The circular economy is an economic model that aims to break away from the traditional “take, make, consume, dispose” pattern. It proposes rethinking the entire life cycles of products in order to minimize waste production and optimize the use of resources. Here are some key points to understand this concept, its challenges, its benefits, and its importance in the building sector:
What is the circular economy?
Closed loop of resources:
Instead of continuously extracting resources, the circular economy seeks to keep them naturally within a closed loop by promoting reuse, repair, renovation, and recycling.
The 3 Rs and beyond:
The model is based on the principles of Reduce, Reuse, and Recycle. It also extends to remanufacturing and energy recovery from waste.
Design and eco-design:
Products are designed to be more durable, repairable, and easily recyclable, thus limiting their end-of-life impact.
Challenges and benefits of the circular economy
- Waste reduction: By optimizing reuse and recycling, the circular economy helps limit the amount of waste sent to landfills or incinerated.
- Preservation of natural resources: By recovering end-of-life materials, it reduces the need to extract new resources, thus contributing to environmental preservation.
- Job creation: The establishment of recycling, repair, and reuse streams creates new economic opportunities and local jobs.
- Innovation and competitiveness: This model encourages companies to innovate in their production processes and resource management, which can strengthen their competitiveness in the market.
- Reduction of CO₂ emissions: By promoting the reuse of materials and reducing the extraction and processing of resources, the carbon footprint linked to production can be significantly reduced.
Why is this important for the building sector?
The building sector is one of the main consumers of natural resources and a major generator of waste (construction waste, demolition waste, etc.). Here is why the circular economy is particularly relevant for this sector:
- Material optimization: The adoption of eco-design in construction makes it possible to design modular buildings that are easy to dismantle and whose materials can be reused or recycled at the end of their life.
- Waste reduction: By promoting the reuse of materials from demolition or renovation, the sector can significantly reduce the amount of waste sent to landfills.
- Innovation in construction: Circular approaches encourage the development of more sustainable construction techniques, such as modular construction or the use of recycled materials, which can reduce the overall environmental impact of the building.
- Energy transition: The circular economy in the building sector is part of a broader ecological transition approach, making it possible to reduce the sector’s carbon footprint and promote more responsible practices.
In summary, the circular economy provides a framework to transform the way we use resources, emphasizing sustainability and efficiency. In the building sector, it represents a major opportunity to reduce environmental impact, preserve resources, and encourage innovation, thus contributing to a transition towards a more environmentally friendly development model.
Priority missions: Prevent / Collect / Treat
Targets for reuse / repurposing have been established, by setting a reuse/repurposing rate relative to the estimated waste stream.
Eco-organizations deploy action plans to achieve these objectives, including for example calls for projects to support construction sites or develop new reuse activities, support contracts for reuse stakeholders, the drafting of technical guides or standards, etc.
Reuse zones will be created at collection points.
Finally, bonuses and penalties have modulated eco-contributions since 2024, in order to favor products and materials placed on the market that have better environmental performance.

Treatment
It is estimated that approximately 80% of BCPM waste is collected directly on construction sites and 20% is deposited at collection points such as public waste disposal centers, professional waste disposal centers, distributors, and inert waste platforms.
Eco-organizations have deployed a network of collection points. They must ensure there is a point every 10 or 20 km that accepts all waste streams, including hazardous waste for half of these points (also called “mesh points”).
Beyond a certain quantity of waste, eco-organizations also collect waste from construction companies and at construction sites.
Collection
Category 1 waste (mineral) is directed toward the following types of treatment:
- Reuse/reutilization (less than 1%)
- Recycling: production of recycled aggregates, mainly for road construction projects (33% estimated in 2019 in the preliminary study)
- Material recovery: quarry backfilling, on-site or at another construction site (43%)
- Disposal: storage in inert waste storage facilities (IWSF) (23%)
Category 2 waste is directed toward the following types of treatment:
- Reuse/reutilization (less than 1%)
- Recycling (37%)
- Energy recovery (8%)
- Disposal: storage in non-hazardous waste storage facilities (NHWSF) or incineration (54%)
Hazardous waste is disposed of: storage in hazardous waste storage facilities (HWSF), asbestos storage facilities, or hazardous waste incinerators.
The regulations define 2 different categories for the BCPM sector:

- Fired or unfired clay;
- Slate;
- Bituminous mix or contributing to the preparation of bituminous mix, excluding bituminous membranes;
- Aggregate;
- Ceramic.
Category 2
Other construction products and materials belonging to the following families:
- Construction products and materials consisting predominantly by mass of:
- Metal;
- Wood;
- Plaster;
