FCRBE - Facilitating the circulation of reclaimed building elements in Northwestern Europe

Project Summary

Today in NW-Europe, only 1% of building elements are reused following their first application. Although a large number of elements are technically reusable, they end up being recycled by crushing or melting, or disposed. The result is a high environmental impact and a net loss of economic value.  

This project aims to increase by +50%, the amount of reclaimed building elements being circulated on its territory by 2032.

Focusing on the northern half of France, Belgium and the UK, the project also covers, with a lesser intensity, the Netherlands, Ireland, the rest of France and Luxembourg. This area houses thousands of SMEs specialised in the reclamation and supply of reusable building elements. Despite their obvious potential for the circular economy, these operators face significant challenges: visibility, access to important projects and integration in contemporary building practices. Today, the flow of recirculated goods stagnate and may even decrease  due to a lack of structured efforts.

To respond appropriately to these challenges, the project sets up an international partnership involving specialised organisations, trade associations, research centres, an architecture school and public administrations. It is rooted in earlier initiatives that were successfully initiated, on a local level.

The project will deliver:

  • 1 online directory that richly documents more than 1500 specialised reuse operators,
  • 1 pre-demolition audit method for reusable elements,
  • a set of 4 innovative specification methods for reclaimed products,
  • and more!

These tools will be tested and promoted through 36 pilot operations taking place in large (de)construction projects, whereby more than 360 tons of elements will be reused. Effective communication efforts towards the stakeholders of the construction industry (including public authorities) will facilitate a smooth integration of these outputs into field practices and policies.

2020/10/07: Workshop in Brussels on the pre-demolition audit

, Brussels

The FCRBE guides has been tackled during a Workshop organized by the Reuse Platform here in Brussels on the pre-demolition inventaries. The objectives of this event were to understand where the actors in the construction industry stand in the implementation of inventories with the aim of reusing building materials in their projects and to understand the obstacles they've met during its realization. This discussion also took place in order to define the place of this reuse-inventory in the framework of waste-related inventories. The FCRBE manuals are not presented in details during this workshop. The organisers of this event assumed that the participants were professionals already familiar with these tools.

The project was made possible with the support of our co-financing partners :

The Digital School of Re-construction (Digi-SoR-c) summer school ran for two weeks from Monday 2nd -13th August 2021.

Thank you to everyone who took part in the digital School of Re-construction Summer School. We feel that it was a fantastic success with a huge output of creativity and inspiring ideas from both students and Team Leaders alike. It is now our intention to capture the outputs from the Summer School in the form of a book and perhaps some other digital publications. So if you took part in the Digi-SoR-c we will be in touch about these exciting developments very soon. If you want to know more please contact project co-ordinator Duncan Baker-Brown at D.Baker-brown@brighton.ac.uk


The University of Brighton’s School of Architecture and Design are hosted a digital Summer School aimed at students from the worlds of design, architecture, construction and engineering. The digital School of Re-construction (SoR-c) considered concepts and propositional ideas that considered ways to re-use materials and elements from the built environment.

Our team at the University of Brighton includeds Anthony Roberts, Nick Gant, Dr Ryan Woodard, Siobhan O’Dowd and was led by senior lecturer and architect Duncan Baker-Brown best known for coordinating the building of the Brighton Waste House, “Europe’s first permanent building made of materials other people discarded”.

The SoR-c team were joined (online) by partners from across North-West Europe*, including re-use experts Rotor from Belgium, and Bellastock from France, who are deconstructing the 59-storey Montparnasse Tower in Paris.

The School of Re-construction is part of an EU ERDF €4.33million Interreg NWE project entitled, ‘Facilitating the Circulation of Reclaimed Building Elements’ (FCRBE) which runs from 2019 to 2022. It will deliver, among others:

  • An online directory of more than 1500 specialised salvage dealers and allied businesses in North-West Europe.
  • A pre-demolition 'tool kit' designed to help clients assess the re-use potential of materials and products present in buildings slated for demolition.
  • A specifications manual to help construction professionals integrate reclaimed building materials and products in large-scale projects.
  • Test and promote tools through 36 pilot operations taking place in large (de)-construction projects across North-West Europe.

This project responds to the worldwide declaration of Climate and Ecological Emergency, and locally to Brighton and Hove’s ambition to be Net Carbon Neutral by 2030.

*North-West Europe includes Ireland, United Kingdom, Belgium, Luxembourg, France, Germany, Switzerland  and the Netherlands.

Topic 2021: Re-think Re-Use

Digital School of Re-construction 2021

Over 70 students from different regions across the world worked in teams with designers and makers to re-think and re-use, through the re-construction of disassembled materials, to create a series of thought-provoking digital design interventions, that endeavored to prove that “there’s no such thing as waste, just stuff in the wrong place!”

Drawing on the partners and work of the Interreg FCRBE project the Summer School included discussions and debates on topics relating to urban mining, resource mapping, deconstruction, re-use, and buildings as material banks.

Drawing from their immediate environment’s, each participant surveyed a chosen artefact, room, or building with a view to digitally unpacking and deconstructing them. Each of the eleven teams created their own digital library; to be shared, interrogated, understood and re-imagined as a ‘new’ proposition.

Since the rise of modernity, design usually precedes construction. Consequently, designers generally develop their projects around standardized, stable and predictable construction products or they order specialised production of bespoke elements that will match their requirements. In essence, reclaimed products are the exact opposite of this: they are largely heterogeneous, unpredictable, and situated. In this sense, they question the habits of designers.

