Woody Biomass
Q: Will woody biomass markets result in stems normally used for conventional forest product markets being used for energy? A: Woody biomass is likely to always be among the lowest-value forest products, thus it would not make economic sense for a logger or buyer to chip stems salable for lumber, veneer, poles and pilings, or chip 'n saw.
An Environmental Overview of Woody Biomass Utilization
The use of biomass for energy can also help mitigate greenhouse emissions. Burning woody biomass releases carbon dioxide that is a part of the present day carbon cycle. By growing or replanting to replace harvested trees, carbon is taken in by the plants, therefore making the use of woody biomass "carbon neutral".
Woody and Herbaceous Biomass Feedstocks and Their …
Woody biomass is energy dense, as exhibited by the fact that woody materials such as shrub willow have a high degree of net positive energy ratios (1:10–1:16), indicating a higher amount of energy is generated from these feedstocks than that is consumed in the form of fossil fuels in the production of feedstocks and the subsequent …
