Design and Experimentation of a Sustainable Solar Organic Waste Convertor (SOWaC)

Municipal Solid waste generation in metropolitan cities is rising daily due to population growth. On average, a family generates about 1.5 kilograms of waste per day, with organic waste accounting for one-third of this amount. If this organic waste is handled at the source, it will ease the load on the current solid waste management systems. Considering this critical problem of organic waste disposal, a pioneering machine was meticulously designed to treat the organic waste at its source. The machine SOWaC (Solar Organic Waste Convertor) is completely automated and converts organic waste into soil additives using bioenzymes. With a primary focus on sustainability, SOWaC is powered by solar energy. This revolutionary machine incorporates an agitator attached to a mixing container, an inlet and outlet, and a temperature sensor among its key components. The capacity of the machine is 20 kilograms. The time required for decomposition is 15-18 days with a volume reduction of 85- 90%. The soil additive obtained is dark brown, with a soft, moist consistency and odorless. After processing, the obtained soil additive was analyzed for its physico-chemical parameters. The results obtained demonstrated the effectiveness of this technology in producing valuable organic soil amendments. This machine is suitable for housing societies as well as individual houses.
