IVC Technology at Cambridge Site

In-vessel Composting

Envar Composting uses industry-leading technology and ever-evolving processes developed over more than 30 years to process organic waste in the most efficient, safe, cost effective and sustainable manner to produce a high-quality end product. From entering the site as waste to leaving as nutrient-rich compost and topsoil, the path of everything which comes in and goes out is fully traceable, with a clear and demonstrable provenance.

The flagship Cambridge site utilises a computer-controlled double-ended batch tunnel in-vessel system, capable of safely composting all manner of materials including biowaste, food and green waste, sewage and industrial sludges, manure, municipal solid waste and anaerobic digestion (AD) residue. Developed over a 25 year period by recognised industry-leaders GiCom, the system also enables the biological drying of municipal solid wastes and other waste streams containing organics, and the production of mushroom composts from poultry litter and straw. The system is fully enclosed with a biofilter to minimise emissions, and is fully compliant with strict UK Government Animal By-Products Regulations (ABPR).
