A natural composter refers to traditional composting methods that rely on natural processes to decompose organic waste into nutrient-rich compost. Unlike mechanical composters or automated machines, natural composting does not involve electricity or complex machinery. It uses the natural breakdown of organic matter through the activity of microorganisms, fungi, insects, and worms.

The Natural Composter, also known as Organic Waste Converter (OWC), is a technology designed to efficiently compost organic waste. This can include many methods such as backyard compost bins, vermicomposting, or larger-scale composting operations that utilize outdoor windrow or aerobic composting techniques.
