Poplar Could be Ethanol Feedstock
Poplar trees could get more popular if they prove to be the next big ethanol feedstock.
A team of researchers at the University of Maryland, College Park, and Bowie State University is working on ways to use the hybrid trees to make ethanol and other biofuels, since they could be grown on plantations and harvested without affecting existing woodlands. Poplar, which is also known as cottonwood or aspen, is already commonly cultivated for the production of paper and timber.
The study is funded by a $3.2 million, four-year grant from the National Science Foundation’s Plant Genome Research Project, which supports research on plants seen as having economic and agricultural importance. Using the recently completed poplar genome, the researchers are focusing on ways to improve the tree’s nitrogen processing capability, which will enhance its growth rate and feasibility for use in fuel production.

NCGA president Darrin Ihnen, a corn grower from South Dakota, says among those concerns are the use of indirect land use change in making regulations for low carbon fuels and increasing the allowable blend level for ethanol in gasoline to 15 percent. “The other thing that is looming is tax policy when it comes to the ethanol industry – VEET (volumetric ethanol excise tax credit) and the import tariff,” Ihnen said on a visit last week to the
