Iron and steel are the world's most recycled materials, and among the easiest materials to reprocess, as they can be separated magnetically from the waste stream. Recycling is via a steelworks: scrap is either remelted in an electric arc furnace (90-100% scrap), or used as part of the charge in a Basic Oxygen Furnace (around 25% scrap). [20]
Each tonne of scrap steel recycled saves 1.5 tonnes of CO 2, 1.4 tonnes of iron ore and 740 kg of coal. Steel is the world's most recycled material, with more than 85% of all the world's steel products being recycled at the end of their life: an estimated 630 million tonnes of steel scrap were recycled in 2017, saving 945 million tonnes of CO 2 ...
The metal cans were later recycled into steel reinforcement bars to be used in local construction projects. [31] The Stanolind Recycling Plant was in operation as early 1947. [32] Another early recycling mill was Waste Techniques, built in Conshohocken, Pennsylvania in 1972.
As of 2023, steel had one of the highest recycling rates of any material, with around 30% of the world's steel coming from recycled components. However, steel cannot be recycled endlessly, [ clarification needed ] and the recycling processes, using arc furnaces, use electricity.
Recycled scrap is a raw material feedstock for nearly 60% of steel made in the US, almost 50% of the copper and copper alloys produced in the US, more than 75% of the US paper industry's needs, and for 50% of US aluminum. Recycled scrap helps keep air and water cleaner by removing potentially hazardous materials and keeping them out of landfills.

As more steel is produced than is scrapped, the amount of recycled raw materials is about 40% of the total of steel produced – in 2016, 1,628,000,000 tonnes (1.602 × 10 9 long tons; 1.795 × 10 9 short tons) of crude steel was produced globally, with 630,000,000 tonnes (620,000,000 long tons; 690,000,000 short tons) recycled.
