Areas of Expertise / Modules taught

Professor Richard Dinsdale, is chair of Sustainable Environmental Systems in the Sustainable Environment Research Centre at the University of South Wales. I am a biologist by training and conduct research into integrating biological and physic-chemical processes to develop holistic solutions to reduce the impacts of human activities on the natural environment. My particular interest is in the production of energy products such as hydrogen, methane or electricity or materials such as volatile fatty acids and bioplastics using micro-organisms from wastes or low grade biomass. My other interests include environmental analysis, process monitoring and control, development and life cycle analysis of anaerobic digestion and wastewater treatment.

I teach the following modules: PH4S05: Water and Wastewater Treatment Processes.


After working as a microbiologist in a pharmaceutical company and completing my first degree I started my academic career in the area of environmental biotechnology in 1991. My first degree was in Applied Biology (Biotechnology) with my second degree (PhD) in the field of anaerobic digestion from the Dept. of Production and Manufacturing Engineering, University of Glamorgan. My research activities are directed at optimizing microbial cultures for the production of energy either in the form of methane, hydrogen or as electricity directly from bioelectrochemical systems as well as other chemical products such as bioplastics, single cell protein and lipids from low grade biomass resources. This includes either liquid or solids wastes as well as from CO2, H2 and CO gases. I am also interested in the development of novel instrumentation and its implementation in control systems for bioprocess optimization. In recent years I have been concentrating on the development of biolectrochemical systems (BES). I have received funding either as principal investigator or co-investigator of over £6 million from the EPSRC, BBSRC, NERC, the European Framework research programs, European regional development funding or industry. I have been funded in 5 EPSRC SUPERGEN projects and was the scientist in charge of a FP6 Marie Curie TOK project. I have had two recent BBSRC POC concept projects from the Anaerobic Digestion and C1 NIBBS. My current funding also includes 5 TATA Steel and 3 Welsh Water supported studentships. I am also a co-investigator on a project investigating the use of an oscillatory baffled reactor for enhanced 1C gas bioconversion for energy production and storage funded by BBSRC/INOVATE UK, from the EPSRC: “Liquid Fuel and bioEnergy Supply from CO2 Reduction” (LifesCO2R) (EP/N009746/1), NERC: “Resource Recovery from Wastewater with Bioelectrochemical Systems” (METEORR) (NE/L014246/1) and BBSRC: ToOLTuBES: Toxicity & Organic Load Tracking using BioElectrochemical Systems (BBSRC/ BB/R005613/1). I have supervised over 15 PhD students to completion. I have acted as an external examiner for the award of PhD seven times, internally 5 times and acted an internal viva chair 5 times. On the Scopus database, I have over 80 published international journal papers and an H Index of 36.
