Waste recycling is the process of converting waste materials into new products to prevent waste of potentially useful materials, reduce energy usage, and decrease greenhouse gas emissions. This research area focuses on developing and implementing methods and technologies for efficiently collecting, sorting, processing, and reusing or repurposing different types of waste materials such as plastics, paper, metals, glass, and organic waste. Waste recycling plays a critical role in sustainable waste management and resource conservation by promoting a circular economy and reducing the environmental impact of waste disposal. Researchers in this field explore innovative solutions to improve waste recycling practices, increase recycling rates, and develop sustainable waste management strategies.
