Question

What are the inputs for biogas productions?

Answer 1

Digesters typically can accept any biodegradable material, with the level of putrescibility (the degree to which it decomposes) being the key factor in biogas yield. While sewage and different types of manure are most common, they yield less than non-woody organic waste (grass and plants) which have not already had the energy content taken out. A wetter feedstock with a 20-30:1 Carbon:Nitrogen ratio is most efficient as it moves through standard pumps easier and improves biogas yield.
