Wan Tingting, 37, a graduate of Guangxi University with a master's degree in art, finds herself now an expert in another form of art — the art of recycling.

For 10 years, she has been working at Yuguang Gold & Lead in Jiyuan, Henan province, now acting as a deputy section chief of the plastic workshop at its Regenerated Lead Plant.

As a nonferrous metal giant and a large international conglomerate with global sourcing and global sales, Yuguang has been transporting mountains of rocks, mineral powder and waste batteries from around the world and maximizing the full recovery of all available resources, before making the leftovers into brick-type building materials, she said.

"When I followed my husband to work at Yuguang 10 years ago, I was a complete novice, knowing nothing about the recycling industry," Wan recalled.
