Grow your own mushrooms
This summer, my friend Erin left a small box on my kitchen counter. Within days, this began. I took these photos over the course of three mornings.
What in the world!?
The box came from Back to the Roots, a business that recycles used coffee grounds by inoculating them with oyster mushroom spores. The coffee grounds become the medium and food for growing mycelia. Back to the Roots note on its website that in 2012, the company is on pace to collect, divert and reuse 3.6 million pounds of coffee grounds from Peet’s Coffee & Tea, as well as collect the waste from Hodo Soy (spent tofu/okara waste); Linden Street Brewery (spent grains and hops) and Numi Tea (spent tea leaves).
All this organic waste, when just dumped into the landfill, decomposes to produce hundreds of thousands of tons of methane gas in our atmosphere, a greenhouse gas about 25 times worse than carbon dioxide for our environment.
The potential for a lot more coffee ground-oyster mushroom activities, especially in coffee-crazy Portland, is exciting. There are already a few folks in Portland who are experimenting with the same process. We’ll be touring some of their experiments in the coming months.
In the meantime, you can get your hands on one of these awesome boxes and grow your own oysters! Available at a store near you.
