In recent years, there has been increased public awareness on the need to protect the natural environment. People in developed economies like Australia now want their homes, businesses and industries to adopt strategies that can help utilise natural resources in an eco-friendly manner. Scrap metal recycling is one such strategy. It involves the recycling of old metal items so they can be given a new lease of life. Scrap metal recyclers purchase old metal from individuals, businesses or dealers, recycle it and then use it to make new products.
