The modern world never tires of discussing the best ways to brew coffee–and coming up with cute coffeemakers to do it with. Designers Adrián Pérez and Mauricio Carvajal have made the process much more efficient by putting the grounds to good use, too (h/t Inhabitat). The duo’s HIFA coffee system repurposes coffee grounds to grow oyster mushrooms.
Grounds from forced-steam espresso machines are best because that sterilizes the grounds, but home-brewed grounds work, too. This coffeemaker-slash-mushroom-farm works by housing the coffee brewing portion of the device at the top, similar to a French press. The grounds go in the carafe, followed by hot water, and are allowed to steep. A mesh strainer is plunged down into the carafe to separate the grounds from coffee. The double-walled carafe is lifted off the base, coffee is poured, and the used coffee grounds are left behind in a little yellow cup.
The used grounds then get poured into the divided lower portion of the unit. Add mycelium (“mushroom roots”), spray with water every so often, and wait for tiny mushrooms to sprout, for a “potentially endless source of edible fungus.” Discard (compost!) the grounds when the substrate compartment is full.
