Check out our newly published book, How to Build a Solar CITIES IBC Tank Biodigester. This book is the first in “A Biogas Education Series” and is a step-by-step illustrated manual on how to build one type of biodigester, the IBC tank biodigester. This type of biodigester uses an IBC tank, or tote tank, and PVC plumbing parts commonly available in the U.S. and Canada. This design is based on the work of Thomas Henry Culhane, founder of Solar CITIES. For further guidance, visit our Facebook group and join the conversation. Be on the lookout for more in this series!
