Coffee by-products and how you can creatively use them

Coffee by-products pose a major challenge to the coffee supply chain. Farmers discard more than half of the coffee fruit’s pulp, mucilage, and parchment often ends up polluting nearby land. Polluted water can create environmental problems, since it’s often channelled back into local waters when it creates dangerous algae.

The truth is that our favourite beverage causes immense environmental damage in producing countries. So how can we ease this impact? Can we reuse or repurpose the coffee’s cherry or used grounds?

Read on for five creative uses of coffee by-products and methods you can use to minimize coffee waste.

Bean and Cherry

Coffee by-product #1: Cascara

Cascara (also known as sultana in Bolivia and qishr in Yemen) is a beverage made from a coffee cherry’s dry skin. Drinkers steep the cherries like tea in hot or cold water.

In coffee producing countries like Yemen and Ethiopia, drinking cascara is an old tradition. Farmers served it every morning and on special occasions Like the beans, the taste depends on the variety.

You can buy Cascara online from Square Mile or The Barn, so why not try it yourself? You can even enhance it with spices, using everything from ginger to cinnamon or cloves to create your own signature drink.

Just remember – like coffee, cascara contains caffeine. Don’t get an overdose while experimenting!

Coffee by-product #2: Ŝelosoda

Fancy a sparkling coffee mixer? Think ŝelosoda. It’s similar to cascara, yet it tastes quite different. It naturally tastes like sweet honey and orange taste and drinkers often add organic lemon and orange juices to enhance the flavor. The added sparkle promises a refreshing drinking experience and it also goes well with some types of alcohol (I recommend gin).

This coffee by-product is sourced from the coffee farm Las Lajones in Panama, ŝelosoda is brewed in southern Germany. It’s hard to find it outside of the German market, yet if you feel like creating your own, there’s strong potential for experimentation. (Dare I say it, putting your own twist on the ŝelosoda could see you crowned champion of your local barista competition.)

And if you don’t feel like getting inventive, it can only be a matter of time until this delicious drink hits the global (online) market.

Coffee by-product #3: Coffee flour

Yes, you read that right – coffee flour! Can you imagine delicious homemade cookies or brownies, with a hint of “floral, citrus, and roasted fruit-type notes” mixing with that chocolatey goodness? This is what CF Global Holdings, a company founded by former Starbucks employee Dan Belliveau, is currently working on.

Coffee flour is made from the leftover coffee cherry, but it’s eco-friendly nature isn’t the only amazing thing about it. This gluten-free option is supposed to have five times the fibre whole grain wheat flour contains, as well as three times more iron than fresh spinach. Pretty good, right?

And if coffee flour became popular, it would provide an additional source of money for coffee farmers who could sell the dried cherries to flour mills. Hello, potential for greater economic growth and the reduction of organic waste.

Coffee flour is predicted to hit the shelves by the end of 2015, so watch out for this interesting new ingredient.

Coffee by-product #4: Fertilizer

Not only does caffeine wake you up in the morning, it can have the same effect on your plants. If, like me, you enthusiastically buy new plants only to witness their rapid demise, coffee could come to your (and your plants’) rescue.

Used coffee grounds still contain nutrients beneficial for the soil, if applied in reasonable quantities. You can either ask your local coffee shop for their spent coffee pucks or use the coffee grounds left over after your morning brew. Simply work them into the soil around the plants, and the grounds will add organic material that improves the quality of the soil.

Another use for coffee grounds around the garden is as compost. If you turn it around regularly, it will add nitrogen to your pile and compost in about three weeks.

Bonus point: the caffeine around your plants is said to keep slugs and snails away!

Coffee by-product #5: Air Freshener

Coffee grounds are not only useful helpers for your plants – they also help you out around the house.

Every once in awhile, you’ll open your fridge and (depending on what you’re storing in there) be greeted by some unpleasant smells. So here’s a smart trick: always keep a bowl of fresh, unused coffee grounds in there. It will absorb any smells, usually overnight.

The same method can be applied to smelly kitchen cupboards, or if you want to eliminate the smell of smoke in a room. Or you could use it like soap when your hands smell of garlic. Or if your car smells bad. You get the gist.

There really are so many creative uses for coffee by-products and used coffee grounds, and research is showing there may be more to come. Recent studies have investigated how the substances contained in the coffee cherry can be used in animal feed, fuel, agriculture, and even beauty products.

So why not make your own coffee soap or facial scrub at home? Be curious and experiment; your coffee could work wonders for the environment – as well as yourself!
