The cement industry is one of the most significant sources of anthropogenic emissions of CO2. It is connected with the specific character of the production processes, during which great quantities of CO2 are produced. Basic actions to reduce CO2 emissions recommended by the European Union's, Reference Document on Best Available Techniques in the Cement and Lime Manufacturing Industries, include: reduction of fuel consumption, selection of raw materials with low content of organic compounds and fuels with low coal contribution to heating value. All actions connected with the improvement of energy conversion efficiency of the cement production process cause CO2 emissions reduction. The use of at most acceptable by the valid standards amounts of waste as raw materials and additives for cement production, also brings about the reduction of significant part of CO2 emissions. These measures have been and continue to be pursued by the cement factories in Poland. This article describes the evolution of the cement industry in Poland over the period 1998–2008 and the resulting changes in CO2 emissions and explores the drivers for these changes. The sources of CO2 emissions in cement industry have been presented in this article as well as a discussion of potential ways to reduce Polish cement industry emissions even further.  相似文献

This paper discusses the options for the development of Tanzania's cement industry to meet the country's growing cement needs. It evaluates possible options and supports the use of dispersed small-scale vertical kiln plants to increase the capacity for Portland cement production. It also encourages the use of alternative cementitious materials in the many applications where this is possible.  相似文献

Most of the two billion tonnes of limestone consumed annually is used either as the basic raw material in the manufacture of cement or as flux input in the metallurgical industries. Of the total flux, 90% is used by the steel industry. The cement industry needs limestone in a finely pulverized form, whereas the steel industry uses it in lump form, with the lumps not less than 12 mm in size. The exploitation of limestone as flux for the steel industry must be scientifically planned. This article covers the methodology of planning, incorporating the study of the detailed status of the resource inventory, demand for limestone, exploration of new deposits, and calculating and manipulating the costs of production, transport and development of each project to match the demand pattern of steel plants. A computer was used for the optimization of supplies and their selection on planning horizons.  相似文献

A system dynamics model based on the dynamic interactions among a number of system components is developed to estimate CO(2) emissions from the cement industry in India. The CO(2) emissions are projected to reach 396.89 million tonnes by the year 2020 if the existing cement making technological options are followed. Policy options of population growth stabilisation, energy conservation and structural management in cement manufacturing processes are incorporated for developing the CO(2) mitigation scenarios. A 42% reduction in the CO(2) emissions can be achieved in the year 2020 based on an integrated mitigation scenario. Indirect CO(2) emissions from the transport of raw materials to the cement plants and finished product to market are also estimated.  相似文献
