Recycling is the process of making new products from used materials. It has been practiced for thousands of years but became more widespread during times of war and economic hardship. Recycling is important because it conserves natural resources, saves energy, reduces pollution, and creates jobs. Common recyclable items include paper, glass, aluminum, steel, and some plastics. Recycling these materials helps reduce the need for raw materials and energy in manufacturing. Proper recycling reduces waste in landfills and pollution in the environment.
