Trash Talk: Fresh Takes on Food Waste

Food loss and waste account for up to 10% of global greenhouse gas emissions and cost $1 trillion annually, according to the United Nations. About a third of all food grown on the planet gets wasted, rather than eaten. In developing countries, waste usually occurs between the field and the store, due to poor infrastructure, lack of refrigeration, and broken supply chains. In rich countries, most waste happens after food reaches the store, where consumers don’t buy imperfect food – or buy too much and toss what they don’t get around to consuming. How much pollution, deforestation and starvation could be reduced if we got this problem under control? And how can new tech, including AI, be brought to bear on the problem?
