Testing and evaluation of biomass conversion and circular economy processes
We at GNS are your partner when it comes to process engineering assessments, tests and reports - especially for new processes for biomass conversion, residual and waste utilization and valuable material recovery. We prepare independent reports and technical due diligence for investment projects. In addition, we carry out ecological, environmental and economic assessments of processes, products, residual materials, waste and emissions.
