Can a Septic Tank Be Turned Into Biogas Generator?

I have always wondered why a septic tank isn’t by default a biogas generator. I did some research today and the answer didn’t turn out to be so simple, apparently there are certain things that are needed to be added to a septic tank to turn it into a biogas generator.

First you can’t have chemicals like detergents going into the biogas generator.

Second, you need heat for more efficiency.

Third you need airtight tanks.

There are 4 stages of reactions that take place in a biogas generator only two of them happen in a septic. But the answer to our question in the title is: Yes, with a few tweaks you can turn a septic into biogas generator. But, taking the efficiency factor, is it worth it?
