The Restriction of Hazardous Substances Directive (RoHS) originated in the European Union (EU) and restricts the use of specific hazardous materials found in electrical and electronic equipment. Its aim is to reduce environmental harm and enhance the recyclability of electronics. RoHS legislation targets toxic substances like benzyl butyl phthalate (BBP) that pose risks to both the environment and human health. setting clear substance restrictions for manufacturers.

The RoHS Directive applies not only to general consumer goods but also to specialized equipment, such as medical devices and industrial machinery intended for the EU market. It aligns with RoHS-like regulations in other regions, ensuring global consistency in managing hazardous substances, such as benzyl butyl phthalate (BBP), in electrical and electronic products.
