BioBag Biodegradable Kitchen Bags are primarily used for the collection of food scraps and other biodegradable waste in the kitchen for home or community composting. They take the mess out of the messiest kitchen job, cleaning out the bucket! These kitchen bags can also help reduce odor and bacterial build-up during food scrap collection. Made from biodegradable cornstarch, they help to eliminate regular plastic from our environment. When disposed, these kitchen bags will biodegrade as naturally as food scraps, leaving no harmful residue.
