What is metal recycling?
Metal recycling is the process of reusing old metal material, mainly aluminum and steel, to make new products. Recycling old metal products uses 95% less energy than manufacturing it from new materials. Aluminum is an ore, which is a mineral, and it usually exists by combining with oxygen. To make an aluminum product an electrical current is run through the metal and separates the oxygen from the aluminum. The aluminum is then melted and shaped into various products. Steel is created in a chemical reaction process located in a hot blast furnace. During this process the iron ore is freed from the oxygen and is then used to make steel. Both of these metal recycling processes consume millions of tons of energy. If we recycle metal products we only have to use 4% of this total energy, which can save our natural resources and reduce our greenhouse gas emissions. What types of metal products can be recycled? Almost all aluminum and steel products can be recycled over again without compromisi
