Dr Colin Hills is a University Reader and Director of the Centre for Contaminated Land Remediation at the University of Greenwich. He has been actively involved in stabilisation/solidification (s/s) Research and development for more than 25 years. His work includes national guidance on s/s of contaminated soil for the Environment Agency (England and Wales), and the development of novel s/s systems. He has received a number of national prizes, including the 2006 IChemE Green Chemical Technology Award and the 2008 Times HE Award for his outstanding contribution to Innovation and Technology, through his work on using CO2 gas to treat contaminated soil and waste.
Dr Hills studied Geology (BSc) and Industrial Petrology (MSc) at Queen Mary College, London. His PhD (Imperial College) in environmental engineering followed a period working as a field geologist in the Middle East and West Africa (Stanger, Intersite, Nigeria Dredging and Marine), and in process technology and engineering for Redland (now Lafarge). Dr Hills joined the University of Greenwich as a Senior Research Fellow in 1998, and was appointed Reader in 2002.
Dr Hills is Programme Leader for Master's by Research (Science) and Course co-ordinator for Practical Science Skills for Environmental Scientists and Geographers and (L1) and Environmental Management (L2). Both courses are designed to teach fundamental field and laboratory skills and provide an awareness of the importance and impact of environmental science on our lives and wellbeing.
Dr Hills is Postgraduate Tutor for the School of Science and has recently been appointed as the Schools Overseas Liaison Officer.

Dr Colin Hills' current research interests include the use of carbon dioxide gas to treat soil and waste through accelerated carbonation, the production of construction materials from waste, formulation of novel cement systems and the diversion of waste from landfill.
The valorisation of waste streams and their beneficial re-use is an important area of his research and he is currently working with BP and other companies in this respect.
Dr Hills is a member of the School of Science Environment and Sustainability Research Cluster.
The Passify project (Performance Assessment of Stabilised/Solidified Waste Forms) investigated the long-term effectiveness of stabilisation/solidification (s/s) of contaminated soil based on:
The core partners were the University of Greenwich, University of New Hampshire and INERTEC. CLA:IRE, The Welsh Assembly, the PCA, SITA Environmental Trust and Environmental Geotechnics Ltd. were key funding agencies supporting the investigation.
The US Environmental Protection Agency, The Environment Agency and ADEME were key partners in allowing remediated contaminated sites to be invasively investigated. The University of Birmingham, University of Cranfield, The Royal Engineers.
Passify was awarded Eureka Status (S!3308), by the European Union.
The following main tasks were carried out including on samples taken from Superfund sites in the USA:
Dr Hills is a member of the EPSRC Peer review panel (2000-present) and the European Science Foundation Review Panel (2006-present). He is a past Chairman of the Cement and Concrete Group of the Institute of Materials, and a long-standing member of ISCOWA and the Society of Chemical Industries.
Recently, Dr Hills has served as a member of the scientific committee on a number of international conferences, including ACEME 2006-2010, WASCON and was Co-Chair of the International Stabilisation/Solidification Technology Forum held in Canada in June 2010.
As well as serving as a member of the editorial staff of Communications in Waste Management Dr Hills has been a Guest Editor for the International Journal of Environmental Technology and Management. He is a regular reviewer for a number of International Journals including: Environmental Science and Technology, Waste Management, Journal of Hazardous Materials and Waste and Resource Management
In September 2006, Dr Hills was awarded the 2006 Green Chemistry Prize (IChemE/Chemistry Innovation KTN) in his role as one of the Founder Directors of Carbon8 Systems Ltd., the University of Greenwich spinout company. Carbon8 Systems won both the Kent Innovation Challenge and the Kent Environment Awards in 2007.
In 2008, Carbon8 Systems was the National Winner of the Shell Springboard Challenge (2008) with a prize of £40k. Later this year Dr Hills received the Times Higher Award for his Outstanding Contribution to Innovation and Technology.
