A brewed drink that is prepared from roasted ground coffee beans – darkly colored and bitter, yet creates a stimulating effect on humans.

It’s a beverage that is consumed by over 1 billion people across the world each day. According to the International Coffee Organization, approximately 10.4 million tons of coffee are produced every year.

We often enjoy a good cup of coffee, but have you ever wondered where the residual goes? What possibly can one do of the leftover brewed coffee – throw it? Absolutely not! We are here to give you some ideas about how you can reuse the used coffee beans. 

In a world where we are trying to create a sustainable lifestyle, we often ignore the small details that could add value to our ecosystem. Likewise, today, we talk about used coffee beans – waste which entirely isn’t a waste and can be used as compost.

What Is Composting?

Composting is a natural process of recycling organic solid waste into a valuable fertilizer that can enrich and enhance plants and soil. 

Compost can be anything from food waste to recyclable organic materials that can act as soil conditioners. 

Composting Coffee Grounds

The used coffee beans have many practical applications in your garden and homes. You need not necessarily have coffee beans to make compost. Coffee filters can be composted too. Used coffee beans are about 2% nitrogen in volume; hence they add an immense amount of nitrogen to the soil and thus improve the soil structure.

Coffee grounds make excellent fertilizer because they help in decreasing the concentration of heavy metals in the soil. It also contains various minerals like potassium, nitrogen, magnesium, chromium, which ensures healthy plant growth.

How To Use Coffee Grounds As Compost?

Spread and cultivate the reuse coffee residue directly on the soil. They can repel water if left to dry. 

 Since coffee grounds are not a nitrogen fertilizer, you can mix them with leaves or any other organic compost, which provides enough carbon and nitrogen to the soil.

Coffee as compost

Paper coffee filters can provide a suitable carbon source to the soil and can be used as compost as well. While the microorganisms break the coffee grounds, the additional nitrogen will act as a good nitrogen source for the plants. Hence, coffee filter papers can be cut into small pieces to speed up decomposition by spreading them evenly into the soil.

Apart from using coffee grounds as fertilizer, there are some more uses of used coffee.
