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.

Kuala Lumpur, Jul 28: Malaysia's ex-leader Najib Razak was found guilty Tuesday in his first trial over the multi-billion-dollar 1MDB scandal, two years after the fraud contributed to the downfall of his long-ruling government.

The former prime minister could now face decades in jail after being convicted on all charges in the case related to the looting of sovereign wealth fund 1Malaysia Development Berhad.

Billions of dollars were stolen from the investment vehicle and spent on everything from high-end real estate to pricey art, while investment bank Goldman Sachs also became embroiled in the scandal.

Anger at the looting played a large part in the shock loss of Najib's long-ruling coalition in elections in 2018, and he was arrested and hit with dozens of charges following his defeat.

The verdict was a test of Malaysia's rule of law. It comes about five months after Najib's scandal-plagued party returned to power as part of a coalition, development observers had feared could affect the outcome of the case.

About 16 months after it began, the Kuala Lumpur High Court delivered the verdict in Najib's first trial, which centred on the transfer of 42 million ringgit ($9.9 million) from a former 1MDB unit, SRC International, into his accounts.

Najib had vehemently denied wrongdoing.

But Judge Mohamad Nazlan Mohamad Ghazali took apart all the arguments put forward by his defence, and found him guilty on the seven charges he faced.

"In conclusion, after considering all the evidence in this trial, I find the prosecution has successfully proven the case," the judge told the court.

The charges were one of abuse of power, three of criminal breach of trust and three of money-laundering.

The counts of abuse of power and criminal breach of trust are punishable by up to 20 years in jail each, while the money-laundering charges are punishable by up to 15 years each.

Sentencing was not handed down straight away. The 67-year-old will likely appeal and he may not be sent to jail immediately. If his conviction is upheld, he will also be barred from political office for several years.

Najib had insisted he was ignorant of the transactions.

The defence team portrayed Najib as a victim and instead sought to paint financier Low Taek Jho, a key figure in the scandal who has been charged in the US and Malaysia, as the mastermind.

Low, whose whereabouts are unknown, maintains his innocence.

Prosecutors insisted Najib was in control of the 1MDB unit, SRC International.

The return of Najib's party to power as part of a coalition in March followed the collapse of Mahathir Mohamad's reformist administration.

Since then, 1MDB-linked charges were unexpectedly dropped against the ex-leader's stepson Riza Aziz, a producer of Hollywood movie "The Wolf of Wall Street", in exchange for him agreeing to return assets to Malaysia.

Prosecutors also dropped dozens of charges against Najib ally Musa Aman, the former leader of Sabah state.

The amounts involved in Najib's first case are small compared to those in his second and most significant trial, which centres on allegations he illicitly obtained more than $500 million.

Malaysia had charged Goldman Sachs and some current and former staff, claiming large amounts were stolen when the bank arranged bond issues for 1MDB.

But the two sides agreed to a $3.9 billion settlement last week in exchange for charges being dropped.

Manila, Mar 16: The Philippines has detected an outbreak of avian flu in a northern province after tests showed presence of the highly infectious H5N6 subtype of the influenza A virus in a quail farm, the country's farm minister said on Monday.

Agriculture Secretary William Dar said the bird flu virus, the same strain that hit some local poultry farms in 2017, was detected in Jaen municipality in Nueva Ecija province, where about 1,500 quails had died on one farm alone.

A total of 12,000 quails have been destroyed and buried to prevent further infections, Dar said, citing field reports.

"We are on top of the situation," he said. "Surveillance around the 1-km and 7-km radius will be carried out immediately to ensure that the disease has not progressed around the said perimeter."

Animal quarantine checkpoints have also been set up to restrict the movement of all live domestic birds to and from the quarantine area, he said.

"We would like to emphasise that this is a single case affecting one quail farm only," Dar said.

Dr. Arlene Vytiaco, technical spokeswoman for avian flu at the agriculture department, said that while there is a possibility of transmission to humans through excretion and secretion, "the chances are very slim".

"There is also zero mortality rate," she said.

Dar said his department and the local government were jointly conducting an investigation and contact-tracing to determine the source of infection.

To ensure steady domestic supply of poultry, he said the transport of day-old chicks, hatching eggs and chicken meat will be allowed provided the source farms have tested negative for bird flu.

Sydney, Jul 28: Nearly 3 billion koalas, kangaroos and other native Australian animals were killed or displaced by bushfires in 2019 and 2020, a study by the World Wide Fund for Nature (WWF) said on Tuesday, triple the group's earlier estimates.

Some 143 million mammals, 2.46 billion reptiles, 180 million birds and 51 million frogs were impacted by the country's worst bushfires in decades, the WWF said.

When the fires were still blazing, the WWF estimated the number of affected animals at 1.25 billion. The fires destroyed more than 11 million hectares (37 million acres) across the Australian southeast, equal to about half the area of the United Kingdom.

"This ranks as one of the worst wildlife disasters in modern history," said WWF-Australia Chief Executive Officer Dermot O'Gorman in a statement.

The project leader Lily Van Eeden, from the University of Sydney, said the research was the first continent-wide analysis of animals impacted by the bushfires, and "other nations can build upon this research to improve understanding of bushfire impacts everywhere".

The total number included animals which were displaced because of destroyed habitats and now faced lack of food and shelter or the prospect of moving to habitat that was already occupied.

The main reason for raising the number of animal casualties was that researchers had now assessed the total affected area, rather than focusing on the most affected states, they said.

After years of drought made the Australian bush unusually dry, the country battled one of its worst bushfire seasons ever from September 2019 to March 2020, resulting in 34 human deaths and nearly 3,000 homes lost.
