 This research paper examines the potential of recycled materials from end-of-life vehicles to create new products. It found that four types of products, interlocking, clay, lightweight-swelled ceramic, LSE, and asphalt-paving aggregate, APA, can be made from melted slag from end-of-life vehicles. These products are all environmentally friendly and meet quality standards. Additionally, the research predicts that these products will have high market value and will be widely accepted due to their sustainable nature.
