The aims of the project
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. By linking the digital system to innovative Building Information Model techniques, a cycle is created between design, construction and demolition. Scarce resources are reused in this way and will drastically reduce the huge CO2 emissions of the construction industry. Researchers within the project are working on this open-source software system so engineers can reuse materials released from the dismantling of renovation and demolition projects in the construction industry and create a more sustainable future. The project focuses on regions having set sustainable materials management, ecotechnologies, ICT and digitization in industry as one of their RIS3 priorities in The Netherlands, Belgium, Luxembourg and France, paving the way for roll-out to United Kingdom and Denmark. 

Project Outputs
The project developped the following main outputs:

  1. An integrated DDC system at TRL7, to be made accessible to companies in IT, engineering, construction & real estate sector as an open-source software package for further development and integration to market-ready products and services. See the knowledge platform for the information on the navigator and the integrated DDC system.

  2. A transnational network of Regional Innovation Hubs (RIH) that support the optimization, validation and roll-out of DDC solutions. 
  3. Pilot sites are a crucial part of the DDC project, as they aim for a real field application of the research, development and strategies created during the Digital Deconstruction project. As part of the Interreg project Digital Deconstruction, 5 pilot sites, located in the 4 cooperative countries, were chosen to implement the work that has been carried out by digital tools developers and all the other partners inside the ecosystem, experiment new ways to create strategy maximising reuse thanks to the help of the DDC System, and gather feedbacks from field application. Here the 5 sites in the 4 partner countries are detailled. 

Background of the project

Construction and demolition waste (CDW) accounts for about 1/3 of all waste produced in the EU. About 50% of this amount is currently recycled in most EU countries, however the majority of CDW is destined for backfilling and other low value applications (downcycling). In North West European countries reuse and high-quality recycling (upcycling) of CDW remains below 3%. ​​Poor digitalization of the construction sector is one of the key factors hindering better exploitation of circular opportunities.

Can high-quality reuse and recycling of building materials make construction more efficient (and again cheaper)?

Posted on

In recent weeks and months there have been few positive sounds from the construction sector. Material prices have been rising for some time and the war in Ukraine has exacerbated this trend. Russia, Ukraine and Belarus are major exporters of timber and steel under normal circumstances. In addition, many factories in Europe are voluntarily scaling back their production because of high gas and electricity prices, and raw materials or by-products for the production process largely come from the current war zone. This puts the sector's profitability under severe pressure. Read More

February 3: Theme session RIH (B) on BIM for urban mining in demolition sites

Posted on

How is BIM useful in demolition sites? Can it help reuse and recycle materials and demolition waste ? To answer these questions, The Belgian Innovation Hub invites you to an interactive webinar where experts will present the use of BIM on circular demolition sites. The ZOOM session on February 3, 2022 is free and has a lively interaction. Presentations will be in French and Dutch. Read More



The results of the project can be tested and demonstrated on 5 pilot sites, in the 4 cooperative countries, organized by one of the project partners, who is also the first contact for the pilot owner.

Each pilot owner must be able to set up the pilot on the basis of a manual en be able to make use of the present technological tools that are available at that time. These pilot owners are also supported in the process of demolition of buildings when using these instruments.

The manual for each pilot will be updated along the process of the pilot, the use of tools and the way of working. The pilot results can be used in the Regional Innovation Hubs.

3D scanning Hof Ter Laken (B)

On Thursday 29th of April 2021 the scanning of the castle, horse stables and barns of Hof Ter Laken, situated in Booischot (Heist-op-den-Berg) in Belgium. Project Partner BIM-Y made the scans. The architectural office received the data in June and is currently reviewing and evaluating it. At the end of 2020, project partner Kempens Landschap already had 3D scans of the buildings performed by another company, so it will be very interesting to compare their data to the data from BIM-Y in terms of quality and detail. In this way a useful evaluation can be made.

In this way a useful evaluation can be made. 

The next step is to see whether the 3D scans can be used for drawing up floor plans, cuts, etc. so that the demolition file can be drawn up more easily. It will also be examined whether it is possible to establish a digital link to certain elements that will be sold online, for example, on the basis of the digital copy that is now available of the buildings. 

Two barns behind the stables/depot will be deconstructed in the winter of 2021-2022. Or at least that's what they are planning for now. If the administrative procedures run out, it will be the spring of 2022. 

The interior of 1 part of the depot will also be deconstructed in that period. The other buildings on the domain will be preserved and will be restored in the coming years, preserving their heritage value. 


See the video of the scanning of this beautiful monumental castle and barns. Dutch spoken.


3D scanning Vilogia (Fr)

Digital Deconstruction 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 a digital decision support system, integrating various digital tools. One of these tools is the 3D scanning of the buildings; it was tested on pilot sites in France, Luxembourg, The Netherlands and Belgium.

