DIY Biogas: Make and Use Your Own Renewable Natural Gas

The book contains all the relevant information for starting biogas. Definitely worth the price. It's not too big and not too small. If you are a beginner buy this book. Other beginner biogas books lack as much information as this one.

This was an informative book, but the first time I was reading it the pages fell out.

A good book to start down with if you are interested in making bio gas.

excellent work
