Is it possible to grow edible mushrooms on garden waste?

Sustainable mushrooms? Yes please!  

The idea is to use garden waste collected in Copenhagen as a growth medium for edible mushrooms, which later can be sold to selected restaurants in Copenhagen.

The potential for using waste as a growth medium has already been stablished as Beyond Coffee base their business model for producing high-quality oyster mushrooms on previously-used coffee grounds.

If the initiative becomes more than just a good idea, the next step would be to upscale the production in a setting for garden waste, so that the residue can be turned into compost.
