Implementing Cleaner Production in the pulp and paper
industry
The large–and still growing–pulp and paper industry
is a capital- and resource-intensive industry that contributes to
many environmental problems, including global warming, human
toxicity, ecotoxicity, photochemical oxidation, acidification,
nutrification, and solid wastes. This important reference for
professionals in the pulp and paper industry details how to improve
manufacturing processes that not only cut down on the emission of
pollutants but also increase productivity and decrease costs.
Environmentally Friendly Production of Pulp and Paper
guides professionals in the pulp and paper industry to implement
the internationally recognized process of Cleaner Production (CP).
It provides updated information on CP measures in:
* Raw material storage and preparation
* Pulping processes (Kraft, Sulphite, and Mechanical)
* Bleaching, recovery, and papermaking
* Emission treatment and recycled fiber processing
In addition, the book includes a discussion on recent cleaner
technologies and their implementation status and benefits in the
pulp and paper industry.
Covering every aspect of pulping and papermaking essential to
the subject of reducing pollution, this is a must-have for paper
and bioprocess engineers, environmental engineers, and corporations
in the forest products industry.
