Has anyone done it? I have been in business for 3 years now, and every season it seems more and more people demand a business that is green. I don't mind either. I agree that working with nature is much better than working against her. I think over the next several years, people are going to demand more and more a landscape company who is green. So has anyone run a truck on veggie oil here? If so, was it easy to build relationships to get the oil? Did you have to pay for it? How big of a mess is the filtering process? Any other details I should know? Would love to get some input! Thanks in advance.
