Plant microbial fuel cell based green power generation along with soil and wastewater treatment: A mini review

Abstract

Wetlands along with plant microbial fuel cell (PMFC) can be utilized for large power generation. Emission of greenhouse gases is lesser relative to conventional MFC technique and direct chemical to electrical conversion ensure high efficiency with treatment of polluted soil. If soil polluted with metal is filled with soil and plantation in cathode chamber of PMFCs then root zone oxygen leakage could be used for aeration requirement. Hence a parallel solution towards electricity generation, wastewater and soil matrix decontamination is obtained. This paper gives theoretical brief possibility of PMFCs effectiveness for electricity generation and soil treatments.
