Pulp and Chemical Potential for Western Red Cedar Utilization

The low density of western redcedar and its stringy bark create a serious handicap for chemical utilization. Bark is deleterious to pulp quality. The wood is pulpable by either the kraft or sulfate process but yields too dark a roundwood pulp. The sulfate process is critically influenced by the inclusion of any bark and therefore kraft pulping is preferred. Low yield and corrosion are problems. Fractions of cedar have been analyzed to contain thujaplicins, thujic acid, and methyl thujic. The latter two might be used for perfume bases, the former for antibiotics or insecticides. The phenolic materials are the largest of the non-volatile group and are suggested for applications as anti-oxidants.
