Developing an optimization model for CO2 reduction in cement production process.

The Intergovernmental Panel on Climate Change (IPCC) has predicted global rise in temperature and carbon dioxide is a major greenhouse gas responsible for global warming. The cement industry contributes approximately five per cent of the total CO₂ emitted worldwide. Ewekoro cement Plant, located in Ewekoro, Ogun State was used as a case study to evaluate the results of various modifications on cement plants operation that can impact on the plant CO₂ emissions. An economic model which objective is to highlight the best selection strategy to reduce CO₂ emissions with the least cost was developed using the industry data as part of this paper. The cement Plant achieved a significant result of 23.6 per cent reduction in CO₂ emissions per tonne of cement produced. The results were achieved mainly by applying a progressive approach prioritizing project implementation effort and feasibility. [ABSTRACT FROM AUTHOR]
