Recycling involves separating, collecting, processing, and reusing materials that would otherwise be thrown away. Common recyclable items include aluminum cans, plastic bottles, glass jars, newspapers, and cardboard. The recycling process is circular - collected materials are transported to a facility to be cleaned, sorted, and remanufactured into new products. Recycling provides benefits like lower raw material costs, reduced waste disposal costs, and decreased pollution and energy consumption compared to producing goods from virgin materials.
