Steel is the most suitable material for recycling. It is an iron-based alloy that is widely used in construction, transportation, and various industrial applications. Steel is 100% recyclable, and it can be reused over and over again without any loss in quality. It is also the most recycled material per ton globally, with 70 million tons of household steel scrap being used in the production of new steel every year. Recycling steel has many benefits, including reducing energy consumption and greenhouse gas emissions, conserving natural resources, and reducing waste sent to landfills. Therefore, steel is considered the most suitable material for recycling.
