    Industrial wastewater treatment using bioelectrochemical systems and the potential for energy recovery
    (Elsevier, 2022) Kumar, M.; Sinharoy, A.; Uddandarao, U.; Singh, K.S.
    Energy crises and environmental pollution are predicted to be among the major global problems in the 21st century. Over past centuries, massive increase in human population and industrial development has resulted in energy crises, global climate change, environmental degradation, and associated health problems. Therefore, the greatest challenge for researchers is to find alternative sources of energy and means to prevent and reduce environmental degradation, due to which, biotechnological products and processes using renewable resources have gained attention during recent times. In this context, bioelectrochemical systems (BESs) have the potential to provide solutions for simultaneous wastewater treatment and resource recovery in the form of bioenergy and other value added products. Both types of BES, viz., microbial fuel cell and microbial electrolysis cell, are capable of treating wastewater generated from a variety of industrial sources and producing energy (electricity, hydrogen, methane) as well as recovering other resources such as biomass, heavy metals, nutrients (nitrogen, phosphate), and minerals. This chapter is focused on providing a detailed overview of different BESs, more particularly, MFCs used for treatment of industrial wastewater, and the potential for bioenergy production. © 2023 Elsevier Inc.

    Microalgae-based wastewater treatment and resource recovery in the form of bioenergy and other bioproducts
    (wiley, 2022) Sinharoy, A.; Singh, K.S.
    Treatment of industrial wastewater is one of the major challenges in the modern world. This is necessary for protecting our environment, and not taking proactive steps towards this can cause further environmental degradation. Biological treatment technologies received much interest in the past few decades due to their inexpensive character, and this method is considered sustainable and more environmentally friendly. Moreover, public acceptance of biological treatment technologies is higher than other conventional treatment technologies. In the past few decades, increased stress has been given to treating wastewater and recovering valuable resources, further incentivizing the industry to actively develop such waste mitigation processes. Such systems can improve the economics of wastewater treatment. Microalgae-based treatment systems can achieve such targets as microalgae can utilize a wide range of such wastewaters for their growth. The recovered algal biomass can be further processed to produce bioenergy and other valuable products. This chapter intends to discuss the feasibility of algal wastewater treatment from different industrial sources. © 2023 Scrivener Publishing LLC. All rights reserved.
