This is a short episode to present the CircularHorizon initiative, with Stella Harper and Darius Stulz. Darius co-founded the student initiative Circular Horizon with the goal of developing a scalable carbon removal project based on biochar. They are participating in the 100m USD XPrize Challenge by Musk Foundation. To win the grand prize, teams must demonstrate a working solution at a scale of at least 1000 tonnes removed per year.

Biochar is emerging as a powerful tool for carbon removal, and Circular Horizon, a student initiative, is aiming to win the $100M XPrize Challenge by scaling up biochar-based carbon capture.

🔥 What is biochar?
A carbon-rich material produced via pyrolysis (heating biomass in low-oxygen conditions).
🌍 Why it matters?

Locks carbon in soil for centuries
Improves soil quality & boosts agriculture
Reduces emissions of powerful greenhouse gases

Circular Horizon, with 40 student members, is looking for partners & funding to bring their project to life.
