Students invent way to curb wood waste

摘要

When a forest is harvested by loggers or cleared for development, any woody debris that can't be sold is typically heaped into huge "slash piles" and left in place.Although an emerging biomass industry is siphoning some of that material to biomass burners for energy, limitations on that market mean most of the woody waste is disposed of by open burning, a process that "does a good job of creating bad air quality," said Craig Rawlings, president of Forest Business Network.
