The PlastChem project synthesizes the evidence on more than 16 000 chemicals potentially used or present in plastics. It provides a comprehensive overview of the current scientific understanding of the chemicals in plastics, including their properties, hazards, functionalities, uses, production volumes, and regulatory status. 

The project systematically identifies and prioritizes chemicals of concern, using a hazard-based approach centered on four critical hazard criteria: (Persistence, Bioaccumulation, Mobility, Toxicity). This enables an efficient identification of plastic chemicals across 15 priority groups of chemicals requiring policy action.

The PlastChem project delivers a report which is accompanied by a comprehensive and consistent database that contains all relevant information, including six lists of chemicals based on their hazard properties and regulatory status for further prioritization, as well as a peer-reviewed scientific publication.
