The composter bins were fed with food waste: vegetal food waste and meat waste (if required by the treatment). Vegetal food waste was delivered from a local street market and from the farm and composed of fruit and vegetable scraps, mixed with leaves and grass clippings (dry content matter of mix 15–85%). The composition of vegetal waste was very heterogeneous depending on the availability of fruit and vegetables in the market, which simulated household behavior. Meat waste consisted in raw meat scraps of edible parts, fat and bone of cattle, pigs and poultry, suitable for human consumption similar to household food waste.
