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, and achievement of "end-of-waste" status.
Her research with industrial waste concentrates on understanding physical, chemical and biological processes of accumulation, transformation and release of contaminants in industrial by-products and environmental media, in relation to waste prevention, treatment and remediation. She is also interested in development of regulations, policy and other systems that affect the sustainable and resource efficient use of materials resources. Much of her work is in collaboration with industry, and she has experience in laboratory characterisation of materials, development of technologies and test methods, preparation of regulatory guidance documents, implementation and evaluation of technologies at field scale, and databases and computer modelling.

Professor Julia Stegemann has been doing research to support resource efficiency and rational decision-making about environmental technologies for more than twenty-five years.
Currently she is funded by EPSRC and the National Science Foundation of China to work with the China Building Materials Academy and South China University of Science & Technology on investigating the geochemical basis of the metabolism of toxic metals in the cement kiln during co-processing wastes, and is collaborating with colleagues at UCL to form a hub for research on the circular economy, CircEL, in collaboration with the Ellen MacArthur Foundation. Professor Stegemann started her career developing and validating an evaluation protocol for stabilised/solidified products for Environment Canada, in collaboration with other Canadian regulators and the US Environmental Protection Agency, as well as 17 industrial collaborators. This approach to waste characterisation and leaching has gained international recognition, and forms the basis of current standards used in both North America and Europe, to facilitate more informed waste management decisions. She has continued to work in this area in the UK, having led a European project (NNAPICS) to develop a database and neural network models to predict the properties of stabilised/solidified products at Imperial College London, as well as a 22-partner project (ProCeSS) under the UK Technology Strategy Board Technology Programme to optimise generic stabilisation/solidification processes for increased technology transparency and support standards for good practice, since coming to UCL. She has also participated widely in other national and international collaborations, e.g., in development of a self-sealing/self-healing mineral-based liner/cover for landfills and mining waste impoundments with the Netherlands Energy Research Foundation (ECN), as a core member of the EPSRC Network for S/S Treatment and Remediation (STARNET) and also the Work Package on Sediment Quality and Impact Assessment of Pollutants of the European Sediment Research Network (SEDNET). She is a Fellow of the Institute of Materials, Minerals & Mining (IoM3), on the board of the International Society for Construction with Wastes (ISCOWA), and has been on the scientific committee of 15 international conferences.
In addition to research collaborations, she is involved with industry on a range of consultancy activities, including provision of advice, technology development, testing, auditing, acting as an expert witness, and provision of staff training.
