The principle of selective deconstruction, in a logic of circular economy, is based on the desire to avoid waste and to manage in an optimized way the extension of the lifespan of products, equipment and materials, and to make the most of them. at the end of life. To ensure its success, the approach must apply to the successive stages of the construction sites, over the entire life cycle of the building, and involve all the stakeholders.
In order to support the sector in this virtuous path, the ORÉE Association and the Scientific and Technical Center for Building – CSTB, have published a dedicated guide: "Building sector: how to better enhance & deconstruct?" ".
Its purpose is to share good practices in order to support the necessary upskilling of the entire sector.
A practical and operational work, downloadable free of charge, today, here.
On the interest of selective deconstruction
More than 45 million tons of waste are generated each year by the building sector, compared to 30 million tons for all household waste. The reuse and recycling rates of these resources are currently well below their potential. In the dynamics of environmental transition in which the building is fully committed, it is important to modify practices to avoid this waste, improve the management of products, equipment and materials (PEM), throughout their life cycle, and enhance construction waste.
Selective deconstruction responds to this challenge: it makes it possible to increase the recovery of products, equipment, materials and waste (PEMD) generated during construction, through the reuse of PEMs and recycling, or any other material or energy recovery operation. , garbage.
The guide "Building sector: how to better value & deconstruct?" » provides the actors with the keys to understanding and apprehending this approach and the associated issues, and identifying the actions to be put in place to carry out a deconstruction operation.
A practical and operational tool
This new guide is a continuation of a guide produced by ORÉE, published in 2018. Beyond updating its key data, it reinforces the practical and operational dimension, providing players with the keys to implement selective deconstruction.
It is structured around synthetic and targeted methodological sheets:
- Action sheets: the key actions to be implemented to carry out a selective deconstruction project step by step, before, during and after construction;
- Job sheets: an approach by profession, listing the roles, missions and responsibilities of the main players involved in a selective deconstruction project (project management, project management, deconstruction company, PEMD diagnostician, waste managers, etc.);
- Sector sheets: inventory of recovery channels – reuse/recycling for SLDBs resulting from deconstruction and renovation;
“It is no longer a question of demolishing, but of deconstructing… to rebuild with the materials of deconstruction apprehended, not as waste, but as resources. It is a question of really applying the waste treatment hierarchy prioritizing reuse, reuse then recycling. This selective and thoughtful deconstruction approach is fundamental and can only succeed with the crucial involvement of all building stakeholders. This new guide, designed with the CSTB, aims to support them on this path, through methodological and operational tools. » - Patricia Savin – President of the ORÉE Association & Nathalie Boyer – General Delegate of the ORÉE Association
"The challenge today is to get out of the linear model extract-produce-consume-discard, to move towards more sober consumption and better use of resources, in particular by promoting reuse and improving the sorting of waste and its recycling. or their valuation. To support and consolidate these structuring changes, reinforcement, dissemination and appropriation of good practices are fundamental. This is the whole objective of this guide, which aims to provide players with the keys to move towards better management of products, equipment, materials and waste from existing buildings. The CSTB is happy to have co-managed its implementation, in partnership with the ORÉE association. » - Sylvain Laurenceau – Circular Economy Division Manager at CSTB & Camille Golhen – Circular Economy Project Manager at CSTB
