From forgotten waste to global supply chains, MTM’s breakthrough technology is rewriting the rules of industrial materials.
It seems we’ve hit an inflection point. The bargain of offshoring has unraveled — paid not in dollars, but in volatility, vulnerability, and vanishing control. Yet bringing key industries back home isn’t as simple as waving a flag. The old methods are too dirty, too slow, and too expensive. But what if there were a way to unlock strategic resources — metals, minerals,
even graphene — from everyday waste, right here at home?
In 2020, I stumbled upon a
Rice Universityarticle detailing a breakthrough in graphene production called flash Joule heating. In essence, FJH sends a sudden, high-voltage electrical pulse through nearly any carbon-based material — trash, coal, even food waste. This instant jolt generates extreme heat, reaching thousands of degrees Celsius in less than a second. The process is so intense and fast that it breaks apart old molecular structures and forces the carbon atoms to rearrange themselves into graphene: a single layer of carbon, stronger than steel, incredibly light, and packed with commercial potential.
The significance wasn’t lost on me. Graphene had long been among the most promising materials of the future, oozing with nearly unbelievable applications, but the tech to produce it cheaply and cleanly never seemed to arrive — until now. Needless to say, my interest was captured and I followed, waiting for developments — or better yet, an investment opportunity.
At long last, in March 2024, researchers at
Rice University reached an agreement with with MTM Critical Metals, granting them the exclusive global license to commercialize the flash Joule heating technology for recovering rare earths and strategic metals. Despite the lackluster news coverage, that was the moment everything changed. MTM now held a golden ticket, all that remained was execution — and boy, have they delivered so far.
MTM didn’t waste time. Soon after securing the license, they began scaling the technology for industrial testing — not just to prove it works in theory, but to make it commercially viable. MTM confirmed and expanded on Rice’s original findings: the flash Joule process didn’t just produce graphene. It could extract a wide range of metals — including rare earth elements and critical minerals — often at
recovery rates that rivaled or exceeded traditional mining. And not from high-grade ore, but from trash. From coal ash. From electronic waste. In other words, materials we literally throw away.
In pilot tests, MTM’s flash Joule heating process
recovered around 90% of gallium and over 80% of germanium from semiconductor waste, two critical metals the U.S. currently imports entirely. Germanium — essential for infrared optics, advanced electronics, and military tech — has zero domestic production, making this breakthrough not just economically valuable but strategically urgent.
The same process
recovered over 95% of gold and titanium from electronic waste. Perhaps even more impressively, it
increased the recovery of rare earth elements from coal fly ash — a waste byproduct of coal combustion — by enhancing acid leachability over 500% compared to conventional methods. This unlocks vast potential to sustainably produce critical materials, crucial for magnets, electric vehicle motors, wind turbines, and advanced electronics, directly from industrial waste previously destined for landfills.
Antimony is another standout. In June 2025, MTM announced a
98% recovery rate for antimony from U.S.-sourced electronic waste using their proprietary FJH technology. Even more impressive, the resulting concentrate contained 3.13% antimony, far above typical global mine grades of just 0.1 to 1.0 percent. This matters because antimony is classified as a critical mineral by the U.S. government, essential for everything from flame retardants and lead-acid batteries to semiconductors and military alloys. With the United States currently almost entirely dependent on Chinese imports, MTM’s approach could mark a turning point.
But it’s not just about efficiency, it’s about economics and sustainability. Flash Joule heating doesn’t require harsh chemicals or furnaces, and produces minimal secondary waste. MTM’s own analysis suggests the process could actually cost less than conventional disposal methods for industrial byproducts. In short: they’ve created a cleaner, cheaper, and strategically superior alternative to both mining and landfilling.
MTM isn’t just talking the talk, they’re making bold moves. Recently, they
secured a strategically positioned five-hectare industrial site in Chambers County, Texas, nestled within America’s Gulf Coast energy corridor. This site provides ideal logistical advantages, offering direct access to key transportation routes including Interstate 10 and the Houston Ship Channel. Moreover, the property already comes equipped with essential infrastructure — sealed roads, on-site power, wastewater systems, and existing office and warehouse spaces — which significantly reduces initial investment and accelerates project timelines.
