12 - Bio-electrochemical systems for sustainable energy production and environmental prospects

Abstract

The growing recognition of the energy-atmosphere relationship is enforcing the advancement of environmental remediation machinery for eco-friendly power generation and energy dissipation. Bio-electrochemical systems (BESs) are new methods for changing chemical energy to electrical energy (and vice versa) that integrate microorganisms as catalysts. This chapter gives a broad survey of the mechanisms of different types of BES technology for productive and sustainable ecological remediation plus energy production, including azo colorants and metals. Moreover, it addresses the possible innovative applications of BES methods for removing pollutants. The novel point of BES for environmental remediation is the application of probes as non-inadequate electron gainers, or indeed contributors, toward impurity squalor. BESs require small amounts of power or substances, but they generate sustainable potential to nurture and additional deskside usages as an alternative. BESs deliver mutual redox reactions that participate in microbial electrochemical subtraction tools, so mixed pollutants may be detached. This chapter also critiques the scope of electrochemical CO2 reduction and urea oxidation reaction toward value-added products. The chapter ends with conclusions and future perspectives.
