Sort grocery bags into 'food grade', clean, and garbage (for reuse)

At home, we sort our bags into three main categories or grades:

1. Food grade - bread bags (after shaking out crumbs), cereal bags (after eating the cereal and the crumbs), clean unused produce bags - these will be reused for packaging things like meats for the freezer compartment. Definition of 'food grade' = if food can touch the bag without being wrapped in something else, and that the bag was intended to contain food. Those bags which are clean, but previously had electronics in them, should not be used for this purpose!

2. Clean - something that is not food has been previously put in it, but the bag appears visually clean (i.e. bags from department stores that have had dry items put into them). We reuse these bags for general purpose, and when we're done using them, we classify them into our #3 category, for triple reuse. Triple reuse? [once at the store, once doing something else, and finally to contain garbage]... you could theoretically use them more than three times before their final common pathway, the garbage bag.

3. Garbage grade - these are also 'diaper grade'. We relegate these bags, which are slightly dirty, and definitely not clean or food grade, into a big bag in the closet. These bags are used for throwing out dirty diapers or lining the insides of trash cans.

Why buy garbage bags when you get bags of all sorts at the stores? This basically ensures you have an endless supply of garbage bags for life!!
