At catering establishments and the municipality of Tilburg, an electric tuktuk collects coffee grounds three times a week. This residue from your cappuccino or espresso has nutritional value. Throwing it away is a waste!
At the sustainable, circular, green entrepreneurial garden Un Bietje Groen, this 'waste' is mixed with spores of the oyster mushroom and this growing mix is hung away in refrigerated containers. A generous amount of patience plus a dash of love later, the healthy, protein-rich fungi pop out of their cocoon. And not only are they healthy for humans, the environment also benefits: producing imported beef requires about 1,000 times as much water! This takes the circular economy a step further; from waste reduction to food production!
