Regulations in catalysis are primarily focused on environmental impact, safety, and chemical handling. Key regulatory bodies include the Environmental Protection Agency (EPA) in the United States and the European Chemicals Agency (ECHA) in the European Union. Companies must comply with regulations such as the REACH (Registration, Evaluation, Authorisation, and Restriction of Chemicals) in the EU and the Toxic Substances Control Act (TSCA) in the US. Adherence to these regulations ensures safe handling and disposal of catalysts and chemicals.
