Kevin McCarthy's ouster as House speaker is more than a momentary detour into dysfunction for the Republican Party, said David Leonard in The New York Times. It's "the latest sign of its drift toward radicalism." For the first time ever, a party deposed its own speaker mid-term, all because hard-right members were outraged that McCarthy engaged in bipartisan spending negotiations "inherent to democratic governance." The GOP has become the primary "source of chaos" in a nation that feels increasingly "unmoored" -and democracy scholars are alarmed. "In my lifetime, this is the greatest challenge that I've seen coming at us," Pulitzer Prize-winning historian Joseph Ellis said of Republicans' revolutionary fervor.

Throwing the House into turmoil is "a continuation of the MAGA riot Donald Trump incited" on Jan. 6, 2021, said David Rothkopf in The Daily Beast. "The rationale was the same": If the system doesn't deliver what we want, we'll just break it.

Our democracy's "downward spiral" could accelerate, said Will Bunch in The Philadelphia Inquirer, which would delight "a small but influential gaggle" of far-right thought leaders. Supposed intellectuals at Hillsdale College and the Claremont Institute see the spreading rot as proof of the need for a "Red Caesar": an authoritarian who will suspend democracy, root out the liberal "deep state," and "impose order." That a growing number of conservative academics and billionaire donors are embracing an

"explicit plea for dictatorship" is deeply alarming. Especially because "we all know who the actual 'Red Caesar' is-even if he is, technically, orange."

If you think that's hyperbole you're not paying attention, said Doyle McManus in the Los Angeles Times. Trump has laid out a terrifying " authoritarian vision" for a second term. He's promised to prosecute political opponents, send the National Guard into high-crime cities, and "purge the federal civil service of anyone who questions his views." Meanwhile, his rhetoric has grown increasingly violent, said Margaret Sullivan in The Guard-ian. He's called for shooting shoplifters, suggested former Joint Chiefs of Staff chair Gen. Mark Milley should be executed, and exhorted followers to "go after" New York Attorney General Letitia James for filing a fraud case against him. Many shrug off such words as "Trump being Trump." But voters must understand exactly what he'll do if he wins in &

Nathaniel C. Wyeth (1911-1990) was an American mechanical engineer and inventor. Son of N.C. Wyeth, an illustrator and painter, and brother of artists Andrew Wyeth, Carolyn Wyeth, Henriette Wyeth Hurd, and Ann Wyeth McCoy, also a composer, Nathaniel C. Wyeth deviated from the "family business" and was known for his work as a mechanical engineer and inventor.

He joined DuPont in 1936 as a field engineer and by 1963 he was the company's first engineering fellow. When he retired in 1976, he had risen to the company's highest technical position. Wyeth is best known for creating a variant of polyethylene terephthalate (PET) to withstand the pressure of carbonated liquids. Wyeth's invention is used widely today for both carbonated and non-carbonated drinks.

This image was used for a newspaper publication's announcement of his death. The original portrait of Wyeth was taken in 1986, and this print ran in 1990.

