Freeganism is an ideology of limited participation in the conventional economy and minimal consumption of resources, particularly through recovering wasted goods like food. The word "freegan" is a portmanteau of "free" and "vegan". While vegans avoid buying, consuming, using, and wearing animal products as an act of protest against animal exploitation, freegans—at least in theory—avoid buying anything as an act of protest against the food system in general.

Dumpster diving is salvaging from large commercial, residential, industrial and construction containers for unused items discarded by their owners but deemed useful to the picker. It is not confined to dumpsters and skips specifically and may cover standard household waste containers, curb sides, landfills or small dumps.