We tackled this question by challenging each team to design and realise a small construction out of reclaimed elements in response to one of the workshop themes as detailed below.
These themes posed questions and provided a particular ‘lens’ for re-structuring elements that are usually discarded or re-worked. Each team had an array of digitally reclaimed elements sourced from across the Interreg FCRBE region to choose and experiment with.

All these realisations are small living laboratories that allowed one to have direct experience with these challenges. The two-week-long workshop culminated in a carefully curated online exhibition of these experimental design interventions.


The following themes were read as specific ‘lenses’ through which participants looked at their particular ‘libraries of elements’. Please note that in some cases they were slightly adapted depending on what was surveyed and collected by each of the teams taking part.



Theme 1 THE RAW:

The aim of re-use that will be explored, is how to effect a new condition by NOT altering, or ‘re-cooking’, the materials gained by reclamation. By working with the dismantled elements in their ‘raw’, or unaltered form – what are the possibilities of reconfiguring them into new, spatial and material combinations?

Theme 2 THE ‘USELESS’:

Materials deemed ‘useless’ are often cheap, can be found in abundance and as a result, are often discarded as not worthy of consideration. How can we make these rejected elements useful and desirable for construction?


Materials that exist as a by-product of conventional modes of production can often be overlooked and ignored. How can they become one of the re-fashioned and delivered as a newly envisioned focus that supports the act of re-use?


Systems and materials are often standardised and configured in conflicting or unaccommodating arrays of sizes and shapes, which generates more waste. How can they be combined to create new, workable relationships through the crude use of montage?

Theme 5 THE ‘OFF-CUT’:

The off-cut is notoriously known for being ‘not quite long enough’. By only utilising these awkward materials the question again arises, how can these usually discarded elements be re-examined and re-combined to form workable structures and envelopes that might not conform to the notion of the standard?

FCRBE tools (online directory, inventory and prescription guides) have been tested and promoted through 37 pilot operations taking place in (de)construction projects of different sizes and types, whereby elements are or will be reused.

Two kinds of pilot operations have been carried out:

  • extraction: extracting a batch of materials from a demolition site towards reuse sectors.
  • integration: integrating reuse elements in a construction or rehabilitation project at the design or tendering phase

In this page, you will find an overview of each pilot project. For each pilot project, you can download a fact sheet (pilot report) that documents the operation individually.

Petite Île / City Gate, Brussels (extraction)

A decommissioned industrial site to be reanimated into a lively neighbourhood


This site, formerly dedicated to various industrial activities, will be brought back to life to host a neighbourhood with a high social and programmatic diversity. The site developers have a high target regarding circular economy issues and aim at using as much materials from the former buildings to be demolished into the new ones.


How to take into account the site history wherein seemingly homogenous buildings were actually built and modified at different periods with different materials ? How to ensure that the inventory reflects this reality in order to estimate the actual quantity of materials that can be reused ? How to implement this issue into the deconstruction process ?

Upgrading of 3 social housing apartments


AGSL renovates 3 studio apartments with a limited budget in a social housing apartment complex at Fonteinstraat. In cooperation with the architect, reuse possibilities of the available materials were looked for in order to integrate them in the project of renovation. Insulation and ventilation is foreseen for the complex and 3 different approaches were planned for the apartments: from Low key to High key, based on the intensity of the spatial redesign and the reuse intensity.


How to create a quality home responding to today's standards with a limited budget? How to find sites where to reuse the extracted materials of very low value? How to take into account the existing structure, technical equipment and facade of the apartment complex? How to respond to the ambitions of the developer and architects regarding circular economy within the economic constraint?

Extension of an office building from SPW, Malmedy (integration)

Late introduction of reused elements in the context of a constrained public tender.


Increase of the re-use rate in the context of the transformation and extension project of an office building owned by the Public Service of Wallonia, Department of Agriculture, Branch of Malmédy. Preservation of the existing building structure and construction of new buildings to significantly increase the capacity, comfort and accessibility of the offices.


The project was developed without the ambition of reuse. The search for ways to extract and reuse materials on site, or to integrate elements available on the market, comes late in the process. It is necessary to find a way to concretise this new ambition, in a rather constrained public market context, and although the potential for reuse on site seems low.

De Ideale Woning, Lint (extraction)

Feasebility study of  reuse of bricks and roof tiles 


Social housing organization De Ideale woning is demolishing 28 houses. The houses will make way for a park, but after a few years new social housing and private houses will be built within a new complex. The houses were built in different periods and are in poor condition. The amount of material is high but the quality of the bricks is uncertain.   


Is it interesting for the developer to carefully disassemble, stock the materials for a long period of time, test their quality and recondition them in order to reuse them in the new buildings? Can these materials pass the quality tests and offer the same guarantee as new ones? Can all these operations compete with the very low price of new materials? How to take into account the uncertainty of the future site planning?

Belgrade, Brussels (extraction)

A tram workshop as a basis to develop a company-wide practice


This former tram workshop, owned by the Brussels public transports company STIB, is to be refurbished  for mixed purposes, with mainly technical, sanitary and heating equipment to be evacuated. The loose schedule with works starting in 2024 enables to explore various potential  solutions for the reuse of these materials and to take the time to learn from the experience to replicate the process on future works on other sites.


Is there a potential for internal reuse for the specific technical equipment ?  How to find potential buyers or recipients for the equipment which cannot be reused internally ? How to transform the knowledge and experience from a pilot operation into a company-wide practice applied on all refurbishment projects ?

It was,  therefore  keen  to  explore  suitable  reclamation pathways   for   identified   materials   and   with   the support  of  the  dealer  network  and  FCRBE  toolkit, look  to  same-site  and  inter-site  reuse  wherever possible.
