Wood Pellets: A Good Choice for Heating

Many building owners use fossil heating fuels, such as oil or propane, for space heating. These fuels are often expensive and unstable in pricing, and are threatening the global climate and sustainability of communities. Proven alternatives to fossil heating fuels exist and are already in use across North America: Biomass fuels are a local, renewable resource for providing reliable heat. One common type of biomass is the one that will be discussed below, wood pellets.

Wood pellets are compressed by-products from the forest products industry, often wood chips and sawdust. They are a locally available and a cost-effective heating fuel with several advantages over other types of biomass. Wood pellets offer a completely sustainable alternative to other fuel sources. They burn clean, and, because of health and air quality control considerations, wood pellets are preferable to coal for electricity generation. Produced without additives and part of the natural carbon cycle, wood pellets are net neutral—generating no increased greenhouse gas emissions—if the pellet source material comes from sustainable managed forests or forestry residuals.
Much of the pellet material comes from waste sawdust, shavings, and chips remaining after lumber production; this waste is then compacted into tiny, dense pellets, which burn more efficiently than other forms of wood. Pellets are manufactured with 100% biological materials pressed through small holes in a spherical machine that binds the pellets together.

Pellets have far higher combustion efficiency because the binding process reduces moisture to less than 10%, compared to that of an average log, which is typically 50% moisture by weight. Pellets’ uniform size, shape, and weight—usually 1/2-3/4 inch (1.2-2 cm) in length by 1/4-1/3 inch (6-8 mm) in diameter—make them relatively easy to transport and store, as compared to wood logs or wood chips. Pellet uniformity also allows a machine to measure fuel quantity accurately, in order to feed in a more precise amount of fuel to make heat or electricity output.

Advantages to heating with wood pellets
• Convenient and easy to use, and can be bulk stored in less space than other biomasses fuels
• Have a high energy content, and the technology is highly efficient compared than other biomass fuels
• Wood pellets are a clean-burning renewable fuel source
• Wood pellets are produced from such waste materials
• Wood pellets are price stable compared to fossil fuels