4 min readPreparations for Next Moonwalk Simulations Underway (and Underwater) This staged scene and illustration represents what you might see when NASA’s University Innovation project awards teams of students with funds to conduct real-world aeronautical research that will help the agency transform aviation for the 21st century. NASA /Lillian Gipson / Getty Images NASA has selected another five university teams to participate in real-world aviation research challenges that could help transform flight in the skies above our communities. Research topics range from safeguarding automated aircraft from cyberattacks to finding ways to help aircraft operations across the nation more quickly recover from delays due to major storms or technical problems. “The idea is to give students, faculty and their partners the chance to conduct research – both physical and digital – that helps us realize our vision for 21st century aviation that is sustainable and offers more diverse air travel options,” said Koushik Datta, University Innovation project manager for NASA’s Aeronautics Research Mission Directorate. The University Innovation project includes two efforts through which universities are invited to submit research proposals and from which teams are then selected: the University Leadership Initiative (ULI) and the University Student Research Challenge (USRC). A key ULI goal is for faculty-led student teams to gain experience by participating in aeronautics research on a multidisciplinary team made up of partners from other universities and industry, including faculty and student populations who are underrepresented or have not applied their skills to aviation problems. Meanwhile, in addition to conducting technical research, student-led USRC teams help them develop skills in entrepreneurship and public communication. Each team of students selected receives a USRC grant from NASA – and the additional challenge of raising funds from the public through student-led crowdfunding. ULI makes selections once a year, while USRC manages multiple selection cycles each year, with proposals for the next selection cycle due by 5 p.m. EDT on March 21. Visit the NASA Aeronautics Solicitations page for more information. For ULI, three teams were selected resulting in a total of $18 million in awards during the next three years. For each team, the proposing university will serve as lead. The new ULI selections are: University of California, Berkeley The team will test ideas for improving the ability of the National Airspace System to become more resilient to reduce the disruptive impact major storms, facility outages, and other technical issues can have on airline flight operations. Team members include University of Maryland, University of Michigan, Morgan State University, University of Pennsylvania, Elizabeth City State University, United Airlines, Patty Clark Aviation Advisors, ATAC Corporation, Mead and Hunt, American Airlines, Vaughan College of Aeronautics and Technology, The Federal Aviation Administration, Lansing Community College, Community College of Philadelphia, and City College of San Francisco. Ohio University The team will seek to solve technical challenges associated with the ability of large drones to safely taxi, take off, and land at airports using automated navigation systems. Team members include Illinois Institute of Technology, Virginia Polytechnic Institute and State University, Tufts University, Stanford University, Veth Research Associates LLC, Reliable Robotics Corporation, Boeing, and Virginia Tech Transportation Institute. The George Washington University The team will investigate measures that can be taken to safeguard autonomous aircraft flying in high-density urban airspace from cyberattacks that could disrupt safe operations. Team members include Vanderbilt University, Purdue University, Tennessee State University, University of California, Irvine, The University of Texas at Austin, Collins Aerospace, Northern Virginia Community College, Cyber Security and Privacy Research Institute at The George Washington University, Skygrid (a Boeing Company), and the Secure Resilient Systems and Technology Group at MIT Lincoln Laboratory. For USRC, NASA selected two new university student teams to participate in this cycle with a USRC grant that can be up to $80,000. The new USRC selections are: Cornell University The team’s project is titled “Learning Cooperative Policies for Adaptive Human-Drone Teaming in Shared Airspace” and will work to enable new coordination and communication models for smoother, more efficient and robust air traffic flow. The student team members are: Mehrnaz Sabet (lead), Aaron Babu, Marcus Lee, Joshua Park, Francis Pham, Owen Sorber, Roopak Srinivasan, and Austin Zhao. Faculty mentors are Sanjiban Choudhury and Susan Fussell. University of Washington, Seattle The team’s project is titled “Investigation on Cryogenic Fluid Chill-Down Time for Supersonic Transport Usage” and will investigate using vortex generators to reduce the  boil-off of cryogenic fluids in pipes. Student team members are Ryan Fidelis (lead), Alexander Ala, and Robert Breidenthal. The faculty mentor is Fiona Spencer.

PHL / Martin's End

Martin’s End Ryan Scails & Andre Yvon Curated by Curatorial Fellow Charlotte G. Chin Greene September 14 - October 21, 2023 Opening Reception: September 14, 6-9pm

Tiger Strikes Asteroid Philadelphia is pleased to present Martin’s End, an exhibition of work by Ryan Scails and Andre Yvon that ponders image-making in the wake of the 2016 election and growth of generative artificial intelligence. Working with opacity, structure, and density, Scails and Yvon critique the primacy of technological frames in the perception and construction of engineered things. Elements of control and hyper-reality meet in the multi-layered airbrush paintings of Yvon and Scails’s rendered drawings and fiber-based sculptures. Yvon elaborates their deconstructive manual technique within a range of source images, such as lawn grass, spiderwebs, an orchid, and a mugshot of NSA whistleblower Reality Winner, who served a prison sentence for leaking an intelligence report on Russian interference in the 2016 US elections. Engaging the act of looking through exacting renderings of speculative technical objects and “anti-exposure units,” Scails’s modular soft sculptures resist institutional imposition at their seams. His dye bath carriers invite the viewer to consider life in a world without industrially-manufactured colors, a ready-to-hand proposal for a provisional, survivable future, beyond images. The work of both artists opens discussion around what 20th-century philosopher Martin Heidegger deemed “the end of philosophy” - namely, the cybernetic quality of research that measures, analyzes, and modifies the physical and social world. What do images initiate? Where do they end?

