Your comments show that many of us use coffee grounds to fertilize plants, and this is undoubtedly a good thing.
But there are those who, before fertilizing the plants, use the coffee grounds collected from the local cafes to cultivate.
Well yes: it is a landless cultivation, only with coffee grounds, and it produces mushrooms!
These mushrooms are then sold in local fairs or in local restaurants: in Tuscany.
What better name than Espresso Mushrooms?
Among other things, ironically, this business was born in a former shoe factory.
Funghi Espresso then participated in Expo 2015 receiving consensus and acknowledgments.
Mushrooms Espresso is inspired by Gunter Pauli‘s Blue economy becoming part of the concept of Smart city, but even more of Urban farming.
Antonio Di Giovanni, one of the creators of the Startup Mushrooms Espresso, is also the founder of Circular Farm whose production cycle illustrates in detail the composting process and hydroponic cultivation.
Have you already tried the hydroponic method, that is, out of the ground?
