A dozen professors yesterday joined Guiyang in Southwest China's Guizhou Province in their attempt to achieve a resource circulating economy and an environmentally friendly society.

There were nine academicians from the Chinese Academy of Sciences and the Chinese Academy of Engineering among them, in addition to three leading professors from Tsinghua University and Tongji University.

They were invited by the Guiyang government to act as advisers for the city's development plan.

The plan, devised by a task force from Tsinghua University, yesterday passed key tests by the State Environmental Protection Administration.

"The one-way economy of industrialized society, which produces, uses and then abandons products, should be totally changed to save our resources, energy and the whole environment," said Jin Yong, a professor from the Department of Chemical Engineering at Tsinghua University, who is one of the advisers.

A resource circulating economy, featuring "resources, products, regenerated resources," gives priority to the effective utilization of assets and the protection of the environment. It has been accepted around the world as a way to achieve sustainable development.
