Green Options

Here’s a resource we’ll have plenty of as ever wider swathes of our forests get decimated by pests like the Pine Bark Beetle. Dead trees. In an adaptation eerily reminiscent of Thomas Edison’s dictum We live like squatters, not as if we owned the property” a university has invented a technology to harvest one of the horrific effects of climate change.

The University of Georgia Research Foundation has developed an innovative way to turn dead trees into a liquid fuel and has licensed it to Tolero Energy in California. We could be driving on our dead forests as soon as 2010.

The technology represents a leap forward for the biofuels industry. Not only does the resulting biofuel need no additional refinement before blending with diesel fuel, but it is a naturally very low-sulphur biofuel.

And it would prevent additional CO2 from being released if the forest was left to decay.

But the biggest leap is in thinking of using a non-food source (at least for us humans) of biomass that we will have an ever increasing abundance of, as our climate gets worse and worse. And it doesn’t take scarce water resources to grow. Quite the contrary. Droughts and rising temperatures are all it needs.

Dead trees are one of the major sources of waste biomass, says Tolero CEO Chris Churchill.

A major infestation of the mountain pine beetle, a scourge stretching from New Mexico, in the U.S., to British Columbia, Canada, has been turning vast areas of formerly green pine forests to rust red, and slowly killing them.

The beetle infestation has been growing “exponentially” since 2006-07, according to the Forest Service management team in Laramie, Wyoming, and has so far claimed millions of acres of pine forest in Montana, Colorado, and Wyoming. North of the border, British Columbia has already lost over 33 million acres of lodgepole pine forest due to the ravages of this type of bark beetle. And more recently (in 2008), Alberta province is come under threat due to an aberrant wind storm that apparently lofted the beetles across the continental divide.
