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.

Rome, Mar 11: Italy has recorded its deadliest day of the coronavirus crisis despite locking down the entire country, as New York deployed the National Guard to contain a disease that has sown worldwide panic.

The hardest-hit country in Europe said its death toll from the COVID-19 virus had risen Tuesday by a third to 631, with the surging epidemic taking its toll on global sporting, cultural and political events.

While authorities in China, where the outbreak began, have declared it "basically curbed", cases are multiplying around the world, sparking panic buying in shops, and wild swings on financial markets.

China remains the hardest-hit overall with more than 80,000 cases and over 3,000 deaths, out of a global total of 117,339 cases and 4,251 deaths across 107 countries and territories, according to an AFP tally.

The virus is infecting all walks of life, including politics, with US Democratic presidential hopefuls Bernie Sanders and Joe Biden both cancelling campaign rallies and British health minister Nadine Dorries saying she had tested positive.

And amid criticism of the US authorities' response, New York deployed the National Guard for the first time during the crisis to help contain the spread of the disease from an infection-hit suburb.

There have been 173 confirmed cases in New York state, including 108 in Westchester County, home to New Rochelle where the majority of infections have been detected.

"It is a dramatic action, but it is the largest cluster in the country. This is literally a matter of life and death," said state governor Andrew Cuomo.

"People are scared, it's an unusual situation to be in," Miles Goldberg, who runs a New Rochelle bar, told AFP.

"It makes people nervous to be around others, it makes people nervous to get inside into businesses and such," he said.

In an unprecedented move, Italian Prime Minister Giuseppe Conte has told the 60 million residents of his country they should travel only for the most urgent work or health reasons.

And while squares in Milan and Rome were emptied of their usual bustle and traffic, some residents appeared uncertain if they were even allowed to leave their homes for everyday tasks like shopping.

The virus has battered tourism around the world, as people scrap travel plans, and a restaurant owner in Florence in northern Italy said that the impact on business had been catastrophic.

"We hope that we will see the end of it, because from around 140 covers a day, this afternoon, we've gone down to 20-25," Agostino Ferrara told AFP.

Pope Francis also seemed to muddy the waters, holding a mass in which he urged priests to go out and visit the sick -- something Conte has specifically discouraged.

Sporting events continued to fall victim to the virus as authorities urge people to avoid large gatherings.

Arsenal's game at Manchester City was postponed after players from the London club were put into quarantine, making it the first Premier League fixture to be called off because of the virus.

The virus has sparked doubts about the Olympics due to open in Tokyo on July 24 and the traditional flame lighting ceremony in Greece is set to be held without spectators.

In the United States, organisers rescheduled the two-week Coachella music festival for October.

The virus and the response to the crisis has prompted pandemonium on global markets with volatility not seen since the world financial crisis in 2008.

After suffering its worst session in more than 11 years at the beginning of the week, the Dow Jones Index in New York bounced back significantly, rising five percent on Tuesday.

Politicians around the world have scrambled to put together emergency packages to ease the significant financial hardships the virus is expected to cause for households and businesses.

US President Donald Trump, who is relying on a strong economy to boost his re-election hopes, promised to announce "major" economic measures on Tuesday.

The biggest item on his wish list is a cut in payroll taxes. But even allies in Congress and reportedly some aides in the White House are sceptical, questioning the cost.

Italy prepared Tuesday to let families skip mortgage and some tax payments while Japan unveiled a second emergency package to tackle economic woes stemming from the outbreak, including $15 billion in loan programmes to support small businesses.

Analysts warned of further volatility ahead however.

"It's like winding up a rubber band. The more you wind it, when you let go, the more it pops," said LBBW's Karl Haeling.

"A lot of the uncertainty goes to the root of the virus itself."

San Francisco, Mar 14: Microsoft on friday announced that co-founder Bill Gates has left its board of directors to devote more time to philanthropy.

The 64-year-old stopped being involved in day-to-day operations at the firm more than a decade ago, turning his attention to the foundation he launched with his wife, Melinda.

Gates served as chairman of Microsoft's board of directors until early in 2014 and has now stepped away entirely, according to the Redmond-based technology giant.

“It's been a tremendous honor and privilege to have worked with and learned from Bill over the years,” Microsoft chief executive and company veteran Satya Nadella said in a release.

Nadella said Microsoft would continue to benefit from Gates' “technical passion and advice” in his continuing role as a technical advisor.
“I am grateful for Bill's friendship and look forward to continuing to work alongside him,” he added.

Gates left his CEO position in 2000, handing the company reins to Steve Ballmer to devote more time to his charitable foundation.

He gave up the role of chairman at the same time Nadella became Microsoft's third CEO in 2014.

Regularly listed among the world's richest people, William H. Gates was a geeky-looking young man when he and Paul Allen co-founded Microsoft in 1975.

Gates went on to turn his attention from software to fighting disease and other humanitarian challenges with his wife, under the auspices of the Bill and Melinda Gates Foundation.

Washington, Jun 12: US President Donald Trump is considering suspending a number of employment visas including the H-1B, most sought-after among Indian IT professionals, in view of the massive unemployment in America due to the coronavirus pandemic, according to a media report.

The proposed suspension could extend into the government’s new fiscal year beginning October 1, when many new visas are issued, The Wall Street Journal reported on Thursday, quoting unnamed administration officials.

“That could bar any new H-1B holder outside the country from coming to work until the suspension is lifted, though visa holders already in the country are unlikely to be affected,” the daily reported.

H-1B is the most coveted foreign work visas for technology professionals from India.

Such a decision by the Trump administration is likely to have an adverse impact on thousands of Indian IT professionals. Already a large number of Indians on the H-1B visas have lost their jobs and are headed back home during the coronavirus pandemic.

The White House, however, said that no final decision has been made and the administration is considering various proposals.

“The administration is currently evaluating a wide range of options, formulated by career experts, to protect American workers and job seekers especially disadvantaged and underserved citizens — but no decisions of any kind have been made,” White House spokesman Hogan Gidley said in a statement.

In addition to the H-1B visas, the suspension could apply to the H-2B visa for short-term seasonal workers, the J-1 visa for short-term workers including camp counselors and au pairs and the L-1 visa for internal company transfers, the financial daily reported.

Meanwhile, the US Chambers of Commerce CEO Thomas Donohue on Thursday wrote a letter to Trump, expressing concern over his reported move on temporary work visas.

“As the economy rebounds, American businesses will need assurances that they can meet all their workforce needs. To that end, it is crucial that they have access to talent both domestically and from around the world,” Donohue wrote in a letter to Trump.

According to The Hill newspaper, Donohue said that American businesses need L-1 visa holders, who have a work visa valid for a relatively short amount of time, for necessary expertise.

He noted the importance of H-1B visa holders, who have a work visa valid for multiple years, for various industries, including technology, accounting and manufacturers, the newspaper said.

“Policies that would, for example, impose wide-ranging bans on the entry of nonimmigrant workers or impose burdensome new regulatory requirements on businesses that employ foreign nationals would undermine that access to talent and in the process, undercut our economy’s ability to grow and create jobs,” Donohue added.
