Ways to make better use of scrap

Limiting global warming requires greatly reduced CO₂ emissions. The steel sector accounts for around 7 percent of energy-related emissions and is difficult to decarbonize. Recycling is particularly effective here, as steel production from scrap causes significantly fewer emissions than primary production. In addition to new technologies such as hydrogen-based direct reduction, a higher recycling input rate is key. The study "Methodology development for estimating the impact of restriction factors to promote national steel recycling" by Japanese scientists aims to develop a methodology that makes it possible to identify the main barriers to the promotion of steel recycling in different countries and to determine their quantitative effects.
