Coffee chaff for redworms

jolj(7b/8a)January 28, 2011

I have 200 super sacks( 8'high X 4'wide X 4'wide & about1200-1500lbs each). Coffee waste is green beans, roasted beans, roasted ground beans that are not brewed & mostly coffee chaff. Once the chaff cools, it is wet so it goes though a heat laying in the bag in the field. After it cools, can I spread it out 12-18 inches & put the red worms in it?

The green bean are the light colored ones,the brown are roasted,the red fines is unbrewed coffee, the dark or black fines is chaff that has started to go though a heat & began to break down.

I'dd add some brown in the form of leaves, hay or lots of shredded paper/cardboard. If you can keep the pile moist and add small amounts of worms they'll take to it and start breeding once it's cool. If it's still hot you'll want to leave it till it cools to around 80F.

It's a good material. If the coffee stays moist and on it's own it tends to mold or produce some sort of fungus. If you can mix it with carbon and some water it'll compost well and makes a good bed for worms. If you want it to sit for some time you could add veggie scraps or other food and leave it for 6 months or a year while the worms eat through it.

Good luck, you've found a good source of biomass.
