An organic waste composter (OWC) is a system, often a machine.

An organic waste composter (OWC) is a system, often a machine, that accelerates the natural process of decomposition, converting kitchen scraps, yard waste, and other biodegradable materials into nutrient-rich compost (manure/soil conditioner) by using heat, aeration, and microbial action in a controlled environment, significantly reducing landfill waste and creating a valuable soil amendment. These units range from simple bins to automated devices that manage moisture and temperature, turning organic matter into usable compost quickly and reducing odor, flies, and rats.
