| Headwaters Resources develops and commercializes technologies to improve the quality of fly ash. Simple, economical and highly effective, these technologies help electric utilities continue producing marketable coal combustion products. | |
 |
Carbon Fixation. Under certain conditions, unburned carbon in fly ash can interfere with concrete’s ability to reliably entrain correct amounts of air. Concrete producers are reluctant to use fly ash under these conditions because of the variability unburned carbon can create. |

Ammonia Removal. Ammonia is an emerging challenge in the ash marketing industry. As electric utilities move to implement stringent new air pollution controls, many are treating boiler exhaust gases with ammonia to remove nitrous oxides. Some of the unreacted ammonia is deposited on fly ash particles. When ammonia contaminated fly ash is wetted as part of a concrete mixture, the gas is released, exposing concrete workers to varying levels of ammonia. Headwaters Resources’ new technology uses a chemical reagent to mitigate ammonia effects. When water is added to the concrete mix containing ammoniated fly ash, the reagent converts ammonia to harmless compounds. The treatment reagent can be added and blended with the dry fly ash at any point between the fly ash collection system at the power plant and final delivery to the ready mixed concrete producer. |

Labs. Headwaters Resources utilizes many of the nation’s leading laboratories to support its operational and research activities. Headwaters routinely supports some of the nation’s top university programs engaged in coal ash research and utilizes an array of outside laboratories when independent testing is warranted. Additionally, Headwaters maintains its own state-of-the-art materials testing research facility to support quality assurance and quality control functions, as well as conduct product and technology development activities. |
