What are the environmental, human health, social and economic implications of using alternative energy sources in cement manufacturing? How does the use of alternative energy sources in cement manufacturing compare with other endoflife/waste management options in terms of the net environmental, human health, social and economic aspects?
ALTERNATIVE RAW MATERIAL SOURCES FOR CEMENT PRODUCTION. Cement is a complete mixture of mineral substances that gradually harden when mixed with water. It is the product of the reaction of lime with the oxides of silica alumina and iron. It is used in the construction of industry as a blending material.
In 2014, the General Organization for Standardization and Quality has issued a set of new standards related to the use of coal as one of the main alternative sources of energy in cement factories, which included the use of coal only for the cement industry.
The Clean Energy Manufacturing Initiative (CEMI) is a few years old now, but its mission is ongoing: to rally talent from across the industry to design and deploy more efficient technologies and find less wasteful ways to meet consumer material demands.. Renewable energy is the future of the manufacturing industry and CEMI is just one of many institutions helping get there.
Energy sources used as feedstocks. Some manufacturers use energy sources as feedstocks—raw materials—in their manufacturing processes. (Manufacturers are a subset of the industrial sector, which includes manufacturing, agriculture, construction, forestry, and mining.) For example, HGLs are feedstocks for making plastics and chemicals.
Siam Cement Group Biomass to Energy Increasing the sustainability of Thailand''s cement sector By shifting to renewable biomass instead of fossil fuels, five Thai cement manufacturing plants can substantially reduce their carbon emissions – leading to environmental and socioeconomic benefits for surrounding communities.

Hima Cement Uganda looks at Alternative Energy to Save Costs. Hima Cement, is looking to use alternative sources of energy to power its manufacturing plant in Uganda. The cement firm is a subsidiary of Kenya''s Bamburi Cement and a member of multinational Lafarge Group.
Alternative fuels are another source of energy used by cement producers around the world. They can replace the basic sources of energy used by cement kilns to produce the high temperatures that ...
development (RD) necessary to develop new cement manufacturing processes. Pyroprocessing is ideally suited to utilizing biomass and other nontraditional alternative fuel sources. Its extremely high operating temperature and long residence time ensure complete combustion of these fuel sources.
The objective of this paper is to review the current status of the cleaner cement manufacturing, the cement industry''s shifting to alternative raw materials and alternative energy sources, and the modelling of the thermochemical processes inside the cement combustion units. Additionally, some critical issues, which up to now have not been ...
UltraTech Cement Limited, the largest manufacturer of grey cement, white cement and readymix concrete in India, said it plans to increase the contribution of green energy to 25 per cent of its total power consumption by 2021. More than 10% of the total power will come from renewable energy sources, it added.
This report address two questions: What are the environmental, social and economic impacts of using alternative fuels compared with conventional fuels in cement manufacturing? How does the use of alternatives in cement manufacturing compare with other possible endoflife options like recycling or disposal in landfills? Systematic reviews collate, analyze and synthesize the body evidence from ...
Nov 18, 2010· Cement production process. Cement is considered one of the most important building materials around the world. In 1995 the world production of cement was about 1420 million tonnes (Cembureau, 1997).Cement production is an energyintensive process consuming thermal energy of the order of GJ/tonne of clinker produced, which accounts for 30 – 40 percent of .
Alternative Energy in Cement Manufacturing With increasing urbanization, cement serves quite literally as the foundation of the building boom. Cement is .
Jan 15, 2020· In 2018, coal accounted for just 16% of total domestic energy production, less than half its share a decade earlier. The amount mined in the first nine months of 2019, 540 million tons, was about a third lower than in the same period in 2009. Over the past decade, solar power has experienced the largest percentage growth of any energy source.
Nov 22, 2019· Topics solar energy renewable energy Concrete carbon emissions carbon WIRED is where tomorrow is realized. It is the essential source of information and ideas that make sense of .
Cement manufacturing requires sustained high temperatures in excess of 1,450°C, typically provided by costeffective gas, oil, coal and coke. Nonetheless, energy represents 20% to 40% of the total cost of cement production on average, pressing the industry to find less expensive energy sources.
Nov 10, 2016· 7. Types of alternative energy sources Use of the power (electricity) from renewable energy sources. The power use in cement plants takes place dominantly in raw material preparation, grinding, homogenization and in cement finish grinding. In kilns, the biggest electricity consumers are the drives of rotary kilns.
Renewable energy industry primed for continued growth. For the first time ever, in April 2019, renewable energy outpaced coal by providing 23 percent of US power generation, compared to coal''s 20 percent share. 1 In the first half of 2019, wind and solar together accounted for approximately 50 percent of total US renewable electricity generation, displacing hydroelectric power''s dominance.
For energyintensive industries, biomass will be a crucial renewable energy source to meet hightemperature heat demand. IRENA released this manufacturing roadmap in June 2014, along with the full report on the REmap 2030 analysis. In March of 2015, IRENA released a background paper for the renewable energy in manufacturing report.
