# JSW Steel > JSW Steel has a specific route from steelmaking residual to infrastructure application: its FY2024-25 report describes a steel-slag road at Dolvi developed with CRRI. That is a useful signal, but it is not a universal slag-use claim. The next decision is one plant, slag chemistry and end use, with leachability, grading, processing, product standards and receiving-market evidence in the same record. - Industry: Metals & Mining - Collection: Active - Regions: Asia - Countries: India - Materials: Cement, Minerals, Steel, Water - Processes: Sorting - Evidence through: 2026-09-18 - Canonical URL: https://www.materialtransition.com/library/jsw-steel ## Material inputs to resolve Integrated steelmaking, scrap, slag, water systems and responsible steel supply JSW Steel's FY2024-25 Integrated Report states that nearly 100% of waste generated was utilised, all operational sites maintained Zero Liquid Discharge, and specific water consumption was 2.35 cubic metres per tonne of crude steel against a 2030 target of 2.21. The report also describes a steel-slag road at Dolvi and ResponsibleSteel certification covering more than 80% of primary steel production in India. Public reporting does not establish one site-level mass balance tying slag, water, steel output, product grade and downstream buyer evidence together. **34.2 MTPA** Domestic crude-steel capacity in the FY2024–25 report, including 1.7 MTPA under commissioning at that reporting date **2.35 m³/tcs** FY2025 specific water consumption **2.21 m³/tcs** 2030 specific water consumption target **Nearly 100%** Waste utilisation reported for FY2024-25 - Iron ore, coal, scrap, limestone, dolomite, alloys, refractories, water and energy - Sinter, coke, hot metal, steelmaking and rolling inputs - Slag, dust, mill scale, wastewater and other process residuals to characterize; the cited sources do not establish external availability ### Outputs and residuals to resolve - Flat and long steel products, downstream components and customer-specific grades - Steel slag, dust, sludge, mill scale, wastewater and emissions - Stream-level quality, destination, avoided virgin input and product allocation remain open **First decision:** Choose one JSW Steel plant and one stream, starting with slag or water. Map origin, process, quality gate, reuse route, product output and destination evidence. ## Scale signal JSW Steel's FY2024–25 Integrated Report lists 34.2 MTPA of domestic crude-steel capacity, including 1.7 MTPA under commissioning at the reporting date. This is not a current-capacity or production figure. FY2024–25 Integrated Report [4] #### Water signal The FY2024-25 report states 2.35 cubic metres per tonne of crude steel and a 2030 target of 2.21. #### Circularity signal JSW reports nearly 100% waste utilisation and describes a steel-slag road at Dolvi developed with CRRI, which still requires stream-specific qualification. #### Certification signal The FY2024-25 report says more than 80% of primary steel production in India came from ResponsibleSteel-certified sites. ### Decision boundary The public record supports one bounded next move: Choose one JSW Steel plant and one stream, starting with slag or water. Map origin, process, quality gate, reuse route, product output and destination evidence. It does not establish a buyer, commercial approval or supply agreement. ## Material flow map | Material or stream | Qualification gate | Process or destination | Evidence still needed | |-|-|-|-| | Steel slag | Chemistry, expansion, leachability and consistency | Road, cement or aggregate use | Lot, test, route and buyer specification | | Wastewater | Quality, treatment, reuse and discharge boundary | Cooling, process or horticulture reuse | Volume, quality, reuse point and ZLD record | | Scrap and mill scale | Grade, contamination, sorting and yield | Steelmaking or external recovery | Source, preparation, melt yield and output grade | This is a public screening map. It separates company-disclosed flows from open qualification work. It does not convert a destination into a buyer or an announced ambition into operating capacity. ## Three defensible entry lanes #### Turn slag utilisation into a product record A reuse percentage becomes durable when the output clears a specification and replaces a defined virgin material. **Next evidence:** Select plant, slag lot, test protocol, product, buyer and avoided aggregate or clinker. #### Make Zero Liquid Discharge measurable ZLD is a system boundary. The decision needs the water stream, treatment step, reuse point and quality. **Next evidence:** Select plant, process, baseline, treatment, reuse, residuals and watershed context. #### Join scrap to grade economics Scrap is not interchangeable. Chemistry, contamination and melt yield determine its value. **Next evidence:** Select scrap source, preparation, furnace, grade, yield and customer requirement. ## Evidence register - **Integrated Annual Report FY2024-25** JSW Steel, official investor sustainability page https://group.jsw.in/investors/steel/jsw-steel-investor-information-sustainability-reports [1] - **Integrated Annual Report FY2024-25 PDF** JSW Steel, official report PDF https://www.jsw.in/wp-content/uploads/2025/09/Integrated-Annual-Report-FY-2024-25.pdf [2] - **Sustainability initiatives** JSW Group, official sustainability page https://www.jsw.in/sustainability/ [3] Source hierarchy: filings and company disclosures first. The brief states what those sources support and leaves the unresolved plant, grade, permit, buyer and mass-balance questions explicit. ## Material Transition editorial interpretation The FY2024–25 report describes group-level waste-utilization and Zero Liquid Discharge disclosures, alongside a Dolvi steel-slag road project. These disclosures do not establish a site-level mass balance or general external material availability; site and stream evidence must be assessed separately. ## Sources - [1] Integrated Annual Report FY2024-25 - https://group.jsw.in/investors/steel/jsw-steel-investor-information-sustainability-reports - [2] Integrated Annual Report FY2024-25 PDF - https://www.jsw.in/wp-content/uploads/2025/09/Integrated-Annual-Report-FY-2024-25.pdf - [3] Sustainability initiatives - https://www.jsw.in/sustainability/ - [4] JSW Steel Integrated Annual Report FY2024–25 - https://www.jsw.in/wp-content/uploads/2025/09/Integrated-Annual-Report-FY-2024-25.pdf - FY2024–25 report's domestic crude-steel capacity figure, including capacity under commissioning at that reporting date. It is a dated capacity figure, not current capacity or production. Other water targets must retain their exact reporting-period and metric definitions.
