methane from a septic tank

I do not know if a diesel engine can be converted to run on methane or not. I do know that gasoline engines can.
It is not dissimilar to conversion for using Propane.
I think the downside to using methane recovered from animal waste is collection, purification, and compression. While it is possible to do these things doing them on anything less than a large comercial scale is not practical. It may not even be economically practical on that scale, I say that because I believe someone would be doing it already if it was practical.

The regonal land fill near where I live recovers the methane generated by the rotting garbage and compresses it for later use. There are 6 large dairys near here and they all are building metane digesters fed by the cow poop and use it to fire their boilers.
It can also work in a small scale too. In 1979 when I lived in Ark, we used a 55 gallon drum digester to fuel our gas hot water tank, and gas cook stove. We used grass clippings, moldy hay, etc.
There are lots of people using it to stay "off-grid" today!

ok guys by now you should know how hardheaded i am. i need better answer than those.
lets say we modifed a septic tank that could collect all the methane and we had alcohol gas trap that we could monitor it and we added stuff to the tank such as wilted cabbage from super market trash, beans, sawdust, leaves what ever so we could get this thing realy brewing
remember this thing will be brewing 24 7
just think about the last time you ate cabbage or beans now that just a small portion and maybe half of what its capable of.
and we had a GO metro converted to run methane.
how many miles do you think we could go on a week worth of methane?

As for pullonthis21, you would need a pressure tank to store the methane in, and a compressor to compress it. The tank is really not the problem, the compressor able to pick the gas up in ounces or even at a vacuum rated for Nat Gas is going to cost you more than 2 brand new PowerStroke Diesel trucks.

Compression is the issue, that's for sure.
I deal with natural gas pipelines every day at work, and the smallest compressor I've ever heard of costs around $150,000 for 90 hp. There must be ones smaller than that, but it's starting to be a pretty specialty item. Certainly that's oversized for the home septic system you are talking about. you would need less than a single hp I would imagine.
I have heard a little about people using "microturbines" as electrical generators. Could be another alternative to burning it in your truck.
Our company burns natural gas in some old ford 400 engines to make electricity in one location.

Couldn't find any specifics on the pump but I'd guess reciprocating.
found some interesting reads.

I thought methane had to be cryogenically cooled to -260F to liquify it. Those home pumps do 3600 PSI and they still call it a CNG system, as opposed to LNG. LNG tanks are double walled, super insulated, with a vacuum separating the two walls - to keep the product cold... same as liquid hydrogen fuel cells.
