secondary raw materials

Secondary raw materials are materials recovered from waste products or used items, rather than extracted directly from natural sources. They can be recycled, reused, or processed to serve as inputs in manufacturing, reducing the need for virgin resources. Examples include recycled metals from old appliances, paper from used newspapers, or plastic collected from waste bottles. Using secondary raw materials helps conserve natural resources, decrease environmental impact, and promote sustainable production practices. Essentially, they are valuable resources obtained from waste, giving materials a second life in the economy.
