...farm in the hills of west virginia, Josh Frye isn't raising chickens just for meat. He is also raising them for their manure. Through a process that some scientists tout as a solution to climate change, food shortages and the energy crisis, Frye is transforming the waste into a charcoal-like substance called biochar that in the long run could be far better for the world than chicken nuggets. "It might look like this is just a poultry farm," says Frye. "But it's a char farm...
Burn almost any kind of organic material - corn husks, hazelnut shells, bamboo and, yes, even chicken manure - in an oxygen-depleted process called pyrolysis, and you generate gases and heat that can be used as energy. What remains is a solid - biochar - that sequesters carbon, keeping CO2 out of the atmosphere. In principle, at least, you create energy in a way that is not just carbon neutral, but carbon negative...
...look at the big picture: pyrolysis itself produces carbon dioxide emissions, and you have to consider that when you try to determine biochar's capacity for sequestration." Lehmann says he welcomes the doubts, and notes that addressing them requires "investors willing to take the risk." Which is where chicken farmer Frye, with his small biochar operation, comes in as one of the few people out there actually making a business of it. With a pyrolysis unit that can create 3-4 tons of biochar a day, he generates enough energy to heat his hen houses; and he sells the char...
