Beneficial Reuse of CCR to Manufacture LEED Construction Material without Creating Another Waste Stream
Randall Stremmel – Brixx Technology
This abstract discusses the research and development undertaken by Brixx Technology to utilize coal combustion residuals (CCR) in manufacturing sustainable building materials. The study aimed to determine the feasibility of producing eco-friendlier alternatives to existing reuse programs. The process involved a systematic approach to meet ASTM specifications for commercial building materials while ensuring economic viability. Initial experiments were conducted on a pilot scale, validating the feasibility of producing high-quality products using off-spec, F-class, and landfilled ash. The process involves combining fly and bottom ash with proprietary binders, water is added, and the mixture is pressed into desired shapes, followed by hydrothermal curing to form durable building materials. Mechanical properties were validated through internal and accredited laboratory testing. A mass production facility was established in India, demonstrating consistent quality and financial feasibility, followed by a facility in the United States in Ohio. Environmental benefits include reduced energy consumption, shorter production times, and elimination of waste streams. Alternative uses of CCR, combined with other industrial waste, were explored successfully. Future directions involve sequestering CO2 in the manufactured products. The study showcases the potential of CCR-based building materials for sustainable construction practices.

Setting the Stage: Proposed Legacy CCR Surface Impoundment Rule
Setting the Stage: Proposed Legacy CCR Surface Impoundment Rule
Mark Rokoff – Burns & McDonnell
On May 18, 2023, the EPA published their proposed Legacy CCR Surface Impoundment Rule which has created quite a stir in the scope and breadth of what is intended to be required (and the corresponding schedule to execute). There is a lot to understand and subsequently begin planning for based on the proposed requirements throughout the fleet. Mark Rokoff will present a deeper dive into new rule to aid in understanding and implementation. The presentation will focus on the following:
- Stage setting: Review a modern history of the CCR Rule and discuss why and how we got here
- Overview of the Rule: A high-level overview of the content of the rule and key issues
- Detailed Summary: An intentional presentation of the rule, what is included, how it applies, what needs to be done and the proposed timing (with a bit of commentary)
- Preparation: A conversation of next steps to prepare for implantation and a discussion of what may come. Intended to be a comprehensive conversation on the new legacy CCR Rule and address how to prepare.

Beneficiation of Harvested Fly Ash Using a Triboelectric Belt Separator
Beneficiation of Harvested Fly Ash Using a Triboelectric Belt Separator
Steve Sullivan – Separation Technologies
Tribo-electrostatic separation has been used for the commercial beneficiation of coal combustion fly ash to produce a low carbon product for use as a cement replacement in concrete for twenty-five years. With 24 separators in 18 coal-fired power plants and cement plants across the world, Separation Technologies’ (ST) patented electrostatic separator has been used to produce over 20 Million tons of low carbon product that has been recycled for use in concrete or cement production. To date, commercial tribo-electrostatic beneficiation of fly ash has been performed primarily on dry “fresh” or “production” ash. Reductions in the quantity of dry fly ash generated and requirements to empty historical ash landfills and ponds has created the need to develop a process to reclaim and beneficiate landfilled or ponded ash.
ST has developed and commercialized a new process for beneficiation of reclaimed fly ash from landfills and ponds that utilizes fly ash drying and deagglomeration technology together with the ST tribo-electrostatic carbon separation technology. ST has installed a demonstration of this new process at the Talen Energy Brunner Island power station near York PA. The ST fly ash beneficiation process offers both utility and cementitious materials customers an environmentally friendly, low-carbon emission, fly ash recycling technology which enables cost effective landfill and pond reclamation.

Cost-Effective, Green, Concrete Domes for Bulk Storage of CCPs
H3.3 Cost-effective, Green, Concrete Domes for Bulk Storage of CCPs
Ted Parkinson, Business Development Director – Domtec International, LLC
This paper focuses on optimizing bulk storage of Coal Combustion Products (CCPs). It discusses state-of-the-art, green (climate friendly), storage structure solutions for plants, terminals and ports using concrete domes in both domestic (USA) and overseas markets.
Various successful storage projects will be discussed including for fly ash, limestone, coal, and FGD gypsum. The benefits of dome storage will be addressed as well as various methods for product handling and reclaim, including automated reclaim systems mechanical and pneumatic (screws, stacker-reclaimers, and fluidized floors, etc.).
The paper will also demonstrate how concrete domes are truly a ‘green’ storage structure alternative.
3 short Questions
- How are concrete domes a more efficient type of storage structure?
- In what ways are concrete domes considered ‘green’?
- What is a concrete dome’s productive life span?
