Prof. Charles Banks is an Emeritus Professor within Engineering and Physical Sciences at the University of Southampton.

Research interests are in the area of innovative technology for environmental protection, including:

Current research projects reflect these interests and have led to the design of novel reactor systems and operating protocols to meet the challenges of new and adapted technologies for environmental protection, renewable energy production and sustainable nutrient management systems. Of special interest is the development of operating protocols for anaerobic digestion, to maximise rates of substrate conversion and biogas yield. As part of this, current research is promoting the use of mass and energy balances as a means of quantifying process performance and developing new analytical tools to broaden our understanding of the process, its kinetics and limitations. Earlier research on wastewater treatment systems based on algal photosynthesis is now linking together with some existing themes including growth of algal biomass for energy production and product generation in biorefineries: this encompasses work on reactor design and biochemical pathways.

Research project(s)

Biomethanisation of CO2 in Anaerobic Digestion Plants

This project is part of the IB Catalyst programme jointly funded by Innovate UK, the Engineering and Physical Sciences Research Council (EPSRC) and the Biotechnology and Biological Sciences Research Council (BBSRC).

Effective mass transfer of hydrogen into digester mixed liquor for biomethanisation of biogas CO2

A current challenge with intermittent generation of renewable energy is finding an energy storage solution to provide energy at a time to meet consumer demand. Electrolytic production of H2 has been proposed, however this is currently limited by a lack of H2 infrastructure for storage and usage. H2 can be combined biochemically, however, with CO2 to form CH4 in an anaerobic reactor. This process increases the carbon utilisation of waste biomass in anaerobic digestion, producing biomethane which can act as a substitute to natural gas in our current gas infrastructure. This project investigates the mass transfer of H2 into an anaerobic reactor and the performance of the digester considering the effect on pH from a reduced concentration of bicarbonate in the digester liquor.

SUPERGEN

This collaborative project is aimed at developing a beneficial synergy between anaerobic digestion (AD) and pyrolysis for the processing of non-source segregated organic fraction of municipal solid waste (MSW).

Spring ponds - algal biomass systems

The research considers a range of factors affecting algal revival and growth, focusing particularly on phenomena in the unsteady state period occurring between the end of winter and the onset of summer conditions.

VALORGAS - Valorisation of food waste to biogas

AD is not a new technology, but its application for energy recovery in the field of municipal waste treatment is only just becoming established in Europe, and only for mixed wastes. The use of source segregated food wastes as substrate is not yet widespread, possibly because of technical challenges linked with collection, handling, pre-treatment and digestion of this material. The research includes a number of closely related components with a common underlying goal: to evaluate and where possible improve the energy production process from the perspective of the overall net energy gain achieved within defined system boundaries that include collection, sorting, processing, and beneficial use of recovered material

Industrial Collaboration for Promoting Sustainability

This Knowledge Transfer (KT) project focused on the following key areas: Bioenergy (especially methane production through anaerobic digestion, but also with potential for involvement in other areas e.g. other biofuels, production of pellets for local heat and co-firing in power stations, and pyrolysis of residual municipal wastes for syngas production) Energy footprinting for process optimisation, both in industry and in the waste management sector Energy efficiency studies within companies Urban Sustainability studies (including participation in the Thameside Gateway Institute for Sustainability)

Optimising Inputs and Outputs from Anaerobic Digestion Processes

The aim of the work was to better understand the factors influencing the stabilisation of the organic fraction of municipal solid waste (MSW) in the anaerobic digestion process. In particular the research addressed whether stabilisation, as judged by volumetric gas production, solids destruction and bio-stability of the residues, could be improved by co-digestion with other organic wastes from industry, commerce and agriculture.

EU - China Cooperation for Liquid Fuels

ECOFUEL is building an international partnership for new second generation biofuel processes: the research will set the foundation stones for the technologies being developed, and make further contributions to overcoming barriers to commercialisation.

Development of low-cost methods for treatment and reuse of drainage and urban wastewater by adaptation of waste stabilisation ponds for extreme continental climates

If properly operated, cold climate waste stabilisation ponds (WSP) offer an extremely efficient means of treating raw sewage to provide a high-quality effluent at low cost, which can be used for irrigation purposes or returned to the rivers. Because of the desperate shortage of water resources in many regions, the country's vast land area and difficulties with the provision of effective conventional wastewater treatment in many cities, waste stabilisation ponds are of particular relevance to Kazakhstan and Central Asia. This EU-funded project aimed at improving our knowledge of such systems in order to optimise their design and performance
