Solving the pulp and paper industries' environmental problems is essential to maintaining the forest industry and accommodating the changing economic needs of forest communities. This book explores the construction of new mills--operating on new technology that does not produce pollutants--which are vital to the pulp and paper industry.
On account of rather serious losses in stored wood and wood pulp, the authors made a study of the causes of decay in wood and wood pulp and conditions which favor it, complete with mill tests, and laboratory investigations. To combat deterioration during storage, careful attention must be given to the elimination of sources of infection, and the chemicals best adapted for this are identified, and an application scheme outlined. The authors investigate fungi that inhabit pulp, which do more damage than molds, and cause certain chemical actions on ground-wood pulp. It is undoubtedly the most extensive discussion that has yet been published on this subject; the authors and the Forest Products Laboratory deserve sincere thanks.

Available technical literature on the pulping and papermaking properties of aspen was critically reviewed and deficiencies were identified in the areas of mechanical pulping, chemimechanical pulping, and chemical pulping. Technical information related to special problems of aspen usage was examined, including stained and decayed wood, bark content and debarking, and pitch deposition and de-resination.
