Making biodegradable plastic fantastic for more shoppers

Yu Haiming has moved his high-tech company into producing plastic bags that are less harmful to the environment.

The chairman of the Dongyuan Scien-Tech Co Ltd is on a mission to cut down on pollution by rolling out more eco-friendly models for busy shoppers.

"They will biodegrade within 90 days once they are thrown away," Yu said. "Only traces of carbon dioxide and water will be left."
