Globally, around one-third of all food produced is lost or wasted along the food chain, while an estimated 740 million people around the world suffer from hunger and malnutrition. During the past decade, no culinary topic has energized more people around the world than has food waste. Corporate executives, environmentalists, governmental leaders, hunger organization leaders, foundations executives, educators and foodies have all jumped on the food waste bandwagon. New projects, programs, campaigns, laws and apps intended to help distribute edible food discarded or unused to food rescue operations. Local, national and international governmental bodies have issued food waste directives, passed laws, funded projects, supported public relations campaigns, and announced future waste reduction goals. For-profit and non-profit startups have been launched to decrease or profit from food waste. Equipment manufacturers have marketed new and improved products from home garbage disposal units to massive biogas plants. Despite rapid progress, questions remain. Will these efforts help control climate change? Will they help solve hunger and malnutrition? Why has food waste become so popular? What’s the next steps on food waste?
