Backhus DC 50 compact composting unit

The Backhus DC 50 compact composting unit is a dynamic containerised in-vessel composting facility. Waste can be processed at the point of generation, making it suitable for food industry applications such as composting grease trap wastes and food wastes from grocery stores, cafeterias and hotels. Other applications include composting: industrial sludges, municipal solid waste (MSW), manure, green and yard waste, biosolids and sewage sludge.

The insulated composting unit weighs approximately 6.5 tonnes and has standard 20′ container dimensions measuring 15 m² with an interior volume of 19.5 m³ and a processing capacity of 15 m³. Capable of an annual throughput of up to approximately 450 tonnes, the retention time is three to 15 days.

Complete homogenisation of the input material and fast volume reduction of organic material is achieved with the two powerful agitators. Aeration is active/positive and active/negative including biofiltration.

Features include a high process temperature that allows for fast sanitation of contaminated feedstock and the elimination of odours; a leachate recycling circuit; and plug-and-play operation that requires only a power outlet. The unit requires a minimum of effort for transportation by hook-lift truck and the generous-sized electric hatch allows for convenient filling from three sides. It also features automatic discharge and comes with an optional roll-off undercarriage and hook.
