Popis:	Food Residue Biomass (FORBI) is generated by drying and shredding the fermentable fraction of household food waste collected door-to-door in the Municipality of Halandri, Greece. The potential valorization of FORBI for the production of compost is investigated in this work. Two types of composters were used: an in-vessel composter with an operating volume of 28 L and a pilot-scale composter with a volume of 280 L. Stirring of both composters was carried out once every 24 hours for the homogenization of the substrate and a temperature sensor continuously recorded the temperature evolution of the composting mixture. The maximum temperature of the compost reached up to 52.2 0C for the in-vessel and 67.8 0C for the pilot scale composter, respectively. Additional parameters, such as moisture, pH, electrical conductivity, FAS, TS, VS and TKN, were evaluated. The experimental results obtained were used as a basis for the development of a model by using the AQUASIM software.
