Doug Stewart is an engineer whose research focuses on sustainable solutions to geoenvironmental problems. Prior to his PhD, he supervised the construction of fly-ash disposal lagoons and has since provided expert consultancy services during the redevelopment of fly-ash lagoons at a former coal-fired power station in Yorkshire. His research focuses on the environmental impacts of alkaline industrial residue disposal. Particular interests are the impact of high pH on contaminant metal leaching, the interaction of contaminant metals with soil minerals and soil organic matter, and the impact of microorganisms on contaminant mobility. To support his research, he has embedded DNA-based techniques for identifying soil microorganisms and characterising microbial populations into an engineering research group. Lately his focus has been the use of high organic matter secondary materials (e.g. sewage sludge, digestate, compost, etc.) to improve soil function and he has a project on the biochemical-physical-biological function of sludge in agricultural soils (White Rose Studentship Network). Current research projects investigate the growth of a biomass crop on metal contaminated soil, and beneficial reuse of incinerator ashes.
