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 depend on subsidies and hardly survive their pilot phase, hopeful signs of...

Bodily waste is common to all and as natural as breathing. We prefer not to talk about it, but we should even those of us who take care of our business in pristine, sanitary conditions. Disease spread by bodily waste kills more people worldwide every year than any other single cause of death. Even in the United States, nearly two million people have no access to an indoor toilet, while the sewers of major cities worldwide are an infrastructure disaster waiting...

Environmental pollutants have become a major global concern. The modern growth of industrialization, urbanization, modern agricultural development and energy generation have resulted in indiscriminate exploitation of natural resources for fulfilling the human desires and needs, which have contributed in disturbing the ecological balance on which the quality of environment depends. The modern technological advancements in chemical processes/operations have been raised to new products and also new pollutants in abundant level which are above the self cleaning capacity of the environment. One...

Among the goals of environmentally sound waste treatment is the recycling of organic wastes. The most practiced options are composting and anaerobic digestion, both processes being carried out by microorganisms. This book provides an overview of the various ways microbes are doing their job and gives the reader an impression of their potential.

The sixteen chapters of this book summarize the advantages and disadvantages of treatment processes, whether they are aerobic like composting or work without oxygen like anaerobic digestion for biogas (methane) production. These chapters show...
