Coal ash, red mud, and mine tailings are typically viewed as environmental liabilities. But locked inside these massive waste streams are valuable silica, rare earth elements, and other critical minerals. A Worcester Polytechnic Institute (WPI)-led research team has received a $3.3 million award from the National Science Foundation’s Growing Convergence Research program to explore whether lessons from diatoms, sea sponges, and plants could help recover those resources using less energy and fewer harsh chemicals.

The five-year, two-phase project is led by Mingjiang Tao, associate professor in the WPI Department of Civil, Environmental, and Architectural Engineering, with Professors Carrick Eggleston and Yan Wang serving as co-principal investigators. Researchers from George Mason University, the University of California San Diego, the University of Massachusetts Amherst, and the University at Buffalo will also be involved.

“Recovering critical minerals is only part of the opportunity,” Tao said. “We want to develop a process that uses as much of each waste stream as possible, separating strategically important elements while converting the remaining material into useful products. That whole-material approach could fundamentally change how industries manage waste and obtain essential resources.”

The research addresses two interconnected challenges. Producing many silicon-derived materials used in concrete, glass, ceramics, semiconductors, and silicones can require high temperatures, substantial energy, and intensive chemical processing. At the same time, industries generate enormous quantities of silicon-rich waste, including coal ash residue, red mud, mine tailings, concrete debris, waste glass, and metallurgical slag. Much of this waste is stored in landfills, ponds, impoundments, and large waste piles, even though it contains valuable silicon, critical minerals, and rare earth elements (REE). For example, the estimated 11 million tons of REEs trapped in U.S. coal ash landfills is worth $8.4 billion—nearly eight times the nation’s current raw domestic reserves. These materials are essential for electronics, clean-energy technologies, transportation, and national security.

The researchers will look to nature for possible solutions. Diatoms, sea sponges, and certain plants use biological molecules and organic scaffolds to capture dissolved forms of silicon and assemble them into intricate silica structures under relatively mild conditions. By adapting these mechanisms, the team aims to develop lower-energy methods that break down the silica-rich components of industrial waste, convert the silica into useful materials, and free rare earth elements and other critical minerals trapped within the substances.

The project brings together expertise in biology, geochemistry, materials science, metallurgy, engineering, computational chemistry, and artificial intelligence. Researchers will use advanced computational modeling and artificial intelligence to design specialized biomolecules, predict how those molecules will interact with silicon-rich waste, and accelerate the identification of promising pathways for mineral recovery and materials manufacturing.

As lead principal investigator, Tao will oversee the project’s management and coordination while leading research on biosilicification, the process through which organisms form silica materials, and bio-enabled metallurgy for recovering rare earth elements from silicon-rich wastes.

Eggleston, a professor in the Department of Civil, Environmental, and Architectural Engineering with expertise in geochemistry, will lead efforts to identify, understand, and optimize the chemical reactions involved in breaking down and rebuilding silicate materials. His work will examine the pathways and reaction rates associated with silicate dissolution, repolymerization, carbonation, glass formation, and silicone synthesis.

Wang, the William B. Smith Professor of Mechanical and Materials Engineering and a widely recognized pioneer in battery recycling and sustainable manufacturing, will lead the development of bioengineered processes for recovering rare earth elements and other critical minerals.

The team will also evaluate the economic and practical feasibility of scaling the technologies for industrial applications. If successful, the research could create new pathways for transforming large volumes of industrial waste into marketable products, reducing reliance on newly mined resources, lowering the environmental footprint of materials production, and strengthening domestic supplies of critical minerals and rare earth elements.

WPI graduate and undergraduate students will be involved in the multiyear project as part of the university’s immersive STEM experience. The interdisciplinary research sits at the intersection of sustainability, biotechnology, materials science, data science, and artificial intelligence. This project also aims to cultivate a broader bioengineered, silicon-based materials ecosystem by connecting researchers, industry partners, policymakers, educators, and future innovators across disciplines and sectors.

Trump EPA Accused of Endangering Public as Study Highlights ‘Hidden Health Costs’ of Data Centers

The Environmental Protection Network listed actions “that could increase pollution-related health risks, weaken protections that would otherwise reduce those risks, or shift more costs onto families and communities.”

As President Donald Trump claims that US communities fighting against artificial intelligence data centers are promoting “poverty, crime, and squalor,” a Thursday report details how his administration “is weakening or proposing to weaken pollution and permitting safeguards” for such facilities, to the detriment of public health.

