Turning Legacy Fly Ash Into the Infrastructure of Tomorrow

Cinder Residuals recovers, processes, beneficiates, and markets previously stored fly ash for beneficial use in concrete and infrastructure. We transform legacy ash resources into dependable, specification-grade supplementary cementitious materials that improve concrete performance, reduce reliance on portland cement, and support more sustainable construction.

Our work connects two important needs: the responsible reuse of historically disposed material and the growing demand for reliable Class F fly ash. By controlling the process from selective harvesting through final quality assurance, we provide concrete producers with a consistent, commercially scalable source of high-quality fly ash.

A Long-Term, Large-Scale Resource

Through our strategic relationship with Commercial Liability Partners (CLP), Cinder Residuals holds exclusive rights to harvest and market fly ash from significant legacy disposal sites.

Our initial Texas resource positions contain more than 60 million tons of Class F fly ash. These substantial reserves give Cinder Residuals the ability to support ready-mix producers, contractors, infrastructure programs, and other concrete markets for decades.

Our flagship operation in Fairfield, Texas, is strategically located to serve major markets throughout Texas and the surrounding region. As traditional supplies of freshly produced fly ash decline with coal-fired power plant retirements, these recovered resources provide an increasingly important source of supplementary cementitious material.

More Than a Material Supplier

Cinder Residuals manages the entire material lifecycle—from initial resource characterization to customer delivery.

Our integrated capabilities include:

• Resource evaluation and material characterization

• Selective harvesting and controlled excavation

• Strategic blending and feedstock management

• Screening, drying, classification, and milling

• Particle-size and moisture optimization

• Laboratory testing and production quality control

• Bulk storage, loadout, and transportation coordination

This vertically integrated approach gives us greater control over material consistency, plant performance, production capacity, and final product quality.

Consistency Engineered Into Every Ton

Legacy ash deposits can contain variations caused by historical plant operations, placement methods, and storage conditions. Cinder Residuals addresses those differences through detailed resource mapping, selective harvesting, controlled blending, and advanced processing.

Rather than relying on material from a single excavation area, we combine targeted portions of the resource to create a more uniform plant feed. The material is then processed and tested before being placed into finished-product storage.

Our quality assurance program evaluates important characteristics such as:

• Chemical composition

• Loss on ignition

• Moisture content

• Fineness and particle-size distribution

• Strength activity

• Water demand

• Air-entrainment compatibility

• Sulfate and alkali content

This disciplined process is designed to produce consistent fly ash meeting applicable ASTM C618, Department of Transportation, and project-specific requirements. Cinder Residuals’ Texas source has also been accepted for applicable TXDOT concrete applications. Industries Served

Better Material for Better Concrete

Class F fly ash has been used successfully in concrete for decades. Its pozzolanic properties can improve both fresh and hardened concrete performance while reducing the amount of portland cement required in a mix.

Depending on the mix design and project requirements, Class F fly ash can provide:

• Increased long-term strength

• Reduced permeability

• Improved workability

• Lower heat of hydration

• Greater resistance to sulfate attack

• Mitigation of alkali-silica reaction

• Reduced shrinkage

• Improved durability

• Lower embodied carbon

Cinder Residuals combines this proven chemistry with modern recovery, processing, and quality-control systems to deliver a reliable material for today’s concrete market.

Sustainability Through Beneficial Use

Our business is built around practical resource recovery. Every ton of legacy fly ash beneficially used in concrete is a ton of material returned to productive service rather than remaining in long-term disposal.

Using fly ash as a partial replacement for portland cement can also reduce the embodied carbon of concrete because it lowers demand for energy-intensive cement production. This creates measurable value across the construction supply chain while supporting landfill reduction, site closure, resource conservation, and lower-carbon infrastructure.

Cinder Residuals makes sustainability operational by converting an existing material resource into a valuable component of durable concrete. Sustainability

Positioned for Responsible Growth

Cinder Residuals is establishing a scalable platform for recovering and processing legacy fly ash across multiple markets. Our Texas operations are the foundation of that strategy, with future growth focused on additional resource locations, processing facilities, logistics networks, and customer partnerships.

Through our continued relationship with CLP and our investment in processing technology, quality systems, and operating expertise, we are positioned to help address the nation’s growing need for dependable supplementary cementitious materials.

Building a More Reliable Supply of Fly Ash

We work with ready-mix producers, precast manufacturers, contractors, engineers, public agencies, and infrastructure owners seeking a dependable source of high-quality Class F fly ash.
