United Against Food Waste focuses on food waste as a social problem; the definition of food waste is 'discarded food that could be eaten by humans.' The project is transforming the City Hall Square in Copenhagen, Denmark to a 'communicative marketplace' where a wide range of stakeholders distributes food that would otherwise have been thrown out - due to wrong size, overproduction, improper labeling, day-old bread, etc. Nothing is wrong with this food, but it will normally be discarded and replaced with new products. The event is aiming at clarifying the way towards a more sustainable consumption. It’s a locally based collaborative project involving players in food’s value chain: food producers, retail, restaurants and organizations By joining the project, the partners indicate that they agree that the exploitation of the resources of the food is not right nor effective. And the green transition among all stakeholders in the sector will lead to less environmental impact.
