Adani Group uses spray to control coal dust emission at its projects in Goa, Chhattisgarh, Talabira and more. Similarly, last year, MCL successfully tested a remotely-controlled nozzle with a spraying capacity, enough to deal with fire and suppress coal dust
Recently, at the Indo-US Partnership Vision Summit 2021, Union Minister Nitin Gadkari assured his co-panelists on how the Indian government has been taking steps to reduce around 30 to 35 per cent carbon emissions by 2030.
Speaking of which, while a lot of factors contribute to the country’s carbon emission, coal is one of the chief sources. In light of this, private companies like the Adani Group and MCL have been taking sustainability into consideration to boost India’s goal of reducing greenhouse gas emission.
Since coal dust causes various pulmonary diseases and is a major source of air and water pollution, Adani Group uses spray at its Goa project in Mormugao Port Terminal, where it is responsible for loading and unloading coal. However, with most coals being hydrophobic, they cannot be easily wetted by water.
Thus, the spray water is infused with wetting agents to capture dust more effectively and reduce its emission by over 80 per cent. With this, the group seeks to ensure the safety of workers as well as the nearby residents while reducing the environmental impact of coal dust.
Adani Group holds merely around 10 per cent share at MPT Goa, with JSW and Vedanta accounting for the lion’s share. Moreover, it has been handling several coal projects in Talabira, Chhattisgarh and more, on a relatively larger scale. These factors can also be attributed to how Adani Group has been able to ensure responsible coal handling at its Goa project so seamlessly and efficiently.
Similarly, taking the idea of coal dust suppression to another level, is Mahanadi Coalfields Limited. Following a series of technological innovations for making coal operations safer and more sustainable, the mining company launched a remotely-controlled ‘robotic nozzle’ last year. The system can be operated from distant and has the ability to spray mist over a large area – 360 degree horizontal pan and 180 degree vertical pitch.
With the increasing demand of energy, our dependency on fossil fuel continues. While meeting the energy demand is crucial, it is equally important to do it sustainably, for the environment and the health of the people. Thus, whether it is the Adani Group’s use of spray at its Goa project or MCL’s launch of robotic nozzle, such steps are definitely the need of the hour to reduce the country’s overall carbon emanating from coal.
