hile paring the baseline scenario for the year 2021 with a multipollutant approach (., in 2021 dollars per ton of clinker, $50 production scenario No. 8 and $48 production scenario No. 7 versus $61 from the baseline scenario).。Technology change and environmental management for cement manufacturing and Industrial pollution control in Peru Abstract:This article mainly introduced some research results made by USA In the cement industry pollution control, and in Peru, for example, analyzed the important influence that cement industrial pollution for a government. key words :pollution control cement industry industry pollution environmental management Historically, the cement industry has been challenged with the requirement of improving its manufacturing process while reducing its footprint on the environment. At the same time, global petition poses more challenges to improving the bottom line of the business. Research and development of pollution abatement technology for cement manufacturing is key for effectively operating in this new environment. These new technological advancements pete against established technologies when cement manufacturers evaluate different pollution prevention strategies.。This research developed a quantitative tool to benchmark various technologies available to produce Portland cement in the United States. The model Technology Change Evaluation for the Cement Industry (TCECI) was developed to achieve this goal considering a full cost approach. Several production scenarios were designed and evaluated to represent the current and potential future conditions of the cement industry in the United States. The decision making process to select
