Investigating Constraints in Steel Recycling by Nations
Ichiro Daigo and associates have produced an interesting paper in a recent issue of Resources, Recycling and Conservation which I believe is open access. Here is a copy of the abstract: - "To promote sustainable iron and steel production and consumption, maximizing scrap utilization is crucial. However, the restrictions and their impacts on promoting steel recycling are unclear. This paper aims to develop a methodology to identify main factors hindering steel recycling promotion in various countries. We developed a methodology based on material flow analysis and multiregional input-output analysis to quantify the impacts of restrictions from scrap unavailability and contamination, portfolio of steelmaking facilities, and demand for high-quality steel on promoting steel recycling. Results revealed significant variation in steel recycling perfor mance across 25 countries, with recycling input rates ranging from 8 % to 99 %, primarily restricted by the demand for high-grade steel in 20 countries. Our findings highlight the diverse challenges and opportunities for promoting steel recycling across countries, through promoting scrap recovery, constructing new infrastructure for Electric Arc Furnaces (EAFs), and upgrading the EAFs to produce flat steel products exclusively with scrap."
