JSW Steel to make sand from slag
07 Jun 2022
JSW Steel has commissioned a 0.30
million tonne one-of-its-kind ‘Steel-Slag Sand’ plant at Vijayanagar Works in
Karnataka on World Environment Day.
The plant
will mitigate the slag disposal problem and 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 (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.
Pavan Kumar Malapati, IAS, Deputy Commissioner, Ballari, the new technology
will address the issues related to the sand shortage in Karnataka.
He
stressed the importance of the role that corporates and communities will play
to ensure that the conservation and sustainable use of the environment will
lead to sustainable growth and help uplift people and the surroundings at
large.
PK
Murugan, President, JSW Steel Vijayanagar Works, said the steel slag sand will
be an economically viable and environmentally acceptable alternative material
for replacing ‘River-sand’ and ‘Manufactured-sand’ used in roads 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.
