Resource Recovery and Reuse (RRR) is a subprogram of the CGIAR Research Program on Water, Land and Ecosystems (WLE) dedicated to applied research on the safe recovery of water, nutrients and energy from domestic and agro-industrial waste streams. This subprogram aims to create impact through different lines of action research, including (i) developing and testing scalable RRR business models, (ii) assessing and mitigating risks from RRR for public health and the environment, (iii) supporting public and private entities with innovative approaches for the safe reuse of wastewater and organic waste, and (iv) improving rural-urban linkages and resource allocations while minimizing the negative urban footprint on the peri-urban environment. This subprogram works closely with the World Health Organization (WHO), Food and Agriculture Organization of the United Nations (FAO), United Nations Environment Programme (UNEP), United Nations University (UNU) and many national and international partners across the globe. The RRR series of documents presents summaries and reviews of the subprogram’s research and resulting application guidelines, targeting development experts and others in the research for development continuum.

Bio Refinery of Wastewater Treatment: Way to Generate Waste to Value focuses on the exploitation of various wastewater treatment technologies and microbial, chemical, and physical processes as tools for simultaneous value generation during treatment, degradation, detoxification, and stabilization of toxic and hazardous contaminants and restoring contaminated sites. The book provides recents advancements in integrative and cost-effective wastewater treatment strategies and stipulates all pros and cons of each strategy. Bio Refinery of Wastewater Treatment: Way to Generate Waste to Value is valuable to researchers and scientists, who are working in the field of effluent treatment plants/biodegradation of environmental contaminants for environmental protection and sustainable development. - Provides natural and eco-friendly solutions to deal with the problem of pollution aiming value generation - Details underlying mechanisms of biorefinery approach associated microbes for simultaneous value generation and removal of emerging contaminants - Illustrates numerous successful field studies on the application of bio-refinery approach for eco-restoration of contaminated sites - Presents recent advances and challenges in biorefinery research and applications for sustainable development

Humans generate millions of tons of waste every day. This waste is rich in water, nutrients, energy and organic compounds. Yet waste is not being managed in a way that permits us to derive value from its reuse, whilst millions of farmers struggle with depleted soils and lack of water. This book shows how Resource Recovery and Reuse (RRR) could create livelihoods, enhance food security, support green economies, reduce waste and contribute to cost recovery in the sanitation chain. While many RRR projects fully depend on subsidies and hardly survive their pilot phase, hopeful signs of viable approaches to RRR are emerging around the globe including low- and middle-income countries. These enterprises or projects are tapping into entrepreneurial initiatives and public ̶ private partnerships, leveraging private capital to help realize commercial or social value, shifting the focus from treatment for waste disposal to treatment of waste as a valuable resource for safe reuse. The book provides a compendium of business options for energy, nutrients and water recovery via 24 innovative business models based on an in-depth analysis of over 60 empirical cases, of which 47 from around the world are described and evaluated in a systematic way. The focus is on organic municipal, agro-industrial and food waste, including fecal sludge, supporting a diverse range of business models with potential for large-scale out-and up-scaling.
