Made from compostable co-polymers, PBAT and PLA (derived from corn or other sugar generating plants like manioc), our bags are BPI and CMA certified compostable as well as extremely strong and resilient. The resin is made to be more resistant to mechanical stress and moisture. Due to this, our bags are strong enough to keep water in so you don’t have to worry about spills. When wet or hot food scraps are collected, the bag will remain strong with no leaks. In a compost facility, however, our bags break down just like the food scraps inside it. It will turn into nothing but water, a small amount of CO2 (this is produced by all food or products in the composting process), and humus (a nutrient-rich organic material).

These bags have a very similar chemical make-up to bags except that they use a simplified and unrefined “corn-based” starch. “Corn-based” is in quotation marks because this is a bit of a misnomer – all compostable bags have a compostable polymer as their base, with a lesser percentage of a renewable resource such as starch or PLA making up the balance. These ‘corn-based’ alternatives contain starch, which has hydrophilic properties. The result is a bag that absorbs the moisture from your organic waste and will weaken, leak, and break much more easily.

TNatural fiber bags do two things really well; compost and use sustainable materials. Where they fall short is in performance. These are usually in form of kraft paper bags that don’t work in bins (even when lined with compostable cellulose), and react very poorly to wet organics. In situations where their limitations can be accommodated, these bags live up to their environmental claims very well!
