In Australia, sadly, recovery of food from waste on a personal mission is a not really possible- locks are present on most rubbish-rid's at the major supermarket chains, which are basically a two player oligopoly. That said, we do have organisations who are partnered with the supermarkets, t be authorised to come and pick up surplus food, and redistribute it to community houses, charities and other places of need. http://www.ozharvest.org/ is one such organisation. The http://lentilasanything.com/ community restaurant is one such recipient... and the food is amazing. It's also a great place to volunteer your time!
