Solvay

What Solvay does

Solvay S.A. is a publicly listed Belgian essential and specialty chemicals company (Euronext Brussels and Paris: SOLB), founded in 1863 and headquartered in Brussels. Following the December 2023 spin-off of its specialty materials business into Syensqo, the post-spin Solvay operates 43 production sites across 41 countries, employs ~8,400–9,000 people, and generated FY2025 underlying net sales of €4.3 billion. The portfolio is organized into two segments: Basic Chemicals (soda ash and derivatives, peroxides) and Performance Chemicals (high-performance silica, Coatis, Special Chem), serving seven primary end-markets — automotive, building & construction, consumer goods & healthcare, electronics, food & feed, industrial applications, and resources/environment/energy.

Core products span commodity intermediates (SODA SOLVAY®, BICAR®, INTEROX®, hydrogen peroxide), high-purity specialty chemistries (Zeosil® highly dispersible silica for tires, Solvaclean® zero-GWP F2 gas for semiconductor CVD chamber cleaning, INTEROX® Pico/PicoPlus for wet etching, Zenus® CMP slurries, LiTFSI/LiFSI conductive salts for EV batteries, EURECO® PAP bleach activator), branded performance materials (Nocolok® brazing, Alve-One® foaming, Eolys PowerFlex®, Actalys®/Optalys® emission catalysts, SOLVAir® flue gas treatment, Rhodianyl®/Rhodiacid® polyamides), and strategic materials (rare earth oxides from La Rochelle, France). The technology backbone rests on proprietary process innovation including the e.Solvay next-generation soda ash process (piloting, targeting 50% CO2 reduction), HPPO propylene oxide, bio-circular silica from rice husk ash, and the upheld EP 3 971 138 B1 soda ash recycling patent.

Solvay monetizes through volume-based industrial sales contracts (multi-year enterprise supply agreements) on Basic Chemicals and differentiated, application-engineered formulations on Performance Chemicals, with pricing negotiated by product/volume rather than publicly disclosed. Distribution is via a direct enterprise sales force (country-level headquarters and account teams across 41 countries), e-Business webshops, and OEM co-development partnerships (e.g., Bridgestone for TECHSYN tire compounds). Embedded services such as automated SDS distribution in 39 languages support compliance-led stickiness with B2B customers.

Product overview

Solvay is a specialty and essential chemistry company organized into two business segments — Basic Chemicals (Soda Ash & Derivatives and Peroxides) and Performance Chemicals (Silica, Coatis, Special Chem) — plus a regional Latin America business. Its portfolio is a unified set of chemical categories (soda ash, sodium bicarbonate, peroxides, high-performance silica, fluorine chemicals, rare earths and metal oxides, oxygenated solvents, phenol/polyamides/intermediates) that Solvay sells both as raw materials and as branded finished products under names such as Zeosil®, INTEROX®, Solvaclean®, Augeo®, Nocolok®, Alve-One®, Eolys PowerFlex®, SOLVAir®, Rhodianyl®, Tixosil®, and Zenus®. Named product platforms cross-cut the segments: e.Solvay is the next-generation soda ash process, TECHSYN is the tire compound co-developed with Bridgestone, and the circular Highly Dispersible Silica from rice husk ash links the Silica business to the company's sustainability roadmap. The chemical categories supply end-markets (Automotive, Building & Construction, Consumer Goods & Healthcare, Electronics, Food & Feed, Industrial applications, Resources/Environment/Energy) that Solvay serves through both its bulk basic chemicals and its specialty brands.
