Toxic mine pollution has turned Ohio rivers orange. Now it’s being made into paint.

Rivers could be cleaned up by neutralizing the acidity of AMD, however it’s an costly course of. However two professors at Ohio College have provide you with a strategy to fund the clean-up of polluted rivers by extracting the iron oxide — a substance generally used to make pigments — and turning it into artist-grade paint.

Coal was as soon as an essential a part of Ohio’s economic system and the state produced roughly 2.35 billion tons from its underground mines between 1800 and 2010. However earlier than 1977, when the US launched the Floor Mining Management and Reclamation Act, mines that have been not wanted have been typically merely deserted.
Consequently, most of the mines have grow to be polluters, with AMD affecting 1,300 miles of Ohio streams, in line with the Ohio Division of Pure Sources.

Man Riefler, an environmental engineer and Ohio College professor, has been working to deal with the issue for the final 15 years.

“It is a nuisance and an eyesore and a humiliation actually to the inhabitants. And since it is a poor space, it actually does not get the eye it deserves,” Riefler explains.

Riefler landed on the thought of extracting iron oxide from the polluted water and turning it into shade pigments, which might be bought to additional fund the clean-up of AMD. However he did not know sufficient about paints to find out what made them good high quality.

Coincidentally, a decade in the past, Ohio College artwork professor John Sabraw went on a college tour of acid mine discharge websites and experimented with making paint from a jar of polluted stream water — with out a lot success.

The pair started working collectively to show extracted iron oxide into artist-quality paint. Their collaboration has helped take the thought from “an fascinating little science undertaking” to one thing larger, as Riefler developed a small-scale course of to neutralize the acidity of contaminated streams and extract iron oxide particles — which he says is the predominant steel pollutant in Ohio’s acid mine seeps.

“The fashionable artist is excellent at engineering options to issues,” he says. “I can not inform you what number of instances I obtained to a roadblock and I bounce it off John … he’d provide you with one thing that I did not consider and simply took us to the subsequent degree.”

In 2018, alongside native non-profit Rural Motion, they partnered with paint firm Gamblin to create a restricted run of 500 oil paints. They have been supplied as a reward for supporters of the Kickstarter marketing campaign that funded their research-scale pilot facility. Named the “Reclaimed Earth Colours” set, the paints have been in style amongst artists, says Sabraw, permitting them to include an environmentally acutely aware side of their work.
By their social enterprise referred to as True Pigments, they’re now placing their clean-up mannequin to the take a look at by constructing their first full-scale remedy facility, resulting from be operational in 2024. It is going to be situated on the Truetown discharge, on the Sunday Creek Watershed, a web site in southeastern Ohio closely impacted by AMD, in line with Riefler.

“Each single minute, 1,000 gallons of water is popping out of this deserted mine. It is obtained a variety of iron and it is acidic,” says Michelle Shively MacIver, True Pigments’ director of undertaking growth. “Little or no life can dwell in an space that appears like this.”

As soon as the remedy facility is operational, True Pigments goals to extract roughly 2 million kilos of iron oxide per 12 months and clear up seven miles of stream — ranging from Sunday Creek to the opening of Hocking River — in line with MacIver.

A earlier Rural Motion AMD remediation undertaking that neutralized the acidity of stream water on the west department of Sunday Creek noticed 17 species of native fish return after two years, in line with the NGO. True Pigments is assured that its facility will result in an analogous final result within the Sunday Creek watershed.

“Our hope is that after the chemistry is mounted there, they (fish) will hold swimming upstream. That shall be good for your entire watershed,” MacIver says.

“It is an costly situation”

True Pigments shouldn’t be the primary to extract iron oxide pigments from air pollution. The EnvironOxide vary of pigments has been produced from AMD in neighboring Pennsylvania for 20 years, however Riefler says True Pigments makes use of a distinct technique that wants much less area and is healthier suited to the circumstances at Truetown.
True Pigments has acquired funding from a variety of donors together with the Ohio Division of Pure Sources (ODNR), which has granted the undertaking $3.5 million by means of its Federal Deserted Mine Land Reclamation program. The cash will go in the direction of the primary part of establishing the remedy facility.

