Objectives During the last decade, coal-based sponge iron plants, a highly polluted industry, have grown rapidly in Barjora, India. Understanding their workers’ perception of health is essential in people-centered healthcare. The aim of the study was to assess their health-related quality-of-life (HRQoL), and to determine factors that independently predict their HRQoL.

Direct reduced iron Wikipedia

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting

Then in 1983, Odisha Sponge Iron Limited set up India’s second coal based DRI plant. The third coal based DRI plant was set up by Tatas in 1985based on their own technology. To push up further growth, DRI industry was de-licensed in 1985 baring certain location restrictions much before the de-licensing and deregulation of Indian economy in 1991.
