Savannah River National Laboratory pursues porous 'engineered cellular magmatics' from waste glass and ash
Loading...
Summary
Presenters described SRNL’s work to convert post-consumer glass and combustion ash into engineered cellular magmatics (ECMs)—tailorable porous ceramics intended for filtration, remediation and commercial products—and outlined feedstocks, pilot-scale progress and commercialization aims.
Savannah River National Laboratory is developing engineered cellular magmatics (ECMs), porous ceramic materials made by upcycling waste glass and combustion ash for uses including water filtration and environmental remediation, presenters said. "Savannah River National Laboratory has spent decades researching legacy nuclear waste glass and ceramic science," the Presenter said, placing the new work in the lab’s materials-history context.
SRNL described ECMs as geomimetic, porous ceramics whose process and composition can be tailored to yield specific chemical and structural properties. "ECMs are porous ceramic materials...process and composition can be tailored to produce unique chemical and structural properties suited to advanced commercial applications," the Presenter said. The lab highlighted lower processing temperatures than traditional glass recycling and tunable porosity as technical advantages.
A Researcher emphasized potential applications and recent laboratory results, saying the team can "open up cells or close cells as needed," which allows ECMs to be optimized for distinct functions such as water filtration, agricultural substrates and biointerfaces. The Researcher described work growing biofilms on ECMs to remediate hydrocarbons and said SRNL is testing ECMs for nuclear-waste remediation and wastewater filtration. The Researcher also said one investigator has examined blending activated carbon into ECMs to remove forever chemicals (PFAS) from wastewater.
On feedstocks, the lab presented a broad slate: post-consumer waste glass, industrial waste glass, coal ash, mine tailings and residues recovered by landfill mining. The Presenter said the lab is also working with industry partners to valorize ash left from municipal solid-waste combustion (WTE) rather than landfilling it. Citing external analysis, the Presenter added, "An Accenture analysis estimated that $1,000,000,000,000 of untapped resources are sequestered in landfills globally each year." The Researcher argued this shift in thinking is needed because, in the U.S., "about 85% of the glass that we recycle … ends its life in a landfill."
Presenters framed the effort as applied research moving toward commercialization: SRNL aims to establish ECM science as a niche research area and to partner with industry to create products within a circular economic model. The Researcher said the lab has moved technologies from bench to commercial pilot-scale testing in roughly five years, highlighting the program’s focus on practical demonstration and industrial partnership.
The presentation raised several technical and verification items that remain unresolved in the record: specific performance metrics for ECM filtration of PFAS, the composition and pre-treatment required for WTE ash to serve as a reliable feedstock, and independent lifecycle analyses of greenhouse-gas impacts for WTE-to-ECM pathways. Presenters framed those matters as active research tasks rather than completed outcomes.
SRNL’s next steps described in the record are continued feedstock testing, pilot-scale demonstrations with industry partners and commercialization planning within a circular-economy framework. There were no formal votes or policy actions recorded in the transcript.
