The composition of sewage sludge makes it a potential source for the recovery or production of value-added products. This chapter explains recent advances in the use of activated sludge for polyhydroxyalkanoates (PHA) production, Bacillus thuringiensis (Bt) based biopesticides production/formulations, vermicomposting biotechnology, and production of different enzymes. PHAs are one of the relatively newer families of biodegradable polymers that have great potential in the future due to their properties. The key success of biopesticides lies in their impact on the target pest, market size, and variability of field performance, cost effectiveness, and end-user feedback. Bt is commercially used to control forests and agriculture insects. Wastewater sludge could be used as a potential source for isolation of microorganisms and can be a very good carbon source of many microbial possesses that could add value to sludge by producing valuable metabolic products.