Ben McCament, deserted mine land program supervisor on the ODNR, says that between 1999 and 2018, the division spent roughly $32 million on 67 tasks to deal with AMD. “It is an costly situation,” McCament tells CNN. “I feel that is all the time been one of many major challenges. Each web site is exclusive, each web site is troublesome, and it requires long-term funding to deal with it.”

By funding True Pigments, the ODNR hopes as an instance that by means of a public-private enterprise, “we will create a product out of those waste streams after which additionally handle an environmental situation and get better and enhance water high quality that is been affected by AMD for a very long time,” McCament says.

In addition to serving to the surroundings, the hope is that the Truetown facility will present jobs for the area people, and create a provide of iron oxide for different makes use of — reminiscent of the development business, the place it is utilized in bricks, coloured concrete and tiles.

McCament believes True Pigments’ mannequin may doubtlessly be an answer for AMD websites across the US, so long as they’ve “the correct circumstances that might make this specific strategy workable, sustainable and economical.”

Riefler echoes this sentiment. “With a little bit bit extra work, it might be tailored to a variety of totally different locations,” he says. “So it is a first step, and it is a massive one. It is obtained promise for air pollution around the globe.”

Northvolt dilemma: Can European EVs avoid relying on Asian batteries?

Northvolt dilemma: Can European EVs avoid relying on Asian batteries?

Two months before Northvolt filed for bankruptcy in the US, Robin Zeng, known as China’s “battery king”, had a quick but grim answer as to why European battery makers were struggling to make good products.

“They have a wrong design . . . they have a wrong process . . . and they have the wrong equipment. How can they scale up?” the chief executive of CATL told Nicolai Tangen, the head of Norway’s $1.8tn oil fund. “So almost all mistakes together.”

The bleak assessment from the world’s biggest electric vehicle battery manufacturer captures the scale of the failure for the industries behind the critical technology for Europe’s decarbonisation, leaving governments, companies and investors at a loss as to how to recraft the continent’s strategy to compete with China.

“How are we not taking this more seriously? The European car industry is the heartland of European industry’s supposed prowess,” said one long-standing investor in Northvolt after the collapse into US bankruptcy last week of Europe’s biggest battery hope. “The depth of the crisis for the European car industry is almost unlimited. It’s incredibly grim.”

Brussels took its first steps to establish a battery supply chain across Europe in 2017, with Northvolt at the heart of its ambitions. The bloc has since increased its share of the global battery market from 3 per cent to 17 per cent with annual turnover of €81bn in 2023 after spending more than €6bn of the EU budget to support cross-border battery projects and research and innovation.

But in terms of EV batteries, Asian participants including CATL, BYD, and LG Energy Solution and SK On of South Korea, control about 70 per cent of the global market. Many of the 30 gigafactory projects in Europe have also been designed and built with the help of Chinese and Korean companies.

As the EU’s ambitions have faltered, the struggles of Northvolt have come to embody the challenge the continent faces. The bloc wants to continue encouraging costly investments in the clean technologies needed to meet its ambitious climate goals, while at the same time stemming the wave of plant closures and job cuts that are already spreading across the automotive sector and heavy industries. 

“It’s fair to say we’re at a pivotal moment right now,” said Wouter IJzermans, executive director at the Batteries European Partnership Association. 

People involved in the Northvolt saga said options were narrowing for Europe to address its dependence on China and other parts of Asia for the technology and materials that will be critical as the automotive industry transitions to electric vehicles. 

Efforts are still being made by other start-ups such as France’s Verkor and Volkswagen’s battery business PowerCo, but they are facing either diminished ambitions or tougher financing prospects.

PowerCo is considering building just one out of the two production lines previously planned for its plant in Salzgitter in Germany due to slowing market demand.

Verkor counts Renault as its main client and recently finalised a new €1.3bn financing round to back the construction of a plant in the northern French port city of Dunkirk. But its chief executive Benoit Lemaignan said financing talks were arduous on the back of Northvolt’s woes and the slowdown in the growth of electric vehicle sales this year.

“There was a whole fresh round of audit work and validation of the set-up, our chemistry, the machines and all the equipment,” Lemaignan said. “It’s not something automatic, to find financing today. It’s an issue that goes well beyond Verkor, and affects the financing of all of the energy and climate transition industries.” 

