Cement industry bear the brunt in the tide of resisting global warming because of large carbon dioxide emission. Five low-carbon measures and implementation approach to Chinese cement industry was put forward: Increasing industrial concentration degree and developing new dry process cement; Processing waste in cement kilns and reducing the use of raw materials and fuels; Increasing the amount of admixture in cement; Producing cement from calcium oxide content solid waste; Taking energy-saving measures such as cogeneration and grinding technology.

Carbon Dioxide Mitigation

This paper primarily presents on carbon dioxide mitigation by marine microalgae. Among the potential marine microalgae,Nannochloropsis oculatahas been identified as a promising species which can be utilized to reduce carbon dioxide concentration via photosynthesis process. The growth ofN. oculataand lipid synthesis for biodiesel production is influenced by various aspects. The aspects that are focused in this paper include light source and intensity, temperature, carbon dioxide concentration, and photobioreactor design. Besides, emerging technologies that are able to increase the efficiency of carbon dioxide reduction were also highlighted. As a whole,N. oculatamight play a key role in reducing the global carbon dioxide emission as well as enhancing the biodiesel production.

The article emphasizes the inevitability of the formation of CO2 in the production of thermal and electric energy with the combustion of fossil fuel and analyzes the sources of carbon dioxide generation at power facilities in Kazakhstan. Technologies for the production of electrical and thermal energy with reduced generation of carbon dioxide, which are being implemented in a short time, are discussed. A possible method for quantifying the level of CO2 emissions for the conditions of Kazakhstan is shown, through the use of the specific consumption of conventional (carbon) fuels for production as a unit of thermal energy and / or electricity. A number of available and relatively cheap technological solutions are presented, which, when implemented, can significantly reduce carbon dioxide emissions. It is noted that these technologies can be implemented administratively and economically, and the formulations of the required decisions of the Government are given. For each of the proposed technologies, an assessment of possible volumes of reduction of carbon dioxide emissions is given and difficulties that may be encountered during implementation are indicated. A scheme for determining the degree of participation of a particular country in global carbonation is considered and it is shown that, depending on the method of "spreading" the total volume of emissions of a particular country, one and the same country can be both among prosperous countries and among a number of countries to which it is necessary to apply strict "carbon" taxes. It is noted that the determination of the share of a particular country in the form of emissions per unit area of the country's territory seems to be more "fair" taking into account the global nature of pollution.

Reduce Carbon Dioxide

AbstractIn the early days of industrialisation, economists believed that the ramifications of economic growth will far outweigh the potential damage to the environment. Today the concern is the rising magnitude of emissions. Many economies are under immense pressure to reduce carbon dioxide emissions. Carbon taxation and absorption technologies seem to be the main mechanisms controlling emissions in different nations. China proposed her target of reducing carbon dioxide emissions by 40-45% by 2025. The purpose of this study is to determine if China’s ambition of reducing its carbon dioxide emissions is feasible. This investigation also examines the potential effects of China's emissions on the economic growth of other countries. The study demonstrates that China’s target may not only reduce her output, but may also adversely affect the economic growth of others. This article further reveals that unemployment in China is likely to soar during the reduction in emissions and energy consumption. Additionally, this paper evaluates the effects of green taxation on carbon dioxide emissions. In conclusion, there is a possibility that China may reach her emissions target by 2025. However, the country faces a dilemma between economic growth and environmental preservation. It is recommended that China should explore techniques which will reduce emissions but not impinge negatively on economic growth.

Portland cement production leads to significant carbon dioxide emission and greenhouse effect. Magnesium oxide eco-cement, which is a mixture of Portland cement, magnesium oxide and fly ash, may be an alternative production. In this paper, the issue is focused on the carbon dioxide absorption ability and mechanical performance of this eco-cement. Several mix proportions of eco-cement were designed to conduct forced carbonation, strength and expansion tests. Also, microstructure analysis after carbonation was conducted. The results indicate that magnesium oxide eco-cement can efficiently absorb carbon dioxide and carbonation can improve mechanical performance substantially, also expansion of the eco-cement is found to fall within the safe limits and possesses good stability and soundness.
