Greenstock LLC seeks to develop biodiesel feedstocks within California for California Biodiesel Producers. We promote a sustainable biodiesel industry that sources multiple feedstocks from within each producers local area (within 100 miles). We encourage new producers to install multi-feedstock processors so that they have the flexibility and agility to use the cheapest feedstock available at any time.

Starting in Nov 2007, Greenstock will be collecting waste fryer oil in Santa Clara and San Mateo Counties to supply local biodiesel producers. Click on the Greenstock link to see what services we provide.
