Why is household food waste a problem?
It has been estimated that up to 1/3 of all food grown is lost or wasted globally (FAO, 2013). Globally, the food industry uses approximately 30% of total energy consumption and is responsible for 29% of all anthropogenic greenhouse gas emissions (Vermeulen, 2012). Therefore, not only does waste put unnecessary strains on natural resources and increases climate change, but wasting such vast quantities of food carries an ethical burden as 793 million people remain undernourished worldwide (FAO, 2016).
In more affluent countries, post-consumer waste accounts for the greatest overall losses (Parfitt, Barthel and Macnaughton, 2010). The Swedish National Food Agency (2014) has estimated that nearly 65% of the total amount of food waste in the Swedish food supply chain occurs at the household level. 35% of this household food waste is classified as unnecessary or avoidable (Swedish National Food Agency, 2014), and approximately two thirds of household food waste is thrown away before ever being prepared as meals (Williams, 2012). Food waste at the household level is especially harmful for the environment as the largest share of environmental impact has already occurred during agricultural production, processing and transport (Sonesson et al., 2005).
