Coop Handbook for Working

Our friends at the National Center for Appropriate Technology helped us put together this Energy Use Report during a visit in early 2007. Thanks NCAT!


Piedmont Biofuels is a worker and member owned cooperative. Our mission is to lead the grassroots sustainability movement in North Carolina by using and encouraging the use of clean, renewable biofuels.We are involved in a wide variety of undertakings in support of this mission:

  • We provide pure biodiesel (B100) to the community.
  • We maintain a top quality biodiesel plant where worker-members can make their own fuel from waste vegetable oil which we collect locally.
  • We have a USDA Registered Research Farm where we do oilseed crop research and run a market garden for wholesale and our local farmer’s market.
  • We have an elaborate glycerin vermi-composting project.
  • We do education and outreach on both biodiesel and engine modifications that enable people to use straight vegetable oil (SVO) as fuel.
  • We lobby the North Carolina legislature, as well as our national representatives, on behalf of biodiesel and alternative fuels. Check out our Policy Page.
  • We have an intern program that allows people to live on site and learn about all facets of our operations.

Member Biographies

Piedmont Biofuels is a loose confederation of individuals and entities. Here are the bios of some of the people you might bump into around the place if you dropped in unannounced.

Andy McMahan

Andy is a frisbee fanatic. When he is not dominating ultimate games he is designing disc golf courses. Had he come from California he would surely have been a surfer. But he came from Guilford County, where he pioneered a biofuels class. Now he works at Central Carolina Community College, where he is working on installing a disc golf course, and running both the biofuels program and developing the green building curriculum.

Rachel Hoff

Rachel is our latest board member. On the back of her TDI is a bumpersticker which talks about how biodiesel is “sexy.” She is also known for the pecan trees which grace her land. Whenever you see people shelling pecans in the front yard of the coop–chances are they came from Rachel’s place.

Jurgen Henn

Jurgen is the eyes and ears of Durham, who sits in on coop board meetings when he can. He’s a homebrewer, with a wide sweeping blog who keeps us in touch with the Durham scene.

David Thorton

David is the design-build king. He buys a lot of tanks, plumbs a lot of tanks, and is a competent wheeler-dealer. What he buys for a dollar, he sells for a dollar, but he is intent that he will make it up in volume. He’s also run fuel making at the coop, lends a hand teaching biofuels down at the college, and is the one who introduced frisbee golf to the folks on the other side of the creek.

Evan Ashworth

University of Chicago survivor from Trenton, N.J. Thrilled to be living his lifelong dream of playing with cranes and driving a big yellow truck. Evan runs the fuel distribution business at Industrial. Every time he comes back from delivering bulk fuel to farmers he is convinced on the need to arial spray toxins to increase farm productivity. We tend to coax him back into the “sustainability track.” When he is not driving around in his mirrored sunglasses, he is leading tours at the coop, or clubbing big grants for stuff.

Rachel Burton
