Research summary

Professor Stegemann is particularly interested in development of sustainable technologies and systems that will enable return of industrial by-products and residual wastes to the resource loop.

Her research with industrial waste concentrates on understanding physical, chemicaland biological processes of accumulation, transformation and release ofcontaminants in industrial by-products and environmental media, in relation towaste prevention, treatment and remediation. She is also interested indevelopment of regulations, policy and other systems that affect thesustainable and resource efficient use of materials resources. Much of her workis in collaboration with industry, and she has experience in laboratorycharacterisation of materials, development of technologies and test methods,preparation of regulatory guidance documents, implementation and evaluation oftechnologies at field scale, and databases and computer modelling.

Please refer to “Research Activities” tab to see a list of specific projects.

Teaching summary

Professor Stegemannwas the first Programme Director of our undergraduate degree inEnvironmental Engineering, and, together with the Civil Engineering ProgrammeDirector and the teaching team, implemented a highly successful new structurebased around eight week-long “Scenarios” for problem-based learning in firstand second year, for which she received a "Provost's TeachingAward".  The Scenarios are models for the "Challenges" thatform part of the new Integrated Engineering degree since 2014.   

Professor Stegemann currentlyteaches an advanced module on“Waste & Resource Efficiency”. She also advises students on their undergraduate, MSc, and MPhil/PhDresearch projects.

For industry, she offers a week-long short course on “Treatment of Industrial Waste byStabilisation/ Solidification”, by special arrangement.

Professor JuliaStegemann has been doing research to support resource efficiency and rationaldecision-making about environmental technologies for more than thirty years. She is a founding Director of CircEL, the UCL Circular Economy Laboratory, a hub for research and education on resource efficiency that spans the breadth and depth of UCL expertise in this area, and PI and Director of the £8M UKRI Interdisciplinary Circular Economy Centre for Mineral-based Construction Materials (https://ce-hub.org/centre-for-mineral-based-construction-materials/).

She is currently closely involved with projects to investigate the geochemical basis of the metabolism of toxic metals in the cement kiln during co-processing wastes,  re-use timber waste, and develop tools to enable use of anthropogenic resources.

Professor Stegemann started her careerdeveloping and validating an evaluation protocol for stabilised/solidifiedproducts for Environment Canada, in collaboration with other Canadianregulators and the US Environmental Protection Agency, as well as 17 industrialcollaborators. This approach to waste characterisation and leaching has gainedinternational recognition, and forms the basis of current standards used inboth North America and Europe, to facilitate more informed waste managementdecisions. She has continued to work in this area in the UK, having led aEuropean project (NNAPICS) to develop a database and neural network models topredict the properties of stabilised/solidified products at Imperial CollegeLondon, as well as a 22-partner project (ProCeSS) under the UK TechnologyStrategy Board Technology Programme to optimise genericstabilisation/solidification processes for increased technology transparencyand support standards for good practice, since coming to UCL.  She hasalso participated widely in other national and international collaborations,e.g., in development of a self-sealing/self-healing mineral-based liner/coverfor landfills and mining waste impoundments with the Netherlands EnergyResearch Foundation (ECN), as a core member of the EPSRC Network for S/STreatment and Remediation (STARNET) and also the Work Package on SedimentQuality and Impact Assessment of Pollutants of the European Sediment ResearchNetwork (SEDNET).   She is a Fellow ofthe Institute of Materials, Minerals & Mining (IoM3), on the board of the International Society for Constructionwith Wastes (ISCOWA), and has been on the scientific committee of 16international conferences.

In addition to research collaborations, she is involved with industry on arange of consultancy activities, including provision of advice, technologydevelopment, testing, auditing, acting as an expert witness, and provision ofstaff training.
