Upcoming Opportunities for Students
The ICEC-MCM has a large programme for PhD studentships听across different universities听and expect to recruit a cohort听that will commence their doctoral studies in听3Q听2024. The PhD studentships apply to听UK home students听however,听students听not eligible for UK fee status听can apply but will have to arrange funding for the difference between the UK (home) rate and the overseas rate themselves.听If you are interested to take on a new challenge in the area of circular economy and听mineral based听construction materials, please do get in touch.

Background听
Demand for materials and energy are increasing. Decarbonisation ambitions such as the Paris Agreement imply a radical longer-term shift from fossil materials utilisation (e.g.听fuels for energy, feedstock for chemicals) to minerals (e.g. metals for renewable energy technologies) and biomass (e.g. bio-derived chemicals). Shorter-term shifts in resource flows can also have huge socioeconomic implications, such as the UK 鈥榚nergy crisis鈥櫶�(2022). However, the socioeconomic impacts of these issues, which often arise from significant supply-demand mismatches, remain poorly understood. Hence, there is a growing and urgent need to systemically quantify and analyse how resources are used in the economy, to discover sustainable production-usage patterns that avoid supply-demand mismatches in the shorter and longer terms. This information then needs to be disseminated听to policymakers, industry, and the resource community, so the necessary systemic actions can be taken to mitigate undesirable impacts.
Previous听research by Myers and colleagues on this topic, funded by the UKRI Circular Economy Centre in Mineral-Based Construction Materials [1], the Office for National Statistics, and as part of the Imperial-X Resources Observatory (RO) [2], has developed the Bayesian material flow analysis methodology听needed for a quantitative digital twin of the physical economy [3]. This research involves comprehensive mapping of resource stocks and flows from extraction through to end-of-life, and then application of this systemic quantitative evidence to inform policymaking and business strategy.
The vision for its application is to focus on resource emergencies and black swan events (UK energy crisis, semiconductor chip shortage, trade partner import/export bans such as the Rare Earth Crisis [4], etc.), to better understand these and to both propose mitigating policies and understand their efficacy 鈥� much like COVID-19 epidemiological modelling in SAGES [5], which showed effects of individual measures like social distancing on COVID-19 infections/mortality and demand for health services [6]. This approach was initially demonstrated听by its application to understand the supply/demand balance of construction aggregates in England until 2030. We are now seeking听to enhance its capability by applying it to other material systems and important current resource issues.听
This PhD project will focus on improving the capability of Bayesian material flow analysis methodology听to include multi-regional systems and energy stocks and flows (by incorporating energy balances). This will include application of statistics and scientific programming in our existing Python code. The improved methodology听and code will be applied to analyse the supply/demand balance of energy materials in UK and its major trading partners. We plan to focus on the current 鈥榚nergy crisis鈥櫶齛nd understand the landscape of energy material supply scenarios available to the UK and how these marry up to its demand. This will include the major energy production sites (and their processing steps) that supply (refined) energy materials to the UK.听
Aims & Objectives 听
- Development of datasets describing the material and energy compositions of products and production/waste treatment/recycling process inputs and outputs 听
- Improvement of our Python code (on our Imperial-hosted github听repository) so it can ingest both material and energy data, and听splice its outputs by region (e.g.听UK), material or energy cycle, and product (or product category, e.g. electricity generation). 听
- We expect that these advancements will be demonstrated听by modelling different competing technology options within the same product category, e.g.听different energy sources for electricity generation, to understand their resource implications. Dissemination of these research outcomes to key stakeholders such as policymakers will also be key.听

Background
Construction and demolition waste (CDW) is the largest fraction of all waste generated in the UK and one of the most resource intense sectors in the economy. In 2020, CDW accounted for around 59 million tonnes. C&D waste contains an array of different materials including metals, concrete, bricks, glass, wood, plaster board, plastics and other fractions. Construction material manufacturing is also an energy and resource intense sector. While the recovery rates of CDW in the UK are very high, with 92.6% reported in 2020, and the value of some of these resources is potentially high, current models and practices in the sector mean that most of these materials are not recovered back for the primary use and that their value is marginal, creating little incentives for a better alignment with CE principle of keeping material at their highest value.
The current waste regulation specifies the preparing for re-use, recycling and other material recovery of non-hazardous construction and demolition shall be increased to a minimum of 70 % by weight, which is already widely achieved in construction and demolition projects, but the next step is to move towards achieving reuse of material components and systems, and, where that is not possible, ensuring high quality recycling, so that they can substitute primary materials and help construction material organisations achieve higher fractions of recycled content, which is increasingly being specified by clients.
Buildings and infrastructures can be built as material banks by incorporating easy to dissemble and reuse building systems. This requires changes along the design phase, construction/ installation and full traceability of the performance of the systems over time and changes in the industry practice in terms of maintenance, recovering, reconditioning and remanufacturing. The project will focus on exploring business models and industry practice around the introduction of reusable building systems and closed loop recovery of materials.
Aims & Objectives
The specific scope of the PhD project will be defined in collaboration with the industrial sponsor to ensure that the project is relevant and aligns with the organisation鈥檚 main priority areas:
- Define procedures for designing, installing and maintaining reusable building systems and components
- Identify business models and modes of operation for the shift towards reusable building components
- Explore routes for re-conditioning and remanufacturing reusable building components in a closed-loop system
- 听Identify design and installation procedures and contractual procedures that enable recovery of reusable systems
- Explore the role of material passports to enhance traceability of materials in buildings and help to assess recovery potential
