The topic of Sustainability and Environmental Impact is closely tied to the podcast episodes, which discuss the recycled materials industry's contributions to sustainability, reducing environmental impact, and promoting a circular economy.

In HearSay Presents: Pile of Scrap with John Sacco and Michael Maslansky, the conversation highlights the importance of positioning the recycled materials industry as a renewable source of raw materials crucial for supply chains, infrastructure, and sustainability.

Additionally, in S2 Ep16: 5 Highlights from Conversations with Changemakers, the discussions with Joey Zwillinger and Christiana Figueres touch on the importance of sustainable business practices and addressing climate change, which are key aspects of Sustainability and Environmental Impact.
