Material recycling is the process of collecting and processing materials that would otherwise be discarded as waste. This involves sorting, cleaning, and reprocessing materials like paper, plastic, glass, and metal so they can be used to create new products. Recycling helps reduce the amount of waste sent to landfills and conserves natural resources. By recycling materials, we can save energy and reduce pollution associated with manufacturing new products. For example, recycling aluminum saves up to 95% of the energy needed to produce new aluminum from raw materials. Overall, material recycling plays a crucial role in promoting sustainability and protecting the environment.
