Christoph Fühner is a biologist at the Helmholtz Centre for Environmental Research in Leipzig, Germany. He uses his long-term experience in the ecophysiology and soil science of plant mineral nutrition for the development of so-called "sewchar systems". His concept integrates benefits of thermochemical technologies in wastewater treatment and the reuse of carbonized materials as soil amendments to establish sustainable resource management in sanitation systems.
