Recyclable resource

Name	Details
Mill scale	Iron oxide generated and collected in the process of rolling steel sheets, which is used as a material for steel powder, or sintered and reused as a material for manufacturing pig iron
Spent catalyst	Catalysts used for desulfurization of oil contain many metals, which is collected and recycled as a material for ferroalloys
