New way to turn sewage into biofuel within minutes!

November 3, 2016

Washington, Nov 3: Sewage treatment plants may soon turn human waste into fuel, thanks to a new technology that mimics the conditions the Earth uses to create crude oil - achieving in minutes something that takes Mother Nature millions of years.fuelfromsewa

The technology, hydrothermal liquefaction (HTL), creates a material similar to petroleum pumped out of the ground, with a small amount of water and oxygen mixed in.

This biocrude can then be refined using conventional petroleum refining operations, researchers said.

According to researchers from the US Department of Energy's Pacific Northwest National Laboratory (PNNL), wastewater treatment plants treat about 34 billion gallons of sewage every day.

That amount could produce the equivalent of up to about 30 million barrels of oil per year in the US.

PNNL estimates that a single person could generate two to three gallons of biocrude per year.

Sewage, or more specifically sewage sludge, has long been viewed as a poor ingredient for producing biofuel because it is too wet.

The approach being studied by PNNL eliminates the need for drying required in a majority of current thermal technologies which historically has made wastewater to fuel conversion too energy intensive and expensive.

HTL may also be used to make fuel from other types of wet organic feedstock, such as agricultural waste.

Using HTL, organic matter such as human waste can be broken down to simpler chemical compounds.

The material is pressurised to 3,000 pounds per square inch - nearly one hundred times that of a car tire.

Pressurised sludge then goes into a reactor system operating at about 350 degrees Celsius.

The heat and pressure cause the cells of the waste material to break down into different fractions - biocrude and an aqueous liquid phase.

London/Milan, Jun 2: World Health Organization experts and a range of other scientists said on Monday there was no evidence to support an assertion by a high profile Italian doctor that the coronavirus causing the COVID-19 pandemic has been losing potency.

Professor Alberto Zangrillo, head of intensive care at Italy's San Raffaele Hospital in Lombardy, which bore the brunt of Italy's COVID-19 epidemic, on Sunday told state television that the new coronavirus "clinically no longer exists".

But WHO epidemiologist Maria Van Kerkhove, as well as several other experts on viruses and infectious diseases, said Zangrillo's comments were not supported by scientific evidence.

There is no data to show the new coronavirus is changing significantly, either in its form of transmission or in the severity of the disease it causes, they said.

"In terms of transmissibility, that has not changed, in terms of severity, that has not changed," Van Kerkhove told reporters.

It is not unusual for viruses to mutate and adapt as they spread, and the debate on Monday highlights how scientists are monitoring and tracking the new virus. The COVID-19 pandemic has so far killed more than 370,000 people and infected more than 6 million.

Martin Hibberd, a professor of emerging infectious disease at the London School of Hygiene & Tropical Medicine, said major studies looking at genetic changes in the SARS-CoV-2 virus that causes COVID-19 did not support the idea that it was becoming less potent, or weakening in any way.

"With data from more than 35,000 whole virus genomes, there is currently no evidence that there is any significant difference relating to severity," he said in an emailed comment.

Zangrillo, well known in Italy as the personal doctor of former Prime Minister Silvio Berlusconi, said his comments were backed up by a study conducted by a fellow scientist, Massimo Clementi, which Zangrillo said would be published next week.

Zangrillo told Reuters: "We have never said that the virus has changed, we said that the interaction between the virus and the host has definitely changed."

He said this could be due either to different characteristics of the virus, which he said they had not yet identified, or different characteristics in those infected.

The study by Clementi, who is director of the microbiology and virology laboratory of San Raffaele, compared virus samples from COVID-19 patients at the Milan-based hospital in March with samples from patients with the disease in May.

"The result was unambiguous: an extremely significant difference between the viral load of patients admitted in March compared to" those admitted last month, Zangrillo said.

Oscar MacLean, an expert at the University of Glasgow's Centre for Virus Research, said suggestions that the virus was weakening were "not supported by anything in the scientific literature and also seem fairly implausible on genetic grounds."

Mar 3: Just hours after the ending of a week-long “reduction” in violence that was crucial for Donald Trump’s peace deal in Afghanistan, the Taliban struck again: On Monday, they killed three people and injured about a dozen at a football match in Khost province. This resumption of violence will not surprise anyone actually invested in peace for that troubled country. The point of the U.S.-Taliban deal was never peace. It was to try and cover up an ignominious exit for the U.S., driven by an election-bound president who feels no responsibility toward that country or to the broader region.

Seen from South Asia, every point we know about in the agreement is a concession by Trump to the Taliban. Most importantly, it completes a long-term effort by the U.S. to delegitimize the elected government in Kabul — and, by extension, Afghanistan’s constitution. Afghanistan’s president is already balking at releasing 5,000 Taliban prisoners before intra-Afghan talks can begin — a provision that his government did not approve.

One particularly cringe-worthy aspect: The agreement refers to the Taliban throughout  as “the Islamic Emirate of Afghanistan that is not recognized by the United States as a state and is known as the Taliban.” This unwieldy nomenclature validates the Taliban’s claim to be a government equivalent to the one in Kabul, just not the one recognised at the moment by the U.S. When read together with the second part of the agreement, which binds the U.S. to not “intervene in [Afghanistan’s] domestic affairs,” the point is obvious: The Taliban is not interested in peace, but in ensuring that support for its rivals is forbidden, and its path to Kabul is cleared.