On June 15th in Norther France, in Lomme, city located in Lille Metropolitan Area, the 3D scanning was performed by project partner BIM-Y on Vilogia’s pilot site. The scan will illustrate the various states of the dwellings, depending on each dwelling particular story. 

Vilogia: “We scanned a residential building where 7 dwellings over 16 are still occupied. The scan was done in the unoccupied dwellings (9 over 16) and the external parts of the building. The outcome of the 3D scanning is quite impressive! We can virtually visit the dwellings and see their current state. The next step is to test the other modules for the digital software platform. 

When is/will this building be demolished, or will not be demolished?  
It should be deconstructed in 2022, depending on the administrative procedures that have to take place"  


3D scanning Roman Museum Heerlen (NL)

On monday 5th of July 2021 the Roman Museum in Heerlen was mapped with a 3D scanner by project partners GTB Lab (NL) and BIM-Y (LU).

On Monday 5 July 2021, the building of the Thermenmuseum (Roman Museum) Heerlen in the Netherlands was mapped with a 3D scanner. The building, which will be completely demolished, is one of five pilot projects within the Interreg North-West Europe subsidy project Digital Deconstuction (DDC). Under the leadership of the Province of Limburg, 14 European project partners from France, Belgium, Luxembourg and the Netherlands are developing a digital software platform that can define materials in buildings for reuse and enable circular construction.

Manifesto For Circular (De)Construction

This manifesto was produced by researchers at the Luxembourg Institute of Science and Technology (LIST), as part of the INTERREG NWE Digital Deconstruction project (Advanced Digital Solutions Supporting Reuse and High-Quality Recycling of Building Materials), a project funded by the European Regional Development Fund and co-financed by the Ministry for the Environment, Climate and Sustainable Development.

This manifesto aims to present initiatives in the field of deconstruction and construction in order to encourage a range of good practices and develop activities relating to the circular economy in Luxembourg. It envisages a more rational management of resources, giving priority to the prevention and reduction of waste through the reuse and optimal recovery of building components resulting from deconstruction.

Explanation on the test sites for the DDC modules

Click the video in which our French project partners Greenflex, Vilogia and AREP explain how the pilots were a perfect test site for the modules of the digital deconstruction system. The modules integrated in the digital decision software help building, design and demolition companies to scan, trace and store materials which can be reused in new building projects. The video was made after the final event where all partners gathered for presenting the last results on the development of the DDC digital decision software system for a more circular building industry.

Circularity, a priority in the renovation of

The project aims to transform the Fritz Toussaint barracks in Ixelles into a dynamic site. This renovation project set very high standards in terms of sustainability, while also adopting a circular demolition strategy using BIM.

Enhancing circular demolition through digitalization.

Significant advancements are underway in the field of circularity. In late May, approximately 100 participants gathered at the headquarters of Buildwise, formerly CSTC-WTCB, to witness firsthand how they could more effectively commit to a circular demolition strategy. Undoubtedly, digital tools already exist, as evidenced by the Interreg Digital Deconstruction pilot projects. It’s now imperative to gradually integrate these tools into our own way of working.

The newsletter is in English, Dutch and French.

Report of a study on digital trading platforms

Reuse of building materials is one of the key points of circular economy in the construction sector. However, offer and demand of reused materials do not always meet. To facilitate the circulation of these materials, several digital trading platforms have been developed across North-Western Europe.

To get a better view of this burgeoning market, a study was pursued within the framework of the Digital Deconstruction Interreg project. A total of 41 platforms were analysed and several interviews were conducted.

Read the report of this study, as well as a short summary containing the list of platforms analyzed.

BIM based inventory to prepare a circular demolition

Sustainability and digitization go hand in hand and are gaining popularity. Digital tools are proving their usefulness in achieving high circularity in both the construction and demolition industries. Lionel Bousquet of BXLMRS Architects applied a BIM model to create a digital inventory of all materials in the CCN (Communication Center North), which enables circular demolition.

Réemploi des matériaux : ces projets qui émergent en Ile-de-France

Bruno Mouly |  le 16/09/2022  |  Réemploi des matériaux,  Economie circulaire,  Ile-de-France

Ma newsletter personnalisée

La deuxième édition du Hub d’Innovation du Réemploi organisé le 15 septembre par Greenflex à Paris, a mis en évidence divers projets et opérations d’économie circulaire dans le bâtiment.

Avec la production de 41 millions de tonnes (Mt) par an de déchets de matériaux de construction, dont 51% sont issus de la démolition des bâtiments (21 Mt), 36% de leur rénovation (15,1 Mt) et 13% de la construction neuve (5,6 Mt), l’économie circulaire dans le bâtiment a une importante marge de progression lorsqu’on sait que moins de 1% de ces déchets sont réemployés.

