About the book
The disposal and use of sludge is a matter that must be scientifically managed. The sludge produced in municipal wastewater treatment plants is only a few percents of the volume of treated wastewater, but its treatment accounts approximately half of the total operating costs. Therefore, the need to accomplish a sustainable sludge management strategy is becoming increasingly challenging. Because options like an application of sludge to soil for agricultural purposes are gradually restricted and often prohibited by law, innovative systems need to be developed to maximize the recovery of useful materials and/or energy. The aim of this book is to provide integrated approaches, including a change towards more sustainable procedures, assessment of management paths that can maximize the benefits of recycling/recovery, low energy-efficient systems, and development of operational systems tailored to local conditions. “Sustainable Sludge Management Book” will cover topics such as biological conversion of sludge into value-added products such as biological pesticides, biological preservatives, enzymes, bioplastics and biofertilizers/biological fillers; biosolids, as well as conventional sludge processing technologies. It will also discuss ecological and economic balance for sludge management options.
