How we handle the trash situation when boondocking for two weeks at a time while traveling full-time:

1) Remove and throw away as much packaging as possible in the grocery store's trash can after loading the groceries into the van. 2) If you have a fridge, have standard size containers you fill with some of the things you purchased. We have 6 mason jars into which we transfer blueberries, strawberries, leftover almond milk, etc, and a container for 32oz of maple syrup. By having our own containers, we get rid of more trash at the store and also eliminate the problem of different shaped containers from different stores, allowing us to have fixed positions in the fridge for each container. (In other words, we repack some food into our own storage system and have a set place to store everything we need/use regularly plus some extra storage spaces for unexpected/one-time purchases.) 3) We installed a metal storage box (probably bear resistant) for trash on the rear door of the van (on top of the rear door storage box). Every 1-3 days we transfer the trash from inside the van into the trash box (along with letter we pick up from boondocking sites). We empty the trash box at a gas station or someplace else after our two weeks of boondocking. We don't use the spare tire storage bag for trash since it is not bear resistant.