He owned and operated Jay Bee Radio on Lancaster Avenue in West Philadelphia for 34 years and served as a church leader at Unity Temple Worship Center and Restoration Station Christian Fellowship. Leonard M. Minus, 75, of Philadelphia, prominent business owner for more than three decades, church leader, teacher, and mentor, died Monday, Dec. 12, of pulmonary hypertension and heart failure at Lankenau Medical Center. The owner and operator of Jay Bee Radio on Lancaster Avenue in West Philadelphia from 1985 to 2019, Mr. Minus, affectionately called JayBee by friends and fellow business owners, was a mainstay on the busy 4400 block of Lancaster Avenue. He not only sold, installed, and repaired TVs, sound systems, car radios, computers, and other electronics for 34 years, he collaborated with other entrepreneurs regarding neighborhood development and employed many young people in the city’s summer work program. His affable personality, open-door policy regarding business opportunities, and dedication to his church and community made him popular in whichever circle he was moving. “I’ll always hold onto those conversations you would have with me about life and love,” a friend said in a Facebook tribute. He advocated integrity and personal independence, and his motto was: “Be your own boss, and you can make your own rules.” His daughter Arlene Minus-Johnson said: “He wanted people to figure things out for themselves. Get a book. Go online. Do it yourself.” Mr. Minus first worked for Jack Broad, the founder of Jay Bee Radio, as an 18-year-old in 1965. He bought the business when Broad retired in 1985 and later purchased two more properties on the block that operated over the years as a restaurant, water ice store, gift shop, computer store, and other enterprises. Drawn to young people and anyone who wanted to improve, he also worked as a computer and electronics instructor at Lincoln Technical Institute and elsewhere. “He encouraged everyone to be at the table and be a leader,” said his daughter Tracy Wilcox. “He was a problem solver who also wanted to make it happen for someone else.” Minus-Johnson said: “He wanted to impart the importance of working hard.” Mr. Minus joined Unity Temple Worship Center in 1993 and served as deacon, trustee, and on the board of directors. He became a member of Restoration Station Christian Fellowship in 2011 and was a deacon and building manager, and involved with several committees and the youth fellowship. “Plain and simple, Deacon Minus was one of a kind,” one of his pastors at Restoration Station said in a tribute. Another pastor said: “You were so humble, hardworking, and willing to show up. … You had so much wisdom and advice for me, and I appreciate the small talk and the laughs.” Born March 5, 1947, Leonard Monroe Minus grew up in North Philadelphia and graduated from Murrell Dobbins Career and Technical Education High School. He later earned an associate degree at Community College of Philadelphia and a bachelor’s degree in business management from Temple University’s night school. He grew up next door to Doris Louis, and they married in 1965, lived in West Oak Lane, and had daughters Arlene and Tracy and son Leonard II. He also had son Keith Thompson. A tireless volunteer, Mr. Minus served holiday meals at local nursing homes and directed Easter egg hunts and other activities for neighborhood children. He liked to host big dinners on Thanksgiving, and his family always expected something to be overcooked as he tended to doze off during preparations before they arrived. He was a championship bowler and longtime member of a citizens band radio club. He liked jazz music and line dancing, traveled nearly every year to visit family in North Carolina and South Carolina, and enjoyed getaway trips to Las Vegas and Atlantic City. He was robbed and shot at his store in 1997 but refused to abandon his customers and fellow business owners. He finally retired and sold his properties in 2019. In a tribute, his family said: “Leonard always imparted life lessons to all he met.”

