Shredding, not chopping, corn stover reduces cellulosic energy inputs by up to 40 percent: Purdue research

In Indiana, Purdue University researcher Dennis Buckmaster concluded from testing and analysis that shredding, rather than chopping, corn stover reduced the energy cost of converting agricultural wastes to ethanol by up to 40 percent. The technique also reduced the the size of the resulting particles, which improved access to the cellulose. The result? More cellulose for lower cost.
