Oyster mushrooms growing on coffee grounds from the city

PermaFungi is a pilot project focussing on urban ecology that wants to reuse coffee grounds produced in Brussels

in order to grow delicious oyster mushrooms. The company was founded in March 2013 and recently opened a second nursery.

At the nurseries, the oyster mushrooms are grown on so-called ‘sausages’ which are made up largely of coffee grounds, which offer the ideal nutritional basis to grow oyster mushrooms. Coffee grounds are collected by bike from various outlets in Brussels (including coffee bars).

PermaFungi is not only growing mushrooms, however: it is also developing grow-your-own kits and offering workshops.