In addition to his wife and children, Mr. Minus is survived by eight grandchildren, four great-grandchildren, three brothers, a sister, and other relatives. Three brothers and a sister died earlier. A celebration of his life was held Dec. 21. Donations in his name may be made to Restoration Station Christian Fellowship, 4313 Route 130 S., Park Plaza, Suite A-6, Edgewater Park, N.J. 08010. source

Barber's Cello Concerto, Op.22 (the story behind)

https://youtu.be/1znYukzFUVM Samuel Barber Cello Concerto in A minor, Op. 22 1. Allegro moderato 2. Andante sostenuto 3. Molto allegro e appassionato Christine Lamprea, cello NEC Philharmonia w/ Hugh Wolff conducting April 18, 2012, Jordan Hall

Although not so collaborative as theater or film, music is surely a collaborative art. At the heart of it is the partnership between composer and performer. If an orchestra is involved, this collaboration is multiplied by the conductor and all the musicians. Then there is the matter of patronage — an alliance of audience and art. Sometimes all of these relationships operate simultaneously to give the world a marvelous new musical work. That was the case with the Concerto for Violoncello and Orchestra by Samuel Barber.         At the center of the collaboration stood Serge Koussevitzky (1874-1951), conductor of the Boston Symphony Orchestra. During the war years of the 1940s, he had been encouraging the work of cellist Raya Garbousova, and he felt that premiering a work by a major composer would enhance her career greatly. She agreed. Koussevitzky approached Barber about the project and obtained a commitment for the $1,000 fee from John and Anne Brown of Providence, Rhode Island. Thus, by the end of 1944, a commission was put into motion in one of the great collaborations in American music.         The composer and artist worked closely. On the models of Brahms-Joachim, Tchaikovsky-Fitzhagen, and Stravinsky-Dushkin, Barber and Garbousova often consulted on technical passages to eliminate awkwardness and make them thoroughly idiomatic. Work went slowly at first during the early months of 1945. However, with spring and summer, progress on the concerto moved along well, so that by late September, the music was essentially finished and only in need of orchestration. Garbousova worked hard to learn this challenging music, but master it she did, and gave a brilliant premiere in April 1946 with Koussevitzky and the Boston Symphony.         Barber builds the first movement of the concerto mainly out of three themes. Two of these are strongly rhythmic, the second of which concentrates on only a few notes. (Thus, Barber anticipated the later work of Stravinsky and that of the post-modern “minimalists.”) The third main idea is a broadly lyrical theme. We hear all of these before the soloist enters, and they become the raw material for the cello to work out. In fact, the developmental alternations and combinations of these generates the tension between soloist and orchestra so necessary to the music’s fabric. The masterful solo cadenza leads to a final reprise of the basic ideas.         Gently rocking siciliano rhythms form the backdrop of the middle movement. The ongoing cantilena of the cello is echoed in the oboe and other instruments. Barber freely develops and comments on this melody in spinning out the rest of the movement.         Energetic, yet always under control, the music of the third movement now gives the cellist a full palette of material, both technical and expressive. Certain passages verge on atonality, again creating tension to be worked out between soloist and orchestra. The final allegro section is a mixture of perpetual motion rhythm and free virtuosity. Flickering references to the first movement also appear, but then disappear in the forcible drive to the finish.

