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]

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.

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]

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.

Materials and packaging entering the system

Products and product families

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.

• 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]

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.
