Research interests

Current research interests are in the use of biological systems for energy production, biomass production for biorefineries and pollution remediation.

Renewable energy production through anaerobic digestion: Comparative performance of a range of process configurations and operating regimes for biowaste and energy crop substrates, including single and multi-phase operation; high and low solids contents; and mesophilic and thermophilic temperatures. The aim is to identify to optimum systems in terms of specific and volumetric methane yields to support the analysis of overall energy production potential.

Algal systems: This builds on EU-funded work in central Asia on factors affecting the performance of waste stabilisation ponds. The results have led to novel approaches based on designing for seasonal variation and local climate conditions. The research has now developed into the broader theme of non-steady state conditions, with much wider applications:

  • Algal biomass for renewable energy and biorefinery product generation
  • Light penetration in pure and mixed algal cultures
  • Growth of other microbial groups, such as purple non-sulphur bacteria
  • Oxygen productivity as an indicator of the health of algal systems
  • Simple and complex climate-based models for design and performance of algal systems in different regions
  • Integration into water conservation and irrigation schemes

Waste management: Projects include the EPSRC-funded SUE Waste Consortium and the Defra New Technologies programme, looking mainly at quantitative and systems-related aspects (e.g. energy footprinting, waste audit and logistics).

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).    

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).

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

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.

This EPSRC-funded project formed part of the Sustainable Urban Environment (SUE) Waste Consortium (GR/S79626/01).

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

Study of the parameters for optimisation of the design and performance of waste stabilisation ponds in extreme continental climates

Waste stabilisation ponds in continental climates operate in very different modes in different seasons. This research was carried out in conjunction with an EU FP4 project to establish the parameters affecting design and operation.

Study of the equilibrium and kinetics of mercury sorption and desorption by power station fly ash and assessment of the role of ash in limiting the bio-availability of mercury

This project aimed to provide detailed knowledge of the processes by which power station ash acts as a sorbent for mercury, allowing it to be considered as a potential remediation material.

Satellite image processing techniques for effective management of land use and irrigation demand in the Aral basin - INTAS Aral

It is estimated that effective management of irrigated agriculture in the Aral basin could save up to 10% of the region’s water, doubling the flow to the severely degraded lower reaches and contributing significantly to the preservation of the region’s biodiversity and its human and natural ecosystems. This research aimed to provide a scientifically-proven methodology by which agricultural land use can be determined from multi-spectral satellite imagery. The method was then applied, in conjunction with an existing water resource management model for the Syr Darya river, to provide up-to-date information for calculation of crop water demand. The result is a cost-effective system that is capable of identifying the extent and location of wasted irrigation water, and of examining the effects of alternative management options. The overall goal was to provide practical tools that will allow rational planning and utilisation of the Aral basin's land and water resources.

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.

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.