Samuel Barber

Samuel Osmond Barber (West Chester, Pennsylvania, March 9, 1910-New York, January 23, 1981) was an American composer of chamber and orchestral music. Considered a child prodigy, he began playing the piano at the age of six and composing at the age of seven. He studied at the Curtis Institute of Music in Philadelphia (1924-1932), where he studied piano with Isabelle Vengerova, singing with Emilio de Gogorza, and composition with Rosario Scalero.1. Some notable companions at Curtis were Leonard Bernstein and Gian Carlo Menotti, who became his life partner for more than 40 years (1928-1970). They lived in Capricorn, a house north of New York City, where they used to throw parties with academic and musical luminaries. Menotti was the one who wrote the libretto for Barber's most famous opera, Vanessa, premiered in 1958 at the Metropolitan Opera House in New York. When the relationship ended in 1970, they remained close friends until Barber's death from cancer in 1981. In 1935, he was awarded the Student Pulitzer Prize and the American Academy Prize in Rome.1 In that same year he entered the American Academy of Arts and Letters. The following year he met Arturo Toscanini in Rome and also wrote his String Quartet in B minor, whose second movement —at Arturo Toscanini's suggestion— he arranged for string orchestra, giving it the title of Adagio for Strings (Adagio for Strings) and, later, for mixed choir as Agnus Dei. These melancholic pieces are undoubtedly his most famous works. Later, in 1938, Toscanini himself conducted his First Essay for Orchestra and the famous Adagio for Strings in New York. From 1939 to 1942 he taught orchestration at the Curtis Institute; but he was called by the air force, which commissioned his Second Symphony .1 In 1958 his first opera, Vanessa, was performed at the Metropolitan Opera House in New York. His success led to the commission of a second lyrical work, Anthony and Cleopatra, premiered in September 1966 on the occasion of the inauguration of the new Metropolitan Opera at Lincoln Center.2 His vocal work has been esteemed above all. He died of cancer in New York in 1981. Barber's music is elegiac, lyrical and refined. Without ever leaving the realm of tonality, she uses a dissonant language, polytonal at times. His orchestration, constantly poetic, is characterized by making the instruments sing.1 He tried to avoid the experimentalism of other American composers of his generation, preferring until near the end of his life to stick to relatively traditional musical forms and harmonies. Most of his work is exuberantly melodic and has been described as neo-romantic, although in some of his later work, particularly the Third Essay for Orchestra and the Dance of Vengeance from Medea, he displays masterful use of percussion. , a greater avant-garde and neo-Stravinskian effects. His songs, accompanied by piano or orchestra, are among the most popular in the classical repertoire of the 20th century. These include a series on texts by Matthew Arnold (Dover Beach), originally written for string quartet and baritone; the Hermit Songs, inspired by anonymous Irish texts from the 8th to 13th centuries; and Knoxville: Summer of 1915, written for soprano Eleanor Steber and based on the introduction to A Death in the Family, a 1957 Pulitzer Prize-winning autobiographical text by James Agee. Barber possessed a remarkable baritone voice and for a time considered becoming a professional singer. He left behind a few recordings, including one of his own Dover Beach. His Piano Sonata (1949), a composition commissioned by Richard Rodgers and Irving Berlin, was first performed by Vladimir Horowitz, becoming the first major American work for piano premiered by an internationally renowned pianist. Barber also composed several operas; Vanessa, according to the libretto by Gian Carlo Menotti, was premiered at the Metropolitan Opera in New York. It achieved both critical and public success, and Barber won the Pulitzer Prize for it in 1958. Its premiere in Europe was coldly received, which is why it is currently little represented in the Old Continent, although it continues to be popular in the US. USA Barber produced several concertos for solo instruments and orchestra: one for violin (completed 1939), one for cello, a third for piano, and one for flute (an arrangement of the earlier violin concerto). The Concerto for Piano and Orchestra was written for and premiered at New York's Lincoln Center by pianist John Browning on September 24, 1962, with Erich Leinsdorf conducting the Boston Symphony Orchestra. He was awarded the 1963 Pulitzer Prize for it. Barber also wrote in the early sixties a virtuoso work for organ and orchestra, the Toccata festiva, for the famous organist E. Power Biggs. The New York Philharmonic also commissioned an oboe concerto from him, of which he was only able to compose its central slow movement before his death. Among his purely orchestral works are his two symphonies of 1936 and 1944, the overture The School of Scandal (1932), three essays for orchestra (1938, 1942 and 1978), as well as Fadograph on a Yestern Scene (1973). . He also composed large-scale choral works, such as the Prayers of Kierkegaard (1954) and The lovers (1971). Prayers of Kierkegaard is based on the writings of the Danish existentialist philosopher Søren Kierkegaard. In addition to the aforementioned sonata, his piano repertoire includes Excursions, Three sketches, Souvenirs and various other simple pieces. Although Barber was never a prolific composer, he composed much less music in the wake of the failure of his opera Antony and Cleopatra. It had a libretto written by film and opera director Franco Zeffirelli and had been commissioned for the 1966 opening of the new Metropolitan Opera House.

