Greener Grow Bags

Greener Grow Bags

Scientists developed biodegradable substrate bags for mushroom farming using PHA, a plant-based bioplastic made from waste cooking oil. When tested with oyster mushrooms (Pleurotus ostreatus), the bags held up during cultivation but naturally broke down afterward, thanks to soil microbes like Acidovorax and Schlegella. This innovation could replace conventional plastic bags, cutting down on agricultural waste and advancing more sustainable, circular mushroom cultivation.
