About Us

www.Greengreasemonkey.com got its start in April of 2004. Since then, we have converted a wide variety of vehicles to run on waste vegetable oil (WVO). We have also set up several small-scale biodiesel processors, and brewed hundreds of gallons of biodiesel. We are based in Boston, Massachusetts, but have customers around the country and always like to hear from folks in other areas. If you’re in the neighborhood, feel free to stop in!

We are constantly spreading the “grease gospel,” and will take any opportunity to speak at gatherings large and small about the technology and our work. If you have a science fair, Earth Day event, or community get-together where we can come and exhibit our cars, we will be happy to do so. We particularly like to speak to young people, and have done several speaking engagements for schools and youth groups.
