TY  - JOUR
AB  - An economically viable system for converting catering food waste into a high quality compost has been developed. The scientific and technical requirements for composting, with food waste as the main feedstock, and fully compliant with EU regulations, to give a marketable product is described. Chemical and physical analyses of catering food waste show that it does not have the correct composition or consistent particle size for direct use as a composting feedstock. For food waste specifically there is alsoa requirement to achieve high temperatures in the composting process for long enough to destroy any pathogens present. The conversion of food waste to a high grade compost has been achieved in this work by a combination of macerating and dewatering to homogenize the feedstock and reduce the water content, with the addition of a carbon-rich bulking agent to achieve the correct C:N ratio and absorbany excess of water in a closed in-vessel composter. The composting process in a catering establishment trial was completed after 34 weeks without external heating giving a product that had been treated at sufficiently high temperatures to ensure pathogenic depletion to give a high quality product measured against BSI PAS 100 standards.
