ENERGY STAR SMARTMILL Improve Your ENERGY EFFICIENCY A new ENERGY STAR Guide for the U.S. pulp and paper industry shows you how ERIC MASANET, ERNST WORRELL AND WALT TUNNESSEN I n October 2009, ENERGY STAR, a voluntary government program administered by the U.S. Environmental Protection Agency that offers businesses and consumers a broad range of energy efficiency resources to help save money and protect the environment, released an Energy Guide for the U.S. pulp and paper industry. The Guide, which can be downloaded from the ENERGY STAR website (see below) contains an overview of industry trends and energy use as well as detailed information on over 140 measures—i.e., energy and water efficient technologies and energy management practices—applicable to the typical pulp and paper mill. Measure data were compiled from a comprehensive review of information from research and trade journals, industry reports and case studies, academic and government resources (i.e., the U.S. Department of Energy’s Industrial Technologies Program), and many other sources from around the globe. Additional information was gathered via tours of U.S. pulp and paper mills and ongoing communications with U.S. pulp and paper mill personnel and industry experts. The Energy Guide focuses primarily on measures that are cost-effective and available for implementation today. Whenever possible, measure descriptions include case studies of pulp and paper mills that have successfully implemented the measure, both in the U.S. and abroad. Many case studies include specific energy and cost savings data as well as typical investment payback periods. For measures where data are not available for pulp and paper mills, the Energy Guide presents case study data from other similar industries as a rough benchmark. Lastly, for most measures, references to the technical literature such as TAPPI publications and online resources are provided, which can be consulted for further information. The Energy Guide also presents a brief overview of selected “emerging energy efficient technologies,” defined as those that have recently been developed or commercialized and hold promise for reducing energy use in the U.S. pulp and paper industry in the near future. A chapter on basic measures for water efficiency in pulp and paper mills is also provided, given the importance of water use to the industry and the increasing scarcity and expense of water as an industrial resource in the U.S. Water savings can also lead to energy savings through reduced demand for water heating, treatment, and pumping services. For ease of access, efficiency measures within the Guide are categorized as either “cross-cutting” or “process-specific.” Cross-cutting measures are those which are applicable to nearly every type of manufacturing facility and are covered in the following chapters: • Energy management programs and systems • Steam systems • Combined heat and power systems • Motor systems • Pump systems • Fan systems • Compressed air systems • Lighting Process-specific measures are those which are applicable primarily to processes that are unique to the pulp and paper industry and are covered in the following chapters: • Raw materials preparation • Chemical pulping, bleaching, and chemicals recovery • Mechanical pulping • Paper machine The Energy Guide also includes several appendices that contain useful information for mill energy and water efficiency projects. A summary of publicly-available energy management information and software tools is provided to help mill personnel identify additional resources for training, technical assistance, and selfassessment. To help mill personnel identify possible sources of financial assistance, a summary of select efficiency incentive programs at both the state and national level is provided.
