The objective of the sound management of chemicals is to apply managerial best practices to chemicals throughout their life cycle to prevent, and, where this is not possible, to reduce or minimize the potential for exposure of people and the environment to toxic and hazardous chemicals (i.e. through polluting emissions, use, disposal, etc.). This requires strengthened governance, and improved techniques and technologies in the production, use, storage, and disposal or recovery of chemicals.
The term life cycle originates with a methodology initially introduced in the 1970s, life-cycle assessment (LCA), which evaluates affects upon the environment and human health of a chemical substance from the moment of its extraction from the earth until the return of the substance to the ecosystem in an environmentally sound manner.
