The volunteers collect coffee grounds from restaurants and cafes in the city. Afterwards, the mushrooms are sold back to these as well as private people.
PRODUCTION
The mushrooms are produced in containers. The first phase of production begins with inoculating the coffee grounds with mycelium. These bags containing substrate are then stored in a dark, warm room that stimulates the natural underground. Afterwards, they are moved to a colder room with high humidity – these two rooms simulate summer and autumn. After app. a month, the mushrooms are harvested.
In between the two rooms, there is a space for hosting workshops, meetings and much more. People can also come to the production site to buy a grow kit, which is a bucket containing mycelium, to grow mushrooms in your own coffee grounds from your household.
FUTURE
Furthermore, the volunteers experiment with other possible uses of mushrooms. One experiment involved reusing the waste from the mushroom production to purify contaminated environments, since the mushrooms break down oil products. Another future initiative to be tested is using the mushrooms to make organic building insulation material.
FINANCING
The association has received support from different companies and organisations – both in terms of materials and financial means.
