The widespread use of biochar and parolysate materials could also capture significant amounts of carbon. In their book Burn: Igniting a New Carbon Drawdown Economy to End the Climate Crisis, authors Albert Bates and Kathleen Draper suggest that the amount of carbon that could theoretically be sequestered in buildings, roads, and consumer products is in the range of hundreds of billions of tons.
How would burning organic material capture carbon more than releasing carbon?

Pyrolysing is different from combustion. In pyrolysis, oxygen levels are kept very low so the substance does not burn, it merely loses a lot of volatile content and rearranges. Charcoal is the result of the pyrolysis of wood, and it is formed in small amounts when wood is burned in open air. Pyrolysing a lot would turn the entire thing into charcoal, which the author suggest could then be used in building materials to trap the carbon.
