In 2024, IPEN member EARTH in Thailand coordinated with plastic recycling workers, plastic waste workers, and workers in other settings, such as office settings or other settings without occupational exposures to plastic waste to assess their exposures to chemicals in plastics. Following this work, IPEN member Centre for Environment, Justice and Development (CEJAD) in Kenya developed a similar project with plastic waste and recycling workers there.

IPEN also engaged global participants connected to the Plastics Treaty negotiations who work in settings without significant occupational exposure to plastics to assess their exposures to chemicals in plastics. 

Together the findings show that all workers experienced chemical exposures, with plastic waste and recycling workers exposed to more chemicals than the other workers.
