Study Reveals American Hardwoods To Be World’s Most Environment-Friendly Building Materials
A new study reports confirms American hardwoods to be the world’s most environment-friendly building materials.
American Hardwood Export Council (AHEC), the prominent international trade association for the American hardwood industry, reveals in its study the strong environmental performance of American hardwoods – supported by an expanding sustainable management,forest resource, and low carbon emissions.
AHEC study has found that the carbon footprint of kiln-dried American hardwood lumber shows that confiscation of carbon during the growth of the tree more than offsets total carbon emissions during extraction, processing and shipment to India.
It also emphasizes how sea transport carries a minor factor in the overall carbon footprint of American hardwoods. Additionally, during processingmore and more dependence on bio-mass energy is a specifically important factor in keeping the overall carbon footprint of American hardwoods low.
American hardwoodsare specially known for sustainable design. By using American hardwoods, designers are rest assured that they are able to minimise their impact on the environment through all the stages of the product life cycle, including extraction, processing, use, reuse and final disposal.
At the same time, designers play an important rolein reducing waste and increasing utilization of this valued natural resource. Further, most of the American hardwood forests are owned and managed by individuals, or small companies. They are not owned or managed by large timber corporations.
Now comes the process of converting wood into usable building products. It requires significantly less energy than most other materials. Much of the energy required for the production of American hardwood products is bio-energy.
A study of 20 hardwood sawmills conducted in 2007 in north-eastern US revealed that as much as 75% of the energy needed for manufacturing kiln-dried lumber was derived from bio-mass (tree bark). Consequently, less carbon dioxide is emitted when producing American hardwood lumber than when compared with the production of many recycled materials.
