The document discusses waste reduction initiatives in the UK food supply chain. It notes that an estimated 18.4 million tonnes of waste arises across the chain annually, with 65% from households and the rest from manufacturing (27%) and retail (8%). Case studies highlight efforts by organizations like WRAP and retailers like Waitrose to reduce waste, such as donating surplus food to charities, improving cultivation and transport practices to reduce damaged goods, and developing new packaging technologies to extend shelf life. The overall goal is to reduce the cost of food waste, estimated at £17 billion per year, and its carbon impact of 36 million tonnes of CO2 equivalents across the supply chain and in households.
