About Me

I am an environmental engineer with a passion for toilets in all shapes and colors. My research focus at Eawag is on resource recovery from urine.

With the Blue Diversion Autarky Toilet, Eawag has developed a decentralized off-grid wastewater treatment concept. Based on source separation, the system uses three modules to treat urine, feces and water separately.

Within this project I am responsible for the urine treatment. Main tasks include technology development, laboratory experiments, coordination and performing of field tests in Switzerland and South Africa, as well as supervision of interns, students and scientific assistants.

Projects

We develop reactors for the separate treatment of urine, feces and water directly in the toilet.
