# CRH plc > CRH has a materials loop that is visible in products and plants: supplementary cementitious materials, recycled aggregates and road inputs. The first decision is one local material stream and one specification, not a footprint-wide headline. - Industry: Building & Infrastructure - Collection: Active - Regions: North America - Countries: United States - Materials: Cement, Minerals, PFAS, Steel - Processes: Recycling, Energy recovery, Mechanical processing - Evidence through: 2026-09-18 - Canonical URL: https://www.materialtransition.com/library/crh-plc ## Top material flows in Dublin, Ireland (primary listing NYSE) · Packaging, construction & resource materials · Construction & building materials CRH's scale is unambiguous from its own reporting (3,961 locations, 28 countries, North America driving 75% of 2025 net income), but this brief does not establish a current secondary-feedstock purchase specification, contracted buyer or price. Ash Grove publishes product literature, including a Chanute brochure; those documents are not purchase acceptance terms. [7] - Limestone, clay and other mineral feedstock for cement clinker (directional, sector-level) - Aggregates, crushed stone, sand and gravel; CRH's FY2025 filing identifies these as reported material families. [10-K] [6] ### Top waste & residual flows - Directional residual classes: kiln dust, quarry fines, concrete returns, gypsum, mineral wool, process-water solids Qualification remains open: this brief has not established an incoming feedstock acceptance specification or buyer contract for a proposed pilot. ## Who controls the physical system Parent → legal entity → owner → operator → plant, as resolved from public filings. - **Legal entity:** CRH plc (Ireland-incorporated, primary listing NYSE: CRH since 2023 re-domiciliation) - **Global footprint:** 3,961 locations across 28 countries (company-reported, FY2025) - **Regional concentration:** North America generated ~75% of 2025 net income ### Financial scale Scale proxies only, not raw-material purchasing volume unless stated. - **Ticker / CIK:** CRH / SEC CIK 0000849395 (10-K filer) - **FY2025 revenue:** $37.4B, +5% YoY from $35.6B in FY2024 (reported) - **Revenue mix, FY2025:** 32% residential · 28% non-residential · 40% infrastructure - **Aggregates concentration:** CRH estimates that about 95% of total company revenues were connected to aggregates as of December 31, 2025; this is not a North America-only share or a measure of aggregate sales. [FY2025 report] [10] - **2025 M&A:** Acquired North American Aggregates (New Jersey aggregates business), continuing an aggregates roll-up strategy ### Physical system, in plain terms CRH is a vertically integrated building-materials operator: it quarries aggregates (crushed stone, sand, gravel), burns limestone and clay into cement clinker at kiln sites like Ash Grove Cement in Chanute, Kansas, and converts both into ready-mixed concrete, asphalt and paving materials, plus downstream precast, drainage and utility-enclosure products. CRH estimates that about 95% of total company revenues were connected to aggregates as of December 31, 2025; this is not a North America-only share or a measure of aggregate sales. ## Production footprint and plant evidence | Site | Location | Role / evidence | |-|-|-| | North American Aggregates sites (acquired 2025) | New Jersey, U.S. | Acquisition announced 2025, extending CRH's Northeast U.S. aggregates footprint (Reported, trade press). | ### Materials and packaging entering the system | Material / input | Family | Evidence status | |-|-|-| | Limestone and clay | Cementitious mineral feedstock | Directional, standard cement-industry input, not itemized per CRH facility in public filings | | Crushed stone, sand and gravel | Aggregates | CRH estimates that about 95% of total company revenues were connected to aggregates as of December 31, 2025; this is not a measure of aggregate sales. Tonnage per quarry is not public. [FY2025 report] [10] | ### Products and product families | Product / segment | End market | Evidence status | |-|-|-| | Cement (clinker-based) | Construction, infrastructure | Product family identified; Ash Grove links a Duracem F Chanute brochure; current plant output and buyer acceptance are not verified here | | Ready-mixed concrete and asphalt | Residential, non-residential, infrastructure construction | Product family identified; regional mix designs not public | | Precast, drainage and utility-enclosure products | Infrastructure, residential outdoor living | Product family identified per company segment disclosure; SKU-level detail not public | ## Process and conversion Cement production uses limestone and clay in a kiln to make clinker, which is ground with gypsum into cement. The process generates kiln dust and uses fuel, but this brief does not establish plant-specific yields, kiln-dust quantities, or disposition. Aggregate