Municipal organic waste can be transformed

OFMSW stands for Organic Fraction of Municipal Solid Waste, which refers to the “wet” component of waste recovered through differentiated collection. It basically means kitchen waste and leftovers, from food scraps to dirty napkins. OFMSW is one of the kinds of waste processed, together with sludge from purification plants, tree trimmings and waste from the agri-food industry and large-scale retail. Solid organic waste is called “wet” due to its high water content ‒ up to 70% ‒ which is entirely recycled. Through liquefaction, the energy content of the initial waste biomass is nearly all concentrated in the bio-oil, which in turn can be converted into biofuel. We obtain up to 150 kilograms of bio-oil from a ton (including the weight of the water) of organic matter.
