Management of Waste Generated in Steel Rerolling Industries of Nepal

Abstract

The study on nature and management of waste generated in iron & steel industries of Nepal provides an overview of the nature and type of waste generated and their current management practices. The purpose of the study was to identify the nature of waste generated in iron and steel industries of Nepal and recommend appropriate measures for its management. For this study, five iron & steel industries were visited to collect the data on the waste as well as monitor the air quality and collect the wastewater samples. The volume of solid waste, waste water and GHG emission was quantified. The analysis of wastewater samples showed that the tested effluent parameters were within the limit of national environmental standard. Similarly, the analysis of air samples showed that the TSP was high in most of the industries. Solid waste was found to be managed by recycling and reselling the waste products and dumping the waste in their own premises. But proper management of ash was not done. Majority of the industries had not installed ETP for proper wastewater management. The wastewater volume from all the industries was found be high. As for the emission management, no control measures were installed in the furnace. The overall waste management condition in the visited five steel rerolling industries was found to bebelow satisfactory. The study also provides industry specific as well as policy level recommendations for effective compliance for the standards and improve the environmental performance of the industries.
