As many of us lean back after our holiday feasts, waist-bands groaning, thoughts turn to all the left-overs. According to the United Nations, around 17 percent of all food produced globally is thrown away from shops, restaurants or households. And households are responsible for the majority of this figure.
Growing food and transporting it to shops and then homes takes a huge amount of resources in the form of land, water, energy, chemicals and fuel.
Food loss or waste accounts for 8 to 10 percent of global greenhouse gas emissions, contributing to climate change and extreme weather.