In France, there is also Automotive Cells Company, a venture backed by carmakers Stellantis and Mercedes-Benz, and oil major TotalEnergies, which started producing batteries in 2023. But this year ACC paused plans to expand further with plants in Germany and Italy as it considered switching to a lower-cost form of battery technology and adjusted to a slower EV adoption rate. 

“There are expansion phases and crisis phases, if you draw a parallel with other industries. Perhaps we’re living through the first big challenges for Europe’s battery industry. But there will be factories and there will be clients, we’re seeing that more and more,” Lemaignan said.

Consequences from Northvolt’s US bankruptcy filing are already being felt, with carmakers being forced once again to turn to their Asian suppliers to reduce their exposure to its collapse. 

Germany’s Porsche has never confirmed its relationship with Northvolt, but a person familiar with the agreement between the two companies said the Swedish start-up was contracted to make the batteries for the all-electric Porsche 718, scheduled for launch next year.

As Northvolt’s troubles deepened, the sports-car maker began looking for alternative suppliers. While Porsche also buys batteries from South Korea’s Samsung SDI, LGES and China’s CATL, the person added that diversification was a complicated task at relatively short notice.

Northvolt’s demise means the battle for dominance of the European market is likely to play out between Asian battery makers. 

LGES and SK On both have European plants, in Poland and Hungary respectively, while CATL has a factory in Germany and a second site in Hungary due to begin production next year.

But Tim Bush, a Seoul-based battery analyst at UBS, said there was little prospect at present that the Asian battery makers would be able to help the EU to meet its target for 90 per cent of the continent’s EV batteries to be produced locally by 2030.

Bush noted that Korean battery makers were already paring back their investments in Europe, having invested billions of dollars in plants in North America that have been running at low utilisation rates because of lower than expected consumer demand for EVs.

Potential Chinese battery investments on the continent were also likely to be complicated by the ongoing trade dispute between Brussels and Beijing over EU tariffs on Chinese electric vehicles, he added.

“The Koreans are not expanding, the Chinese have suspended construction and Europe’s new entrants are dropping like flies,” said Bush.

Against such obstacles, the European Commission is weighing plans to require Chinese developers to have plants and bring their intellectual property to Europe in order to access EU subsidies, the FT has previously reported. 

With European start-ups still behind in their ability to manufacture batteries at scale, industry executives say the only solution may be to continue their reliance on Asian participants until homegrown companies can absorb technology knowhow on battery chemistry, mass production and equipment manufacturing.

“We need to find a deal with China because we won’t be able to compete . . . without the support of the Chinese companies that control the mining industry, chemicals, refining and their capacity and competence,” Luca De Meo, Renault’s chief executive, told reporters last month.

But the dilemma is how long Europe needs to wait for the technology transfers to complete, and whether it would already have lost the race by then.

“If you really zoom out, what does Europe want to be? I really question whether Europe wants to give up yet another industry like it did with solar panels. Europe is not a leader in AI. I want my kids to grow up somewhere where there are a lot of jobs,” said a Northvolt executive.

Two members of a Dartmouth College fraternity and a sorority have been charged in the death of a student who was found dead in a river over the summer after attending an off-campus party where alcohol was allegedly served to people who were under 21.

Won Jang, a 20-year-old who was a student at the college and a member of the Beta Alpha Omega fraternity, attended a party off campus in July held by Alpha Phi, a sorority, the Hanover Police Department in New Hampshire said in a statement Friday. The department said Jang and most of the other attendees were under 21 years old and drinking alcohol that was bought and served by Beta Alpha Omega members who were over 21.

After the party, several attendees decided to go for a swim in the Connecticut River, but when a heavy rainstorm occurred many of them left in groups.

“No one in these groups noticed that Jang was unaccounted for. It was confirmed via multiple interviews, to include Jang’s family, that he could not swim,” Hanover police said in a statement.

An autopsy report later determined that Jang’s cause of death was drowning, according to police. His blood alcohol level was .167, the department said. That amount is more than twice the state’s legal amount allowed for drivers 21 and older.

Jang was an undergraduate student from Middletown, Delaware studying biomedical engineering and was a student mentor, according to The Dartmouth. Scott Brown, dean of the college, said Jang “wholeheartedly embraced opportunities at Dartmouth to pursue his academic and personal passions,” according to the paper.

