CEMENT KiLN RECYCLING COALITION The Cement Kiln Recycling Coalition (CKRC) is a Washington, D C. based association representing member companies that operate facilities throughout the United States. Members include cement companies that recover energy from alternative fuels derived from secondary materials, companies involved in the collection, processing, management, and marketing of such fuels for use in cement kilns, as well as professional consultants and companies which provide services to the industry. Each year, the United States generates millions of tons of secondary materials that have significant energy value. To recover this energy and avoid simple disposal, the cement industry uses these materials as alternative fuels, which replaces a portion of the non-renewable traditional fossil fuels used to provide energy for the manufacture of cement. This beneficial use of alternative fuels is a significant sustainability component incorporated in cement manufacturing operations throughout the U S. and worldwide. Last spring, CKRC submitted comments to USEPA and the USDOC in response to their requests for suggestions for reducing duplicative and burdensome regulations. The comments mention several issues that are already being addressed by USEPA and that were mentioned by many other organizations. CKRC mentioned some other items, mostly relating to its core competency of waste energy recycling. As part of your ongoing rulemaking/rule review process, CKRC would like to follow up with EPA on its comments and learn more about the Agency's continuing process.
