As coal plant retirements continue to reduce the availability of current-production fly ash, harvesting of previously disposed ash becomes increasingly important to ensure a ready supply of pozzolanic material for use in the production of concrete. For several years, Eco Material has been harvesting and beneficiating fly ash from a monofill in central Pennsylvania for sale into regional concrete markets. Additionally, we have harvesting projects underway in Georgia and Texas that will allow for the harvesting and beneficiation of fly ash and bottom ash and their sale, as well as that of blended ash, into these concrete markets.
In such instances, Eco Material Technologies can perform testing, reclamation, and marketing of coal ash to ensure it meets all regulatory and commercial requirements. Material characterization studies of reclaimed ash to evaluate its potential for beneficial use. Characterization involves developing a material sampling plan, sample collection, physical testing, chemical analysis, and interpretation of results.
Testing is performed at the company’s material testing and research facilities, whose capabilities include microscopy, particle size analysis, carbon content, magnetic content, X-ray fluorescence, atomic absorption, various wet chemistry analyses, as well as conventional construction material testing. Analysis of test results allows Eco Material to determine CCPs’ physical, chemical, and mineralogical characteristics; the presence of any potential contaminants; and ultimately their pozzolan performance attributes.
Based on the conclusions of this analysis, Eco Material can advise customers as to the suitability of the reclaimed ash for various end uses, including concrete and other durable applications.
Eco Material can also recover and process landfilled materials to reclaim pozzolanic value. We will partner with utilities who subsidize capital to promote the restoration and beneficiation of these sites.
