Tracimat: A C&DW management organisation in Europe (1 November 2023)

Tracimat, a non-profit organisation recognized by the Flemish Ministry of Environment, became operational in 2018. Join the webinar and learn how this organisation contributes to the realization of the circular construction economy, enhances recycling of building materials and gets inspired by this initiative.

Our guest speaker Liesbet, is an MSc Bio-engineer in land and forest management from the University of Ghent (Belgium). She gained experience in the USA and Europe as a consultant in soil and groundwater remediation and environmental due diligence for mergers and acquisitions. Since 2005 she’s been an advisor for the Flemish Construction Confederation on technical environmental issues. Until April 2020 she was responsible for quality management at Grondbank, an excavated soil management organization on which the traceability system Tracimat is based. She was the operational director of Immoterae, an organisation that was founded to valorise the know-how of Grondbank, assessing environmental risks and costs for construction projects. She has been working at Tracimat, a demolition waste management organization, since its startup in April 2014, providing more than 15 years of experience in construction and demolition waste and project management. As director of Tracimat, she’s also overseeing the development of the company.

A practical overview of macroeconomic approaches to circular economy using IO and CGE analysis (4 July 2023)

By Dr. Matthew Winning from UCL

In this webinar, Matt tells us why analysing circular interventions and policies is important to establish potential future outcomes. The linkage between physical and monetary flows and the implementation of policies are often attempted to be captured using top-down economic modelling tools such as Input-Output (IO) and Computable General Equilibrium (CGE) modelling approaches. These can be extended to capture a better representation of circular options. Matthew will provide an introduction to these approaches and present some analysis undertaken at UCL on the steel industry.

CE standards (16 May 2023)

By Gilli Hobbs from Reusefully

Gilli's presentation focuses on the development of standards that support the transition from a linear to a circular economy in the construction sector. Many of the current standards are tethered to a single asset life cycle which can be counter to resource optimisation over multiple product, building and/or infrastructure use cycles. There are also many other priorities for standardisation in this field which are beginning to be addressed through the European and International standards committees relating to ‘Circular Economy in Construction’ and ‘Circular Economy’ respectively.

Transformation of London clay into construction resources (11 Oct 2022)

By Athina Papakosta from HS2 London Tunnels and Fragkoulis Kanavaris from Arup

This brief lunchtime seminar, hosted by ICEC-MCM (Interdisciplinary Circular Economy Centre for Mineral-based Construction Minerals), focused on the Repurposed Excavated Arising Loop (REAL) project . This feasibility study examines whether London Clay can be processed into construction materials, particularly focusing on calcined clay to act as cement replacement in concrete. The session ran through the resource efficiency, waste management, decarbonisation & overall sustainability challenge in the construction industry, the REAL project is seeking to address. Results of the testing of the London Clay raw material for its suitability to produce supplementary cementitious material (SCM) & Light Weight Aggregates (LWA) therefrom, as well as progress on concrete mix designs containing the calcined London Clay cement replacement were presented and discussed.

Introduction of reused materials into the Entopia Building (20 September 2022)

By Peter Kelly from ISG

This brief lunchtime seminar, hosted by ICEC-MCM (Interdisciplinary Circular Economy Centre for Mineral-based Construction Minerals), will focus on The Entopia Building, which is the new headquarters of the Cambridge Institute of Sustainability Leadership. Refurbished from an existing office space, challenging targets were set around sustainability and the adoption of circular principles was a key goal of the project. ISG therefore introduced the first known instance of LED lighting taken from one building and reused at another, secondary steel used for the PV canopy and a beautiful reception desk salvaged from a refurbishment in central London. In this presentation, Peter outlines the challenges of getting these materials reused, installed, share success stories and lessons learned.

How to measure Biodiversity Net Gain in the Built Environment (14 June 2022)

By Julia Baker from Wood Environmental

This brief lunchtime seminar, hosted by ICEC-MCM (Interdisciplinary Circular Economy Centre for Mineral-based Construction Minerals), covered the concept of Biodiversity Net Gain and how it is applied in practice to developments. It touched on the Biodiversity Metric and the advantages of a habitat-based metrics, as well as the limitations and how these can be overcome with case studies and lessons learnt from industry.

How CO2 mineralisation is driving the future of cement (17 March 2022)

By Dr Maciej Zajac from Heidelberg Cement

This brief lunchtime seminar, the Interdisciplinary Circular Economy Centre for Mineral-based Construction Minerals invited Dr Maciej Zajac from Heidelberg Cement to present a new approach to capture CO₂ and significantly reduce CO₂ emissions associated with cement production. This new carbon capture and utilisation (CCU) approach introduces a novel approach to CO₂ mineralisation of cement paste from recycled concrete. The feasibility of the process has been demonstrated at an industrial scale and, following further investigations into optimum carbon conditions and performance in novel composite cements, may be a game changer for industrial cement.
