Chen Qianlin, a member of the Chinese People's Political Consultative Conference (CPPCC) from Southwest China's Guizhou province and a professor at Guizhou University, rushed to relevant enterprises in Liupanshui city following the Lantern Festival to conduct research and provide technical services on the management of industrial solid waste.

Chen undertakes such research and industry-academia research cooperation trips to enterprises in various cities and prefectures more than once a month.

For many years, he has been researching the efficient utilization of mineral resources and managing industrial solid waste. His consistent goal is to maximize the economic value of mineral resources while minimizing resource waste and environmental impact.

"During the mining, selecting, and processing of mineral resources, a certain amount of solid waste is inevitably generated. Reducing waste at the source is a crucial approach to managing large-scale industrial solid waste," said Chen.

Chen's proposals, submitted during his more than two years as a CPPCC member, have received attention from relevant national ministries and commissions. These range from establishing standards for the co-production of cement clinker and sulfuric acid using phosphogypsum and supporting the protection of the Yangtze River to adopting multiple measures to strengthen the management of large-scale industrial solid waste.

In this year's national two sessions, Chen will focus on recovering fluorine resources from phosphorus chemical enterprises. Addressing the low enthusiasm among some enterprises, he suggests that national policies should be formulated to mandate the recovery of fluorine resources associated with phosphate rock and clarify recovery standards.
