Coal-fired power plants and blast furnaces — the traditional sources of fly ash and slag used to cut clinker content — are closing across the EU. India isn't. GeneCapsule connects EU cement producers to vetted Indian supplementary cementitious material supply.
We work both ends of the same supply chain — pick the one that matches you, and the rest of this page (and our follow-up) will speak to your situation specifically.
You're a cement producer, concrete manufacturer, or infrastructure firm looking to diversify supplementary cementitious material sourcing as EU fly ash and slag supply tightens.
Get sourced to India →You're an Indian producer or aggregator of SCMs looking to reach EU buyers, but need help navigating EN 197 series standards, EPD requirements, and export logistics.
Explore EU market entry →Blending clinker with supplementary cementitious materials is one of the fastest, cheapest levers cement producers have to cut emissions. But the two workhorse materials — coal fly ash and blast furnace slag — are both tied to industries actively winding down in Europe.
As EU coal power plants close over the next 10–15 years, their fly ash output — a primary clinker substitute today — declines toward zero.

Source: EEB, "Cement It Better," Jul 2026Each supplementary cementitious material displaces clinker differently, at different maturity levels. Here's where India's supply strengths line up with what EU producers already use or are approved to use.
The most established SCM globally. EU supply is tied to coal power and is structurally declining; India's coal fleet still generates it at scale, with mature collection and quality-grading infrastructure already in place.
India: high availabilityA by-product of blast-furnace steelmaking. As EU steelmakers shift toward direct-reduced iron and electric arc furnaces, conventional GBFS volumes fall. India's blast-furnace steel capacity remains a live source.
India: growing supplyBlended with limestone and clinker (the LC3 recipe: ~50% clinker, 30% calcined clay, 15% limestone, 5% gypsum). Needs high-kaolin clay — a resource India has in significant, largely untapped volume.
India: high-kaolin reservesRecovered from crushed construction and demolition waste. Approved under the EU's EN 197-6 standard, but recovery infrastructure is still limited — a documentation and quality-grading capability we can help build with EPD support.
Best sourced locally in-EUWidely permitted under EN 197-1 already. Volcanic pozzolans and limestone fillers are geology-dependent — availability varies by region, and India has workable reserves in several states.
India: regional reservesUses an alkaline medium instead of Portland clinker chemistry entirely. Still awaiting harmonised EU standards (expected via CEN/TC 51), but a longer-term angle worth tracking alongside near-term SCM sourcing.
Emerging — standards pendingAdjust the sliders to model an indicative clinker substitution scenario. This is a planning-level estimate, not an engineering specification.
Illustrative only. CO₂e avoided is estimated at ~0.925 t CO₂ per tonne of clinker displaced, based on published cement industry emission factors. Assumes near 1:1 substitution by mass; actual ratios depend on SCM reactivity, blend design, and applicable standards (EN 197 series). Not a substitute for a plant-specific feasibility study.
India doesn't need to build new supply — it needs a channel to export what it already produces in surplus.
Fly ash generated in India, FY2024–25 — one of the largest volumes of any country.
Share of that fly ash already utilised domestically — proof of mature handling, quality control, and logistics infrastructure.
Share of India's utilised fly ash already going into its own cement industry — a supply chain that's built and running.
High-kaolin calcined clay and granulated slag, both suited to LC3-type and blended cement systems, are also widely available.
