JSW Steel Vijayanagar Works, one of the major steel makers in India, has launched a steel slag sand making plant, to mark the World Environment Day recently. JSW has said that the plant, which will produce sand from steel slag, has an installed capacity of 0.30 Mtpa [million tonnes per annum].
As per a media note issued by the company, the commissioned unit is equipped with value-added technology, which will not only mitigate the slag disposal problem in the plant but also provide low-cost eco-friendly sand for construction purposes.
“The Research & Development team of JSW Steel Vijayanagar Works has developed this sustainable process for converting steel making slag into sand (fine aggregate to replace river sand) for its extensive usage in civil construction. This new steel slag sand also offers an eco-friendly alternative to river sand. This patented process circuit treats crushed slag through a vertical shaft impactor and a classifier after metallic separation,” the JSW said.
After inaugurating the plant, Ballari Deputy Commissioner Pavan Kumar Malapati said that the new technology adopted in the plant will help address issues related to sand shortage in the State and appreciated JSW for its environment-friendly initiatives.
“Such initiatives play a pivotal role in the sustainable use of environment that will lead to sustainable growth,” Mr. Malapati said.
Highlighting the various JSW initiatives in solid and liquid waste management taken up at Vijayanagar Works, JSW Steel Vijayanagar Works president P.K. Murugan said that steel slag sand will be an economically viable and environmentally acceptable alternative material for replacing river sand and manufactured sand used in road and civil constructions.
“The use of slag as aggregate reduces the need for virgin material, energy and polluting emissions generated during the mining/crushing, processing and transportation of that material. Effective utilisation of this material will have a tremendous economic impact, conservation of natural resources and gainful recycling of process by-products,” he said.

“Writing, in general, is a very solitary process,” says Yauvanika Chopra, Associate Director at The New India Foundation (NIF), which, earlier this year, announced the 12th edition of its NIF Book Fellowships for research and scholarship about Indian history after Independence. While authors, in general, are built for it, it can still get very lonely, says Chopra, pointing out that the fellowship’s community support is as valuable as the monetary benefits it offers. “There is a solid community of NIF fellows, trustees, language experts, jury members, all of whom are incredibly competent,” she says. “They really help make authors feel supported from manuscript to publication, so you never feel like you’re struggling through isolation.”

Supreme Court ruling on socialism, secularism
Several principals of government and private schools in Delhi on Tuesday said the Directorate of Education (DoE) circular from a day earlier, directing schools to conduct classes in ‘hybrid’ mode, had caused confusion regarding day-to-day operations as they did not know how many students would return to school from Wednesday and how would teachers instruct in two modes — online and in person — at once. The DoE circular on Monday had also stated that the option to “exercise online mode of education, wherever available, shall vest with the students and their guardians”. Several schoolteachers also expressed confusion regarding the DoE order. A government schoolteacher said he was unsure of how to cope with the resumption of physical classes, given that the order directing government offices to ensure that 50% of the employees work from home is still in place. On Monday, the Commission for Air Quality Management in the National Capital Region and Adjoining Areas (CAQM) had, on the orders of the Supreme Court, directed schools in Delhi-NCR to shift classes to the hybrid mode, following which the DoE had issued the circular. The court had urged the Centre’s pollution watchdog to consider restarting physical classes due to many students missing out on the mid-day meals and lacking the necessary means to attend classes online. The CAQM had, on November 20, asked schools in Delhi-NCR to shift to the online mode of teaching.
