Investigation of dust exposure and control practices in the
Construction, agriculture, and mining are among the industries that contribute most to atmospheric dust levels. Excessive dust emissions cause health and industrial problems, e.g., health hazards, the risk of dust explosions and fire, damage to equipment, impaired visibility, unpleasant odors, and even problems in community relations.Construction industries consume a large part of the natural resources in the production of concrete. Utilization of the waste in concrete has gained interest due to the development in the construction structure and depletion of natural resources. This article reviews the utilization of dolomite industrial waste in sustainable concrete production. Potential of dolomite industrial waste as construction material

Achieving net zero greenhouse gas emissions in the cement industry
Challenges to achieving zero emissions in the cement industry stem in large part from the raw materials, such as limestone and crushed rock, that are widely available, and the well-established manufacturing technology used for cement production, which has been difficult to innovate. 11 While cement is just one constituent in products The identification of the dust characteristics in coal mine working faces is essential for preventing coal dust explosion and occupational diseases. In this paper, dust samples from the coal mines in southern Shanxi province and Henan province, central North China, were selected as the research objects. The results show that the dust contains primarily Characteristics of Dust in Coal Mines in Central North China

Industrial waste refers to the waste produced with the aid of industrial activity comprising of materials deemed useless in the production process of factories, mills, industries, and miningAbstract. The utilization of coal in the cement and concrete industries takes three basic forms: (1) as a fuel in the production of cement clinker; (2) ash produced by burning coal in power stations is used as a component in cement rotary kiln feeds; (3) ash produced by burning coal in power stations is used as a mineral additive in concreteCoal utilization in the cement and concrete industries

(PDF) Cement Manufacturing Process and Its Environmental
The cement industry is one of the major contributors to global greenhouse gas emissions, accounting for approximately 8% of total anthropogenic CO 2 emissions. Apart from CO 2 emissions, cementCement-based materials, such as concrete and mortars, are used in extremely large amounts. For instance, in 2009 concrete production was superior to 10 billion tons. Cement plays an important role in terms of economic and social relevance since it is fundamental to build and improve infrastructure.

Water is also needed for equipment maintenance and washing. can minimise the CO2 emissions produced by the cement industry. Cement plants all across the world have already embraced several of these methods. To reduce While conventional concrete is produced, if the WMP is replaced with sand, the changes in the amount of slumps in the fresh concrete will be bigger (Fig. 6.3A). These changes are less for the concrete produced by replacing with cement (Fig. 6.3B).

Nepal struggles to balance nature and industry Nepali Times
In the past eight years, the government has collected only Rs2.84 billion in royalty from cement industries. On the other hand, the yearly turnover from the industry, says Thapa, amounts to Rs150 billion. For example, Sarbottam Cement extracted 371,000 tonnes of limestone from its quarry in Palpa district in the fiscal year 2019/2020.
