The mantra of the day is “no waste”! How should coffee grounds be used after brewing? Learn how to reduce waste from used coffee grounds, but more importantly, how to recycle and reuse them! We are not discussing garbage here; rather, we are discussing a raw material!
Before continuing, let’s clarify the differences between the terms:
Upcycling is the process of using trash in its current state to make something entirely new, usually worth more than the original products. Using recycled coffee grounds to make shoes is one example.
Recycling is the process of sorting, dissecting, and processing waste to produce something entirely new that is roughly equivalent in value to the original commodities. For instance, a discarded plastic bottle can be recycled and converted into a new bottle that will eventually also be recycled.
Downcycling is the process of classifying, reducing, and processing waste to extend the life cycle of the source material before permanently discarding it. For instance, an old t-shirt can be transformed into a cleaning mat.
How to reduce waste from coffee
We naturally want to generate as little garbage as possible. When discussing coffee in restaurants and households, this means:
Recycling the waste instead of dumping it in a landfill (coffee packages, used coffee grounds).
contribute to industrial upcycling or small-scale upcycling.
according to demand, buying and brewing.
FIFO (first in, first out) should be kept in mind.
The best way to reuse coffee grounds
Used coffee grounds can be recycled into a variety of industrial goods. Just a few of the online examples are provided here:
coffee oil for use in a variety of foods and beverages
Clothing and footwear for a serious coffee addict, as well as 3D printing supplies for almost anything (but not any hot items)
Tableware for a sustainable kitchen and restaurant, including cups
For the interior-focused coffee lover, furniture and decorations like sofas and lamps are appropriate.
Bioenergy: Coffee-based power has been used to light up homes, Christmas trees, and other objects, and coffee-based fuel has been tested in London’s public transportation.
Taking out the dangerous greenhouse gases from the atmosphere through carbon capture.
Ingredients for soap, shampoo, face scrubs, and other items used in personal hygiene, including cosmetic oils and solids
Your fireplace’s “fire logs” generate more heat and energy than a real wooden log does.
As you can see from the list above, the industry has a lot of commercial projects that collect coffee grounds. Google your question to see if you can discover a local business that wants your used coffee grounds.
Alternatives for a green barista
Now that we are aware of various creative solutions and labor-intensive procedures, let’s move on. But what can each of us do individually? Numerous smaller-scale actions are possible!
Instead of disposing of the grounds in a landfill, properly compost them.
Use a tiny amount of coffee grounds in your garden to enhance drainage, water retention, and aeration, to draw worms and microorganisms that are good for plant growth, or just as mulch.
Use the area as a planting site for mushrooms. The process is fascinating, enlightening, and almost addictive to watch as it moves slowly along.
Coffee grounds should be added to your worm box for fishing because worms adore this stuff.
Use coffee grinds to sand an icy walkway to prevent slips and falls.
Use coffee grounds as shampoo, a face mask, or a scrub.
Make a painting or an installation of art.
While you colour food or clothing, take in the lovely golden music.
neutralise smells, such as those in the refrigerator.
Shine up your kitchenware and silver.
Cover up dings on wooden surfaces.
What should be done with the coffee packaging and leftover coffee?
You may not be aware, but most plants enjoy coffee. So feel free to hydrate them with leftover coffee!
Making ice cubes and using them as the foundation of punch bowls or coffee drinks is one possibility.
Not to mention the countless opportunities in the kitchen. For instance, leftover coffee will find a new home in vinegar, bacon marinade, and sweet and savoury pastries.
Coffee packaging is a fantastic material for handmade crafts! Even clothing and accessories can be produced from a used coffee packaging, including key chains, ear rings, snow gliders, and more.
Coffee packet reuse is another option. For instance, we worked with Globe Hope to accomplish this in Finland. Additionally, a lot of users are creating amazing items from empty coffee packages.
Paulig just began working with a Danish start-up called Kaffe Bueno, which creates new goods from used coffee grounds. Coffee waste from Paulig’s Vuosaari roastery as well as byproducts from coffee production are being used as a raw material for nutraceuticals, cosmetics, and functional foods.
Over 2.25 billion cups of coffee are consumed everyday around the world, according to Kaffe Bueno. The grounds frequently wind up in landfills as rubbish in plastic bags combined with other junk. The 9 billion kilogrammes of coffee drank annually around the world are either considered as garbage or are not properly disposed of, resulting in tonnes of methane being produced every day as it decomposes in landfills, a greenhouse gas that is 86 times more detrimental to the environment than CO2!
There are 340m3 of methane emitted into the environment for every tonne of coffee “waste” that decomposes in a landfill. Decomposition of coffee waste has an annual environmental impact comparable to 10 million automobile emissions.
