This advanced combination reduces food waste volume and weight by up to 85% in less than 24 hours, all while maintaining optimal conditions for rapid, clean decomposition.

Food Waste Input
The process begins with a steady intake of food and other organic waste. Loading can be done manually or supported by Harp auxiliary accessories for minimal staff intervention
