Value recovery is a research area that focuses on the process of recovering valuable materials from waste streams in order to create new products or generate economic value. This can include recovering materials such as metals, plastics, and chemicals from discarded products or industrial byproducts. The goal of value recovery research is to find innovative and sustainable ways to extract value from waste materials, reduce the environmental impact of waste disposal, and create economic opportunities for businesses and industries. This research area often involves the development of new technologies, processes, and business models that can transform waste into valuable resources.
