A critical piece of this process is to identify potential environmental hazards within these products. In this session, experts will explain the role toxicity testing plays in sustainable manufacturing and development. How can these tools be used to better understand our environment and mitigate harm? Attendees will leave with an understanding of toxicity testing and the role it plays in sustaining the circular economy.
