A small-scale biodigester suitable for a home, small farm or small food enterprise will cost you between $500-3,000, depending on many variables (how big the system is, if you want to use it year round, if you buy a prefab system or make one yourself, etc.). Medium- and large-scale systems are more expensive. There is a reliable company that makes prefab systems (https://www.homebiogas.com/). They are based in Israel/Palestine and ship within 2 to 3 weeks at a reasonable price. The carbon footprint of shipping is one reason we are exploring local production.
