Contact Professor Philip Longhurst
Areas of expertise
Phil has a PhD in Innovation & Technology Assessment, and a degree in Design and Technology and B.Ed. (Hons). On completion of his doctoral studies hedeveloped a programme of research studies assessing the impact of waste management on air quality and neighbouring communities. He adapted measurement and assessment methods from meteorology and agricultural applications to predict the impact of landfill operations on households. Information from these methods were used to inform operators on options for improvement, advise on the potential impacts and opportunities for the control of operations for planning applications, and assess the potential for new methods of operational control and regulation.
Prior to his research career, Phil completed his initial studies at the London College of Furniture and then worked in the furniture industry and associated trades. He trained as a teacher of Design and Technology gaining sponsorship for the development of demonstrator wind tunnels for use in education, then joined Cranfield University to further develop his research and industry interests.
Professor Longhurst holds the Chair of Environment and Energy Technology and is based in the Energy Theme. His research investigates the way that materials can be recovered or diverted from landfill to improve resource use and reduce environmental pollution. His research contributes to the activity in Bioenergy and has a wide portfolio of projects including; creating wealth from recovering trace metals in contaminated land, nutrient recovery from waste, risk assessment for PAS100 compost for use in agriculture, and risk assessment for PAS110 Anaerobic Digestion (AD) residues in agriculture, developing benchmarking methods for better environmental regulation, establishing opportunities for SMEs to develop AD infrastructure capacity, and systems modelling for waste minimisation and policy appraisal.
His published outputs include research into: the mechanical-biological treatment (MBT) of solid waste; the production and quality of solid recovered fuels (SRF); bioaerosol emissions from in-vessel and open-windrow composting; and the risk assessment of wastes, including animal carcasses; and a systems analysis of disease incursion networks.
He has developed short courses including training for improved biowaste regulation, training for odour control and measurement as well as advised site operators on methods to reduce the impact of operations and evaluated levels of compliance with site emission measurements and dispersion modelling methods.
Phil contributed to HM Treasury’s Infrastructure study by the Engineering Interdependencies Expert Group (EIEG), and provides teaching and research supervision to three teaching themes in: Energy; Environment and Agrifood, as well as supervising doctoral researchers.
