Analysis of Resource Efficiency Management Indices through Industry Material Flow Analysis: Focusing on Manufacture of Fabricated Metal Products Industry

초록

This study introduces a methodology for material flow analysis tailored to the characteristics of each industry, conducts material flow analysis at the industry level, and analyzes resource efficiency management indices. The industry to be analyzed is the ‘Manufacture of fabricated metal products, except machinery and furniture.’ To conduct the material flow analysis, we first established categories for input resources and generated waste. We then set the system boundaries of the industry (the analysis boundary) to define the scope of input resources and outflow waste, thereby determining the level of material flow analysis. The scope of the input resources encompassed natural and processed resources, while material flow analysis focused on industrial waste. The material flow analysis revealed that the manufacture of fabricated metal products industry used a total of 30,345,570 tons/year of input resources while generating 239,729 tons/year of industrial waste. Additionally, material flow analysis of the generated waste indicated that 72.4% was recycled, 15.1% underwent interim treatment, such as incineration, and 12.5% was directly landfilled. Nearly all the recycled waste was material recycled, with 99.5% undergoing material recycling and 0.5% undergoing thermal recycling. The resource recycling rate for the analyzed industries was 48.6%, with a final disposal rate of 41.9%. The resource recycling rate and final disposal rate of the manufacture of fabricated metal products industry fall short of the targets outlined in the first Master Plans for Resources Circulation, indicating the need for measures to achieve these targets. © 2024, Korea Society of Waste Management.
