Since becoming a member of the National Committee of the Chinese People's Political Consultative Conference (CPPCC), Chen Qianlin, a professor at Guizhou University, has focused on the integrated management of bulk solid waste, offering policy recommendations.

Over the years, he has witnessed a profound shift: the concept of "turning waste into treasure" has taken deep root in the industry, with technological innovation serving as the core driver of this transformative change.

In 2025, the "dihydrate/anhydrous wet-process phosphoric acid co-production of anhydrite technology" developed by Chen's team was implemented by a leading enterprise in Guizhou. Utilizing a 100,000-metric-ton industrial facility, the company achieved stable production of high-quality anhydrite.

This innovation transformed phosphogypsum — a waste product previously requiring costly disposal — into valuable material for construction and polymer filler applications, setting a pioneering example for solid waste utilization.

Recent years have seen Guizhou introduce a series of policies to accelerate the commercialization of scientific breakthroughs. "The province and our university provide robust institutional and financial support for researchers," Chen said. "This has ignited tremendous enthusiasm for innovation and entrepreneurship among us."

Currently, Chen leads a 60-member research team of faculty and students, concentrating on provincial priority initiatives such as the precision development of mineral resources.

"Many research topics now stem directly from enterprises seeking solutions to practical production challenges," he said.

Through industry-academia collaboration, students tackle real-world projects, broadening their career prospects and enabling a seamless transition from the academic world to industry.

As the annual national two sessions approach, Chen plans to continue advocating for the resource utilization of industrial solid waste, injecting stronger momentum into green development.
