In chemical recycling, KraussMaffei Extrusion is focusing on key technologies: high-performance extruders for processing material streams - for example, to produce pyrolysis oils - efficiently implement crucial process steps such as dewatering, degassing and the removal of impurities. Pressures of up to 200 bar and the retractable UltraGlide system with easy-to-maintain screws enable customized solutions for demanding recycling applications.

K 2025: PET Recycling à la KraussMaffei
More output, less investment - optimized recycling processes
From bottle-to-bottle PET recycling to material preparation for chemical processes - as a driver of innovation in the circular economy, KraussMaffei Extrusion offers pioneering solutions for all forms of recycling.In the PET recycling sector, KraussMaffei Extrusion is presenting a high-performance twin-screw system based on the BluePower series for throughputs of up to 12 tons per hour. The concept responds to the increasing demand for higher output and more energy- and cost-efficient processing. Compared to conventional twin-screw systems, energy consumption can be reduced by up to 20%. The systems are compatible with standard SSP units and produce food-grade rPET.

KraussMaffei Extrusion has also refined its EdelweissTechnology for processing recyclates more efficiently – even with fluctuating material properties. The focus is clearly on process optimization and cost efficiency. The twin-screw extruder covers all process steps: degassing, filtering and compounding. “This integrated setup can lower investment costs by up to 25%,” says Dr. Thomas Unger.
More efficient research, more economical production: ZE BluePower in a new design
Whether for research or daily production - the new generation of the ZE BluePower twin-screw extruders offers clear advantages. The new ZE 28 BluePower scores with improved operation, greater energy efficiency and digital networking via ppC (pioneer processControl). The larger ZE 42-80 series has also been comprehensively redesigned - with a focus on simple maintenance, digital interfaces and an optimized modular system. "For our customers, this means a better price-performance ratio and shorter delivery times - real advantages in day-to-day operations," says Dr. Thomas Unger.
