A light-blue mobile phone case made using recycled marine plastic waste in in Taizhou, East China's Zhejiang province recently went viral online.

By scanning a QR code printed on its back, information about the cover's raw materials, which include 8.4 grams of recycled marine plastic waste, can be retrieved.

The user can learn about how the garbage was collected, transported, stored and converted to the mobile phone case through the code.

The mobile phone case is a result of the "Blue Recycle" campaign launched by Taizhou authorities to tackle marine solid waste and boost common prosperity.

Plastic waste such as fishing nets and plastic bags and bottles accounts for up to 80 percent of marine debris in China, official statistics show.

According to Chen Xulu, an official at the Taizhou municipal bureau of ecology and environment, Taizhou has been leveraging technologies including Internet of Things and blockchain to promote the recycling of marine plastic waste.

Much of the recycled waste will be processed into particles and sold overseas by some local enterprises.

As of the end of June, more than 20 enterprises, non-profitable environmental protection organizations and universities had gotten involved in the "Blue Recycle" campaign.

Fifteen facilities designed to collect marine plastic wastes had also been set up across Taizhou, resulting in more than 12,000 plastic bottles collected near the shore.
