In a bid to help curb climate change, a South Korean scientist has developed biodegradable bags made of materials like crab shells.

Hwang Sung-Yeon, a researcher at the Korea Research Institute of Chemical Technology believes the new bags are stronger, more durable and decompose faster than existing plastic ones.

"Climate change requires us to go fossil fuel-free," said Sung-Yeon. "Plastic is all about fossil fuel and the solution is bioplastic."

Sung-Yeon and his team identified that bioplastic typically tears apart easily. To combat this, they added stiffeners from crab shells and wood pulp to increase tensile strength from 65 to 70 megapascals. Basically, the bags are as strong as nylons used in parachutes and safety belts.
