In case you have never heard of them, what makes Biobag so great is that they are 100% certified biodegradable and compostable. They are also 100% GMO free.What does this mean? It means that when the Biobag breaks down, whether in a landfill or in your home compost bin ( we recommend the Max Air Kitchen Compost Bin) the Biobag will completely break down without leaving any residue. Perhaps you have seen other blue bags or even clear bags. These are still made with plastic but have been treated with a chemical to help them break down. Biobags do not have any additional chemicals. Biobags also make public their credentials and certifications. If you still are not convinced, just remember this, if you are going to spend the extra money for a bag that is supposed to break down, you can count on Biobags for giving you your money's worth because they are certified. The next time you think of spending money on a bag that is not Biobag, you may as well be using the same old plastic bags the supermarkets still hand out. Spend your money wisely and buy only certified bags like Biobag. You can cound on Biobag for the following types of bags: Biobag Food Storage/ Biobag Compost bags, Biobag 13 Gallon Tall Kitchen Bags, Biobag 33 Gallon Lawn and Leaf bags, Biobag Dog bags, Biobag Big Dog bags, and Biobag Cat Pan Liners. When you buy Biobag by the case, shipping is free! Happy composting!
