It's a Bird, It's a Limb

Alaska Airlines says it will fly a demonstration flight next year using 1,000 gallons of a biofuel made from wood waste in Northwest forests.Small family and community forest owners have hoped for a more environmentally conscious way of getting rid of slash from pruning and precommercial thinning. The answer was not biochar, despite all the enthusiasm of its proponents.

Maybe if jet fuel gets expensive enough, it will be economically viable to collect slash and turn it into fuel, as this experiment has done.

The jet biofuel is being developed by the Washington State University-led Northwest Advanced Renewables Alliance using tree branches left after a timber harvests. 

The five-year project is being supported by the U.S. Department of Agriculture.
