The 20th century oversaw a 23-fold increase in accumulated resources extracted, including materials currently locked in buildings and infrastructure (1). This rate of consumption far exceeds the planet’s capacity to regenerate, and has serious implications for global greenhouse gas (GHG) emissions and poses significant challenges to meeting the Sustainable Development Goals in the next decade. Addressing this requires a step change in practice, and implementation of circular economic (CE) reduce-reuse-recycle strategies, where materials are highly valued and remain in use for as long as possible. However, detailed knowledge of material types and quantities that are locked in the building stock is lacking, making any estimate of CE potential unfeasible.
This PhD project will tackle this lack of data by exploring the extent to which satellite and remote sensing data can be utilised to estimate material/component stocks in the built environment, focusing initially on the UK. A wide range of large datasets will be investigated, e.g. nighttime light maps, population density maps, and thermal data maps. There will also be the potential to explore hybrid material flow analysis techniques (2) as part of the project. It is likely that Geographical Information System (GIS) tools will be utilised in order to analyse and visualise data and results.
The successful applicant will join the successful and friendly RISE – Resources, Infrastructure Systems and built Environments group in the Department of Civil and Structural Engineering.
The student undertaking this project will have the opportunity to be a University of Sheffield Grantham scholar and to take advantage of the programme of sustainability training offered. The Grantham Centre for Sustainable Futures focuses on advancing sustainability research and connecting it with the policy debate around how humans can live in a more sustainable way (grantham.sheffield.ac.uk).
Grantham scholars combine outstanding intellect with a strong commitment to public engagement, leadership and action. These ambitious individuals undertake interdisciplinary PhD research projects to help solve the challenges of sustainability. They will be supported by the Centre through a unique training programme, designed to equip them with the skills to become policy advocates and leaders in sustainability matters.
