Zero Food Waste Systems

Zero food waste systems are arrangements across farms, manufacturers, retailers, households, and municipalities that aim to prevent food from being wasted, redistribute edible surplus, and recycle unavoidable residues through composting or energy recovery. They build on the waste hierarchy, circular economy thinking, and food recovery programs such as food banks and gleaning. Sociologists treat waste as socially produced. Mary Douglas's work on purity and dirt shows how cultural classifications decide what counts as waste, and Zygmunt Bauman argued that consumer societies routinely produce wasted goods and lives. Tristram Stuart documented how cosmetic standards and retail practices create surplus, and Elizabeth Shove and Alan Warde have shown how routines of shopping and cooking generate waste. Harriet Friedmann and Philip McMichael's food regimes analysis places surplus within the global agrifood system, and Graham Riches has studied the rise of charitable food provision. Critics argue that redistributing surplus to food banks can normalize overproduction and treat poverty with leftovers, and that true zero waste is unrealistic. Today the concept informs food policy, date label reform, supermarket regulation, and debates about sustainability, hunger, and corporate responsibility.
