Leeds has a long-standing legacy in construction innovation, with Portland cement first patented in the city. Today, the School is home to the Neville Centre of Excellence in Cement and Concrete Engineering, a leading hub for low-carbon materials and circular construction. Through interdisciplinary research and strong industry engagement, Leeds contributes to the development of resilient, sustainable infrastructure with global impact. 

Within the consortium, the University of Leeds is the project technology lead and the work package leader on cement and energy (WP4) and life cycle and techno-economic assessment (WP5). Leeds also contributes to concrete characterisation (WP3), and is an active collaborator in dissemination activities for the project (WP6).

Within WP3, we have been involved in developing a database to relate recycled aggregate properties and subsequent concrete performance. 

WP4 has progressed the development of low-carbon cement from recycled concrete paste (RCP), including experimental trials using both conventional and microwave-assisted heating. Alongside experimental work, modelling and thermodynamic analysis are being developed to evaluate energy requirements for clinker production using recycled materials compared to traditional raw inputs. 

Using the database from WP3, we have been able to feed into LCA data to understand the interplay between the emissions associated with the processing of recycled concrete aggregate and the subsequent carbon footprint of recycled aggregate concrete.

‍

NUWEE conducts applied research focused on the valorization of concrete debris as a secondary raw material for modern construction.

A key research focus is the investigation of recycled concrete fines (RCF), including industrially produced HAS Ultrafines. These materials are obtained from industrial partners using everox technology and Eco+Logic facilities, as well as through laboratory-scale crushing and classification of concrete waste.

Within the S3 project, NUWEE has demonstrated the effective use of recycled concrete fine fractions as supplementary cementitious materials, achieving up to 10–15% cement replacement without significant loss of mechanical performance and supporting reduced clinker use and CO₂ emissions. NUWEE’s work includes the development of low‑cement and low‑clinker concrete, mortar, and pressed building materials, supported by activation and processing strategies for recycled materials, including HAS Ultrafines. These achievements contribute to scalable, science‑based solutions for Ukraine’s reconstruction, aligned with circular economy and resource‑efficiency principles.

C2CA / everox Technologies is pioneering the low-energy upcycling of waste concrete into a high-value cement substitute for the construction industry. By substituting cement, everox targets a global CO2 reduction of 2% through its unique technology, while providing secure, local supply and circular value chains.

‍

everox is the primary technology provider to the project and has provided its core equipment of the “ballistic separator (BS)” and “thermo-mechanical separator (TMS)” for operation by the consortium partners in the Ukraine. With this equipment, the consortium was able to upcycle over 6,000 tons of waste concrete and produce recycled materials that have been used in concrete applications.

• Delivered, installed and commissioned key concrete recycling equipment together with consortium partners in Ukraine
• Developed and delivered sensor solution for live quality control and performance data gathering
• Will be re-erecting the full setup in Netherlands to provide continued access to the consortium as well as any resulting business development activities
