Food systems have to be aligned with environmental sustainability and the circular economy with the focus being shifted from downstream recovery to cutting oversupply. That is the view of a new Italian environment agency study published last week. The study defines food waste as that which ‘exceeds dietary requirements and ecological capacities. Under this definition, it is estimated to represent 60% of food energy in Italy, and 63% in Europe. Food waste has emerged recently as one of the major environmental and socio-economic issues that humanity faces.
