What to do with spent coffee grounds?
Spent coffee grounds have numerous uses, from spreading on the compost heap to making coffee cups.
The ideal use for spent coffee grounds is to use as compost, add to the garden.
A handful of coffee shops place the spent grounds outside to be picked up, more should follow this practice.

Kaffeeform turn coffee grounds into beautiful designed coffee cups, each one unique.
The cups are unusual as both reusable and recyclable. One cup and saucer are made from the grounds of six cups of espresso, plus natural resins, waxes, oils, cellulose, biopolymers and wood fibre. The cups include biopolymers. The walls of all plant cells are made of biopolymers, long chain molecules with properties allowing them to be plastically formed, and thereby eliminate use of crude oil based plastics.
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.
When next in a coffee shop, please ask what they do with their spent coffee grounds? At the very least, make available to take away for the garden.
