Biorefineries Get A Boost

Rentech (AMEX:RTK) and partner Clearfuels Technology will get $23 million in grants to add a gasifier to existing facilities. This will help in the process of turning woody biomass into diesel and jet fuel. Other partners in the Aiea, Hawaii plant include construction company URS Corporation (NYSE:URS) and utility Hawaiian Electric (NYSE:HE).

The United States recently moved one step closer to energy independence this past Friday as the Department of Energy Secretary Steven Chu, and Agriculture Secretary Tom Vilsack, announced the first wave of grant money towards biofuel. While the corn ethanol dream in America is pretty much over, as many of the main producers have filed for bankruptcy or had their assets folded into more traditional oil companies (such as VeraSun into refiner Valero (NYSE:VLO)), biofuel from non-feed stocks or from waste are another matter.

Mobile ‘biochar’ machine to work the fields

by Martin LaMonica

An ancient technique to fertilize soil by creating charcoal from plant waste is being revived to tackle some of today’s environmental problems.

The latest company to pursue manmade charcoal, called biochar, is Biochar Systems, which has developed a biochar-making machine that can be pulled by a pickup truck. Two customers–a North Carolina farm and the U.S. Bureau of Land Management–will be begin testing the units this fall.

The unit, called the Biochar 1000, is designed to convert woody biomass, such as agricultural or forestry waste, into biochar, a black, porous, and fine-grained charcoal that can be used as a fertilizer. It uses pyrolysis–slowly burning biomass in a low-oxygen chamber–to treat 1,000 pounds of biomass per hour, yielding 250 pounds of biochar.

There still isn’t a well established market for selling biochar, but there’s growing interest among researchers in the process as a way to cut greenhouse gas concentrations. The United Nations has proposed classifying biochar as a carbon credit for sequestering carbon from the atmosphere.
