in 1983, Gneuss has made a name for itself as a supplier of innovative solutions for the plastics processing industry.

The company’s business is divided into three sectors: Filtration Technology: Development and production of fully-automatic, pressure-constant and process-constant filtration systems / screen changers for the filtration of plastic melts. Processing Technology: Engineering/manufacture of extruders and sales of extrusion lines for further processing of PET recycling and polymer material.

At the beginning of 2011, the Gneuss PET recycling process received a “Letter of Non-Objection” (LNO) by the US American Food and Drug Administration (FDA), for the use of up to 100 % recycled material. Measurement Technology: Production of measurement and control technology, e.g. pressure transducers and temperature sensors.

Products and services

Gneuss has been at the forefront of polymer recycling technology for over 30 years now and offers a range of innovative solutions for the processing and recycling of polymers. Gneuss´ systems are optimised for the challenges of PET recycling. They are perfectly harmonised with one another and their modular design can be configured flexibly. The Gneuss-Processing-Unit (GPU), consisting of the unique Gneuss MRS Extruder, Rotary Filtration Systems and Online Viscometer represent the heart of the Gneuss recycling systems. With the MRS Multi Rotation System, Gneuss provides a processing system, which can handle a wide range of input materials with different qualities and properties. It can process 100 % recycled material without pre-drying or crystallising. Polymer purification takes place not only in the MRS extruder but also in the Gneuss Rotary Filtration Systems which ensure a purified polymer melt, without foreign particles or specks.

Gneuss Processing Unit (GPU) with polyreactor Jump

The GPU has proven itself on the reprocessing of bulky PET waste such as post-consumer bottle flake and industrial waste from fibre and film manufacture. This Gneuss Processing Unit consists of the Gneuss MRS extruder with its unmatched devolatilisation and decontamination performance together with the highly-efficient Gneuss Rotary Disc melt filtration systems and the Gneuss Online Viscometer for intelligent dynamic viscosity control, monitoring and logging.

News & Innovations

Gneuss Measurement Technology Products
As a machinery manufacturer, Gneuss has the manufacturing capabilities to realize even unusual sensor requirements. The lean manufacturing structure at Gneuss makes this possible with shortest delivery times. Gneuss sensors are available to match regional or application – specific requirements such as Atex, Hart Communication or EAC.
Gneuss Rotary Filtration Systems
All models have been completely revised in the last years. Modifications to the screen changer housings permit operation on a wider range of applications at higher pressures, whilst offering enlarged active filtration areas. Components and modules have been commonised in order to offer shorter delivery lead times and lower costs.
Gneuss MRS Extruder
Although originally developed specifically for PET, the MRS is now also running in polyolefin and nylon applications, and being tested on a range of other materials and applications. Thanks to the patented combination of single screw extruder with a multiple screw section, the extruder is very sturdy and particularly well suited for recycling applications.
