It was the process used in the early gasworks until they were superseded by the use of natural gas whose formula is more akin to the product of an anaerobic digester, being mainly methane.
Here ends today's chemistry lesson!

I have an anaerobic digester at the moment, she is sat on the settee, and I can confirm that the gas given off could power a small village
