How Does It Work?
Coffee is grown in about 80 countries and is one of the world's most popular beverages and second largest traded commodity after petroleum. However, in the coffee-making and consuming process, there are many residues that are generated. These residues amount to over half of the fruit mass of coffee.
Spent coffee grounds (SCGs) represent the most abundant waste generated in coffee beverage preparation and instant coffee production, with a total annual amount estimated at 60 million tons worldwide. However, spent coffee grounds actually are a valuable resource that should be used and not thrown away. They contain large amounts of organic compounds like fatty acids, amino acids, and minerals which make them a useful byproduct that is widely underutilized.
Repurposing Coffee Grounds
At Coffee Reimagined, we are passionate about repurposing coffee grounds to decrease global emissions. We collect used coffee grounds from local coffee shops and turn them into fertilizer, which can be used to grow plants. This not only prevents the coffee grounds from ending up in landfills but also helps reduce the need for synthetic fertilizers, which can have harmful effects on the environment.
What We Do
Educating Others
We believe that education is key to creating a sustainable future. That's why we host workshops and events to teach others about the benefits of repurposing coffee grounds and the impact it can have on the environment. We also work with local schools and community groups to spread awareness and inspire others to make a difference.
Building A Community
We believe that change starts with community. That's why we work closely with local coffee shops and community members to collect coffee grounds and create a more sustainable future. We also offer volunteer opportunities for those who want to get involved and make a difference.
How do we repurpose?
At Coffee Reimagined we have researched and developed multiple ways to repurpose coffee grounds so that you can use coffee grounds however you see fit.
Fertilizer
Our first use for spent coffee grounds is as a compost starter or fertilizer. Because of their high nitrogen, phosphorus, and potassium content, coffee grounds can be used as an effective compost starter or fertilizer. To use coffee grounds as a fertilizer all you need to do is sprinkle the grounds directly into the soil and lightly rake it in. Coffee grounds add organic material to the soil and help with water retention, aeration, and drainage.

Composting
Another effective use for coffee grounds is composting. Coffee grounds are a great source of nitrogen which is essential to plant growth as it is a key component of proteins and chlorophyll. The 20:1 carbon to nitrogen ratio in coffee makes it a perfect "green" composting material to compliment "brown" composting material like dried leaves. Because of this coffee grounds can be utilized in hot composting, a method of quickly and efficiently producing compost.

Garden Pest Repellent
Coffee grounds give off a strong odor that will instantly repel moles. However, when coffee grounds are collected, they are moist to the point where they form lumps and cannot be easily spread. To decrease this moisture, we have developed a solution using natural clay in combination with coffee grounds. This clay helps to dry the coffee grounds and increase the longevity of the coffee aroma so that pests will be repelled for longer
Our Goal
Through our efforts we hope to see a reduction of coffee grounds in landfills since when coffee grounds break down in landfills, methane, a gas which has a greenhouse effect 28 times higher than carbon dioxide, is released. In addition during the decomposition process in a landfill, coffee grounds release liquid byproducts known as leachate. Leachate is a toxic liquid that can potentially contaminate surrounding soil and groundwater if not properly managed.
