addition, it generates more than $10 billion in revenue for federal, state, and local governments. Scrap recycling also helps reduce greenhouse gas emissions and conserves energy and natural resources. For example, scrap recycling diverts 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 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.
