PCB warning label on a power transformer known to contain PCBs. Polychlorinated biphenyls (PCBs) are organochlorine compounds with the formula C 12 H 10−x Cl x; they were once widely used in the manufacture of carbonless copy paper, as heat transfer fluids, and as dielectric and coolant fluids for electrical equipment.

RoHS and other efforts to reduce hazardous materials in electronics are motivated in part to address the global issue of consumer electronics waste. As newer technology arrives at an ever-increasing rate, consumers are discarding their obsolete products sooner than ever. This waste ends up in landfills and in countries like China to be "recycled".
Waste electrical items accumulate at a dump. Prior to the implementation of the WEEE directive in the UK, waste electronic and electrical equipment was disposed of in the household (municipal) waste stream. Post the introduction of the Hazardous Waste Regulations, [8] exclusions apply to electrical and electronic equipment that are deemed ...
Polychlorinated biphenyls (PCB) constitute a wide array of now-banned organic chemicals with a variety of industrial applications. At the Kalamazoo River site, most PCBs are a result of the recycling of carbonless copy paper during the 1970s, the waste products from which were dumped into the river.
Hazardous Waste Operations and Emergency Response (HAZWOPER; / ˈ h æ z w ɒ p ər / HAZ-waw-pər) is a set of guidelines produced and maintained by the Occupational Safety and Health Administration which regulates hazardous waste operations and emergency services in the United States and its territories.

In 1976, the United States Congress passed the Toxic Substances Control Act, which banned the production of polychlorinated biphenyls, or PCBs, effective January 1978 and regulated their disposal. [2] [3] In April the United States Environmental Protection Agency promulgated new regulations governing the disposal of various chemicals, including ...
"In terms of hazardous waste, a landfill is defined as a disposal facility or part of a facility where hazardous waste is placed or on land and which is not a pile, a land treatment facility, a surface impoundment, an underground injection well, a salt dome formation, a salt bed formation, an underground mine, a cave, or a corrective action ...
Because the US does not have federal or intergovernmental e-waste policies and electronics producers still manufacture products with hazardous materials, e-waste is oftentimes dismantled without strict regulations or compliance so substances like heavy metals, flame retardants, and plastics produce public health risks.