The Environmental Protection Agency’s “mission is to protect human health and the environment,” notes the new report. “Yet Administrator Lee Zeldin has made turning the United States into the ‘AI capital of the world’ a pillar of EPA’s work.”

“The Hidden Health Costs of AI Data Centers”—from the Environmental Protection Network (EPN), which is made up of hundreds of former EPA staffers—documents “at least 30 federal actions since January 2025 that could increase pollution-related health risks, weaken protections that would otherwise reduce those risks, or shift more costs onto families and communities.”

As the document details: “17 of the 30 explicitly cite or target AI or data centers in the action itself or in an agency statement specifically describing or justifying that action. The remaining 13 affect how data centers are powered, what pollution safeguards apply, how projects are approved, or how federal requirements are enforced.”

The report points to the EPA policy that “made it easier for some long-idled facilities to restart without triggering the major air-permitting requirements,” as well as its proposed elimination of federal carbon pollution standards for fossil-fueled power plants and some outstanding state clean-air requirements for areas that failed to meet ozone standards.

The publication also notes the EPA’s extended deadlines for several coal-plant wastewater requirements, newly regulated coal-ash units, the 2024 oil and gas standards, and for states to submit plans to reduce visibility-impairing pollution. The agency further interpreted a policy on nonemergency backup generator use that it framed as a move supporting AI and data centers.

It’s not just the EPA. The US Department of Energy “authorized grid use of backup generation at data centers and other major facilities during emergencies,” the report explains, while the Army Corps of Engineers “expressly named data centers as examples of commercial development covered by” a streamlined water permit.



“No study has yet calculated the combined health effects of these actions, but the direction is clear,” the report says. It cites a study from this year that estimates air pollution related to data centers “could impose roughly $11.7 billion to $20.9 billion in annual public health costs by 2028,” and “contribute to roughly 600,000 asthma symptom cases and 1,300 premature deaths.”

Dan Costa, who spent about 35 years at EPA studying the impact of air pollution on human health and led its national research program on air quality, climate, and energy, said that “the existing health study gives us a picture of the potential health burden under particular data-center growth and emissions scenarios.”

“But it does not estimate the additional health effects of the 30 federal policy actions EPN documents,” he stressed. “That is the analysis EPA should be doing now: Measuring what these sources actually emit, modeling both local and regional air-quality effects, and translating those changes into health impacts.”

In addition to laying out the Trump policies and their risks, the publication highlights how his agenda on AI data centers conflicts with voters’ wishes. An April poll conducted by YouGov for EPN found that:Just 16% of US voters support making the United States the “AI capital of the world” an EPA priority;

69% of voters are highly concerned about fast-tracking data centers without usual safeguards;

85% of voters say Trump should be tougher on corporations that violate environmental laws; and

by an 8-1 margin, voters say the EPA should prioritize people’s health over reducing pollution regulations.

“You would think a build-out of this magnitude would mean more vigilance from EPA: stronger safeguards to make sure companies control their pollution, more science to understand what this scale will bring, and more monitoring,” said Dr. Lynn Goldman, a pediatrician and former EPA assistant administrator. “Instead, EPA and other federal agencies are doing the opposite.”

The EPN report was published amid mounting calls for Congress to rein in artificial intelligence development in the wake of Jacob Coxon, a researcher at Anthropic who previously worked at OpenAI, quitting, and spotlighting fears within the industry that the rapidly advancing technology “could kill us all by the end of the decade.”

Sen. Bernie Sanders (I-Vt.) and Rep. Greg Casar (D-Texas) have introduced legislation that would permanently ban the development of “superintelligent” AI until a federal body is created to regulate it—and, according to polling results published on Wednesday by Data for Progress, 68% of likely voters in the United States support that proposal.

Sanders has also partnered with Rep. Alexandria Ocasio-Cortez, (D-NY) for the Artificial Intelligence Data Center Moratorium Act, which would pause construction on the facilities “until strong national safeguards are in place to protect workers, consumers, and communities, defend privacy and civil rights, and ensure these technologies do not harm our environment.”

One Disaster After Another: Global Warming is Global Warning


 August 12, 2026

Have we become so desensitized to alarm from the many life-jarring troubles around the world that we can’t see the reality of human-induced global warming? The same way violence in film, television, and 24-7 streamed news has desensitized us to war and conflict, compartmentalized as something from afar. Not in my backyard. I can’t hear you. Well, the heat is here, whether we admit it or not, no more evident than this summer in Europe.

