Food waste is a major part of the impact of agriculture on climate change. and other environmental issues. The Food and Agricultural Organization estimated in 2014 that food waste lost causes a global economic, environmental and social cost of $2.6 trillion a year and is responsible for 8 percent of global greenhouse gas emissions. Moreover, food waste that is not handled or reclaimed properly, i.e. through composting, can have many negative environmental consequences. For example, landfill gas from anaerobic digestion of organic matter is a major source of the greenhouse gas methane, and un-reclaimed phosphorus in food waste, leads to further phosphate mining. Moreover reducing food waste in all parts of the food system is an important part of reducing the environmental impact of agriculture, by reducing the total amount of water, land and other resources needed to feed the global community.
