Recycling involves processing used materials into new products to prevent waste and reduce environmental impacts. Recyclable materials include glass, paper, metal, plastic, textiles, and electronics. Materials are collected and sorted, then cleaned and reprocessed for use in manufacturing. While recycling programs have economic and environmental benefits, short-term costs sometimes outweigh returns, though long-term recycling is more cost-effective and helps conserve resources and energy. Individuals can help support recycling programs.