Spain, France, Portugal, Greece, Italy, and the UK have all suffered extreme heat events in 2026, breaking previous temperature records, while much of the northern hemisphere is undergoing increased hot and dry conditions, impacting agriculture and producing more fires. Record surface temperatures above 33 °C (91.4 F) in the Mediterranean Sea (warmer than the Gulf of Mexico) are also intensifying heat waves across Europe. The Romanian navy even blew up a large underwater rock in a controlled explosion to increase flow to the Old Danube river to provide more cooling to the Cernavodă nuclear power plant amid reduced electric grid output. Mitigation and adaptation may be all we have left.

In the 2006 documentary An Inconvenient Truth, Al Gore presented a series of climate disasters in seemingly off-the-radar, underdeveloped countries, but those same disasters are now occurring in developed countries as global temperatures rise and extreme events become more frequent, producing stronger storms, worsening drought that is devastating farms, and generating more virulent fires across wide swathes of land. Amid the worst-ever fire season this past July in Spain and France, former Australian fire and rescue commissioner Greg Mullins stated, “Countries that have always burnt are burning more and countries like the UK, Norway, Greenland that have never burnt are now burning.”

Spain was first to dominate the news cycle this summer as temperatures soared past 40 °C (104 °F) throughout much of the country, intensifying wildfires in Almería that killed 13 people unable to evacuate through instant walls of fire ignited in dried-out vegetation. Wildfires west of Madrid and in Ávila destroyed hundreds of thousands of hectares of land, while some are still burning. One Zaragoza city temperature sign showed 56 °C in direct sunlight and Sumacàrcer in Valencia registered a sensación térmica (feels like) over 60 °C. Increased “desertification” across the Iberian Peninsula is now a major concern.

Spain’s prime minister Pedro Sanchez called a climate emergency “to address the increasingly extreme impacts of climate change,” noting that “climate change denial is the worst fuel” as opposition leaders questioned the reality of human-induced global warming and extreme weather from the continued burning of fossil fuels. The politicization of climate stress is worsening, where ecology is blasted as a new kind of communism.

France especially suffered with 5,700 excess deaths in June, many in Paris among the elderly. In July, in the southwest of France, in the Gironde and Landes regions near Bordeaux, more than 250,000 people were evacuated and 240 homes destroyed amid horrific, out-of-control fires and record-breaking daily temperatures over 40 °C. As the fires threatened the city of Bordeaux, French authorities curtailed the final day of the Tour de France to provide more support.

Because of increased temperatures and longer summers, vegetation is becoming drier, creating more fires and drying out even more land in a horrific climate feedback. Apocalyptic scenes in the Gironde were described with 35-metre “Dantesque” flames as one resident who escaped the fire said, “It was like the end of the world.” Fifty firefighters were injured, while the world saw firsthand the effects of a new type of climate reality, the pirocumulonimbus or “fire cloud” that heats the air even more, spreading toxic ash as dry crisp vegetation is gobbled up. Lightning can also occur, threatening even more fires.

All of Wales was in drought after the driest July in 190 years as well as half of England, causing the natural environment to “deteriorate” and damaging agriculture and food supplies. The UK is undergoing a fifth summer heat wave as the countryside turns from green to brown. All 27 citiesmonitored by the Italian health ministry were under red alert as people were “advised to avoid sunlight, sweet carbonated drinks, coffee, and alcohol.”

Elsewhere, South Korea recorded the highest temperatures ever and issued an outdoor activity alert as temperatures passed 40 °C for five consecutive days. Hong Kong recorded its highest temperatures since 1884. This past year, wildfires began much sooner than usual in Canada, causing smoky skies across southern Ontario and parts of the United States, affecting FIFA World Cup matches and producing the world’s worst air quality in Toronto on July 15. This past week in British Columbia a state of emergency was declared. When does a local emergency become a global emergency?

Numerous regions have suffered unimaginable horrific scenes in the past few years, killing residents, destroying homes, and wiping out large parts of towns as yet another unprecedented fire is added to the record books: Fort McMurray, Alberta (2016), Lytton, British Columbia (2021), Jasper National Park in Alberta (2024). In 2009, 173 people died and thousands of homes were destroyed during Australia’s worst-ever “Black Summer” bushfires. In 2018 in Greece, 104 people died as fires approached Athens. In 2024, over 1,000 fires burnt in Portugal.

Today, BC and the northwest US are under constant threat. Few of us will forget the daily scenes in Los Angeles last year as over 18,000 homes and buildings were destroyed, aided by 100-mph hurricane-force Santa Ana winds. An independent wildfire map that uses data from NASA’s VIIRS (Visible Infrared Imaging Radiometer Suite) shows over 27,000 current wildfires, almost 16,000 labelled as “critical.”

