Pellet fuel is a renewable, clean-burning and cost stable home heating alternative currently used throughout North America. It is a biomass product made of renewable substances – generally recycled wood waste. There are approximately 1,000,000 homes in the U.S. using wood pellets for heat, in freestanding stoves, fireplace inserts, furnaces and boilers. Pellet fuel for heating can also be found in such large-scale environments as schools and prisons. North American pellets are produced in manufacturing facilities in Canada and the United States, and are available for purchase at fireplace dealers, nurseries, building supply stores, feed and garden supply stores and some discount merchandisers.
In short, pellet fuel is a way to divert millions of tons of waste from landfills and turn it into energy.
Many pellet manufacturers take by-products (like wood waste) and refine them into pencil-sized pellets that are uniform in size, shape, moisture, density and energy content. Why not simply burn raw biomass? First, the moisture content of pellets is substantially lower (4% to 8% water–compared to 20% to 60% for raw biomass). Less moisture means higher BTU value and easier handling especially in freezing situations with green raw biomass materials. Second, the density of pellet fuel is substantially higher than raw biomass (40 lbs. per cubic foot verses 10-25 lbs. per cubic foot in raw material form). More fuel can be transported in a given truck space, and more energy can be stored at your site. Third, pellets are more easily and predictably handled. Their uniform shape and size allows for a smaller and simpler feed system that reduces costs. This high density and uniform shape can be stored in standard silos, transported in rail cars and delivered in truck containers.
