As trees grow, they absorb harmful carbon dioxide from the atmosphere, naturally purifying our air. Through photosynthesis, the carbon gets stored in wood fibers in a tree’s roots, trunk and branches, and oxygen is released—so that people and animals have healthy air to breathe. When trees are harvested, the carbon they captured continues to be stored in the wood.
More than half the energy used in manufacturing wood products in the U.S. comes from wood itself, also known as biomass, in the forms of tree bark, sawdust and papermaking by-products. That means wood is used efficiently as the energy source to create wood products.
In fact, wood product companies in the U.S. and Canada utilize nearly 99 percent of the wood they process (pre-consumer recycling) at sawmills and at secondary wood processors such as furniture and cabinetmakers—resulting in almost no wood waste.
