Coffee grounds are what you see the barista tapping out after he or she has made your coffee. If you do not see, it is the loud banging you hear.

Coffee grounds can be used for compost or on your garden.

A few coffee shops put the grounds out in a paper carrier for gardeners to take away. More should follow their good example.

The coffee grounds can be used in cakes, instead of ground coffee.

The coffee grounds can be used for making coffee cups, jewellery, even furniture.

Or can be used for growing oyster mushrooms.

Espresso Mushroom Company using a cycle and trailer, collect the grounds from Small Batch. This explains why I have seen mushroom growing kits in Small Batch, supplied for growing oyster mushrooms at home.

The idea for growing mushrooms on coffee grounds came to the two co-founders of Espresso Mushroom Company after attending a talk by Gunter Pauli from ZERI, when he discussed how smallholder coffee growers were growing mushrooms on coffee pulp on their farms.

Each mushroom kit contains coffee from 100 espressos. What is left over can be used in the compost heap or spread on the garden.

In the natural world there is no concept of waste in time or space. Walk in ancient woodland, there is not growing piles of waste, not unless Man has been dumping waste. The output of one process is the input to another.

We should aim to close the cycle, to emulate these natural cycles, the output of one process the input to another, what we once saw as waste, the raw material for another process.
