What is biochar and how can it help reduce my carbon footprint?

Dear EarthTalk: What is biochar and how can it help reduce my carbon footprint? —William Jarvis, Bethlehem, PA

Biochar is a naturally occurring, fine-grained, highly porous form of charcoal derived from the process of baking biomass—and it’s been associated with fertile soils for some two thousand years. “Biochar is found in soils around the world as a result of vegetation fires and historic soil management practices,” reports the International Biochar Initiative (IBI), a trade group representing the world’s burgeoning biochar industry. “Intensive study of biochar-rich dark earths in the Amazon has led to a wider appreciation of biochar’s unique properties as a soil enhancer.”

Indeed, researchers have been hard at work perfecting their own methods for manufacturing biochar by baking biomass in giant oxygen-free kilns. The resulting biochar can then be used as a soil amendment to help restore tired, compromised farmland, not to mention contaminated industrial sites, all the while taking carbon dioxide out of the atmosphere. A liquid by-product of the biochar production process can also be converted into a carbon-neutral “biofuel” that can displace other carbon intensive fuels.
