I am about to purchase an oil press and a biodiesel dry-wash production unit that will produce nominally 450 gallons per day. We are in the process of collecting waste vegetable oils but would like to expand production by utilizing the seed press and persuading a local farmer or two into producing several acres of rapeseed as a winter cover crop and exchange seed for an on-going supply of fuel to run their farms. This would have been a much better idea last year, before the $1 a gallon tax credit for bio-diesel production expired but I initially intend to produce enough fuel to operate our business (around 1200-1500 gallons per week) with recycled vegetable oil, if we can locate this much, and expand into virgin oil production by barter from area farmers. I am looking for productive means of disposing of the waste product (glycerin). I understand that it is biodegradable and can be composted but think maybe soap production might be a better alternative and soap, in many forms, has value as a trade good. The next waste product would be the left-over seed cake, once we begin pressing oil. One of our group raises beef cattle and this will be utilized as a feed supplement and traded for beef on the hook. I am about to enlist the aid of our local agricultural extension agent in assesing the viability of this project.
