Ant deterrent
Sprinkle the used grounds near the ants´ traces. You could also stuff their holes between the tiles. It won´t chase them away forever, but they´ll be gone for a good holiday.
Bio diesel
Recycle waste coffee grounds into advanced biofuels and biochemicals. Companies like
Bio Bean work within the existing energy and waste infrastructure, developing sustainable products and solutions to displace conventional fuels and chemicals.
The whether or not forbidden fruit these days… If you can get your hands on it, make yourself a nice tea-like brew of the dried coffee cherry husks. The nice flaky Chaff (roasted silverskin) might also be used as a (legal?) alternative: you need a handful of the fluffy stuff to brew a similar style, but non-sweet light tea.
Decoration
Use your fantasy! Make signs, coasters, glue them to your walls, melt in the bottom of candles, fill vases and put tealights in them, compose letters, numbers or words.
If you can´t make a brew, then get a chew!
Especially after consuming onions, garlic and other leeks (see also at letter H).
Those husks (see:
Cascara) can be milled to a fine
flour.
Substitute a part of your regular flour in your baking recipes with it.
There is a way to use the oils from coffee to make
garments or use the grounds to produce
bed sheets.
Been cutting those leeks, garlic and onions?
Grab some grounds and wash your hands and fingers with it (also see letters E and S).
OK kids, this is the only use I’m NOT promoting nor encouraging! It’s just… well, possible, but the
effects are quite shocking. Better to follow the advice of one of the commenters below this article: “
If you really feel you need more caffeine, just drink a second cup.”
So: Do. Not. Try. This. At. Home! (nor at your fav coffee bar).
Arm bracelets, neck laces, ankle bands… you name it.
Pinching the holes in the roasted beans can be quite a tricky operation though.
When overfermented natural coffees are not good enough for you (think descriptors like
winey,
overripe fruits,
rum/raisins), then get your scoby and
DIY!
Liquorize
Before we go to the next letter you might want to brew some
liqueur yourself, with either ground coffee, (cold-)brewed coffee or both!
Well, you might have heard of the
Coffee In Good Spirits Championship before…? Shake it like Brian Flannagan! The
M also bridges us via "
Mushrooms" to the next letter:
Grow a coffee plant, pick, process and brew and afterwards use the grounds for other plants as a
nutritient.
Oyster mushrooms also grow particularly well on coffee grounds.
Place a small tray with grounds in your car, microwave or other stinky surrounding overnight. Freshly ground preferably of course..
A very artistic way is to use the brew as
paint and for instance put it on
canvas.
Plus: lots of
Perfume makers use coffee as (part of) their base.
If those teas listed under letter
C. are not sparkling enough for you, then add some
ginger and cinnamon: kind of
Chai-ish, so there’s another
C. (making the
Circle round).
Rolling your barbecue out? Then Rub your meats with fresh grounds and roast it!
Some brewed coffee can be added to your marinades.
Go further than hand cleansing (see H.) and scrub your whole body with it. The abundant shower afterwards is like a full body ;) brew flowing slowly through the drainpit.
Kaffeeform and
Huskee are two examples of how to upcycle grounds ‘n husks into cups ‘n saucers.
And what about U? Where would U use the contents of your coffee mUɔ for? ¯\_(ツ)_/¯
“By adding sugar and silicone to coffee, the researchers were able to make a foamy brick that held together on its own and was easy to use as a filter. Soaking the brick in water caused the sugar to leach out and leave the coffee grounds open to bind to metal ions in the water.”
Get a powerful UV light and
scan the defects out of your green beans.
Masking the fact that perhaps this should have been listed under letter
M. we better relax, enjoy life (and coffee) and keep those
wrinkles away. (P.s. you can also
add yogurt to your coffee, when that washed Kenyan coffee isn’t acidic enough.)
By now you probably want to try all these prior uses out?! But wait… “
Being mindful of how you make your coffee shows you how to be mindful in every part of your life. Smell the aroma… Breathe in…, Notice, hear, listen …. Let yourself sit for a moment or two, to obtain the full flavor of… Meditating.”
Whatever you’re gonna use coffee for (except injections!): Keep enjoying coffee, either way!