production can generate quarry fines and process-water solids; no plant-level quantities are established here. ### TRI data boundary The cited EPA page is a dataset index. This brief does not reproduce company-specific TRI rows or establish facility matches, chemical quantities, or management pathways. ## Regulatory position - Cement kilns are subject to EPA National Emission Standards for Hazardous Air Pollutants (NESHAP) for Portland cement manufacturing; specific facility-level compliance status is not itemized in this brief. - State and federal beneficial-use rules govern whether kiln dust, fly ash substitutes, or recycled concrete aggregate can be reused as a secondary cementitious material, this is the binding regulatory gate on any recovery pilot. ### Certification and standards signals - No CRH-specific Environmental Product Declaration (EPD) or low-carbon-cement certificate is verified at the facility level in this brief. - Industry-standard frameworks relevant to this sector, ENVIRON EPDs, ASTM C1157 performance cements, and state DOT recycled-aggregate specifications, are directional sector context, not confirmed CRH certifications. ### Innovation, pilots and announced capacity - Acquisition of North American Aggregates (New Jersey, 2025), extending CRH's Northeast U.S. aggregates concentration (Reported, trade press). - Ash Grove describes Durabase using cement kiln dust for soil stabilization, Durapoz F using ground Class F fly ash, and Duracem F using interground Class F fly ash. These are company-reported product pathways, not verified quantities, sourcing contracts or feedstock acceptance guarantees. [7] - CRH's September 2020 disclosure describes a tyre-fuel system at Ash Grove's Midlothian, Texas plant. This is a dated, site-specific company disclosure; it does not establish current operations or a CRH-wide fuel mix. [8] ## Potential offtakers and receiving markets **Evidence register.** The sources and qualification questions in this panel are the public record used for this brief. Company claims, facility matches, directional hypotheses and unresolved questions are kept separate. - Cement and aggregate plants are themselves the natural first-tier receiving class for recycled concrete aggregate and mineral fines, CRH could be both generator and buyer within its own network (Directional, potential class only). - Asphalt and road-material producers are an established secondary destination for concrete and aggregate fines industry-wide (Potential class only, no named CRH buyer relationship is public). - Slag and other secondary minerals are candidate inputs to investigate. No supplier-to-CRH relationship is established by this brief; chemistry, contaminant limits and receiving-site requirements must be checked separately. ### Material transition opportunity #### Qualify one kiln or quarry for a named secondary-mineral input Ash Grove's named products provide a concrete starting point for secondary-mineral research. A proposed input still needs a receiving plant, composition data and acceptance requirements. Neither the imported facility count nor a product brochure proves an available buyer or qualified waste stream. The sources reviewed do not establish a named site's acceptance specification for kiln dust, quarry fines, or another secondary feedstock. 1. **Evidence boundary:** before using any facility-level EPA TRI data, reproduce the specific source rows and independently verify current ownership and operating control. 2. **Not established by the sources reviewed:** This brief has not verified an open feedstock procurement program, buyer contract or plant-level recovery volume. ### Sources - CRH nets $3.8B in 2025 Construction & Demolition Recycling (trade press, citing CRH results) · 2026 · freshness: Current https://www.cdrecycler.com/news/crh-earnings-2025-profits-aggregates-concrete-recycling-usa-europe/ [1] - CRH acquires North American Aggregates Construction & Demolition Recycling · 2025 · freshness: Current https://www.cdrecycler.com/news/crh-ireland-usa-acquisition-naa-aggregates-new-jersey-2025/ [2] - CRH plc, Form 10-K, FY2025 U.S. Securities and Exchange Commission (EDGAR) · Filed 2026 · freshness: Current https://www.sec.gov/Archives/edgar/data/849395/000162828026009043/crh-20251231.htm [3] - CRH plc Wikipedia (background/structure reference only, not a primary source for figures) · Accessed Sep 16, 2026 · freshness: Aging https://en.wikipedia.org/wiki/CRH\_plc [4] - TRI Basic Data Files, Calendar Years 1987---Present U.S. EPA Toxics Release Inventory Program · 2024 reporting year · freshness: Current https://www.epa.gov/toxics-release-inventory-tri-program/tri-basic-data-files-calendar-years-1987-present [5] ## Material Transition editorial interpretation Material Transition interpretation, not a company-reported project: begin with a named receiving site and a secondary-mineral specification.
