There are very few reasons that bread should end up in landfill. The first option is not to toss it in the first place. Find another use for it.If you are going to toss it, put it into your Compost, or Bokashi Bins or if you are lucky enough to live in Adelaide, a council supplied Kitchen Benchtop Bin. Fresh bread or stale bread, there are literally hundreds of easy things to do with leftover bread instead of tossing it. My favourite is breadcrumbs. Why would anyone buy breadcrumbs? But for an avalanche of left over bread possibilities, just google it and you will find: croutons, french toast, breadcrumbs, crostini, bruschetta, bread sticks, bread pudding, garlic bread and stuffing. The list is endless.One of the most efficient ways to manage bread is to freeze it fresh, especially if you are using it for lunches or toast. The slices generally don't stick together and as it thaws out, it will be as fresh as the point it entered the freezer.
Bread is probably the most wasted food in the western world, much of the waste coming from bakeries. It is cheap to make and bakeries like shelves to look full. Much of the leftovers go to charities, but too much still ends up in landfill. Even though food is readily biodegradable, it still has an adverse affect on the environment in landfill. The main problem is that in the landfill environment, food creates methane as it breaks down.
There are some incredibly good websites dedicated to helping you use up leftovers like Chef Watson or Foodwise. Foodwise is Australian, hasn't been updated in awhile and doesn't have as many recipes as Chef Watson, but it still has a lot of recipes, tips on how to buy well in the first place and even how to grow food.
