Scrap metal recycling is a vital economic activity, with both its philosophy and practice aimed at resource conservation and environmental protection. It involves the collection and processing of waste materials, and is an integral part of the circular economy.

Scrap metal recycling refers to the process of reclaiming and utilizing discarded steel structural materials from construction projects, civil scrap iron, industrial scrap iron, and other scrap metals. Scrap metal recycling is a strategic development for a circular economy, which can conserve resources, reduce transportation costs, minimize waste, and also alleviate environmental pollution. Not only does scrap metal recycling save on resource and material costs, but it also accelerates the renewal of industrial structures and enhances the efficiency and overall benefits of the industrial chain.
