I finally got the perfect car and have the perfect WVO system to go in it but am having problems locating a good source. I have called around some local places and the word I get is that they (the buisness) has a contract with a waste company who picks up all thier waste. This waste collection company seems to have the market cornered- they in turn give the grease to a growing bio-deisel producing company here in Oregon. Any good ideas for how I should approach a potential donor? Anyone else run into this problem before? I hate to get everything in place only to find out I cant get oil because some other company has a monopoly.