All that the U.S. has effectively gotten in return is the Taliban’s assurance that it will not allow the soil of Afghanistan to be used against the “U.S. and its allies.” True, the U.S. under Trump has shown a disturbing willingness to trust solemn assurances from autocrats; but its apparent belief in promises made by a murderous theocratic movement is even more ridiculous. Especially as the Taliban made much the same promise to an Assistant Secretary of State about Osama bin Laden while he was in the country plotting 9/11.

Nobody in the region is pleased with this agreement except for the Taliban and their backers in the Pakistani military. India has consistently held that the legitimate government in Kabul must be the basic anchor of any peace plan. Ordinary Afghans, unsurprisingly, long for peace — but they are, by all accounts, deeply skeptical about how this deal will get them there. The brave activists of the Afghan Women’s Network are worried that intra-Afghan talks will take place without adequate representation of the country’s women — who have, after all, the most to lose from a return to Taliban rule.

But the Pakistani military establishment is not hiding its glee. One retired general tweeted: “Big victory for Afghan Taliban as historic accord signed… Forced Americans to negotiate an accord from the position of parity. Setback for India.” Pakistan’s army, the Taliban’s biggest backer, longs to re-install a friendly Islamist regime in Kabul — and it has correctly estimated that, after being abandoned by Trump, the Afghan government will have sharply reduced bargaining power in any intra-Afghan peace talks. A deal with the Taliban that fails also to include its backers in the Pakistani military is meaningless.

India, meanwhile, will not see this deal as a positive for regional peace or its relationship with the U.S. It comes barely a week after Trump’s India visit, which made it painfully clear that shared strategic concerns are the only thing keeping the countries together. New Delhi remembers that India is not, on paper, a U.S. “ally.” In that respect, an intensification of terrorism targeting India, as happened the last time the U.S. withdrew from the region, would not even be a violation of Trump’s agreement. One possible outcome: Over time the government in New Delhi, which has resolutely sought to keep its ties with Kabul primarily political, may have to step up security cooperation. Nobody knows where that would lead.

The irresponsible concessions made by the U.S. in this agreement will likely disrupt South Asia for years to come, and endanger its own relationship with India going forward. But worst of all, this deal abandons those in Afghanistan who, under the shadow of war, tried to develop, for the first time, institutions that work for all Afghans. No amount of sanctimony about “ending America’s longest war” should obscure the danger and immorality of this sort of exit.

Washington, Feb 27: President Donald Trump has said that the US' relationship with India is "extraordinary" right now and a lot of progress was made in bilateral ties during his maiden official visit to the country where America will be doing a lot of business.

Talking to reporters, after his return from India on Wednesday, Trump said, "He (Prime Minister Narendra Modi) is a great gentleman, a great leader. It's an incredible country."

President Trump visited India from February 24 to 25. He was accompanied by first lady Melania Trump, daughter Ivanka Trump, son-in-law Jared Kushner and the top brass of his administration, including national security advisor Robert O'Brien.

They visited Ahmedabad, Agra and New Delhi before leaving for Washington on Tuesday.

During his stay, he addressed a massive rally in Ahmedabad, visited Agra and held official meetings in New Delhi.

The US President was feted at the world's largest cricket stadium in the "Namaste Trump" event in Ahmedabad and was cheered by tens of thousands of people.

"We were treated very, very well and we really enjoyed it. A lot of tremendous progress was made in terms of relationship - our relationship with India is extraordinary right now," he said.

"We are going to be doing a lot of business with India, they are sending billions and billions of dollars now to the United States," Trump said in response to a question.

In a tweet, his daughter Ivanka said that, Trump announced that US international development finance corporation "will establish a permanent presence in India to strengthen our economic ties, improve development plus further women's economic empowerment through WGDP (Women's Global Development and Prosperity Initiative)!"

On her arrival from India, she thanked PM Modi for "your warm hospitality as we visited your beautiful country and celebrated the strength, spirit and unity of the US and India!"

"Throughout our visit we saw monumental achievements of human creativity and proof of the infinite capacity of the human heart!" she said.

The first lady tweeted two pictures of her with Trump facing the Taj Mahal in Agra.

"One of the Seven Wonders of the World, the breathtaking Taj Mahal!" she said.

President Trump "reaffirmed the strong strategic partnership, vibrant economic ties and expanding security relationship between our two countries. Wonderful trip, but glad to be home! Thank you India!" said White House press secretary Stephanie Grisham.

During the visit, India and the US on Tuesday finalised defence deals worth $3 billion under which 30 military helicopters will be procured from two American defence majors for Indian armed forces.

The deals will include procurement of 24 MH-60 Romeo helicopters by India from the US at a cost of $2.6 billion. Another contract to acquire six AH-64E Apache helicopters for $800 million from the US is also on the table.
