Cement dust deposition on soil has been implicated in the heavy metal (HM) contamination of soil, leading to adverse effects on plants and humans. This study assessed the impact of cement dust deposition on the HM content of the soil samples in the vicinity of a cement factory and its implication on the public health of the host community. Topsoil samples were collected at varying distances and...
The globally growing demand of cement results in towering collection of kiln dust from cement plants. The disposal of this fine dust is very difficult and poses an environmental threat. To overcome this problem, research is being carried out in different parts of the world to find out economical and efficient ways and means of using cement kiln dust (CKD) in various applications like soil stabi...
Cement-based materials have often been used for infrastructure construction and repair. The production of conventional Portland cement is energy-consuming and environmentally unfriendly. For example, production of one ton of Portland cement generates approximately one ton of carbon dioxide (CO 2 ) from calcining limestone and fuel use. It is estimated that cement production contributes 7% of to...
Aerosols emitted by antropogenic activity are in relationship to their emission source and exhibit distinguishable characteristics (size, metal concentration and density) that can often univocally identify the source. Nevertheless, different processes can characterize industrial plants that produce the same product. Due to this, dusts emitted by the same source can have different chemical compo...
Considering increasing population growth in recent decades, and consequently, the increase in waste production in the world, waste management and efforts to reduce their harm to the environment has become an important issue. One of the appropriate ways to manage municipal waste is to generate energy from waste, especially by RDF production method. On the other hand, in order to reduce the consu...
Power-intensive processes can lower operating expenses when adjusting production planning according to time-dependent electricity pricing schemes. In this paper, we describe a deterministic MILP model that allows optimal production planning for continuous powerintensive processes. We emphasize the systematic modeling of operational transitions, that result from switching the operating modes of ...
Cement production is an industry that consumes a lot of electric energy. During the period power shortage in China, government encouraged multi-channel financing to run electricity alleviate problem large industrial users. Therefore, many cement enterprises have established their own plants. This paper analyses basic electrical characteristics industry, classifies loads enterprises, and studies...
This research paper aims to analyze and compare the key aspects of Shree Cement Birla Cement, two major players in Indian cement industry. The study provides an overview both companies, including their company profiles, production capacities, product portfolios, market presence, sustainability initiatives. explores capacities considering integrated plants geographical locations. It examines ran...
Production planning and inventory control efforts are known as the driving engines of manufacturing systems. The manufacturers, competing to survive in these days’ competitive business environment, aim to satisfy customers’ needs. This requires a precise production plan throughout the supply chain. These days, because of the increasing costs of production and distribution, especially in the cem...
BACKGROUND The evidence regarding the association between lung cancer and occupational exposure to cement is controversial. This study investigated causes of deaths from cancer of respiratory tract among cement workers. METHODS The deaths of the Greek Cement Workers Compensation Scheme were analyzed covering the period 1969-1998. All respiratory, lung, laryngeal and urinary bladder cancer pro...
