Using cold coffee?

[The Riff-Raff Element]

Ok so am I being a bit blonde here?!? R u trying to say that I can recycle my coffee grounds and use it to run my landrover? X

Obviously you need to drink a fair bit of coffee first, and Nescafé doesn't count. In fact, Nescafé isn't even coffee

If you want to make biodiesel on any great scale, a source of used oil is a big benefit. If you have a chippy locally they might be able to help. There are plenty of guides out there on the interwebthingie, but one tip is that ethanol (drinking & rubbing alcohol) works in place of methanol, and might be easier to get hold of. Methanol is nasty stuff.

... but, on a domestic scale, hardly worth considering apart from scientific interest. Unless, of course, you go through 100 gallons or so of coffee per day. The amount of energy you'd have to put in to recover the coffee oil from your coffee grounds, Mrs H, would far exceed the value of the oil.

+1 EROEI is very low if not negative for (most) biodiesel

i have always just poured my cold coffee into a plant, houseplant or outside, somewhere along the way heard old wives tale that it was good for them, and haven't seen otherwise. :)

Can this work with lard from pig fat?

I saw an article about a two fellas who start a company recycling coffee grounds to grow mushrooms, picking up a few green awards on the way.

Sounds like a great idea - anyone know how to do this. I can't believe it's as simple as just putting spawn in old grounds, or is it?

Sorry to take the conversation in a totally different direction but as an aside...I don't put my coffee granules on the heap anymore - or use them as a slug deterrant. I found out that although they do kill slugs, they also kill worms too. So not good for a compost heap.

Don't know whether coffee liquid would have the same affect though.
