Managing waste in an environmentally friendly, socially responsible, and techno-commercially viable manner is of crucial importance in the steel manufacturing process. JSW Steel has an integrated strategy towards efficient waste management that ensures optimal utilization of resources and minimal disposal of solid waste.
Solid wastes in steel plants are essential by-products generated during various processing steps involved in the production of iron and steel. Solid wastes generated by integrated iron and steel works cause environmental pollution and therefore must be discarded.
With the waste plastic import control introduced in China, the volume of material being recycled has dropped, leading to an increase in landfill waste disposal. As a result, the factory waste recycling rate in fiscal 2024 was 99.3 %, achieving the 99% target in our GPI 2024. We will introduce more activities which aim to maintain and improve ...
Ship hazardous waste using a registered transporter to a hazardous waste TSDF for treatment and disposal. Adjust process to reduce solvent use (e.g., use compressed air to blow out residual alkaline solution after removing from boil-out tank, then collect and return to tank). Employ lead-free or reduced lead solder.
Iron and steel manufacturing; Water treatment; ... such as scraps and residuals that result from the production process. Secondary waste are the materials that are generated as a result of the handling, storage, or treatment of primary waste. ... A certified waste disposal company can assist you with declassifying your industrial …
Solid waste management in steel industry is broadly classified in "4 Rs" i.e. reduce, reuse, recycle and restore the materials. Reuse and recycling the entire solid waste generated in the process of steel making is a viable solution in targeting a clean, green and zero waste technology leading to sustainable development of the steel industry.
Segregating different waste streams, e.g., keeping copper-related waste separate from aluminum or steel or keeping polymer or poor conductor waste separate, can improve the value of waste. Poor waste management could cost 0.5%-2% of top-line sales value, which comes straight off the bottom-line profit. How can material waste be minimized?
