Scannies make collecting food scraps easy. They are a companion to the vented caddy. The two work together to make the process from in-kitchen collection to drop-off as easy as possible by removing any unpleasant odors and liquid. The bag was designed with handles so you can easily carry it to your compost drop-off site. You do not need to tie a knot in the bag. Since it is not made from plastic, the Scanny bag will decompose along with your food scraps. The Scanny bag is part of a closed-loop system; its only purpose is to collect and transport food scraps
