Surschiste

What Surschiste does

SURSCHISTE is a French commercial and industrial operator that enhances, markets, and sells by-products from coal-fired power plants, including silico-aluminous fly ash, bottom ash, fluidized-bed ash, glazed ash and desulfogypsum. Founded in 1959 in Lens (Pas-de-Calais) and now a subsidiary of EPPM (EP Power Minerals) since 2023, the company runs two ash-drying installations (Saint Avold at 80 t/h, Hornaing at 50 t/h) and three UPPC ready-mix compound units (Saint Avold, Provence UPPC 2, Provence UPPC 3 commissioned in 2016) that convert raw by-products into certified construction inputs marketed under registered trademarks (SILICOLINE®, SODELINE®, SILICOLIT®, SODELIT®, SILICOLINE® C, SIB-PI®, SIBACTIV®, GARDANEX®, GARDALITHE®, COMBLEX®, INJEX®, GYPSALINE®). Revenue is generated on a transaction basis from sales of base by-products and processed branded products, augmented by fee-bearing ash-management services for power plant operators (including the EP Produzione plant in Fiume Santo, Sardinia, since 2020), with reported FY2020 turnover of €20 million and a registered share capital of €2,487,510.

The go-to-market is B2B, sales-led, and geographically anchored through three regional agencies (Saint Avold in the East, Hornaing in the North, Meyreuil in the South) plus the Lens HQ. Customers are vertical rather than named accounts: ready-mix and pre-fab concrete producers, cement manufacturers, road and civil engineering contractors, geotechnical specialists, agricultural soil amendment buyers, and environmental remediation firms, all served under French, Belgian (BENOR) and German (DIN) certifications (ISO 9001 since 2003, ISO 14001 since 2011, ISO 45001 since 2020, plus the RSE Engagé CSR label from 2023). SURSCHISTE also acts as the regulated outlet for several coal-plant operators, owning ash landfills at Harnès/Courrières, Vermelles, Hornaing and Sainte Fontaine and co-founding the UFCC industry body with EDF and La SNET in 2004.

Key inflection points include ownership transitions (100% SNET in 1997, E.ON majority via SNET in 2008, Uniper France after the 2015 E.ON split, and EPPM in 2023), the 1989–1990 dryer build-out that aligned the company with rising ash volumes, the launch of branded trademarks beginning in 1999, the successive commissioning of UPPC units in 2000, 2001 and 2016 that drove product mix up the value chain, and the 2020 Sardinia expansion. Over 60 years of continuous operation the company has commercialized more than 65 million tonnes of ash.

Revenue model

1. Sale of Ash By-products: SURSCHISTE generates revenue primarily through the commercial sale of processed by-products from coal power plants. Base products include SILICOLINE® fly ash, SILICOLIT® bottom ash, SODELINE® fluidized bed ash, SODELIT® bottom ash from fluidized bed combustion, glazed ash, and desulfogypsum (industrial calcium sulfate). These are sold as raw materials or as processed products. Revenue is transaction-based, driven by tonnage volumes and product specifications.
2. Processed/Elaborated Products: Ready-to-use products manufactured through UPPC mixing units, sold under trademarked brands. Includes concrete additives (SILICOLINE® C), hydraulic soil treatment binders (SIB-PI®, SIBACTIV®, GARDANEX®, GARDALITHE®), grouting/injection products (COMBLEX®, INJEX®), and gypsum products. Revenue derived from value-added processing, commanding premium pricing over raw ash products. 2020 revenue reported at €20 million.
3. Ash Management Services for Power Plants: SURSCHISTE provides controlled management of by-products for coal power plant operators, including ash from the EP Produzione plant in Fiume Santo, Sardinia (since January 1, 2020). Services encompass ash handling, drying, storage, and logistics coordination, providing a comprehensive waste/by-product management solution to power generators.

Broad incumbents

• EP Power Minerals (EPPM): Parent company of SURSCHISTE since 2023 and the pan-European operator of coal combustion by-product valorization. Operates parallel ash processing operations across multiple European markets (Czech Republic, Slovakia, Bulgaria, Germany), making it both the parent and the most directly comparable broader platform serving similar customers with similar technology.
• Holcim: Global leader in cement, aggregates, and ready-mix concrete with growing focus on supplementary cementitious materials (SCMs) and low-carbon binders. Competes with SURSCHISTE at the customer interface as a vertically integrated buyer/supplier of fly ash and is developing proprietary SCM alternatives that could bypass traditional fly ash sourcing.
• Heidelberg Materials: Major European-headquartered cement and aggregates producer with extensive SCM operations and a strong presence in France. Comparable as a customer and competitor to SURSCHISTE in the cement and concrete value chain, with growing investment in low-clinker binder technologies.
• Cementir Holding: Italian-headquartered international cement producer with operations across Europe and Turkey, active in white cement and specialty binders. Comparable through its Southern European footprint (similar to SURSCHISTE's Provence and Sardinia operations) and its use of fly ash and alternative SCMs in cement formulations.

Direct peers

• Kopf Tonbaustoffe: German-based processor of coal combustion by-products (fly ash, bottom ash) for use in cement, concrete, and road construction. Highly comparable to SURSCHISTE in product portfolio, end markets, and processing technology; serves the German construction market with similar certified SCM and hydraulic binder offerings.
• Vliegasunie: Dutch fly ash processing and trading company supplying the Benelux cement, concrete, and infrastructure markets. Directly comparable to SURSCHISTE in core product (fly ash for concrete) and customer base, though focused on the Netherlands and adjacent Northwest European geographies.
• SEFA Group: French-origin (with US operations) processor and marketer of fly ash and other coal combustion products for the concrete and cement industries. Direct peer to SURSCHISTE in fly ash valorization, with comparable technology and customer overlap in French/European cement markets.
• Charah Solutions: US-based company specializing in fly ash sales, marketing, and CCP (coal combustion products) management for utilities and concrete producers. Highly comparable to SURSCHISTE's core model of CCP valorization and distribution, though focused on the North American market.
• Eco Material Technologies: US-based processor and supplier of fly ash, bottom ash, and synthetic gypsum for cement and concrete applications. Directly comparable in business model (CCP processing and distribution), product portfolio, and end-market positioning to SURSCHISTE, though operating in the North American market.

Others

• UFCC (Union Française des Cendres de Charbon): French coal ash industry association co-founded by SURSCHISTE alongside EDF and SNET in 2004 to defend ash valorization and influence regulatory frameworks. Comparable as an ecosystem/industry body rather than a direct competitor, but materially relevant to SURSCHISTE's market structure, regulatory positioning, and stakeholder relationships.
