Where do the wood chips come from?
Whole-tree wood chips and other low-grade woods-often referred to as “biomass materials”-are natural byproducts of responsible forestry and land management practices. Generally, whole-tree chips are produced from trees unsuitable for use in lumber or paper mills, or from the tops and branches of trees harvested for lumber. Other clean wood products, such as wood residue from sawmills, are also suitable for fuel.
