The Restriction of Hazardous Substances (RoHS) directive was adopted in February 2003 by the European Union. The RoHS directive became effective July 1, 2006. The directive restricts the use of six hazardous materials in the manufacture of various types of electronic and electrical equipment. These substances are lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers. It is closely linked with the Waste Electrical and Electronic Equipment (WEEE) directive which sets collection, recycling, and recovery targets for electrical goods. A growing number of states and countries have either already passed or are considering new legislation and regulations governing the ability of the electronic industry to ship and sell products worldwide if they are not proactively developing programs and processes to reduce the environmental impacts of their products.
