Wood, Plaster and the Price of Waste: What France’s New Rules Mean for Builders’ Merchants

If you sell building materials in France, your waste costs are about to change. A new French law splits building waste into two groups. Some materials, like wood and metal, will soon cost money to throw away. Other materials, like plastic and glass wool, will get free recycling support. This means the prices you pay and the advice you give to builders must change.

On 19 February 2026, Mathieu Lefèvre, the French Minister Delegate for Ecological Transition, announced the final decision to overhaul the country’s extended producer responsibility scheme for building products and materials, known as the REP PMCB [1]. This decision followed nearly twelve months of intense consultation with industry stakeholders [1]. The reform introduces a structural division that will fundamentally alter how building materials are priced, sold, and disposed of across mainland France, though the rules will not apply to France’s overseas territories [1].

Under this new framework, the French government divides construction materials into two distinct categories: “mature” and “non-mature” [1, 7]. Mature materials include inert substances, metal, wood, and, in the short term, plaster [1]. The Ministry of Ecological Transition determined that these sectors already possess self-sustaining recycling markets and do not require financial support from producer responsibility organisations, known as eco-organisms, to facilitate recycling [1, 7]. Conversely, non-mature materials (such as glass wool, plastics, glazed joinery, and bitumen membranes) require active financial support to build and maintain their recycling infrastructure [1, 7].

This operational framework is managed by four approved eco-organisms: ECOMINERO, ECOMOBILIER, VALOBAT, and VALDELIA [7]. These organisations were approved in October 2022 and began implementing the REP PMCB sector in 2023 [7]. The 2026 reform represents a major course correction for these organisations, shifting their financial focus away from mature materials to concentrate resources on developing sectors [1, 7].

For procurement directors, the immediate challenge is managing the financial transition. The four eco-organisms announced tariff scale increases that took effect on 1 July 2026 for three of the organisations, and on 1 August 2026 for Ecominero [2]. These sudden increases highlight the volatility of waste-related overheads. To prevent future price shocks, the February 2026 reform establishes a mandatory nine-month notice period (délai de prévenance) for any changes to upstream and downstream tariff schedules [1, 3].

This notice period is a vital commercial shield for builders’ merchants. It ensures that manufacturers and eco-organisms cannot raise fees overnight, giving distributors the necessary time to calculate their landed costs, renegotiate purchasing agreements, and adjust their trade price lists. In a low-margin sector, a nine-month window to adapt to regulatory cost increases can preserve a merchant’s profitability.

The most significant operational disruption will occur at the end of 2026. The French Ministry of Ecological Transition directed that free take-back services for sorted small waste volumes (defined as up to three cubic meters or within a 1.5-tonne limit) will only be maintained until 31 December 2026 [4]. This temporary measure was designed to ease the transition, but its expiration creates a sharp deadline for merchants and their contractor customers.

Starting 1 January 2027, subject to the final publication of regulatory texts, the free collection of sorted waste will end entirely for mature material sectors, including inert materials, wood, metals, and plaster [2]. Contractors who are accustomed to dropping off these heavy materials for free at merchant yards or collection points will face new disposal fees. Distributors need to prepare for the reaction of trade customers who suddenly face fees to dump plasterboard. Merchants must prepare to explain this shift to their customers, as the financial burden of disposing of mature materials moves back to the trade.

Conversely, also starting 1 January 2027, treatment costs for sorted waste will be fully covered for developing, non-mature sectors [2]. This means that complex, hard-to-recycle materials like glazed joinery, plastics, glass and rock wool, and bituminous membranes will benefit from subsidized or free treatment when properly sorted [2]. This creates a powerful incentive for merchants to establish dedicated sorting zones in their yards. By helping contractors sort and return non-mature materials, merchants can position themselves as cost-saving partners.

However, some regulatory uncertainty remains. According to the French Construction Federation (FFB), the current REP system remains in force for all waste, both mature and non-mature, until 31 August 2026 [2]. The draft decree modifying the REP PMCB is scheduled to enter into force on 1 September 2026 [7]. Furthermore, trade publications indicate that the final application and regulatory texts for the overhaul are expected at the end of August 2026, meaning the precise modalities and tariff impacts are still to be confirmed [3, 4].

Despite this uncertainty, some eco-organisms are already projecting major tariff drops for certain categories. Valobat, which reported a treated waste volume of approximately 161,000 tonnes per month in April 2026 (published on 27 May 2026) [4], predicts a drastic reduction in eco-contributions for mature materials starting 1 January 2027 [4]. Valobat aims to at least divide its current rates for these materials by two [4]. This potential reduction in upstream eco-contributions could lower procurement costs for wood and plaster, offsetting the loss of free downstream waste collection.

Compliance is no longer a secondary concern for procurement teams. To enforce the new rules, a government amendment to the DDADUE bill, adopted by the French Senate, strengthens sanctions against eco-organisms that fail to meet their recycling targets [1]. Crucially, the amendment also targets non-contributing companies that attempt to bypass the system [1].

This regulatory tightening coincides with the introduction of new eco-organism accreditations starting 1 January 2027 [3]. For merchants, this means that buying from non-compliant manufacturers carries severe operational risks. If a supplier fails to pay its eco-contributions or loses its accreditation, the merchant could face supply chain disruptions or even legal liabilities. Procurement directors must audit their supplier lists to ensure every partner is fully registered with an accredited eco-organism.

The bifurcation of waste economics in France requires a complete rethink of product ranges and supplier relationships. Merchants can no longer treat waste disposal as an afterthought; it must be integrated directly into procurement decisions.

First, review your inventory mix. Non-mature materials like plastics and bitumen membranes will become cheaper to dispose of if sorted correctly, while mature materials like plaster and wood will carry new disposal costs. This shift may alter the total cost of ownership for your customers. Highlighting the long-term disposal savings of non-mature, highly recyclable products can be a powerful sales argument.

Second, use the nine-month notice period to your advantage. When negotiating annual contracts with manufacturers, demand full transparency on their eco-contribution tariffs. Ensure that any potential tariff changes are communicated in alignment with the legal notice period, allowing you to protect your margins.

Finally, invest in yard infrastructure. Since free collection will only continue for sorted non-mature materials, merchants who provide clear, well-managed sorting facilities will attract more trade customers. Helping contractors navigate the end of free take-backs for wood and plaster will build long-term loyalty in a highly competitive market.
