Environmental Benefits of Commercial Recycling for Metal

Why Recycle?

A wide range of metals including aluminium, copper, steel and iron can be recycled. Making products from recycled metals uses less energy, reduces carbon emissions, and uses less water compared with using raw materials. Commercial recyclers and scrap metal yards will buy scrap metal at the market price, making this a valuable resource to recycle. Metals such as lead and mercury are classified as hazardous materials and must be disposed of through approved facilities. If placed in landfill, heavy metals can leach and contaminate the soil and water system.

Victoria recycles around 1 million tonnes of commercial metal per year1. That's the equivalent "everyday" greenhouse gas savings of driving a car over 8 billion km or driving around the equator 214 thousand times.
