Sihanoukville in 2007 a non-profit named Planet Biodiesel Outreach Cambodia started a small scale biodiesel production plant. The biodiesel was used to operate their school bus and to provide fuel for their travel company. Their idea was to operate an environmentally friendly tour company and to use the proceeds to run a school for impoverished Cambodian children and provide food, clothing, education, school supplies and transportation free of charge. They ran their school bus on 100% biodiesel that was produced from waste vegetable oil. Planet Biodiesel Outreach Cambodia shut down in 2008 due to lack of donor funding and the inability to raise enough revenue from their tour company.
