Biomass Energy

The new process dissolves lignin into the PIL, leaving cellulose behind as a solid.

As corn prices rise and ethanol production competes with food sources, the energy industry is looking for other ways to produce biofuels.

Researchers at North Carolina State University have developed a simple, efficient and inexpensive way to extract energy-rich cellulose from non-edible plant matter, like corn husks, grasses, and wood chips.

PhD student Ezinne Achinivu  says labs often run into trouble trying to remove a protective material called lignin. It's bonded to the cellulose, but hinders its efficiency.
