Freegan. It's fast becoming a popular word due to the impact on the environment the production of consumer goods has.
The word freegan defines someone who dedicates their life to sifting through rubbish tips, kerbside clean up days, and skip bins to find unwanted goods.
As I understand it 'freegans' are a fast growing subculture who have chosen to reduce their carbon imprint, and spending, by living of the waste of others.
Peace out.
