This week I had the pleasure of speaking with Joel A. Tickner, Ph.D., Professor, Department of Public Health, University of Massachusetts Lowell, and Executive Director of Change Chemistry, to discuss green chemistry and Joel’s important work at Change Chemistry. We all appreciate that chemicals are essential to society. Green chemistry is all about engineering chemicals to diminish their adverse impacts and ensure chemicals, materials, and products are safe, efficacious, and sustainable. We discuss Joel’s pioneering work in this field, his leadership of Change Chemistry, implementation of the Sustainable Chemistry Research and Development (R&D) Act of 2019, and EPA’s implementation of amendments to the Toxic Substances Control Act (TSCA) addressing new chemical review, and much more.
