A Waste Converter Machine, also known as an Organic Waste Converter (OWC), is a device designed to convert organic waste into compost or biogas through a natural process called composting or anaerobic digestion.

An Organic Waste Composter is a machine or system designed to convert organic waste — like food scraps, vegetable peels, fruit waste, garden clippings, and other biodegradable materials — into nutrient-rich compost. This compost can then be used as a natural fertilizer for soil.