At the same time, oil companies are racking up record profits. The US president supports even more oil production, despite cartoonish comments by the oil industry’s number-1 lobbyist that oil companies are “making too much money,” showing that lawmakers are beholden to profits at all costs. The rah-rah war strategy in Iran that sustains $80/barrel oil prices is a boon to oil producers, including Chevron, ExxonMobil, and BP, shamelessly profiting from yet another war over oil to the tune of hundreds of billions of dollars. The Pentagon is the number-1 consumer of oil on the planet, costing billions of dollars annually and “a stunning volume of pollution.” War is now just another business. Eat, drink, and be merry, tomorrow will be even hotter.

It’s not like we didn’t know. Global warming was forecast as far back as the start of the Industrial Revolution. The French mathematician Joseph Fourier, the Anglo-Irish physicist John Tyndall, and the Swedish chemist Svante Arrhenius all did early work to establish the now well-known, heat-trapping properties of water vapor, carbon dioxide, and methane. Often overlooked, US scientist Eunice Foot was the first to posit that carbon dioxide could heat the air in her 1856 paper, “Circumstances Affecting the Heat of the Sun’s Rays.”

Popular Mechanics has published numerous articles on climate change, including Remarkable Weather of 1911 (1912), Is Our Climate Changing? (1930), Coal Dust Speeds Melting of Ice by Absorbing Sun’s Heat (1940), and What’s Happening to the Weather (1957). American geochemist Wally Broeker coined the term “global warming” in a 1975 Science paper, “Climatic Change: Are We on the Brink of a Pronounced Global Warming?,” stating that “the exponential rise in the atmospheric carbon dioxide content will tend to become a significant factor and by early in the next century will have driven the mean planetary temperature beyond the limits experienced during the last 1,000 years.” We have long known the science and the consequences.

In his 2010 book Eaarth: Making a Life on a Tough New Planet, 350.org’s Bill McKibben wrote that “The planet on which our civilization evolved no longer exists. The stability that produced that civilization has vanished.” Citing numerous examples, including hotter air (holding more vapor), increased rainfall, more desert, more lightening, increased ocean heat (more hurricanes), higher acidic seas, more drought, dry rivers (e.g. Lake Mead), lost seafront, lower farm yields, disappearing glaciers, no more coral reefs (perhaps by 2050), and vanishing species, he noted that more of the earth is “now experiencing a tropical climate.”

And yet every year, greenhouse gases continue to rise, carbon dioxide now at 429.12 ppm and methane at 1937.59 ppb. With a world population of over 8 billion, double 50 years ago, growth-based consumerism is exacerbating a runaway crisis, aided and abetted by profiteering corporations and denialist governments. Rome is literally burning as we fiddle.

So what can we do? Better forest management, warning systems, and fire breaks are all needed. Upon visiting the fire-ravaged Gironde, French president Emanuel Macron compared the situation to World War II and vowed to “rebuild a different kind of forest.” One hopes that includes ending subsidized industrial biomass that falsely accounted for 10% of Europe’s “green” energy.

Citing the buildup to the 2024 Olympics, former Paris mayor Anne Hidalgo championed a progressive green strategy with more green spaces, cycle lanes, and electric buses (1,000 now and counting). Solar canopies that provide both power and shade are now mandatory for large French parking lots.

Less is more: oil, plastic, mindless consumption. But will any of it be enough as temperatures continue to rise? Oddly, the newly reformed Schuman Square outside the EU headquarters in Brussels is mostly concrete, called “Europe’s largest frying pan,”while a green canopy was shelved from the plans,

Increased green energy will help. More solar and wind power has been installed in the past two years than in the previous 20 years. We may see a green grid and 100% EVs by 2050. The exponential growth of cheap renewable energy (95% new energy installations) and the rise of electric vehicles (20% of new car sales) are displacing more fossil fuels year on year.

Each year, electric vehicles cut into the global oil supply. At the current rate of conversion, China’s public transportation will be 100% electric by 2035, displacing more than 1 million barrels of diesel fuel per day. The “inflection point” – the moment of price parity between gasmobiles and EVs – will signal the end, coming soon as battery prices continue to fall. With increased EV adoption, roadside pollution is also being reduced.

We have no choice but to change our ways, sooner than later as our climate worsens. We are already in crisis, never mind a limited petroleum supply that will eventually run out this century. Where once we could choose to change, change is now being forced upon us despite our unwillingness and a callous oil industry spurred on by compliant politicians. The heat is on. The disaster spectacle is real.
