Transform coffee ground into high value products

How many cups of coffee do you have per day? In Germany, 5.2 kg of coffee is consumed per capita. For some Scandinavian country like Finland and Norway, this number even higher.  To put an example, in my office with 30 people we at least drink 2 cups of coffee every day. That's 60 cups per day. And every day all the coffee ground just end up in our bin.

This coffee ground has the potential to be transformed into high-value product Instead of wasted it or composting. There are several solutions in the market which use the coffee ground as a raw material and transform it into a new product.

Kaffeeform produces reusable coffee cups from recycled coffee grounds and biopolymers. They collect coffee waste from the coffee shop and business and turn it into cups to replace traditional paper or porcelain cups. This business not only increase the value of waste coffee ground but also reduce the volume of coffee waste sent to landfill

​​​​​​​Dang Huyen Chau of the TU Dresden recycled coffee ground into fuel logs. The waste coffee grounds contains 10% oils and 20% cellulose, the important substance for fuel. A kilo log of coffee ground can produce 6000 kcal heat, more than charcoal.

  • I'm very interested in coffee for the same reason that I consume a lot of it myself. Recently, after being inspired by Blue Economy pioneer Gunter Pauli, I decided to use my own coffee grinds and grow Oyster mushrooms from their stems. So far, it's working slowly (the temperatures are still low here in Canada), but it shows the potential for using coffee grinds as a substrate for mushroom growing. Those same oyster mushrooms (30% of their mass is protein) can be eaten, fed to animals, incl. birds, insects.
    Coffee grinds can also be mixed in with clothing fabric because of its strong anti-odour effect. Oils extracted from the grinds can also be applied similarly (e.g., applied in car dashboards to remove "new-car-smell"), or even on nylon carpets.

    As I said, I am still in the early stages of this myself, but other companies like RotterZwam are already doing just this :)
