Legislators in the U.S. state of California have voted to temporarily increase the allowed concentration of heavy metals present in recycled glass packaging. In an article published on September 10, 2019, regulatory news provider Chemical Watch informed that bill SB 232 passed both the state assembly and senate. If signed by the governor, the permitted total concentration of lead, cadmium, mercury, and hexavalent chromium would increase from 100 to 200 parts per million (ppm) until January 1, 2024. The state’s senate is reported to have justified the increase arguing that “incidental lead derived from recycled materials used in making glass may disincentivize domestic glass recycling and reduce international import of recycled glass containers.”
