Scrap metal is bits and pieces of metal parts (e.g.,) bars,
turnings, rods, sheets, wire) or metal pieces that may be combined
together with bolts or soldering (e.g., radiators, scrap
automobiles, railroad box cars), which when worn or superfluous can
be recycled.
scrap metal, used
metals that are an important source of industrial metals and
alloys, particularly in the production of steel, copper, lead,
aluminum, and zinc. Smaller amounts of tin, nickel,
magnesium, and precious metals are also recovered from
scrap.
Scrap consists of recyclable
materials, usually metals, left over from product manufacturing and
consumption, such as parts of vehicles, building supplies, and
surplus materials. Unlike waste, scrap has monetary value,
especially recovered metals, and non-metallic materials are also
recovered for recycling.
