A scrap trading company is a business that specializes in the buying and selling of scrap materials, including metals, plastics, paper, and other recyclable items. These companies play a crucial role in the supply chain by sourcing waste materials from industries, construction sites, households, and other sources, processing them for reuse, and redistributing them to manufacturers and recycling facilities. Scrap trading companies help reduce landfill waste and promote sustainable resource management, as recycled materials can often be processed more economically and with less environmental impact than newly mined or manufactured resources.
