- What do the coffee chains or owners do with their wasted ground coffee?
- What can you possibly use them for after they’ve been grind?
- Why can they be so useful?
I was inspired to work into this, because I felt this was a stronger concept out of all the other 3 I worked with and one of the tutors also agreed.
I’ve done a quick research online and took notes of the good useful facts and studies on wasted coffee grounds:
1. BIOFUEL/BIODEISEL - Used coffee grounds can provide a cheap and environmentally friendly source of fuel for powered cars/trucks.
2. HAIR SHINE - If you have darker hair, use leftover coffee grounds as a final hair rinse to add shine. In some cases coffee grounds are essential if you want to grow hair or use it as a hair dye.
3. ECO-EXFOLIANT - Wet the used coffee grounds and exfoliate onto skin for a cheaper and natural remedy. It’ll take away the dirt and flakiness off your skin. Research shows it also helps reduce cellulite.
4. ODOUR CONTROL - Place a bowl of used coffee grounds into freezer to remove un-wanted odours or sprinkle some into shoes and let it set overnight or even use it in a kitty litter.
5. COMPOST - Used coffee grounds put the nutrients back into the soil. They enchance the acidity of your soil while acting as a natural fertiliser (as GreenCup used on). It also helps grow your own mushrooms.
6. PEST CONTROL & REPELLANT - Ants for example can’t stand the smell of coffee and won’t cross a line of coffee grounds. It also acts as a good repellant for slugs and snails.
