Title of Talk: Resource recovery from wastewater using microbial electrochemical technologies and wastewater treatment

Advancement in microbial electrochemical technologies (METs) or bioelectrochemical system (BES) research offers new perspectives in the direction of energy / resource recovery (electricity, hydrogen, valuable byproducts) and wastewater treatment through electrochemical routes. Such development in BES provides a flexible platform for various electrochemical reactions and hence provides new dimensions for valuable resource recovery including acids, alcohol, biopolymer, and industrial chemicals. Being an interdisciplinary system, scaling-up of BES is facing microbial, electrochemical, engineering design, and techno-economical challenges which need to be addressed before moving this technology from reality to practical field applications. The gap between practicability and reality of BES technology transformation lies in scalability either by enlarging the size or by stacking arrangements and are subjected to certain design and operational limitations. Several successful pilot scale trials of microbial fuel/electrolysis cells are the key successive indicators for the practical applicability of BES towards technology transfer. This proposal aims to research on advancements in the bioelectrochemical system for resource recovery and scaling-up issues while moving from reality to practicability. Additionally, such METs offer energy recovery, valuable industrial chemical recovery, biohydrogen and electricity recovery, carbon capture-utilization along with simultaneous contaminant removal from wastewater. Such efforts will be useful for improving the rural sanitation practices for effective wastewater treatment and energy recovery.

The major focus of the work will be:

·       Development of microbial fuel cells for electricity generation and wastewater treatment for onsite rural sanitation

·       Biohydrogen production and energy recovery from agricultural biomass feedstock using microbial electrolysis cells

·       Carbon capture and valuable chemicals and resource recovery from carbon dioxide utilization in microbial electrosynthesis system

·       Waste-to-resource recovery options during wastewater treatment using microbial electrochemical technologies with the help of environmental electrochemistry approach

·       Scaling-up of microbial electrochemical technologies and techno-economic feasibility 

Teaching:  Bioenergy generation from biomass conversion

Over the last century, there has been increasing debate concerning the use of biomass for different purposes such as foods, feeds, energy fuels, heating, cooling and most importantly biorefinery feedstock. The biorefinery products were aimed to replace fossil fuels and chemicals as they are renewable form of energy. Biomass accumulates chemical energy in form of carbohydrates through combination of solar power and carbon dioxide during the process of photosynthesis. Bioenergy from biomass refers to the process of converting organic matter, such as plants, agricultural residues, and wood, into usable energy forms. The biomass conversion technologies gained momentum recently due the fact that it is clean, sustainable and renewable source of energy. There are several ways to harness bioenergy from biomass: combustion, pyrolysis, biochemical conversion and bioelectrochemical routes. Selection of biomass conversion technology depends on factors such as the type and availability of biomass feedstock, the desired energy output (heat, electricity, or biofuels), and economic considerations.

 Anaerobic digestion involves the decomposition of organic matter by microorganisms in the absence of oxygen. Fermentation is a biochemical process that converts biomass, primarily sugars and starches, into biofuels such as ethanol. Recent upcoming bioelectrochemical system (BES) also improved the valuable resource recovery (i.e. electricity, biohydrogen, industrial chemicals, nutrients) and energy generation from organic matter during wastewater treatment. Various factors including biomass characteristics, inoculum properties, reactor design, operating conditions affect the performance of biochemical conversion of biomass. Waste utilization is supposedly to be the most economical process for renewable energy production, coupled with its complementary benefit that is to clean the environment. Currently, waste-to-bioenergy production is still not as cost-competitive as fossil-based fuels, based on the current technologies developed. Also, proper waste classification is equally important to ensure higher energy recovery efficiency in power generation and minimize environmental impacts. Techno-economic feasibility of biomass conversion processes are dependent on the price of the initial feedstock used and downstream processing cost.

efficiency, cost-effectiveness, and environmental sustainability of biomass conversion processes.
