freegan

This word is so new that it's not in the OED or AHD. Freegan can be a noun (denoting a person who tries to live off scavenged/discarded/unpurchased resources as much as possible) or a it can be an adjective (describing someone--or something--related to trying to live off scavenged/discarded/unpurchased resources as much as possible). A critique of consumerism and its consequences is usually inherent in freegan activities. For one view of freeganism, see http://freegan.info/.

Freegan is a blend of free and vegan (though not all freegans are vegans). The word seems to be in circulation by the late 1990s, since (according to Wikipedia at least) Warren Oakes published a pamphlet entitled "Why Freegan?" in 1999.

And for the record, two disclaimers:

I'm not talking about the word as a way of advocating the freegan cause; my interest here is in the word itself as a relatively new item in English vocabulary.

Normally I cross-check any information I get from Wikipedia, but since this word isn't catalogued by more traditional references yet, I couldn't.
