The kitchen of the future runs on leftovers
The kitchen of Philips Design's "Microbial Home" turns food waste into compost and cooking gas. Organic waste gets thrown in a "bio-digester," where specialized bacteria processes it into methane gas to fuel the range. Then the remaining solid matter is turned into compost. So the peelings from a potato might provide the heat to cook the potato and the fertilizer to grow more potatoes.
Philips calls it "an integrated cyclical ecosystem where each function’s output is another’s input." You could also call it cradle-to-grave-to-cradle food production. And it's an elegant, nature-inspired way of making home appliances sustainable.
The Microbial Home has other reasons you never need to leave your kitchen:
The connected “larder” includes a suspended vegetable garden and a terra cotta evaporative cooling unit built into the table, providing an alternative to energy-intensive refrigeration. Other elements of the Microbial Home include a beehive, a light powered by bioluminescent bacteria, and yes, a squatting toilet that captures “excreta” for the methane digester. There’s even a hand-cranked contraption for recycling plastic.
Too bad this is all theoretical, and likely to remain that way for the foreseeable future, because it's a really neat idea. It's not just that it would save energy and monetary spending on home utilities — Americans also waste a TON of food, though granted mostly not in the form of potato peelings. It'd be nice to have a way to harness that and turn it into a benefit.
