Introduction of polyhydroxyalkanoates (PHA) in water treatment systems enables widening of its application in denitrification processes. Emphasising the importance of denitrification in water treatment helps to prevent the surge of nitrate concentrations, thereby hindering eutrophication and maintaining the balance of aquatic ecosystems. Therefore, there is an increasing urgency for the development of sustainable and efficient denitrification techniques to address contemporary challenges in water quality management. PHAs are produced by a variety of microorganisms under limited nutritional conditions and present themselves as promising candidate for denitrification due to their favourable characteristics which include biocompatibility, biodegradability and ability to store carbon and energy. The current chapter delves with the mechanisms governing denitrification employing PHA along with the intricate biochemical pathways and metabolic processes involved. PHA serves a dual role as both a carbon source and an electron donor in denitrifying bacteria, aiding in the conversion of nitrate to nitrogen gas in anaerobic environments. The chapter furthermore addresses various factors such as substrate availability, microbial community composition, and environmental parameters which are affecting the efficiency of PHA-mediated denitrification. Despite the potential advantages, challenges impede the widespread adoption of PHA in denitrification processes. Technical constraints such as substrate availability, yield of PHA and reactor design, coupled with economic factors such as production costs, present significant barriers. Future research endeavours should prioritise optimising processes, surmounting technical and economic hurdles, and comprehending the ecological ramifications for water and wastewater treatment systems using PHA.
