Uses For Coffee Waste?

#1: Post by **jyl** » February 10th, 2019, 8:14 am

What are some useful things to do with the various kinds of coffee waste?

1. Unbrewed ground coffee. From grinder adjustments, sweeping out the doser, etc. Do you brew it in some other way? Collect as a coffee medley in freezer? Use for cooking?

2. Brewed coffee grounds. What plants like this? Is there any use other than fertilizer?

3. Unground stale beans. I guess you really shouldn't have much if any of this.

I've been spreading all my old grounds, beans & the Bosco's drip tray runoff around our blueberry bushes for years. Based on our yearly harvest they seem to like it as it's the only fertilizer/compost they get.

Currently experimenting with micro greens and mushrooms. Results by end of month.

I've been growing Oyster-mushrooms on mine for a while now! Actually, ready to harvest my 3rd batch.

In The Netherlands there is an initiative selling growth-kits for this (Rotterzwam). They supply a bag of spores, a bucket and a number of instructions (these are also in Youtube). Really cool if you ask me.

Do your blueberries keep you up at night?

Do you just drop the grinds into the hopper? What is the logic behind this?

No, I make a point to never eat them after 5pm.

I think he is referring to old-stale coffee beans.......not "grinds"

Espresso grinds are a good exfoliant

If your wife has a basket of moisturizers and skin stuff.. a pinch of espresso grinds rubbed on the skin with some soap does wonders for no $.

They sell exfoliating creams with ground up walnut shells and such for $$ in the drug store.
