Connecting the dots: Integrating the 'essential-use' concept in the chemical management framework of a product system

This study explores the essential-use concept within a broader chemical management framework for a product system, aimed at phasing out non-essential chemical uses. This concept mandates the elimination of all non-essential applications of chemicals of concern unless their use is crucial for health, safety, or societal functioning, and no technically and economically viable, non-regrettable alternatives available. This study traces the evolution of the essential-use concept and its current implications in chemical management, aiming to understand its applicability. By translating technical terminologies into a more understandable language, this study seeks to bridge the knowledge gap between specialists and the public, enhancing grassroots-level acceptance of the concept in product system chemical evaluation. It addresses the subjective nature of defining the essential-use concept and examining the inherent contradictions society faces in aligning it with safe uses to protect both human health and the environment. It also introduces complementary concepts to essential-use in chemical management, supporting the discussion with the development of a holistic chemical management framework for a product system. This framework incorporates the essential-use application in a way that makes the concept more easily comprehensible. The developed framework provides a systematic process for managing chemicals within a product system, simplifying chemical management at the product level until the product is deemed safe for use. This study also emphasizes the need for further research on how the essential-use concept can effectively guide the phase-out of harmful substances through grouping and prioritization, considering various perspectives and uncertainties. This is crucial for informed decision-making and promoting sustainable chemical use by eliminating non-essential chemical uses within product systems.
