Making a good inventory (by Buildwise)


A good inventory is the starting point for high quality recycling and reuse for a demolition project. Learn all about inventories in this illustrated booklet. Buildwise gives insights on

  1. How are inventories made?
  2. What is the difference between the demolition and the reuse inventory?
  3. Why are they useful for circularity?
  4. What do they look like? A
  5. Are there digital tools which can help make inventories?

Manifesto on circular economy in building industry


Partner of the Digital Deconstruction project which aims to develop the circular economy in the building industry, GreenFlex wants to be one of the catalysts for ever more resilient approaches in this sector. Together with the French partners of the program, AREP, Vilogia, NOBATEK/INEF4 and SNCF Gares & Connexions, they have developed the Manifesto for a circular (de)construction, support to share with you their vision of the sector, and their understanding of the levers to be activated to massively use reuse in the building sector. You can download this Manifesto and learn more about their ambitions and ambitions of the Digital DeConstruction program, Interreg North West Europe (NWE) project, visit the brand new GreenFlex website!

Circular Deconstruction Handbook


Handbook Circular Deconstruction. The Handbook is the result of a user’s working method, in which the following processes of the Property Owner – Pilot Owner are supported based on daily experiences and with the aid of various aid documents, tools, methods and techniques such as .

The Handbook describes the details of the processes and the associated documents, experiences, questions, and answers for each part of the process in 12 steps which we adress in the Handbook itself. This results for each process component in a template for the property owner – project owner, with which each process component can be completed. A script for every sustainable demolition project.

General protocol for the development of deconstruction and reuse strategies and undertaking deconstruction at pilots (Using DDC tools)

This document, deliverable of the DDC project, guides stakeholders :

  • in the use of DDC tools and platform,
  • in the Deconstruction and reuse process with rules and tips from DDC partners based on their experience in DDC pilot projects



DDC State of the Art on digital tools for Urban Mining

Digital products, services and tools supporting the recovery of building materials sourced from deconstruction operations This report consists in a review of digital products, services and tools already available in the market or in development that support the recovery of building materials sourced from deconstruction operations. Every product, service or tool is briefly explained with the help of information such as used technologies, explanation on how the products can help the recovery of reclaimed product, etc. This review does not pretend to be exhaustive, but hopes to give an overview of what new digital technologies can bring to the world of repair, reclaim, reuse and recycle.

Overview results of the first survey (2020) on DDC

In 2020, an online survey was conducted to obtain a view on the end-user needs in terms of digitalisation, demolition, reuse and recycling. More than 200 answers were received, coming from Belgium, the Netherlands, France and Luxemburg. In this report (ENG), project partner Buildwise (formerly BBRI) presents an overview of the results of this survey. This was the first deliverable of the DDC project.

Case studies (in Dutch and French) from project partner WTCB-BBRI

4 case studies elaborated on the use of digital technology for urban mining & reuse made by project partner WTCB-BBRI (B).

Flexible Real Estate with Blockchain

In this book we look behind a circular and sustainable application in materials in and for buildings. A special role is assigned to the use of modern technologies and for blockchain technology. The book answering about the issue of circularity itself. It deals with the regulations, the technological possibilities and influencing behaviour.

The toolbox used in the book contains tools from the combination of law and economics to build a path for everyone in such a way that the people involved automatically walk in the right direction. Read the book to see, how this can be done.

BIM For Urban Mining

Is Building Information Modeling the digital tool for Urban Mining? Project partner BBRI (B) has made an article on this, now also available in Dutch and French. Find the NL en FR articles below.

Development of a conceptual digital deconstruction platform with integrated Reversible BIM to aid decision making and facilitate a circular economy

Construction and demolition waste accounts for about 33% of all waste within the EU. Circa 50% of this amount is currently recycled in most EU countries, however, the majority of waste is destined for backfilling and other low value applications. Poor knowledge of material and product composition, building reversibility, disassembly capacity of buildings and poor digitization of the construction sector are factors hindering better exploitation of multi-layered capacity of buildings and their circular opportunities. A highly digitalized deconstruction process (using digital tools to support inventory, strategies for material recovery and planning of deconstruction process) can contribute to a circular built environment, bringing key enabling technologies on digital deconstruction platform to be exploited, such as: Building Information Modelling (BIM), scan-to-BIM methods, materials’ databases, blockchain, and most importantly method for reversibility assessment of existing building and its components (Durmisevic, 2009) integrated in BIM (so-called Reversible BIM). This paper presents the ongoing developments for the integration of a reversibility assessment method within a larger scope deconstruction platform.

Minor Training Circular Demolition – Building a sustainable future

Welcome to the minor course Circular Demolition! In this minor we take a closer look at the principles of circular demolition and the importance of sustainability in the construction sector. During this training we will focus on some essential topics that form the basis of a circular approach in the demolition industry.
