The Many Possible Uses Of Coffee Grounds

British consumers are very much into coffee: 2.4 billion cups are consumed each year. But making that coffee creates 500,000 tons of grounds each year, most of it ending up in the landfill. Advocates of better use of coffee grounds have come up with a fairly long list of alternatives to simply trashing them. Among the creative options are using grounds in: making cocktails; insect repellant; skincare exfoliant; fueling vehicles; fertilizing gardens and deterring slugs; cooking; keeping shoes and refrigerators fresh; growing mushrooms; and making paint.
