Apple placed restrictions on benzene, beryllium, n-hexane, trichloroethylene (TCE), and other chlorinated solvents in manufacturing operations as part of its new Regulated Substances Specification. Apple also says “All suppliers subject to breathing zone restrictions are encouraged to eliminate the use of n-hexane in cleaning agents or degreasers, as safer alternatives exist.” The NGOs Green America and China Labor Watch, which launched campaigns asking Apple to “green” its supply chain say hundreds of Apple suppliers need to be brought into compliance with these new standards and that this should be but Apple’s first step toward more environmentally sustainable production and improved working conditions.
