Scalable Circular Supply Chain For the Built Environment
Lead Research Organisation:
CARDIFF UNIVERSITY
Department Name: Cardiff Business School
Abstract
This project will demonstrate how one of the largest industries in the UK can utilise a digital platform to harness the benefits of a sustainable circular supply chain, so as to reduce waste, increase safety, and promote greater fiscal responsibility. The Architecture, Engineering & Construction (AEC) sector plays a crucial role in the UK economy by employing over 2 million people to deliver civil engineering projects that underpin our economic growth. One of the biggest contributors to GDP, the ACE sector represents commercial activity spanning individual contractors through to multi-national corporations collaborating through complex asset distribution networks that account for over £10 billion of trade.
This network of activity consumes millions of tonnes of materials and produces more waste than all other industries combined, partly due to an inability to maintain an industry wide knowledge of material usage. Reclamation accounts for a fraction of industry activity due to intensive manual costs and is only economically viable for high cost, often historically valuable, materials. A key challenge therefore is a need to not only reclaim, but to track all material/asset usage throughout their lifecycles. Our approach is to build a digital platform and assess the associated business models within which the built environment can provide the tracing of materials without evasive building inspections for recall and resume activity.
The main outcomes of the research will be:
1. A digital (software) platform that harnesses the potential of multi-layered blockchains, to balance local autonomy of transaction recording/management, whilst maintaining a consistent provenance trail of recorded activity within each stage of the AEC lifecycle.
2. The concept and implementation of a 'material & service passport' to show the circularity potential of materials/ components/ assets/ services and enable stakeholders (e.g. designers, main contractors, manufacturers and clients) to assess the likelihood for circularity.
3. A road map based on the co-developed (with industry) digital platform and circular supply chain models, to incentivise collective supply chain behaviours towards circular economy and environmental sustainability.

Achieving net zero neighborhoods: A case study review of circular economy initiatives for South Wales
in Journal of Cleaner Production
| Description | We are developing an information architecture with a blockchain-enabled backbone to capture data about a material throughout its entire lifecycle. This system centers around the concept of digital material passports (DMPs), also known as digital product passports (DPPs). Our blockchain architecture has been successfully tested in a recycled wood use case scenario for construction, demonstrating its effectiveness. We are now developing an online secondary materials marketplace to integrate with the DMP system. Our supply chain and engineering teams are investigating how DMPs can be used as a catalyst for circular practices within the supply chain. We have conducted six case studies of previous DMP initiatives, gaining valuable insights. A business canvas model was developed to illustrate the value proposition for all stakeholders involved. Additionally, we are creating a generic framework outlining the core components for DMP adoption in construction supply chains. |
| Exploitation Route | Expanding the use case scenarios to encompass a wider range of materials could improve the technical architecture's generalizability within the construction sector. Additionally, exploring applications in other industries such as EV batteries, fashion texitle etc. would hold promise too. We delve into DMPs' potential to catalyze circular practices within supply chains through lifecycle assessment. Future investigations could center on how DMPs incentivize such practices, potentially through cost-benefit analyses. The development of a generic framework for DMP adoption in construction offers a valuable foundation. Piloting this framework in real-world projects can refine its effectiveness, while user studies can illuminate stakeholder needs and concerns. This combined knowledge can inform the development of a robust roadmap for DMP's further diffusion in supply chains. Our work attempts to integrate DMP with online marketplace and future work could expand to explore what logistics infrastructures should be established to support the online provisions, e.g. logistics hubs and new intermediaries. |
| Sectors | Construction Digital/Communication/Information Technologies (including Software) |
| Description | Several industry partners, including Waterman, Allies and Morrison, and Maconda Solutions, have expressed interest in collaborating and testing our digital architecture. The findings will inform the UK Green Building Council's (UKGBC) Circular Economy and Net Zero roadmap working group, where the project lead (PI) is a core member. This collaboration could very likely lead to a co-developed policy paper with UKGBC. Additionally, the Foundation for International Blockchain and Real Estate Expertise (FIBREE), a non-profit global organization in the built environment, has comitted to incorporate the findings and disseminate them among its members.Furthermore, our team has been invited to join a consortium of London local councils working to establish an online secondary materials marketplace that integrates DMPs. We believe this collaboration has significant potential to impact industry practices too. |

| Description | New collaboration - EU project (Digital Deconstruction) |
| Organisation | Luxembourg Institute of Science and Technology |
| Country | Luxembourg |
| Sector | Academic/University |
| PI Contribution | Digital Deconstruction (DDC) is an innovated Interreg North West Europe project in which smart services are developed to make circular construction possible and the environment green. The project aims to develop an innovative digital decision support system, integrating various digital tools (3D scanning, Building Information Modelling, a digital materials & buildings database, blockchain technology) that helps to define the most sustainable and economical deconstruction and reuse strategy for building. Therefore it has a lot of synergies with our project. We exchange our insights with our European counter parts, and have presented our findings from a supply chain perspective at one of their workshops in December 2022. |
| Collaborator Contribution | DDC project is much larger in scale and in scope than our project, and started in 2019 and will finish 2023. Therefore some of their research findings already published and provide great insights to us, especially on the blockchain platform they have built and the pilot deconstruction projects. Therefore provides great spring board for us to develop our research further, ensuring our efforts on the right path. |
