One of the things we encountered when we were operating was the variable price of methanol - as our production went up, the price of the methanol went up. Strangely, we had problems getting lye - I actually had to send a letter to the DEA defining what we were doing even though lye was not watched. the wors though was the waste stream - soapy water and glycerin - there are stoves that burn glycerin but it would have had to be refined. We finally managed a contract with ranchers. It seems that there are a hell of a lot of waste stream problems solved by..... feeding it to the cattle. We couldn't feed them soap though so we had a settling pond and skimmed the crap off the top. The water still didn't qualify as grey but we figured out a way to recycle it.
Interestingly, our profit hinged on the government and their 50 cent per gallon incentive but I saw a great potential in carbon offsets that we explored with the Chicago carbon exchange. Of course the big ag folks got a dollar because they were using pure soy as feedstock. That was sort of backwards as we were the ones doing the recycling but they were the ones with the lobby. When we left the business do to zoning problems we left a huge hole in the local market that was never filled. If I had the resources I'd do it again.
you should look into the local farmers' biodiesel co-ops. they make lots of that shit for ag equipment. they are always lookin for a way to cut costs and improve production. too many old diesel tractors cant run diesel #2 without blowing up so biodiesel is the oly choice for a lot of smaller farmers.
