Recycling processes used materials into new products to reduce waste and pollution. Common recyclable materials include glass, paper, metal, plastic, and electronics. While recycling provides benefits like reducing energy usage and greenhouse gas emissions, it also faces criticisms. Recycling is not always more energy efficient than producing goods from raw materials. It can use more energy for collection and transportation. Whether recycling saves energy depends on the specific material and process. Additionally, landfills are often a more economical waste disposal method when accounting for all costs of recycling programs. While recycling aims to help the environment, it may not provide as many benefits as commonly believed.
