Coffee Grounds

Every year, people around the world consume 10 billion kilos of coffee beans. So, I’ve put the old thinking cap on and come up with 10 ways to reuse those coffee grounds and maybe you will find a few things in this list that you can employ within your own lives.

1. Coffee Grounds: Use as a Fertiliser for Plants and Gardens

Coffee grounds are one of the most wasted resources in the world. It’s a shame that something so useful is often thrown away without a second thought.

However, there are several ways to use used coffee grounds that can benefit not only your daily life but also the environment. For starters, used coffee grounds can be an excellent fertiliser for plants and gardens.

If you’re looking for a natural way to add nutrients to your soil, then look no further than your morning brew! Used coffee grounds are naturally rich in nitrogen which is essential for plant growth.

They also contain other minerals such as potassium and phosphorus that plants need to thrive. So, instead of throwing them away, mix your used coffee grounds into the soil around your plants or sprinkle them on top as a mulch.

And it’s not just outdoor plants that benefit from coffee ground fertiliser. You can also use it on indoor plants such as herbs and houseplants.

Just mix the used coffee grounds with some potting soil before planting or sprinkle on top of the soil once every few weeks as a natural plant food. By using spent coffee grounds as a fertiliser, you’re not only reducing waste but also creating more sustainable ecosystems around you.

You’re contributing to an eco-friendly future where soil nutrients come from natural sources rather than synthetic ones that can harm the environment in various ways. So let’s all do our part and make sure our spent coffee grounds end up where they belong – back in nature’s cycle!

2. Mix with Used Eggshells to Create a Natural Pest Repellent

Let’s be honest, chemical pesticides can be harmful, not only to pests but also to the environment. What if I told you that you could use something as simple and natural as spent coffee grounds and eggshells to keep pests away from your plants?

Yes, you read that right. If you’re looking for an organic insect repellent, mix some used coffee grounds with crushed eggshells and sprinkle it on the soil around your plants.

Coffee grounds are rich in nitrogen, potassium, and other soil nutrients. When mixed with crushed eggshells, they create a formidable barrier against slugs and snails.

Eggshells alone can be effective in keeping these slimy creatures away because their sharp edges deter them from crossing over them. However, when mixed with spent coffee grounds, the combination creates an even more potent organic insect repellent.

Not only is this method of pest control eco-friendly and sustainable for our future planet, but it’s also extremely cost-effective. Why waste money on harmful chemicals when you can use something that would otherwise go into the trash?

By using spent coffee grounds as plant food instead of throwing them out, we’re not only reducing waste but also enriching our soil naturally. So next time you brew yourself a morning cup of coffee, don’t throw away those used coffee grounds; instead mix them with some crushed eggshells for an effective organic insect repellent!

3. Make a Gritty Soap for Cleaning

When it comes to cleaning, there are a multitude of products on the market that claim to be the best at removing dirt and grime. But what if I told you that you can make your own all-natural, exfoliating soap using something you probably already have in your pantry – spent coffee grounds? That’s right, those little brown granules that used to give you a morning boost can now be repurposed for a more sustainable future.

Not only do they provide an eco-friendly alternative to chemical-laden cleaning products, but they also offer a plethora of benefits for your skin. Used coffee grounds are an excellent exfoliator that can help remove dead skin cells and promote cell turnover.

They also contain antioxidants that can help protect your skin from free radical damage and caffeine which has been shown to reduce inflammation. So not only will your skin feel cleaner and smoother, but it’ll also have a healthy glow.

To make the soap is pretty simple – just mix together equal parts coconut oil, olive oil, and used coffee grounds until well combined. Then pour into a mold and let sit for at least 24 hours before cutting into bars.

The result is an invigorating soap with a gritty texture that cleanses and exfoliates in one step. In addition to being great for your skin, this DIY soap is also great for the environment.

By reusing spent coffee grounds instead of throwing them away, you’re reducing waste and giving them another purpose beyond just providing morning caffeine.

4. Use as a Wood Stain for Furniture

If you’re looking for a natural wood finish, look no further than your morning cup of coffee. That’s right, used coffee grounds can double as an eco-friendly stain for furniture and other wooden objects.

Not only is this method affordable and sustainable, but it also gives off a unique look that can’t be replicated by traditional stains. Using coffee grounds as a wood stain is incredibly simple and easy to do.

All you need to do is mix the leftover grounds with hot water until they form a thick paste. Then, using a paintbrush or rag, apply the mixture onto your wooden surface in even strokes.

The color will deepen over time as the mixture dries and sets into the wood. Not only does this method work well on furniture, but it’s also great for DIY projects like picture frames or wooden signs.

And since it’s made from spent coffee grounds, you can feel good about using an otherwise wasted resource to create something beautiful. In addition to its aesthetic appeal, using spent coffee grounds as a wood stain is also better for the environment than traditional options.

Most commercial stains contain harsh chemicals that can be harmful to both humans and the planet. By choosing an eco-friendly option like spent coffee grounds, you’re taking one small step towards creating a more sustainable future.

5. Deodorise your Fridge

Do you ever notice that strange smell coming from your fridge? It’s an all too common problem, but fear not!

The solution is right in front of you: spent coffee grounds. Not only are they a great fertiliser for plants and gardens, but they also make an excellent fridge freshener.

The porous nature of coffee grounds makes them excellent at absorbing odours. Simply place some used grounds in a bowl or container and put it in your fridge.

Within hours, the unpleasant aroma will be replaced with a pleasant coffee scent.

6. Tenderise Meat

Meat lovers, rejoice! Not only does using coffee grounds as a meat tenderiser add a delicious depth of flavour to your steaks and roasts, it is also an environmentally friendly alternative to traditional meat tenderisers.

When using coffee grounds as a meat tenderiser, there are several methods to choose from. One option is to simply rub used coffee grounds onto the surface of the meat before cooking.

The acidity and texture of the coffee will work to break down the connective tissues in the meat, resulting in a more tender final product. For best results, let the coffee grounds sit on the meat for at least thirty minutes before cooking.

Another option is to create a coffee marinade for your meat. Simply mix together brewed coffee (using spent coffee grounds), olive oil, garlic, and your choice of herbs and spices before marinating your preferred cut of meat for several hours or overnight.

The result will be a flavourful and succulent meal that will impress even the most discerning foodie. Using spent coffee grounds as a meat tenderiser is just one small step towards creating a more sustainable future.

And that includes using it as a refreshing hand cleanser. Used coffee grounds are abrasive enough to exfoliate your skin, removing any stubborn grime and odor-causing bacteria.

Plus, the caffeine in the coffee helps stimulate blood flow and reduce inflammation, leaving your hands feeling soft and rejuvenated. To use coffee grounds as a hand cleanser, simply mix them with a small amount of water to create a paste, then rub it onto your hands for about 30 seconds before rinsing off with warm water.

The result? A natural exfoliating soap that leaves your hands smelling like fresh coffee.

Who knew that our beloved morning pick-me-up could be transformed into a gut-healthy beverage? Coffee kombucha is essentially a fermented coffee beverage that’s made by adding a SCOBY (symbiotic culture of bacteria and yeast) to sweetened, brewed coffee.

The result is a slightly sour, slightly sweet drink that’s packed with beneficial bacteria. Not only does it taste delicious, but it also helps promote digestive health and boosts your immune system.

So why not give it a try? Don’t throw away those used coffee grounds just yet – they can be put to good use in brewing your own batch of coffee kombucha.
