A For the present account of household food waste, edible food is discarded because planning, storage, portions, date labels and unexpected changes interact. Researchers studying household food waste use avoidable waste to mean food that was edible before it was discarded. A coordinated project on household food waste divided the work among three named studies so that observation, routine mismatch and practical evaluation would not be confused. B All three studies worked with evidence from homes, shops and municipal waste services, but they answered different questions. The Waste Composition Studies Baseline Study documented starting conditions, the Routine Mismatch Mechanism Study examined why the pattern occurred, and the Waste Prevention Implementation Study assessed whether a response was useful in practice. C The Waste Composition Studies Baseline Study used waste composition studies before any intervention began. Research on household food waste has found that household diaries are compared with weighed or sorted waste so that memory and social desirability can be assessed. It recorded missing observations and background conditions for household food waste, then repeated selected measurements so later change could be compared with the baseline established by the Waste Composition Studies Baseline Study. D The Routine Mismatch Mechanism Study considered the reported result. One point relevant to household food waste is that waste varies strongly among households and occasions, and information alone usually produces modest change. Its central hypothesis concerned routine mismatch. Evidence reviewed for household food waste shows that food bought for an expected plan becomes surplus when schedules, appetites or social events change. Analysts in the Routine Mismatch Mechanism Study tested rival explanations and did not treat the first association concerning household food waste as proof of routine mismatch. E The Waste Prevention Implementation Study examined implementation. The discussion of household food waste notes that programmes improve labels, storage, portion options and meal planning while making surplus redistribution easier. Its practical focus was waste prevention. The trial compared access, maintenance and unintended effects alongside outcomes related to waste prevention, using the starting conditions recorded by the Waste Composition Studies Baseline Study to judge change in household food waste. F The studies shared one caution: For the present account of household food waste, self-reported waste is often lower than measured waste, and composting manages material after prevention has failed. They jointly recommended measured household trials. For future research on household food waste, measured household trials will test combined interventions over enough time for new routines to settle. Their combined report kept the roles of Waste Composition Studies Baseline Study, Routine Mismatch Mechanism Study and Waste Prevention Implementation Study separate when assigning each claim about household food waste to its source.
