Dr. Justin Bours is a green chemist and materials/polymer scientist that has consistently leveraged his knowledge of chemical reactivity and material life cycles toward eliminating chemical risks and supporting product circularity. As Senior Technical Manager, Justin contributes to the auditing of product assessments and leads technical projects to enhance the certification program and promote sustainable product manufacture and design. He also leads the development of key proposals for future versions of the C2C Certified Products Standard’s criteria, particularly around circular products, that is based on the latest research and thinking on the circular economy. In addition, Justin has worked on several projects on advising companies on how to create frameworks for sustainable product design and facilitating product designers' ability to make sustainable design choices at the design stage. Justin’s academic work as a graduate Chemistry student at Berkeley was focused on developing synthetic strategies for a larger and more diverse library of conducting polymers and on the synthesis of organic molecular sensors for targeted explosives detection.
