Book Description
The ten technologies chosen for case history development are: sonic sootblowing in boilers, boiler operation on oil-water emulsified fuel, energy efficient motors, computerized control of excess air for boilers, boiler control and load allocation, driving of waste-activated sludge by multiple effect evaporation, pre-drying of hog fuel, lime kiln computerization, heat wheel for process heat recovery, and organic Rankine bottoming cycle for thermomechanical pulping heat recovery. For each case study, there is given: the company name, employee contact, plant summary, a description of the energy consuming process and of the energy-saving action, an assessment of energy savings, and the decision process leading to the adoption of the measure. A data summary for discounted cash flow analysis is tabulated for each case. (LEW).

Book Description
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 paper provides a brief overview of the U.S. EPA ENERGY STAR(R) for Industry energy efficiency guidebook (a.k.a. the"Energy Guide") for pulp and paper manufacturers. The Energy Guide discusses a wide range of energy efficiency practices and energy-efficient technologies that can be implemented at the component, process, facility, and organizational levels. Also provided is a discussion of the trends, structure, and energy consumption characteristics of the U.S. pulp and paper industry along with a description of the major process technologies used within the industry. Many energy efficiency measure descriptions include expected savings in energy and energy-related costs, based on case study data from real-world applications in pulp and paper mills and related industries worldwide. The information in this Energy Guide is intended to help energy and plant managers in the U.S. pulp and paper industry reduce energy consumption in a cost-effective manner while maintaining the quality of products manufactured. Further research on the economics of all measures?as well as on their applicability to different production practices?is needed to assess their cost effectiveness at individual plants.

Book Description
The production of paper is relatively energy-intensive: one ton of paper requires energy equivalent to about three quarters of a ton of oil in industrialized countries, and as much as 2-3 times this figure in developing countries. Although about one half of this energy requirement may be met by burning the waste products of the industry, the balance must be purchased. Faced with sharply rising energy costs in the 1970s, producers in the industrialized countries have shown that energy consumption in paper production can be substantially reduced, and that improving the efficiency of waste recovery can further decrease the requirement for purchased energy. The wide range of measures discussed in this paper include steps to improve internal energy efficiency through a variety of measures such as improved housekeeping, process modification, and water re-use, steps to improve waste utilization, and cogeneration. Preliminary analyses of the costs and benefits of such measures are included. The paper also describes the particular technical and other constraints which have so far tended to limit the introduction of similar energy-saving techniques in the pulp and paper industries of many developing countries.

Book Description
The pulp and paper industry accounts for over 12% of total manufacturing energy use in the U.S. (U.S. EIA 1997a), contributing 9% to total manufacturing carbon dioxide emissions. In the last twenty-five years primary energy intensity in the pulp and paper industry has declined by an average of 1% per year. However, opportunities still exist to reduce energy use and greenhouse gas emissions in the manufacture of paper in the U.S. This report analyzes the pulp and paper industry (Standard Industrial Code (SIC) 26) and includes a detailed description of the processes involved in the production of paper, providing typical energy use in each process step. We identify over 45 commercially available state-of-the-art technologies and measures to reduce energy use and calculate potential energy savings and carbon dioxide emissions reductions. Given the importance of paper recycling, our analysis examines two cases. Case A identifies potential primary energy savings without accounting for an increase in recycling, while Case B includes increasing paper recycling. In Case B the production volume of pulp is reduced to account for additional pulp recovered from recycling. We use a discount rate of 30% throughout our analysis to reflect the investment decisions taken in a business context. Our Case A results indicate that a total technical potential primary energy savings of 31% (1013 PJ) exists. For case A we identified a cost-effective savings potential of 16% (533 PJ). Carbon dioxide emission reductions from the energy savings in Case A are 25% (7.6 MtC) and 14% (4.4 MtC) for technical and cost-effective potential, respectively. When recycling is included in Case B, overall technical potential energy savings increase to 37% (1215 PJ) while cost-effective energy savings potential is 16%. Increasing paper recycling to high levels (Case B) is nearly cost-effective assuming a cut-off for cost-effectiveness of a simple payback period of 3 years. If this measure is included, then the cost-effective energy savings potential in case B increases to 22%.
