Waste-to-nutrition pathways convert organic waste into food for people and livestock. Simulations of nine future scenarios in France reveal that the potential of five such pathways for reducing the environmental impacts of food and waste systems depends on process efficiencies, availability of low-carbon energy and the extent to which novel foods replace meat.
