The Laboratory Study will be conducted at PBRC and will include participants (N=25) from a wide array of social and economic groups will be recruited and trained on the use of the FoodImage app. Participants use the app to measure food waste (including foods with inedible parts) created during a simulated meal preparation setting, a simulated meal consumption setting with plate waste, and a simulated cabinet and refrigerator clean-out of spoiled and out-of-date foods, where the number of items and the amounts of waste for each task is randomly assigned across participants and blinded from the research staff evaluating images and coding data. These participants will denote the normal discard destination (I.e., garbage, sink/disposal, feed to animal, compost) for each item as if the waste had occurred in their own home.
