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."

    What they should do is offer a recycling program for the used coffee grounds, and take the money made from that to subsidize current fuel prices. Then eventually wean people off that to alternative fuels.

  2. I did that already. by RustinHWright · · Score: 1, Troll

    Take a look again at my pricing. I give fifty cents a pound as the net value for oil. Which is a damned conservative valuation even including those costs. Think of what oil sells for now. Dude, I'm a former logistics and process consultant; I'm way ahead of you.

    Oh, and for future reference, comedy shows, especially ones meant to undermine respect for thinking and work, are rarely good guides to framing the utility of an activity.

    It's all about the information. And what we do with it.
