At an industrial site in eastern Thailand, Thitipas Choddaechachainun sifts through mounds of scrap metal, circuit boards and old computer keyboards in a cavernous warehouse next to a busy highway.
Like forensic scientists, she and her team of inspectors from Thailand's industry ministry take samples of the waste and carefully bag it up to be taken away for analysis.
"A lot of this is clearly electronic waste and the company that owns this site doesn't have a licence to process it," she concludes. "This is a growing problem in Thailand."
Ms Choddaechachainun is the head of a ministry task force trying to get to grips with Thailand's e-waste problem.
Each week, she and her team head out to raid these unlicenced plants, which have popped up in recent years, mostly in rural areas, out of sight of the authorities.
