News & Informations

Expansion of Gneuss GmbH’s management team

The Gneuss company has appointed Kai Gottwald to the management board. Kai Gottwald, who has been with the company for 16 years, joins the family duo of Dr. Stephan Gneuss and his brother Daniel Gneuss at the top of the company.

Recycling of LDPE / LLDPE Film

In an extrusion line for processing post-industrial waste film from LDPE/LLDPE, the filtration provided was unable to remove all impurities from the melt. The Spanish company Llorens uses an RSFgenius melt filter for this purpose.

PET Waste to High Quality Fibers

For use in its technical centre, Korea Textile Development Institute KTDI decided to buy a Gneuss MRS extrusion system for processing postconsumer PET waste for yarn manufacture. For this process, the MRS extruder offers the opportunity to adjust the viscosity of the PET by means of the vacuum.
