magine a product that can, among other things, substantially improve soil quality, reduce nutrient runoff, offer huge productivity gains and provide a source of clean, renewable energy. And if that isn’t enough, how about if it could help combat climate change. That’s the promise of biochar, a soil amendment that its proponents describe as “black gold” for agriculture, a “magic bullet” for the environment and a product that “has the potential to revolutionize the concepts of soil management.” Critics, however, say there is little scientific proof of the claims, express concern that huge plantations will be needed to produce feedstocks for biochar utilizing massive amounts of land that could be better used for other purposes including food production, and that its carbon sequestration claims could be a “carbon time bomb.” “Large-scale support for biochar is premature and dangerous,” warns Almuth Ernsting, co-founder of Biofuelwatch in a statement in which 147 organizations worldwide described biochar as “a dangerous new false solution to climate change.”
Even the most ardent advocates of biochar admit that more study and research needs to be conducted on the material. Standards for biochar are still being developed. “It’s very reasonable that folks are skeptical,” says Tripp Allen, president of Energy Anew in San Rafael, Calif., which manufactures and markets biochar under its “Biocharm” label. “They should be skeptical. We should approach biochar in a very reasoned and scientific way. I think we understand many of the benefits that biochar has on the soil. Some of the other benefits are not yet fully understood. “What I hope is that people will look into it further,” Allen says. “And once they look into it further [they will see] it is completely reliable and the benefits can be demonstrated. So there isn’t a lot of smoke and mirrors.” Biochar, which is similar to charcoal, can be created from agricultural, farm or animal waste through gasification or pyrolysis, a form of incineration that chemically decomposes organic materials by heat in the absence of oxygen. Gases given off during the process can be a source of heat or energy. Based on the type of feedstock, as well as Continued on page 3
