You are a coffee addict (like the Clean Green Cambodia team) and don’t know what to do with your leftover coffee grounds? You have a heartache every time you get rid of it? Indeed, a mountain of used coffee grounds decomposing releases methane gas and carbon dioxide into our lovely air, so it is better to reuse the coffee grounds instead of dumping them in landfills. But don’t worry, Clean Green Cambodia gathered for you all the different and useful ways you can reuse your coffee grounds… and therefore avoid throwing them away!
For every one who is lucky enough to have their own garden, it turns out that coffee grounds can be really helpful if you have a green thumb!
Composting coffee grounds helps to add nitrogen to your compost pile. It is really easy: you just have to integrate the coffee grounds onto your compost and stir the mix. Used coffee filters can be composted as well! Nevertheless, keep in mind that coffee grounds are considered green compost material (despite its colour), and therefore need to be balanced with brown compost, such as leaves, paper or wood ashes (click here to learn more about the art of composting).
Other than composting, you can also choose to use coffee grounds as fertilizer and place it directly onto the soil. As coffee grounds comprises organic material (such as potassium, phosphorus and other nutrients) it can improve drainage, water retention and aeration in the soil. However, coffee grounds tend to raise the acidity of the soil, so it is better to keep it for acid-loving plants (i.e sweet potatoes or carrots).
Another way you can use coffee grounds is to keep slugs, ants and snails away. Those insects have trouble crawling over the grit of coffee grounds, so it is best to put some at the bottom of your plants. Surprisingly, this trick also works to keep at distance…cats. Indeed, cats are known to dislike the pungent smell of coffee, and will avoid entering your garden if you scatter some coffee grounds around the areas where you don’t want cats to go.
Not only can coffee grounds keep your favourite plants safe from bugs, but it can also prevent them from entering your house!
Mosquitos can be quite a bugger, especially in Cambodia. But what if there was a natural solution to get rid of them? Coffee grounds are once again saving the day!

You can see how to create an effective and natural mosquito repellent here. To do so, you just need coffee grounds, a lighter, a bowl and a towel/cloth.
You have tried everything to get rid of cockroaches but they keep coming back? Make a cockroach trap! All you need is an inch or two of moistened coffee grounds, a jar and double-sided tape. Put the coffee grounds in the jar and line the container’s neck with double-sided tape. All you need to do now is wait for a cockroach to be drawn by the sent and get caught in the trap.
To get rid of your pet’s fleas, just rub 1 to 2 cups of coffee grounds into his fur and rinse well. Some also prefer to directly add some coffee grounds to their pet’s shampoo.
