Cement Sector - Trends in Beneficial Use of Alternative Fuels and Raw Materials
This Sector Strategies report: Cement Sector - Trends in Beneficial Use of Alternative Fuels and Raw Materials analyzes recent trends in beneficial use of alternative fuels and raw materials (AFR) in cement production. The overall objective of the study is to promote increased utilization of beneficial use materials in cement kilns, where it is safe to do so, by identifying trends and cost, technical, supply/logistics, and regulatory barriers to increased utilization of these materials. Alternative fuels considered in this study include petroleum refinery spent catalyst and clarified slurry oil sediments (CSOS), scrap paper/wood, construction and demolition (C&D) debris, scrap tires, wastewater treatment sludge (biosolids), plastics, and emerging materials including scrap carpet and automobile shredder residue (ASR). The report is intended to provide information to state and federal regulators, trade associations, and other stakeholders to support and promote beneficial material reuse.

Sector Profile
Portland cement is the generic term for a fine gray powder that binds sand and gravel into concrete. It is produced by combining limestone, clay and sand, blended to exact proportions, grounded together, and then heated in a kiln to form the intermediate product - clinker. After cooling, clinker is ground with a small amount of gypsum into the portland cement product.
The U.S. cement industry's production capacity in 2001 was nearly 90 million metric tons, with an annual value of shipments of about $6.5 billion. There are 39 clinker producing companies, and 108 plants in 36 states. Nearly 80% of all U.S. plants used coal, coke or some combination of the two as kiln fuel. Nine plants reported using waste as a primary fuel, and 48 plants reported waste as an alternative fuel. Foreign companies own 78% of U.S. capacity.
Particulate matter (PM and PM-10), nitrogen oxides (NOx), sulfur dioxide (SO2), carbon monoxide (CO), and carbon dioxide (CO2) are the primary emissions from the manufacture of portland cement.
Working with the Industry
Our partnership will promote use of Environmental Management Systems by the cement industry, overcome barriers to environmental improvement, and measure results.
- Promoting Environmental Management Systems: Issue analysis for EMS initiatives are under development. Initial efforts will focus on preparing "business case" arguments for using EMS.
- Regulatory Innovation: We are examining regulations affecting the cement industry, looking for ways to improve environmental performance and reduce burden. EPA regulations for this sector include air release monitoring & reporting and solid waste management.
- Measuring Results: We are presently reviewing existing EPA and cement industry data to identify a consistent set of environmental performance indicators. You can read the Cement chapter in the Sector Strategies Performance Report.
