The Environmental Transformation Podcast with Sean Grady

The U.S. Department of Energy spends roughly $8 billion annually cleaning up nuclear waste from Manhattan Project-era sites like Hanford, Washington and Oak Ridge, Tennessee. On this episode of the Environmental Transformation Podcast, host Sean Grady sits down with Steve Moore, president and CEO of Veolia Nuclear Solutions Federal Services Group, to discuss the agency's most pressing environmental liabilities and innovative remediation technologies.

Moore describes the scale of the challenge: 56 million gallons of high-level radioactive waste currently stored in above-ground tanks at Hanford alone. He explains how Veolia's patented GeoMelt vitrification technology transforms reactive metals and radioactive waste into stable glass, and discusses the company's operations of two of the largest radioactive waste landfills in the nation.

The conversation covers emerging opportunities to revitalize federal sites as data centers and advanced reactor facilities, the "competetition" model where contractors collaborate on complex projects, and why the nuclear remediation field offers meaningful careers for young professionals seeking challenging environmental work.

Sean Grady interviews John M. Beath, P.E. (TX), LCA-CP, CEO and founder of John Beath Environmental, LLC, on the Environmental Transformation Podcast. Beath explains life cycle assessment (LCA), carbon footprints and how companies evaluate emissions across raw materials, manufacturing, transportation and product use.
In this episode, Beath breaks down LCA basics for beginners, including emission factors, primary vs. secondary data and environmental databases. He also discusses LCA 101, LCA 102 and LCA 103, transparent Excel-based modeling, EV vs. internal combustion trade-offs, grid impacts, charging and temperature effects, EPDs, and why plug-in hybrids can be a practical near-term solution for reducing combustion-related air pollution in daily driving.

Host Sean Grady talks with Kevin Lavezzo of CHEMTREC about the side of the chemical world most people never see, but responders rely on when accurate information matters. They unpack what CHEMTREC actually does, including how its Emergency Operations Center triages calls, uses tools like the Emergency Response Guidebook (ERG), and connects callers with product experts.
Lavezzo explains a common misconception: first responders can call CHEMTREC for help without paying a fee, and the team will still work to support a response even when company information is incomplete. The conversation also covers how CHEMTREC supports compliance for shippers, manages safety data sheets, provides hazmat and regulatory training, and coordinates parts of incident response through partners.
They also dig into real-world challenges, from language barriers and global response complexity to responder skill gaps with monitors and interpreting SDS details, plus emerging trends like lithium-ion battery incidents and severe weather impacts on transportation.

TerraCycle CEO and co-founder Tom Szaky returns to the Environmental Transformation Podcast with host Sean Grady for an update on what has changed since his last appearance in episode 20 in 2020. Szaky breaks down why most items are “not recyclable” because of economics, not technology, and why reuse is TerraCycle’s biggest investment through the Loop platform, including what it has taken to scale in France. The conversation also digs into U.S. recycling headwinds, extended producer responsibility, Senate Bill 54 and Senate Bill 343 in California, and why education and “making it fun” can move behavior fast. Szaky also explains TerraCycle’s current Regulation CF raise, the planned Regulation A offering, and where to learn more at www.terracycle.com.

On the Environmental Transformation Podcast, host Sean Grady talks with Charlie Sellars, author of “What We Can Do, a Climate Optimist Guide to Sustainable Living” and a director of sustainability at Microsoft.

Topics include:
• Why “crisis language” can burn people out, and how Sellars frames “pragmatic” climate optimism. (“crisis language kind of burns people out”; “The optimism language is a pragmatic language.”)
• Carbon accounting basics and early carbon footprint labels in food. (“we’re kind of at day one of carbon accounting”; “Sweet Green will actually put the, uh, carbon footprint of your meal”)
• Life cycle assessment and the “make it, move it, use it, lose it” framework. (“It’s called lifecycle assessment”; “make it, move it, use it, lose it framework.”)
• Right to repair, product longevity, and the power of buying signals and reviews. (“right to repair movement”; “voting with their, uh, their wallets”; “leaving a positive review”)
• Clean energy debates on nuclear, solar barriers, and how AI is driving data center energy demand. (“discouraging nuclear power generation”; “preventing people and companies from installing solar panels”; “what they’re used for is now ai”; “AI obviously takes a lot of energy.”)
