Your specialist for natural and residual material utilization for over 25 years

Reduce, reuse, recycle – we value sustainability!

We at GNS have specialized in the topics of circular economy, environmental technology and the use of biomass. The aim of our work is to develop technologies for our customers to reduce emissions, recycle waste and recover valuable materials. In our laboratory and technical center, we examine a wide variety of natural and residual materials from our customers at home and abroad. We examine all treatment steps in theory and practice and derive new process engineering solutions from them.

Processes and process combinations often involve great risks for the investor. Extensive expertise is essential, especially at the level of process functionality. This is the only way investments worth millions can actually generate the desired return. Our team has decades of experience in the field of environmental and process engineering.

We prepare independent reports, material and energy balances and oversee plant optimization on site. Many investors, planners and plant operators have already benefited from the knowledge of our process chemists and process engineers.

We carefully examine every procedure down to the smallest detail. This means you have greater investment security and do not have to worry about unpleasant surprises.

Would you like to find out more about our processes for the use and processing of biomass and waste, carbon footprints and the recovery of valuable materials? Then we look forward to hearing from you!
