Residues from forest harvesting operations include logging residues (i.e. branches, tops, and stumps) left on-site, low-quality commercially grown trees, dead wood, and other noncommercial tree species. Other residues include wood that has …
Case Study 1: Two-pass
One California landowning company developed a two-pass removal system in a sawtimber/biomass harvest that optimized equipment utilization and transportation logistics. In one district, Sierra Pacific Industries typically divides operations …
Wood, coal, oil and natural gas are all made of carbon-based compounds. Burning these feedstocks releases carbon, which then becomes carbon dioxide, a major greenhouse gas. The big difference between wood and fossil fuels is that the carbon released by …
