Revenue model

1. Mineral product sales: Sale of processed mineral products — calcium carbonates (limestone aggregates, sands, fillers, micronised carbonates), quicklime, slaked/hydrated lime, and basic mineral soil improvement products — to B2B customers across agriculture, building & public works, animal feed, environment, and industrial sectors. Products sold in bulk, bags, big bags, or as-spread; revenue is transactional per delivery/contract.
2. Freight transport and logistics services: Subsidiary Les Transports de Saint Hilaire provides dedicated freight transport using the group's own vehicle fleet. Services include bulk tanker delivery, bagged/big-bag delivery, right-to-the-root spreading, and on-site spreading with 4x4 spreading units. Revenue generated through transport and service contracts.
3. Custom formulation and technical services: Technical support, formulation studies, analysis services, and custom mineral mixture preparation using crusher-dryers. Engineering and design office services for customers' site-specific applications. Revenue through project-based service engagements.

Core offering

Saint Hilaire Group extracts high-purity oolithic limestone from the La Gagne quarry near Trept, France, and processes it through crushing, drying, classification, calcination, and micronising to produce calcium carbonates (limestone fillers, aggregates, sands), quicklime and slaked lime, agricultural soil amendments, GMP+FSA-certified animal feed carbonates, and specialty formulated mineral products (POROCAL, PORODOL, FILAFLUID, OPTIVIVE, HYGIACAL, Sulfocho). The group also operates its own transport fleet and provides on-site spreading, quality control, and technical support services.

Product overview

Saint Hilaire Group is a family-owned mineral producer operating since 1947, extracting limestone from quarries near Lyon, France, and processing it into a comprehensive portfolio of mineral products. The core offerings include calcium carbonates (Limestones and Carbonates, POROCAL®, FILAFLUID®), lime products (Quicklime and Slaked Lime, OPTIVIVE®, HYGIACAL®, ST HILAIRE®), aggregates and sands (Saint Hilaire® range), agricultural soil improvements (OPTICAL®, OPTIDOL®, OPTIVIVE®, OPTIMIX®), animal feed carbonates, and specialty formulated products (hydraulic binders, calcium sulphate, PORODOL®, Sulfocho®). The company also provides integrated services including quality control, transport, logistics, spreading, storage, and technical support. Products serve five main sectors: building and public works, agriculture, animal feed, environment, and industrial applications (chemical, metallurgical, paper, glass, food processing).

• APATAM (Association pour l'Accompagnement et la Promotion des Actions au Togo, Au Mali et au Sénégal)minorOthers · 14 February 2024Saint Hilaire Group partnered with APATAM to support the N'Guelack village in Senegal by contributing to the acquisition of solar pumps. The village, a Peulh community recognised for its self-sufficiency model in agriculture, livestock, and crafts, is being developed as a sustainable living example. The project aims to discourage youth emigration by providing local employment and education opportunities.
• ECTP - Eric ComteminorStrategic or Co-development PartnerECTP, a small public works company (8 employees, 3 trucks, 7 excavators) based near Saint Hilaire's operations, has collaborated with the group since 2001. For the Via Rhôna cycling path project, ECTP used Saint Hilaire stabilised aggregate (stabilisé Saint Hilaire®) for both the adjustment and finishing layers. The collaboration enables Saint Hilaire to showcase its materials in regional infrastructure projects.
• UNIFA (Union des Industries de la Fertilisation)coreOthersSaint Hilaire participates in UNIFA, the professional organisation representing plant nutrition industries in France. Luc Chorier, head of the Agricultural Department, was elected President of the Basic Mineral Amendments section in March 2023 for a 3-year term. The group contributes to the section's roadmap on agronomic index development, carbon footprint studies, soil pH mapping, and regulatory monitoring.
