Biochar has emerged as a promising carbon dioxide removal strategy due to its long-term stability and agronomic co-benefits. However, certification bodies often overlook soil temperature variability, and bench-scale experiments typically assume inert atmospheres unlike those in industrial systems. This study investigates the effects of pyrolysis temperature (350–575 °C) and atmosphere (nitrogen (N₂) and recirculated pyrolysis gas (PyGR)) on the carbon removal potential of Agave wercklei biochar using a temperature-dependent modeling approach.
