Air Pollution Monitoring Using WSN in Cement Factory

Abstract

Industrial revolution has started to rule the world in all aspects. As a result of this, pollutant level of contagious gas in the atmosphere is increasing at an alarming rate. The pollutants in the atmosphere create imbalance in ecosystem which in turn affects the health of human population. Although there existmany methodologies to check the pollutant level in atmosphere, it still remains a challenge for certain cement factories and chemical industries to keep a check on it. Such imbalances can be controlled by using appropriate air pollution monitoring system. OPSIS, Uras26, Magnos27 and CODEL are the methods which exist in cement factories to check the pollutant level during the emission from chimney only. Wireless Sensor Network is a versatile technology that can sense, monitor, measure, and gather information. The decision can be made from the collected information. This paper proposes how sensor nodes are deployed in cement factories at various stages of manufacturing process, how the pollutant is measured and conveyed to authority through a communication medium.

Green cement production in India: prioritization and alleviation of barriers using the best–worst method

“…Especially the air is the most fragile environment component because it has a low capacity of neutralising pollutants that are caused by the industrial activities and can react with other chemical substances from the atmosphere, producing new substances that are dangerous for the environment and for human health (Holban et al 2017). Given that the pollutant level of contagious gas in the atmosphere is increasing at an alarming rate (Anitha et al 2018), several international legally binding environmental agreements have been formulated between countries in a bid to curb the increase in the harmful effects of industrial activity on nature and man (Emetere and Dania 2019). These include the Montreal Protocol on ozone protection, UN Framework convention on climate change, International Environment Protection act of 1983, and London's clean air act of 1956.…”

“…However, the literature reveals that environmentally conscious initiatives and production methods very usually face barriers across a variety of aspects, which have well been documented in past research. The cement industry seems to be no exception as Anitha et al (2018) note that controlling pollution level in atmosphere still remains a challenge for certain cement factories, while note that although the cement industry of India is amongst the most efficient in the world, it still faces many obstacles in further developing emission reduction strategies. They also note that there are only very few studies focusing on the investigation of these barriers in the context of developing countries such as India.…”
