Episode 053 - Plastic Foam, Biochar & the Fight to Replace Styrofoam | Elizabeth Lee

Plastic foam is everywhere. It protects our deliveries, insulates buildings, keeps food cold, cushions products, and makes modern logistics work. But materials like expanded polystyrene - better known as Styrofoam - are still largely fossil-based, difficult to recycle in practice, and often end up as long-lasting plastic waste.In this episode of RAW GREEN 🎤 🌵, Francesco De Lieto and Emma Mee speak with Liz Lee, founder and CEO of Carbon Cell, a UK climate tech company developing a plastic-free foam made with biochar and natural materials.We explore what plastic foam is made of, why EPS became so dominant, why it is so hard to dispose of properly, and whether biochar-based materials could offer a real alternative to fossil-based foams in packaging, insulation and construction.Liz explains how Carbon Cell’s material works, why biochar is more than just a soil amendment, what “carbon negative” really means, and why sustainable materials need to compete on performance, cost and scalability - not just environmental claims.We also discuss the wider shift away from fossil-based materials, the challenge of scaling climate tech hardware, fundraising for sustainable materials companies, regulation, supply chain resilience, and the future of plastic-free foam.Don’t forget to follow the podcast to catch the next episode.Raw Green is produced and sponsored by OBE, a sustainability consultancy specialised in Life Cycle Assessment, research and climate technologies.For more information:⁠⁠https://oneobe.com/⁠⁠⁠⁠⁠⁠https://www.linkedin.com/company/on-behalf-of-earth/⁠⁠⁠⁠⁠⁠https://www.youtube.com/@RAWGREEN_1⁠⁠Suggestions or ideas for future episodes?Email us at ⁠⁠info@oneobe.com⁠⁠Ciiiiao!

Episode 050 - How Secure Is the Energy Transition? | Uri Sadot

The energy transition is accelerating — solar, storage, electrification.But as energy systems become more connected and more distributed, they also become more exposed. In this episode of Raw Green, Francesco De Lieto and Emma Mee speak with Uri Sadot, Managing Director of Solar Defend (https://solardefend.eu/) , about a topic that is quickly moving from theory to reality: cybersecurity in energy infrastructure.Uri explains how renewable energy assets — particularly solar — are increasingly treated as critical infrastructure, and why that shift is forcing a new level of attention from regulators, investors, and operators. The conversation covers real-world incidents, including coordinated attacks on energy assets in Europe, and what these mean for the future of the grid. Beyond risk, the discussion moves into economics.How much does it actually cost to secure a solar plant?What happens when cybersecurity becomes a compliance requirement?And should resilience be factored into how energy assets are valued and financed?The episode also explores the role of AI — both as a tool for attackers and defenders — and why, despite increasing complexity, most vulnerabilities still come down to basic “cyber hygiene”.From grid resilience to investment decisions, this conversation looks at how the energy transition is evolving from a question of deployment to one of maturity — and what it takes to build a system that is not only clean, but robust.Don’t forget to follow the podcast to catch the next episode.Raw Green is produced and sponsored by OBE, a sustainability consultancy specialised in Life Cycle Assessment, research and climate technologies.For more information:https://oneobe.com/https://www.linkedin.com/company/on-behalf-of-earth/https://www.youtube.com/@RAWGREEN_1Suggestions or ideas for future episodes?Email us at info@oneobe.comCiiiiao! 🌱

Episode 048 - Are We Measuring Emissions the Wrong Way? | Spencer Brennan

For more than two decades, companies have relied on emission factors, spreadsheets, and high-level averages to calculate their carbon footprints. But what if this entire system is fundamentally flawed?In this episode of Raw Green, Francesco De Lieto and Emma Mee speak with Spencer Brennan, founder of Neutreeno (https://www.neutreeno.com/), about why today’s carbon accounting methods often fail to deliver the precision and insight needed for real decarbonisation — especially in complex, global supply chains.Spencer explains why traditional approaches can create a false sense of accuracy, how outdated databases distort Scope 3 emissions, and why spend-based carbon accounting can lead to massive overestimation. He introduces Neutreeno’s process-based modelling approach, built around thousands of real industrial processes, designed to deliver faster, auditable, and more actionable “engineering-grade” carbon data.From PlayStation consoles to steel, cement, pharma, and energy infrastructure, this conversation looks at how better data can unlock faster decarbonisation — and why measuring emissions is only useful if it leads to real change.A deep, honest discussion on the future of carbon accounting, sustainable procurement, and the tools companies will need to meet their 2030 targets.Don't forget to follow our podcast and catch up at the next episode!Raw Green is produced and sponsored by OBE, a sustainability consultancy firm specialised in Life Cycle Assessment, research and green technologies.  For more information: https://oneobe.com/https://www.linkedin.com/company/on-behalf-of-earth/https://www.youtube.com/@RAWGREEN_1Suggestions or thoughts?

Episode 045 - Turning Waste Into Platinum - Dr. Chris Egan-Morriss & Patrick King

"Can we really extract platinum from waste using bacteria?"Platinum group metals sit at the heart of the energy transition, enabling everything from catalysts and electronics to hydrogen and clean energy technologies. Yet their supply is highly concentrated, energy-intensive, and increasingly constrained.In this episode of Raw Green, Francesco and Emma explore a radically different approach: using bacteria to extract and recycle platinum group metals from waste streams.Together and based on the research of Dr. Chris Egan-Morriss and Patrick King, researchers from the University of Manchester, we unpack how metal-reducing bacteria can recover platinum from dilute industrial effluents and e-waste, why this matters for supply security, and what life-cycle assessment reveals about the real environmental impacts of biorecovery compared to mining and conventional recycling.The conversation covers the promise — and the limits — of biological recovery, the role of e-waste as an underused resource, the challenges of scaling up bioprocesses, and what needs to change for these technologies to move from the lab into industrial reality.Raw Green is produced and sponsored by OBE, a sustainability consultancy firm specialised in Life Cycle Assessment, research and green technologies.  For more information: https://oneobe.com/https://www.linkedin.com/company/on-behalf-of-earth/https://www.youtube.com/@RAWGREEN_1Suggestions or thoughts?
