Use less, best way to curb plastic waste

ACCORDING TO REPORTS, South China's Hainan province is aiming to introduce the first local standards for full biodegradable plastic and will totally ban the production, sales, and use of one-off, nondecomposable plastic bags and tableware. Beijing News comments:

Before the end of 2025, the province aims to completely ban the production, sales and use of plastic products listed in the Hainan Province Prohibition on the Production, Use and Disposal of Non-Degradable Plastic Products. Many people have asked what can be used to replace the non-decomposable plastic bags and tableware once they are banned. One answer is to use bags and tableware made of decomposable plastics.

That sounds a good idea. But is it practical?
