Designer, Engineer, Consultant, Author and General Manager of a company for dry toilets
BERGER BIOTECHNIK GmbH
"shit is earth"
I like to develop low-cost solutions and innovative designs for sanitation and shelters, which are both attractive and practical. Dry sanitation should be a standard in developed countries to be a model for all others. I try to support this, being involved in inventing, producing and engineering waterless systems in many projects in Germany and foreign countries since 25 years. I am also publisher and main author of a German book on composting toilets, which is also published in Russian and hopefully in English language. My first publication "Shit is earth" was published in 1977, reporting on histoy of dry sanitation and designing a dry toilet.
