Abstract
Sewage sludge is the residual product from wastewater treatment plants (WWTPs). Due to the rapid increases in the world population and urbanization, increased volumes of sludge from WWTPs have become a global concern. Disposal of sewage sludge is challenging, as it contains organic, heavy metal, and toxic contaminants that pose environmental hazards. However, sewage sludge can also be considered as a source of renewable energy. This chapter discusses various strategies for the disposal of sewage sludge including commercially viable processes and technologies for conversion of sludge to energy, including various recent innovative technologies for the production of clean and sustainable energy from sewage sludge. Moreover, various associated challenges and current efforts to improve operation of these technologies, along with future prospects, are discussed in this chapter.
