The Wood Pellet Industry: A Dual Threat To Poor, Rural Communities
Wood pellets are a form of biomass that is versatile, concentrated and easily transportable. But making wood pellets is dirty and energy-intensive. After tree wood is dried and ground into sawdust, it is heated and pressed through molds to form small, cylindrical chunks of dense wood fiber.
This form of biomass offers a least two advantages for energy producers. First, converting coal-fired power plants to burn wood pellets is relatively easy. Second, with much of the moisture removed, pellets are more economical to transport than raw wood. This is a significant benefit, since virtually all the industrial pellets made in the US are shipped overseas.
