What if there was a material that could fight climate change, improve soil health, reduce landfill waste, and even make construction more sustainable? Meet biochar—a carbon-rich product with ancient roots and modern relevance.
In this episode, we welcome John Webster, a former tech executive who left his career behind to champion biochar. John breaks down the science, the story, and the potential of biochar as a game-changing climate solution. He explains how biochar is made, how it traps carbon for centuries, and its wide-ranging uses in agriculture, construction, and water purification.
Here’s what you’ll learn in this episode:
- What is biochar? Understand how biochar has captured and locked away carbon for centuries.
- How it’s being used today. Discover its role in farming, water filtration, and even concrete and drywall.
- Why biochar is more than “fancy charcoal.” Learn why biochar isn’t just about soil—it’s a part of the growing carbon credit economy.
- John’s journey from tech to climate action. Hear how he transitioned from a successful tech career to launching a biochar company.
- The future of biochar. Find out how biochar could shape sustainable farming, green construction, and carbon markets.

Biochar is much more than a material—it’s a climate solution. By turning waste into something useful, biochar helps reduce emissions, sequester carbon, and support healthier soils. This isn’t future tech—it’s ready now. Farmers, builders, and entire cities are already using biochar, and it could play a pivotal role in the future of sustainability.
