THE ANNUAL SINGLES DAY shopping spree falls on Saturday. In order to avoid environmental pollution and save natural resources, several express delivery companies have opted for reusable plastic delivery boxes to replace the past one-time use boxes. Beijing News comments:

Pollution and waste have long been the two main problems of the domestic express delivery industry. Data show that in 2016 alone, domestic express delivery companies used 31.3 billion cardboard boxes for packaging purposes, which means as many as 72 million trees were cut down to produce the boxes.

That's why the idea of reusable plastic delivery boxes emerged. Compared with the cardboard boxes, the new ones will not only save resources but also produce less garbage.
