Uses for coffee grounds

"Gourmet mushrooms grow and flourish in recycled coffee grounds; thus, waste from one industry could be fertile ground for another." ... "What started as a small-scale farm supplying local restaurants and a few groceries expanded to include the mushroom kits, which now sell at 1,000 retail centers nationally. Since its founding, Back To The Roots has repurposed 1 million pounds of coffee grounds."

We pay for an organic waste company to pickup all our coffee grinds and food scraps, but this is way cooler.

Re: Growing mushrooms in coffee grounds

I should really give growing mushrooms for our own kitchen a shot, but we already have a dedicated use: we actually sell all of our grounds to a local arborist who has been doing research with U Florida on the use of spent coffee grounds to control the spread of Asian cycad scale in Sago palm trees. Scale is an insect that has was introduced to Florida in 1996 and has killed 80% of the Sago palms in South Florida. There are very costly and invasive chemical pesticide treatments for the scale, but it turns out that a consistently replenished composting bed of fresh grounds is just as effective in repelling the bugs and saving the trees.
