Resource recovery refers to the process of recovering valuable materials or energy from waste streams or byproducts of industrial processes. This can include recycling, composting, anaerobic digestion, and other methods to extract useful resources from waste materials. Resource recovery is important for sustainability and environmental protection, as it reduces the amount of waste sent to landfills and conserves valuable resources. It can also help to reduce greenhouse gas emissions and lessen the need for new raw materials to be extracted from the environment. Many industries and municipalities are investing in resource recovery initiatives to improve their sustainability and reduce their environmental impact. Research in this area focuses on developing new technologies and strategies to improve the efficiency and effectiveness of resource recovery processes.
