Proprietary Technologies
and Capabilities
Tephra owns a proprietary Thermo-Chemelectronic Decomposition Reactor capable of separating CCR feedstock into its individual elements and recombining those elements into more reactive forms.
Our Reactor enables Tephra to incorporate all typical forms of CCR in our green cement (including fly ash, bottom ash, gypsum, slag, etc. - or any combination of these materials) which represents a major paradigm shift for high-volume beneficial use of CCR.
Our Reactor also eliminates heavy metal contamination from the CCR so Tephra’s beneficial use process is also safe for humankind and the environment we share!
Our Decomposition Reactor is a high throughput, high efficiency, zero emission, zero waste, zero residual process and is capable of processing up to 10,000 tons of CCR per day per project.
Tephra owns a patented, proven, and government-permitted formulation of green cement called “GreenMix™” which incorporates all typical forms of CCR as a feedstock material.
Treating any typical form of CCR (fly ash, bottom ash, gypsum, or slag (or any combination thereof) with our proprietary Decomposition Reactor enables it to be incorporated into GreenMix at ~65% composite volume as a natural pozzolanic material.
The engineering properties of GreenMix are analogous to traditional high-strength concrete. However, traditional concrete requires the use of Portland Cement which is made in energy-intensive kilns that generate more than half a ton of carbon dioxide for every ton of product and that is why concrete is responsible for generating about 7% of global emissions.
Treating the CCR with our proprietary Reactor totally eliminates the need to incorporate Portland Cement so there are zero emissions associated with the production or use of GreenMix!
The presence of Heavy Metals and Naturally Occurring Radioactive Materials (NORM or TENORM) often prevents safely repurposing CCR in a manner that does not simply propagate the owner’s liability.
In addition to incorporating free water, pore water, and groundwater directly into GreenMix production, Tephra also has proprietary in-vitro, chemical-free, water treatment systems that are capable of remediating all typical forms of CCR contamination including heavy metals such as mercury, arsenic, selenium, lithium, etc. to non-detect levels.
Water treated by Tephra’s water treatment systems will exceed EPA Surface Water Discharge Standards so that it can be discharged under the existing stormwater permit or reused for other beneficial purposes.
