Gneuss showcases solutions for stable recycling and efficient extrusion at CHINAPLAS 2026. Key highlights include OMNI recycling systems, MRS extrusion technology, and the company's rotary filtration systems.

These technologies enable processors to maintain stable operations, even with challenging material qualities. They also help reduce energy and material consumption, while efficiently upgrading existing lines in both recycling and conventional extrusion and compounding.

OMNI recycling systems

OMNI recycling systems are specifically designed to reliably handle incoming material streams with fluctuating properties while producing high-quality recyclates in an economical manner. Depending on the application, they can process a wide range of polymer streams, including PET, polyolefins, and styrenics.

With features such as efficient devolatilization and continuous melt filtration during operation, these recycling systems ensure process stability, reproducible product quality, and low operating costs.

A primary focus is the production of high-quality recyclates for applications with strict purity requirements, including solutions for food contact applications, supported by the necessary regulatory assessments in the United States and Europe.

MRS extrusion

MRS extrusion technology combines proven single-screw technology with a specialized multi-screw section that significantly increases the melt surface area under vacuum. This design allows for the efficient removal of volatiles, moisture, and odor-forming components.

Even when processing challenging materials, this extrusion technology enhances product quality by producing more consistent results with reduced odors, fewer gels or optical defects, and a more robust process.

Moreover, energy and equipment requirements can be minimized, as many applications do not require complex pre-drying. This leads to lower energy costs, simplified line design, and a reduction in potential sources of operational errors.

Rotary filtration systems

Gneuss rotary filtration systems facilitate continuous melt filtration without production interruptions, even in the presence of highly variable contamination levels.

The RSFgenius series, in particular, combines constant-pressure filtration with efficient backflushing for automatic self-cleaning. This design minimizes downtime, reduces operator involvement and the need for screen changes, and limits material losses.

As a result, users benefit from a more stable production process, lower scrap rates, and higher overall line efficiency in both recycling and demanding extrusion applications.

Retrofit and process optimization

Another focus is on retrofit and optimization projects. In many cases, significant improvements can be achieved by upgrading existing lines with modern melt filtration and extrusion technology. These upgrades often lead to increased process stability, reduced downtime, improved output, and lower operating costs. As a result, customers can realize efficiency gains without the need for a complete new line investment.