De multiples projets de réemploi commencent de fait à se développer en France et en Europe. « Le projet européen Interreg Nord West Europe Digital Deconstruction, qui regroupe 14 partenaires européens dont les français Vilogia bailleur social, l’Arep l’agence d’architecture pluridisciplinaire, SNCF Gares & Connexions et Greenflex, a l’ambition d’aider au développement d’une filière de réemploi en agrégeant la demande et en améliorant la qualité de l’offre » a indiqué Sébastien Delpont, directeur conseil chez Greenflex.

Les partenaires de ce projet (dont les Français qui hébergent les sites pilotes dans l’hexagone) ont l’objectif de systématiser le réemploi des matériaux lors de la déconstruction des bâtiments. Le programme s’articule autour d’échanges sur les pratiques et sur la mise en commun des connaissances des acteurs du secteur. Il soutient le développement d’outils digitaux facilitant le réemploi et la déconstruction sélective et s’attache à tester ces outils sur 5 chantiers pilotes de déconstruction de bâtiment pour évaluer leur pertinence et améliorer leur développement en fonction des besoins. « Le numérique doit servir d’outil d’aide à la décision aux stratégies de déconstruction » a-t-il souligné.


L'Ile-de-France en pointe


En France, les projets se multiplient tous azimuts. Plaine Commune, communauté de 8 communes de Seine-Saint-Denis, s’engage dans l’économie circulaire du BTP à l’échelle de son territoire. « Notre projet vise à généraliser le réemploi des matériaux sur l’ensemble des programmes de démolition, de réhabilitation et de construction de bâtiments sur la base des exigences d’une charte d’économie circulaire et d’une boîte à outils qui permet de sourcer les matériaux de réemploi » a précisé Justine Emringer, cheffe de projet Métabolisme urbain de Plaine Commune. Ainsi, la réhabilitation de la friche Badcock à la Courneuve a permis de récupérer des briques pour la maçonnerie paysagère d’une ferme agricole urbaine à Stains. Et sur le chantier d’Icade Pulse à Aubervilliers, on a réemployé les dalles de faux planchers.

De son côté, Est Métropole Habitat « a récupéré et valorisé 2 600 m2 de parquet en chêne massif dans la réhabilitation de la friche urbaine l’Autre Soie à Villeurbanne (Rhône) » selon Paul Sachot, son chargé de mission Expérimentation.

Enfin, dans la transformation de l’ancien siège d’Airbus à Suresnes (Hauts-de-Seine) en résidence étudiante, commerces et bureaux dont une partie sera livrée en février 2023, Vilogia va réemployer in-situ et hors-situ, 1 000 m2 de pierres de façade, 150 m de cloisons vitrées, 1000 m2 de faux plafonds, 110 stores et 1300 m2 de faux plancher. 





Press release on Hof Ter Laken (B)

Project partner Kempens Landschap has one pilot project in Belgium, Hof ter Laken in Heist-op-den-Berg, where various materials out of the old castle, horse stables and barns are scans and tested for recycling. The two barns behind the stables/depot will be deconstructed. The interior of 1 part of the depot will also be deconstructed in that period. The other buildings on the domain will be preserved and will be restored in the coming years, preserving their heritage value. More information on this pilot project, read enclosed press release (in Dutch).

This is the moment for circular building

In the Dutch newspaper De Limburger an interview with Elma Durmisevic and Thomas Bergstra was placed on circular building.

Everybody talks about circular building, but it doesn't exist yet. Now is the moment to start with circular building in Parkstad Limburg as the task on construction and deconstruction is now economically interesting, says Elma Durmisevic from Green Transformable Building Lab in Heerlen.

Regional Innovation Hubs

The Regional Innovation Hubs (RIHs) bring together industry frontrunners and other parties interested in digital tools for reuse and high quality recycling. These networks allow participants to explore possibilities to use digital technology for urban mining – through demonstrations, explanations, hands on testing and practical use cases. Members of the Hubs will also discover first-hand the innovative digital tools developed by the Digital Deconstruction project and share experiences with other frontrunners in the sector.

In each of the four countries participating in the Digital Deconstruction project is set up a Regional Innovation Hub (RIH) : Belgium, France, Luxemburg, and the Netherlands.

The Regional Innovation Hubs reach out to general and demolition contractors, architects and consultants, public or private clients interested in circular economy, software developers, and stakeholders in the reclamation and recycling industry. The RIHs have the objective to create and coordinate a network of deconstruction actors interested in digitalization. Within the network, participants are empowered to start new projects and develop their skills and knowledge.

A Transnational Hub is also set up to allow frontrunners to dive deep in the technological developments of the Digital Deconstruction modules, and share on transnational issues, creating a network for future developments of DDC tools.

Would you like to get hands-on experience with innovative digital tools for urban mining and discuss your experience with industry pioneers?