Two members of Beta Alpha Omega fraternity were each charged with a misdemeanor for providing alcohol to persons under 21 years old. The Alpha Phi sorority was also charged with a misdemeanor violation of facilitating an underage alcohol house, the police also said.

Neither Alpha Phi nor Beta Alpha Omega responded to a request for comment.

Dartmouth College said both the Alpha Phi chapter on campus and Beta Alpha Omega were “immediately suspended” after Jang’s death and an internal investigation was launched. The suspensions are still in effect “pending the results of Dartmouth’s internal investigation and conduct process” that the college said is still underway.

“Dartmouth has long valued the contributions that Greek organizations bring to the student experience, when they are operating within their stated values and standards,” the college said in a statement to NPR. “These organizations, as well as all Dartmouth students and community members, have a responsibility to ensure Dartmouth remains a safe, respectful, equitable, and inclusive community for students, faculty, and staff.”

The college also said that because of federal law it “cannot comment on individual disciplinary matters.”

US retailers stretch out Black Friday deals to lure flagging shoppers

Stay informed with free updates

US retailers are extending their one-day seasonal Black Friday discount offers into a sales event lasting weeks in a bid to tempt US consumers to keep spending, as data suggests that their spree which has driven economic growth is beginning to falter.

Walmart, Amazon, Target and Macy’s are among the US retailers already offering deep discounts under the banner of Black Friday, long before it actually arrives this week.

Despite this, general merchandise unit sales were down 3 per cent year-on-year in the week ending 16 November according to data from Circana, which compiles retail point-of-sale data.

The National Retail Federation forecasts that winter holiday sales will reach almost $1tn in the US in November and December, a record $902 a head. But the rate of spending growth is expected to be about 2.5-3.5 per cent, the slowest since 2018.

“We’re seeing this drag-out of incentives to try to widen the window within which [retailers] can draw more consumers,” said Gregory Daco, chief economist at adviser EY Parthenon. “The likely reality in this holiday season is that we see fairly subdued sales because volumes are growing, but at a moderate pace — and [retailers have] much less pricing power.”

Retailers were “incentivising via discounts and different forms of promotions” for those at the lower end of the income spectrum while also “trying to grab higher-income individuals to make purchases during this wider window”, he said.

Although headline inflation has ebbed from the historic highs of the past couple of years, consumers “remain extremely frustrated by the persistence of high prices”, the University of Michigan said this week in a monthly survey.

Consumer spending has been the main driver of America’s robust economic growth in recent months. But consumer confidence is still well below the long-run average, sentiment surveys show.

The prospect of a fresh round of tariffs under Donald Trump’s incoming presidency raises the risk that inflation could take off again, economists have warned — posing a fresh drag on sentiment.

“Donald Trump’s return to the White House with a Republican majority [probably leads] to higher inflation, slower GDP growth and increased budget deficits,” Roland Fumasi, food and agribusiness analyst at Rabobank, said in a note.

If Trump increases tariffs, that would “lead to a rebound in inflation and a slowdown in economic growth”, he said.

“The negative impact on growth could be mitigated by tax cuts and deregulation by a Republican Congress. However, this would increase the budget deficit and reinforce inflation, especially in combination with reduced immigration,” he added.

Black Friday is one of the busiest times of year for consumer goods stores, and the period between Thanksgiving and Cyber Monday — the Monday following the holiday, when electronics vendors discount goods — is critical to retailers’ annual revenue.

NRF chief economist Jack Kleinhenz said that households’ finances were in “good shape”, offering “an impetus for strong spending heading into the holiday season”, although “households will spend more cautiously”.

Brian Cornell, Target chief executive, told analysts this week that consumers were becoming “increasingly resourceful” in the way that they shopped, “focusing on deals and then stocking up when they find them”.

The store group, which disappointed Wall Street this week by forecasting flat sales in the fourth quarter, ran a three-day “Early Black Friday” promotion in early November. On Thursday it launched a promotion titled “Black Friday deals” which will last to the end of the month, including items such as half-price Christmas trees and headphones.

Walmart, the world’s largest retailer, launched the first of two week-long “Black Friday Deals” events on November 11. The second will begin on Monday, offering markdowns on televisions, iPhones, toys and jeans, among other items.

Amazon’s “Black Friday Week” began on Thursday. Home Depot’s “Black Friday Savings” offer lasts from November 7 to December 4.
