producer of wood products. The forest products industry contributes significantly
to Oregon's economy. Changes in timber supply, land use policy, technology,
and product demand create significant impacts on the region. The activities of
the wood products industry translate into...
Two-stage sulfite pulping conditions were determined which
produced a high-yield high-hemicellulose pulp from red alder (Alnus
rubra Bong.). Those cooks with a bisulfite first-stage and an alkaline
second-stage produced pulps with the highest hemicellulose
content and the highest strength properties.
The major hemicellulose in red alder is 0-acetyl-(4-0-
methylglucurono)xylan. Removal...
This report summarizes a study which sought to provide toxicity data for pulp mills near Coos Bay through a series of toxicity bioassays. The study also surveyed benthic and beach fauna to identify macro-organisms so individual assessments of water quality requirements could be made.
