This technology combines anaerobic digestion (AD) with tunnel composting to recover value from municipal biowaste. Organic waste from households, small businesses and the hospitality sector can be transformed into biogas and nutrient-rich compost, supporting circular waste management and sustainable agriculture.

Biowaste is first treated in an anaerobic digestion process to produce biogas, and the remaining material is then composted in controlled tunnels. The process ensures hygienisation, stabilisation and the recovery of nutrients that can be returned to the soil as compost.
