The subpod™ is a sub-surface, high density, modular composting system that treats food waste and other organic matter, and builds healthy soil. For businesses and organisations that serve a large number of people from a centralised location, important savings and other benefits are reaped by composting on-location. The subpod™ is installed directly into the soil for high-volume processing of organic waste. Each module can process the organic waste from up to 12 people annually. Multi-module installations allow for high-volume on-site processing of organic waste without the ongoing energy expenditure. The module's low-maintenance design creates a cost-effective solution for the light industries they serve. Due to the design of the module and the microbial density, these systems can process kitchen waste not normally placed in compost, such as meat, fish, onions and citrus scraps from the kitchen. Separating organic waste becomes simple; smells, insects and rodents are also eliminated. And the subpod™ sub-surface environment naturally regulates temperature and humidity. There are no moving parts and it does not consume electricity.
