The end of halogenated flame retardants: Europe's regulatory shift

Wave 1, REACH and the gradual ban on halogenated chemistry

The European REACH regulation has, for years, been progressively restricting brominated and chlorinated flame retardants. Compounds long used in electronics, textiles, and construction insulation have either been banned outright or placed on the candidate list for authorization. Decabromodiphenyl ether (decaBDE), HBCDD, and several PFAS-related compounds have already left the market. Others are scheduled for phase-out.

For materials manufacturers, this creates a recurring compliance problem: every few years, another halogenated additive becomes restricted, forcing reformulation of entire product lines. The cost is real, the engineering effort substantial, and the regulatory horizon perpetually uncertain. Switching to a fundamentally non-halogenated solution removes the entire risk class.

Wave 2, the EU Green Deal and circular materials

The Green Deal goes further than chemical restrictions. It pushes the construction and industrial sectors toward materials that are recyclable, low-emission, and safe across their full life cycle, from production to end-of-life. Halogenated flame retardants are difficult to recycle because they release toxic compounds when waste materials are processed or incinerated. This makes them increasingly incompatible with the circular economy direction European institutions are codifying.

Mineral-based, halogen-free solutions sit on the right side of this shift. They can be incorporated into materials that downstream actors will be able to recycle, reuse, or dispose of without producing hazardous emissions. For specifiers and architects targeting Green Deal alignment or sustainability certifications such as BREEAM and HQE, the choice of fire-protection chemistry now matters more than it ever has.

Wave 3, post-Grenfell building codes

The 2017 Grenfell Tower fire in London marked a turning point in how European authorities approach building fire safety. The investigation exposed how facade and insulation systems tested in laboratory conditions could fail catastrophically in real fires, particularly when smoke toxicity was not adequately measured. In response, building codes across Europe have tightened requirements on:

• Reaction-to-fire classification, pushing more applications toward A1 and A2 (non-combustible) ratings, particularly for high-rise facade systems.
• Smoke production and toxicity, demanding low smoke (s1) and zero burning droplets (d0) classifications for an expanding range of building components.
• Renovation of existing buildings, extending fire-performance requirements to the renovation segment, where retrofit-friendly solutions are essential.

The renovation segment is particularly significant. In Europe, renovation of existing buildings is estimated at €150 billion per year and growing. Most of this stock predates current fire codes, meaning materials that can be applied as a coating or paint to existing surfaces, without structural modification, are uniquely positioned for this market.

The market response

What began as scattered regulatory pressure is now a structural redirection. Specification lists from major European construction groups, public-procurement criteria, and corporate ESG policies all increasingly demand halogen-free fire protection. The market is moving, and it is moving toward solutions that are non-toxic by design rather than by gradual reformulation.

For Neolido and the ANAXA® molecule, this regulatory environment is not a headwind but the underlying driver of demand. The technology was designed for the world the regulations are now creating: one in which fire protection must be high-performance, ecological, recyclable, and applicable across both new construction and existing infrastructure.

The question is no longer whether the market will move away from halogenated chemistries. The question is which solutions will fill the gap, and which of them will be economically and industrially scalable.
