I will continue the step-by-step introduction to home scale biogas for those interested in learning how to make it with my next post. In the meantime, I thought it might be helpful to mix things up with what I call my Biogas All-Stars series. These are posts where I will highlight one of my colleagues in the international biogas community and let them to answer questions about their projects in their own words.

I believe MOTHER EARTH NEWS readers will find this series useful, as it will offer examples of different types of regionally-appropriate digester designs. These All-stars inspire us all with their resourcefulness and dedication, working with locally available materials in often inhospitable – sometimes even dangerous – conditions to build biogas digesters to transform the lives of people who need it most. The Biogas All-Stars do not appear in any order. I would like to begin with one of the most likeable people I have ever met, Marcello Ambrosio, with the Studio Ambrosio Agricultural Consulting, from Italy.

Marcello (pronounced March-ello) and I met in New York City during a conference for Solar CITIES, an international non-profit biogas education and training organization we both belong to. He is a big fan of Western movies, and once worked as a cowboy in Wyoming during a visit to the U.S. When it comes to building biogas digesters, however, he is definitely the Lone Ranger. Usually working by himself, he has single-handedly built digesters as large as 100 cubic meters (26,000 gallons).
