Emerging Technologies

ME2C Environmental is applying our proven expertise in chemisorption, or sorbent technologies, to develop solutions addressing critical areas of environmental concern for the energy sector.

Rare Earth Elements Extraction & Processing

ME2C Environmental are in the process of developing a sorbent technology that will significantly improve the processing of extracted rare earth elements (REEs) from a variety of sources, including mining and coal ash.

Processing rare earth elements from the ore is currently outsourced to other countries, including China, one of the largest providers of REEs globally. Our technology will allow REEs to be processed domestically in a highly cost-effective, environmentally safe manner thus ensuring a more secure U.S. infrastructure.


Coal Ash Pond & Wastewater Remediation

We believe that contaminated coal ash ponds is the most important environmental crisis facing the U.S. energy sector currently. According to a recent report by Earth Justice, there are more than 1,100 coal ash ponds in more than 37 states. Duke Energy’s coal ash pond cleanup was the largest and most costly cleanup to date.

Coal ash is also a rich source of rare earth elements.

Contaminants from coal ash leach into the soil and water streams, referred to as “wastewater” at coal-fired utilities.

ME2C Environmental is developing a new technology focused based on chemisorption focused on acid leaching as a capture method. Acid leaching is widely used to extract rare earth elements. ME2C’s new technology will be introduced into the leaching process and will significantly reduce the amount of caustic acid required. This new technology will also capture contaminants and other minerals from coal ash ponds and wastewater.

More information describing our new technology for rare earths will be available as laboratory testing is completed. We are working to move toward in-field testing late 2021.


Methane Gas – What Is It & Why Are We Concerned About It?

Why are we concerned about it? If methane leaks into the air before being used — from a leaky pipe, for instance — it absorbs the sun's heat, warming the atmosphere. For this reason, it's considered a greenhouse gas, like carbon dioxide. Because methane is so potent, and because we have solutions that reduce emissions, addressing methane is the fastest, most effective way to slow the rate of warming now.

Methane is classified as a "Short-lived climate pollutant", which the Climate and Clean Air Coalition (CCAC) defines as having “global warming potentials many times that of carbon dioxide” and that they “significantly impact food, water and economic security for large populations throughout the world, both directly through their negative effects on public health, agriculture and ecosystems, and indirectly through their impact on the climate.”

The U.S. Energy Information Agency (EIA) states that methane has 86 times the global warming potential of CO2 in the first 20 years after it is emitted. It is crucial to reduce emissions of methane now because of its potentially critical impact on the climate over the next 10 to 20 years. While natural gas can be a bridge to a very low carbon future, managing methane gas emissions in the meantime is crucial.

A paper published in Science Magazine, the American Association for the Advancement of Science, estimates that 7.1 million metric tons of methane emissions arise from leaks and improper venting. This is the area of concern that we at ME2C are addressing. This volume of methane is equivalent to the climate impacts of 160 coal-fired power plants.