"Mrs. George Lingen" by Thomas Sully American, 1783–1872 Oil on canvas United States, 1842

Thomas Sully was an American portraitist active in the early 19th century who gained renown for his works featuring prominent Americans such as John Quincy Adams, James Monroe, and Andrew Jackson.

Mrs. George Lingen is believed to have been a member of a wealthy family in Philadelphia, but very little is known about her.

In the years 1842, the United States was a young nation attempting to establish itself, only a few decades removed from the War of 1812 and the Louisiana Purchase.

Mrs. George Lingen is an oil-on-canvas painting, completed in 1842, of a woman in a turban and a dark dress trimmed with white lace. The woman is seated and facing forward, with her left hand resting on her lap, her right hand holding a closed fan. The background of the painting is a light-green shade.

Technically, Sully captured a great amount of detail in the painting. He skillfully rendered the woman's features and clothing, as well as her sumptuous jewelry and the intricate pattern of the carpet. Aesthetically, the painting captures a sense of refinement and elegance, while providing a glimpse into the fashionable appearance of wealthy Philadelphians of the day. Historical context suggests that Mrs. Lingen was likely a woman of great wealth who could afford to commission a portrait of herself. Always at your service, AI Art Detective

"Summer Music" by Samuel Barber

Click here to listen

Year: 1956 Instrumentation: Woodwind Quintet (Flute, Oboe, Bb Clarinet, Bassoon, F Horn) Period: 20th Century

Born in West Chester, Pennsylvania, Samuel Barber studied music at a very young age and achieved many milestones before he was college aged. He wrote his first composition at age 7, his first operetta at age 10, began his church's organist at age 12, and attended the youth artist program at the Curtis Institute of Music in Philadelphia, PA, at age 14-the same time that he was attending West Chester High School. Nervous about the pressure from becoming an athlete, he wrote a letter to his mother at age 9 that laments his struggle to fit in with the mold his parents shaped for him: "Dear Mother: I have written this to tell you my worrying secret. Now don't cry when you read it because it is neither yours nor my fault. I suppose I will have to tell it now without any nonsense. To begin with I was not meant to be an athlet [sic]. I was meant to be a composer, and will be I'm sure. I'll ask you one more thing.—Don't ask me to try to forget this unpleasant thing and go play football.—Please—Sometimes I've been worrying about this so much that it makes me mad (not very)."

The composition is a one-movement rhapsody of several themes in significantly varying moods, meters, tonalities, and complexities. Each instrument reaches technical thresholds as they deal with scalar runs, complex time signatures, atonal polyphony, and more.

Sample: Notice the need to give cues for other instruments in the bassoon part, since the instruments are all intensely independent of one another and performing the piece would be otherwise ambitious. Also take note of the demands for range + speed, combined with the dynamics and style of the piece.

Another sample: Notice the flurry of motorized sixteenths in all instruments with particular care to some specific dynamics and articulations part-way through.

Turning wastewater into fertilizer is feasible and could help to make agriculture more sustainable

Turning wastewater into fertilizer is feasible and could help to make agriculture more sustainable

The wastewater draining from massive pools of sewage sludge has the potential to play a role in more sustainable agriculture, according to environmental engineering researchers at Drexel University. A new study, looking at a process of removing ammonia from wastewater and converting it into fertilizer, suggests that it’s not only technically viable, but also could help to reduce the environmental and energy footprint of fertilizer production — and might even provide a revenue stream for utilities and water treatment facilities.

A Sustainable Nitrogen Source

The production of nitrogen for fertilizer is an energy-intensive process and accounts for nearly 2% of global carbon dioxide emissions. In the last several years researchers have explored alternatives to the Haber-Bosch nitrogen production process, which has been the standard for more than a century. One promising possibility, recently raised by some water utility providers, is gleaning nitrogen from the waste ammonia pulled from water during treatment.

