An estimated 931 million tonnes of food, or 17 per cent of the total food available to consumers in 2019, went into the waste bins of households, retailers, restaurants and other food services, according to new UN research.

The research, conducted to support global efforts to halve food waste by 2030, indicates that the weight roughly equals that of 23 million fully-loaded 40-tonne trucks -- enough bumper-to-bumper to circle the Earth 7 times.
