Limestone Mining And Greenhouse Effects

Among various energy sources, coal is a crucial resource, most abundantly present, and is also the cheapest source of energy. The continuous increases in global energy demand lead to subsequent increases in emissions of carbon dioxide (CO 2), methane, aerosols, and other air pollutants in the environment.Controlling the air pollutants including greenhouse …

As the demand for cement supply is continually growing, this causes an increase in the use of aggregate, especially limestone since it is important in the production of Portland cement [13], [14].Exhaustion of the earth's non-renewable resources is a growing dilemma when the reason is that the energy consumption has rapidly increased during the 21st century [15].

Here's how it works: Cement is made by grinding up limestone and then heating it, along with clay or shale, in a kiln. The temperature of the kiln ranges from 2,700 – 3,000 degrees Fahrenheit. During this process, CO2 is released in two ways: 1) from the fossil fuels used to heat the kiln and 2) from gases released from the limestone itself.

The oceans comprise large natural carbon sinks, having already absorbed around 26% of the anthropogenic (excess) CO 2 emissions (Figuerola et al., 2021).However, this absorbed CO 2 has resulted in ca. 0.1 drop in the natural alkalinity of the surface ocean water (from 8.2 to 8.1 (Paquay and Zeebe, 2013)), which translates to ca. 30% increase in acidity …

According to the effect of limestone mining in the region, it is proposed that all stakeholders, in particular the owners of mines and cement plants, should pay the requisite attention to the environmental issues prevailing throughout the area. It leads to perform the necessary actions to maintain the ecosystem environmental clearness ...

This chapter discusses the concepts of CO 2 emission, global warming, and climate change with an emphasis on their environmental impacts. Specifically, the chapter reviews different sources of atmospheric CO 2 emissions and recent advances in the implementation of carbon capture and storage (CCS) technology to mitigate greenhouse gas emissions. In this …

Introduction. The increases in average air and ocean temperatures and sea levels have become unequivocal signs of global warming [].Global warming is primarily caused by an increase in atmospheric greenhouse gas concentrations, carbon dioxide (CO 2) being the most significant greenhouse gas.The greenhouse gas effect occurs when the concentration of …

Carbon dioxide, or CO2, is the main greenhouse gas released through cement production, significantly impacting global warming by contributing to 7-8% of global carbon emissions. To put this in perspective, it's roughly equivalent to the CO2 emissions from all the …

Regarding to the four damage categories, `resources' and `climate change' categories were the two greatest environmental impacts of the limestone rock production. Diesel fuel and electricity …

The study was expected to provide a robust reference system for future investigations on the environmental effects of limestone mining and cement production using integrated …

Assessment of Environmental Impacts of Limestone Quarrying Operations in Thailand Suthirat KITTIPONGVISES1–3* 1Environmental Research Institute, Chulalongkorn University (ERIC), Bangkok 10330, Thailand 2Research Program of Toxic Substance Management in …

Limestone has always been widely used in various sectors, thus having significant economic and environmental impacts. The quarrying process is, on the one hand, essential, but on the other, …

Experimental evaluation of limestone-hydrogen reactions and the attendant effects on underground hydrogen storage are rarely reported in literature due to the difficulties of conducting such experiments. In this study, limestone cores were prepared and pressurized with H 2 for 125 days at 75 °C and 1400 psi. The core samples were then scanned ...

Presently, there is widespread global interest in the area of mining and its sustainability that focused on the need to shift mining industry to a more sustainable framework. The aim of this study was to systematically assess all possible environmental and climate change related impacts of the limestone quarrying operation in Thailand.

Construction has begun in San Antonio on what will be the world's first commercial plant in which carbon dioxide captured from the air will be mineralized into baking soda.

Mining is necessary for the production of energy and materials that drive the world's economy (Hund et al., 2013).One major consequence of mining is biodiversity loss (Sonter et al., 2018) and land degradation, particularly in tropical regions (Sonter et al., 2017), where mining for coal, limestone, precious metals, and rare-earth elements is a major activity (Caballero Espejo …

Water from abandoned coal mines contains high levels of carbon dioxide and methane. Mine water as a source of GHGs, needs recognition in greenhouse gas budgets. …

Over millions of years, carbon dioxide, a greenhouse gas in the atmosphere, becomes sequestered in rocks like limestone and fossilized plants that may become coal and other fossil fuels. The carbon is taken out of the faster pattern of carbon cycle processes and is thus sometimes called the slow carbon cycle. ... so new species can have a new ...

indicators · Lithological vulnerabilities · Limestone mining · Cement producing environment Introduction Many of the raw materials used in producing cement, such as limestone, gypsum, chalk, shale, clay, and sand, are mined from the earth (Albeanu et al., 2004), and this justifies why most cement plants are situ-ated near a limestone deposit.

fertilizers, which are energy-intensive to produce and contribute to greenhouse gas emissions [13]. Limestone mining co-products, being byproducts of an existing industry, present an environmentally friendly alternative. They oer a way to recycle waste material, reduce the carbon footprint of agriculture, and promote circular economy principles ...

The room and pillar method of mining is used to recover flat lying limestone deposits in the Eastern and Midwestern United States. The ... have been developed to alleviate the effects of horizontal stress in limestone mines include the selection of a stable roof line, favorable orientation of mine workings relative to the stress field, pillar ...

Deforestation Effects On Greenhouse Gases Emissions and Climate Change. ... Deforestation is tightly linked to the problems of urbanization, mining, and expanding agricultural land. The loss of tropical forests is the most visible regarding climate impact, and it can be traced back to the following factors: ...

The findings reveal that effective integration of green mining technologies leads to significant reductions in greenhouse gas emissions, lower energy consumption, and improved …

drainage originating from the coal and ore mining processes in general and open-pit mining in particular are well documented in the literature (Cherry et al. 2001; Skousen et al. 2002). Even though the environmental impacts of ore and coal mining have been adequately investigated, the impact of limestone rock mining has not been well studied.

The mining industry has significantly contributed to national economic development by supplying raw materials, offering employment opportunities, and spurring regional economic growth (Litvinenko, 2019).However, it has induced varying degrees of ecological damage in the vicinity of mining sites, such as vegetation destruction, soil erosion, atmospheric and water …

As the important mineral component of its cement, limestone will soon be mined from a new deposit by aggregates and construction materials company AfriSam's Ulco cement plant, in the Northern Cape.

One strategy for restoring degraded soils by opencast mining in semiarid regions is the application of organic amendments. However, selecting an appropriate organic amendment that improves soil quality and functionality for recovery in the short-term without a high contribution to increased CO₂ emissions is important for improving restoration strategies.
