How to Build a Biogas Digester: Intro

The purpose of the information presented here and in the few pages listed immediately above is to offer you a general understanding about how to build various kinds of small biogas digesters. There are plenty of sites around that offer information that could be similarly described— several are linked from these pages— but here you are likely to find information that few other sites offer, and which will help you decide among the designs described on the web. Read on. See if it’s not so…

Be clear however, this information will not in some absolute sense be “complete”, for many reasons, but two main ones.

  • First, the critical things you need to know about biogas are that you have to keep the organic stuff wet, warm, and pH balanced. Beyond that, we’re not going to explain 100% of everything you may need to know about biogas to make the best use of any digester, large or small, and of course that includes those discussed in these pages. (There’s really too much information about biogas to fit on a few little pages, and gee whiz, if you’re all that interested in practical biogas, you should probably buy The Complete Biogas Handbook— see that book cover to the right?— which after all, hello, is the point of this site.)
  • The second reason is that our intention is not to offer information at the level of blueprints and exacting engineering specifications, but rather to offer you a solid overview, and point you to what we consider to be the best free resources on the web (use the links provided!), which can then get you further down the road…
