Did you know that waste coffee grounds that result from brewing one of the world's most popular beverages is estimated to result in more than one million tons per year in the U.S. alone and most of it ends up in landfills?

Now research at the University of Cincinnati is turning waste coffee grounds into usable fuel and the dried used coffee grounds then serve as an effective filter for biodiesel production made from other materials.

Waste from coffee fuels 13% of a Nestle manufacturing plant in Columbia and it reduces carbon emissions by 95% as well.

Perhaps in the future, coffee will not only power us with energy but maybe our cars, homes, factories and offices as well. In the need to build a greener future every little bit helps.