This isn’t just another industrial plot, it’s MTM’s U.S. flagship.
By the end of 2025, MTM plans to commission its first American Flash Joule Heating demonstration plant on this very site, dedicated to recovering critical metals like gallium, germanium, indium, and gold directly from industrial and electronic waste streams. They’ve already secured feedstock agreements with American recycling partners and are advancing discussions with
industry leaders like Indium Corporation. With this strategic foothold, MTM is not only commercializing a groundbreaking technology — they’re reshaping America’s critical materials landscape, strengthening domestic supply chains, and paving the way for a cleaner, more secure industrial future.
MTM Critical Metals is primarily listed on the Australian Securities Exchange (ASX) under the ticker MTM. For U.S. investors, the company is accessible via the over-the-counter (OTC) market under the ticker MTMCF. It’s important to note that MTMCF is not a separate company; it represents the same underlying entity as MTM on the ASX.
However, MTMCF typically experiences lower trading volumes compared to its ASX counterpart, which can lead to wider bid-ask spreads and potentially less favorable pricing. This discrepancy is due to the OTC market’s nature, which doesn’t have the same liquidity as major exchanges.
Holding MTMCF is functionally equivalent to holding the underlying ASX stock, just via a U.S. OTC “wrapper.” If MTM up-lists to a U.S. exchange, the OTC shares (MTMCF) would typically be converted or exchanged for the new U.S.-listed shares on a 1:1 basis. Should MTM pursue an exchange upgrade, it could significantly enhance liquidity, potentially leading to increased institutional interest and a broader shareholder base.
As of June 6, 2025,
MTM’s share price on the ASX stands at AUD $0.495, reflecting a remarkable 1,119.51% increase over the past 52 weeks. This surge underscores growing investor confidence in the company’s innovative Flash Joule Heating (FJH) technology and strategic initiatives. The company’s market capitalization has reached approximately AUD $229 million, positioning it as a significant player in the critical metals sector. Notably, MTM has no debt and maintains a strong cash position, providing a solid foundation for its ongoing projects and potential expansion.
Yet even after this meteoric run, MTM remains a true small-cap — roughly USD $170 million at current exchange rates — leaving immense upside on the table if the company executes. With its Texas plant set to begin operations by year’s end, MTM is moving from pure promise to revenue reality. The company’s ability to scale Flash Joule Heating at an industrial level could rapidly unlock new revenue streams and validate the business model, attracting fresh capital and potentially even institutional coverage. If the technology delivers as expected and MTM manages an exchange upgrade, the re-rating could be dramatic. For now, MTM sits in that rare sweet spot: a category-defining innovation at a valuation that still reflects skepticism, not success. If they deliver, today’s price will look like a rounding error.
The implications here are hard to overstate. This isn’t just a new mining technique, it’s a technology that can transform trash and industrial byproducts into the very metals driving the future economy. In a world desperate for secure, ethical, and scalable supplies of critical materials, MTM’s breakthrough doesn’t just disrupt, it redefines the entire resource landscape. This is the kind of inflection point investors spend careers searching for: the moment when science fiction becomes industrial fact, and fortunes are built by those willing to see it early. And right now, the window is still wide open.
But even that isn’t the whole story. The graphene angle is the wild card almost nobody sees coming. For over a decade, investors have been waiting for the “graphene revolution” and the breakthrough that finally makes large-scale, low-cost production real. MTM’s process has the potential to do exactly that, turning everyday waste into one of the most valuable materials on earth. The use cases — next-gen batteries, aerospace composites, water purification, flexible electronics — are staggering, and trillion-dollar markets could open up overnight. Yet the market remains almost entirely blind to this. If MTM captures even a fraction of this potential, the upside could be orders of magnitude greater than what’s being projected from metals recovery alone.
That’s why this isn’t just another promising tech stock, it’s a generational opportunity. MTM sits at the intersection of two seismic shifts: critical metals independence and the long-awaited graphene breakthrough, both powered by a technology that literally turns trash into treasure. In a market crowded with noise and empty promises, this is a rare shot at being early to something real. These are the kinds of moments that turn bold conviction into legacy.
