What do you do with your excess coffee grounds? - Page 2

Postby stopvalve on Fri Jan 29, 2010 1:11 am

I read on the internet of a $250,000 grant was given to some school in New England to study how to make biomass out of the coffee grounds. First they are loaded with oil that can be extracted for bio diesel, but mainly they are after the cellulose. It seems that coffee grounds are 80% wood, perfect for making wood pellets for heating. Starbucks is supplying the coffee grounds.

I don't have a ton of volume (home-use environment), but similar to a sacrificial shot, I store my excess grounds (stuff that is clean and dry, but never made it into the portafilter on dose) and use them to purge the grouphead of solvent taste after a cafiza clean.

Ok then, on a much smaller scale, my wife and I put them in are raised planter boxes. When I was a kid my dad had a catering truck business. He would put substantial quantities of coffee grounds in on garden all the time, and we had so many earthworms the fishermen in the neighborhood would all come over to our house and dig in our garden for bait.

Have you considered an exfoliating body scrub? I wouldn't have either but leave it to my mother... A quick google will result in countless recipes.

I don't have a garden, but I have an arrangement with a friend at work. I provide her with my spent coffee pucks for compost, and she provides me with fresh fruits and vegetables in season - tomatoes, lemons, chives, herbs of all sorts, squash, cucumbers. I think shes growing melons this year.

Somehow using burnt coffee to become more burnt coffee seems like a best use case.
