Last year our community implemented a green bin program for kitchen waste (along with a two-bag limit for garbage), so we were excited to begin reducing our contributions to the overflowing landfill.However, we quickly began to struggle with a smelly, buggy, nasty green bin. My son wouldn't even go near it, much less actually scrape the plates into it. We tried putting baking soda into it, we tried using paper liners, we tried washing it after emptying it, but still it remained stinky and gross. Finally I came upon the idea to keep a paper liner bag in the freezer, then scrape our plates into the bag. When the bag is full we transfer it to our deep freeze in the garage, where it stays frozen till garbage day. The frozen bags can be put into the large green bin the night before collection and will stay frozen, eliminating the sloppy, yucky mess. We have absolutely no smell, no bugs, and most importantly, my son now has no problem helping to scrape the plates!