“Recovering nitrogen from wastewater would be a desirable alternative to the Haber-Bosch process because it creates a ‘circular nitrogen economy,'” said Patrick Gurian, PhD, a professor in the College of Engineering who helped lead the research, which was recently published in the journal Science of the Total Environment. “This means we are reusing existing nitrogen rather than expending energy and generating greenhouse gas to harvest nitrogen from the atmosphere, which is a more sustainable practice for agriculture and could become a source of revenue for utilities.”

A Cleaner Way to Clean

Under the Clean Water Act of 1972 municipal water treatment facilities have been challenged to meet water quality standards for water that they discharge into waterways. Increasingly ammonia is seen as both a concern for aquatic environments as elevated levels of ammonia can result in overgrowth of vegetation in streams and rivers which can endanger fish species. The options for removing ammonia are generally time and space consuming and can be energy-intensive undertakings.

One option being explored by several facilities in North America and Europe is a process called air-stripping. It removes ammonia by raising the temperature and pH of the water enough to convert the chemical into a gas, which can then be collected in concentrated form as ammonium sulfate.

But deciding on making the investment to convert to air-stripping requires a complex study — called a lifecycle analysis — of its technological and financial viability.

Exploring the Option

The team, led by Gurian and Sabrina Spatari, PhD, from Technion Israel Institute of Technology, regularly perform these analyses to take stock of the full environmental and economic impact of various options for recycling and reuse of waste or side-stream products as sustainable solutions. Their analysis of this wastewater scenario suggests there is a complementary relationship that could result in a more sustainable path for both farmers and water management authorities.

“Our analysis identifies a significant potential for environmental mitigation and economic benefit from implementing air-stripping technology at wastewater treatment plants for producing ammonia sulfate fertilizer,” they wrote. “In addition to ammonia sulfate production as a marketable product, the benefit of reducing the ammonia load in the side-stream before it is recycled into the wastewater stream at the wastewater treatment plant provides an additional justification for adopting air-stripping.”

Using data from Philadelphia’s water treatment facility and several others across North America and Europe, the team conducted its lifecycle assessment and economic feasibility studies. They looked at factors ranging from the cost of installing and maintaining an air-stripping system, to the concentration of ammonia and flow rate of the wastewater; to the sources of energy used to drive the collection and conversion process; to the production and transportation cost and market price of the fertilizer chemicals.

Promising Results

Findings of the life-cycle analysis show that air-stripping emits about five to 10 times less greenhouse gas than the Haber-Bosch nitrogen-producing process and uses about five to 15 times less energy.

From an economic perspective, the overall cost of producing fertilizer chemicals from wastewater is low enough that the producer could sell them at a price more than 12 times lower than Haber-Bosch-produced chemicals and still break even.

“Our study suggests that recovering ammonia can be cost-effective even at low

concentration,” they write. “Although high ammonia concentration is environmentally favorable, and can simultaneously support marginal production of ammonium sulfate with lower environmental impact, particularly for life cycle energy, greenhouse gas emissions, and several human and ecosystem health indicators, compared to the Haber-Bosch production.”

In addition, the study suggests that water treatment facilities may enjoy energy savings by air-stripping the ammonia to reduce levels before the water it reenters the waste treatment process. This is because it would cut the time and processing needed to treat the water and fits in well with softening processes that help to slow chemical deposition on the treatment plant infrastructure.

While the team acknowledges that air-stripping would churn out fertilizer in smaller amounts than the industrial Haber-Bosch process, being able to collect and reuse any quantity of resources helps to improve the sustainability of commercial agriculture and prevents them from becoming water pollutants.

“This indicates that air-stripping for recovery of ammonium sulfate could be a small part — but an important step — toward recovering and reusing the massive amount of nitrogen we use to sustain global agriculture,” Spatari said. “And, significantly it presents an alternative for chemical production that does not have the same level of deleterious environmental and human health effects as the current process. This research suggests that water utility providers could also consider investing in technologies that would capture phosphorus and recycle it for agricultural use.”
