Summary: Energy efficiency is becoming the crucial issue for industry. Rising energy costs, increasing pressure to produce returns, and the awareness of the need for greater protection of the climate are creating tremendous interest in energetically optimized plant concepts. That is hardly surprising in the light of the double-digit potential for reducing costs. Modern process technology can help reduce the cost of producing cement.

1 Introduction

Energy supplies and changes in the climate are two of the major concerns of our day and age. In the opinion of the majority of scientists, the increasing demand for energy is accelerating the rate of climatic change, and that is something that the energy-intensive cement industry wants to work against. Many cement works are putting their money on attaining the highest possible efficiency in their production plants and on replacing primary raw materials and fuels by secondary materials in order to meet their obligations to reduce their CO₂ emissions.

Energy consumption, the...
