Waste Coffee Grounds Offer New Source of Biodiesel

Posted by timothy on from the as-if-you-needed-another-reason dept.

Julie188 writes "Researchers in Nevada are reporting that waste coffee grounds can provide a cheap, abundant, and environmentally friendly source of biodiesel fuel for powering cars and trucks. Their study has been published online in the Journal of Agricultural and Food Chemistry. Growers produce more than 16 billion pounds of coffee around the world each year. Scientists estimate that spent coffee grounds can potentially add 340 million gallons of biodiesel to the world's fuel supply."
