Assessment of sewage sludge potential from municipal wastewater treatment plants for sustainable biogas and hydrogen productions in Turkey

Being utilized to produce biogas in anaerobic sludge digestion reactors in wastewater treatment facilities, sludge can also be defined as a carbon neutral biomass and is an effective resource that can be used in preventing global warming. On the other hand, hydrogen production from sludge is a highly noteworthy topic due to hydrogen’s quality of being the clean energy carrier of tomorrow and its production can be achieved through the fermentation of sludge. In this chapter, biogas and hydrogen production potentials of the municipal wastewater treatment facilities in Turkey are evaluated on the basis of sludge generation, and the impact of the developed hydrogen production models on global warming is set forth.
