The U.S. pulp and paper industry consumes over $7 billion worth of purchased fuels and electricity per year. Energy efficiency improvement is an important way to reduce these costs and to increase predictable earnings, especially in times of high energy price volatility. There are a variety of opportunities available at individual plants in the U.S. pulp and paper industry to reduce energy consumption in a cost-effective manner. This book discusses energy efficiency practices and energy-efficient technologies that can be implemented at the component, process, facility and organisational levels. An overview of the trends, structure and energy consumption characteristics of the U.S. pulp and paper industry, along with descriptions of the major process technologies used within the industry are discussed.
