Gneuss, a German manufacturer of machinery and components for plastics recycling and processing, will present solutions at Plastindia 2026 to help processors operate more economically. These solutions will enable processors to achieve higher process stability, reduced energy consumption, fewer production stops, and consistently high product quality.
Key topics include OMNI recycling systems, MRS extrusion technology and Gneuss rotary filtration systems, including the RSFgenius series. These technologies support processors in running stable operations even with challenging material qualities, reducing both energy and material consumption and upgrading existing lines efficiently – in recycling as well as in conventional extrusion and compounding.
OMNI recycling systems – high-quality recyclates with high process efficiency
Recyclate requirements continue to rise, while the properties of incoming material streams often fluctuate significantly. OMNI recycling systems are designed to reliably handle these variations and to produce high-quality recyclates in an economical way. Depending on the application, a wide range of polymer streams can be processed, including PET, polyolefins and styrenics.
A major focus is the production of high-quality recyclates for applications with high purity requirements, including solutions for food contact applications, based on corresponding regulatory assessments in the United States and Europe. Process stability, reproducible product quality and low operating costs are key targets, supported in particular by efficient devolatilization and continuous melt filtration during operation.
MRS extrusion – efficient devolatilization as the key to quality, throughput and energy savings
A central element of Gneuss technology is MRS extrusion. It combines proven single-screw technology with a dedicated multi-screw section that significantly increases the melt surface area under vacuum. As a result, volatiles, moisture and odor-forming components can be removed very efficiently.
For processors, this means improved and more consistent product quality, reduced odor, fewer gels or optical defects, and a more robust process even with difficult materials. At the same time, energy and equipment requirements can be reduced because in many applications no complex pre-drying is required. This lowers energy costs, simplifies line design and reduces potential sources of operational errors.
Rotary filtration systems – continuous filtration for stable processes
Stable melt pressure and consistent filtration are essential for uniform product quality and economical operation. Gneuss rotary filtration systems enable continuous melt filtration without production interruptions – even with strongly varying contamination levels.
The RSFgenius series in particular combines constant-pressure filtration with efficient backflushing for automatic self-cleaning. This helps minimize downtime, reduce operator effort and screen change requirements, and limit material losses. Users benefit from a more stable production process, lower scrap rates and higher overall line efficiency – both in recycling and in demanding extrusion applications.
Retrofit and process optimization – efficiency improvements without full reinvestment
Another focus is on retrofit and optimization projects. In many cases, significant improvements can already be achieved by upgrading existing lines with modern melt filtration and extrusion technology – for example through increased process stability, reduced downtime, improved output and lower operating costs. This enables efficiency gains without the need for a complete new line investment.
