In Taizhou, Zhejiang, Erik Solheim, former under-secretary-general of the United Nations witnessed an inspiring project — turning marine plastic waste into new products.

Fishing boats departing from Taizhou not only bring back fish but also plastic wastes from the sea. The plastic wastes are compressed and shredded in factories, turning into diamond-like particles. These particles are then made into scarves, ties, shopping trolleys, and even furniture.

From trash to treasure, from pollutant to new products, Taizhou's "Blue Circle" project demonstrates the concept of "circular economy".

In 2024, Taizhou hosted 2024 Global Forum on Hehe Culture during which Solheim was appointed as ambassador for Hehe Culture. Hehe culture, which originated in Taizhou's Tiantai mountains, embodies the concept of harmony but not uniformity.

"We have different opinions," Solheim said, "but we can still work together for peace, the environment, education, and health."
