The term "scrap metal" refers to any discarded or unwanted metallic material that can be recycled for reuse. This includes a wide variety of materials such as steel, copper, aluminum, brass and more. Scrap metal is often collected from construction sites, demolition projects, manufacturing facilities, and other sources where it has been discarded or no longer needed. It is then processed and melted down to create new products, reducing waste and conserving resources. The term "scrap" can also refer to the value of this metal, which fluctuates based on market demand and availability.
