The National Waste & Recycling Association (NWRA) is a Washington, D.C.–based trade association that represents private waste and recycling companies, as well as manufacturers and distributors of equipment that processes the material, and service providers who serve those businesses. Its nearly 700 members are a mix of publicly traded and ...
To supply its mills, Nucor uses electric arc furnaces and continuous casting to melt scrap steel as opposed to blast furnaces to melt iron.In 2023, the company produced and sold approximately 18.5 million tons of steel and recycled 18.4 million tons of scrap.
Its maximum output of 120,000 tons per year was approximately half of the entire U.S. copper output from recycled copper. The company website described Chemetco as one of the world's largest copper refiners and reported an estimated revenue in 1999 of $500 m. [1] It was listed in 2000 as the 23rd-largest privately held company in the United States.
] Scrap recycling also helps reduce greenhouse gas emissions and conserves energy and natural resources. For example, scrap recycling diverts 135 million short tons (121,000,000 long tons; 122,000,000 t) of materials away from landfills. Recycled scrap is a raw material feedstock for nearly 60% of steel made in the US, almost 50% of the copper ...
The circuit boards contain such precious metals as gold, silver, platinum, etc. and such base metals as copper, iron, aluminum, etc. One way e-waste is processed is by melting circuit boards, burning cable sheathing to recover copper wire and open- pit acid leaching for separating metals of value.

In the US, more copper is recovered and put back into service from recycled material than is derived from newly mined ore. Copper's recycle value is so great that premium-grade scrap normally has at least 95% of the value of primary metal from newly mined ore. [80] In Europe, about 50% of copper demand comes from recycling (as of 2016). [81]
The metallic combinations are engineered to provide the benefits of two disparate materials. CCS, or copper-clad steel wire, provides the strength of steel with the conductivity of copper. In 1963, the original molten-weld process for Copperweld® CCS wire was abandoned in favor of a pressure-rolling process, which is still used today. In the ...
