Kitchen Appliance Turns Waste Food Into Fertilizer
People with back yards can accomplish the same thing, free of charge, using zero energy, giving up no kitchen space, with no garbage rotting indoors, in the form of a compost pile.
I used to “operate” two compost piles, each topping out perhaps a cubic yard in volume. I’d start a new one every six months, and then use the old one, which provided fabulous fertilizer for my ~1000 square foot vegetable garden. Didn’t cost a nickel, and made great use of what nature has given us.
