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.

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.

Singapore, Jul 11: Singapore Prime Minister Lee Hsien Loong has secured a “clear mandate” with his ruling People’s Action Party (PAP) winning 83 of the 93 contested parliamentary seats in the general election held amidst the Covid-19 pandemic, with the Opposition gaining ground by winning a record 10 seats.

The ruling party, in power since independence in 1965, secured 61.24 percent of the total votes cast in the election, down from 69.9 percent in 2015. About 2.6 million Singaporeans voted on Friday.

“We have a clear mandate, but the percentage of the popular vote is not as high as I had hoped for,” 68-year old Lee told a PAP’s post-results press conference on Saturday morning.

The opposition Workers’ Party secured 10 seats and defeated a team in the Group Representation Constituency of Sengkang led by former Minister in the Prime Minister’s Office Ng Chee Meng who is also the Secretary-General of the power National Trades Union Congress (NTUC).

The Prime Minister assured it is “only right” that Workers’ Party’s Indian-origin secretary-general Pritam Singh be “formally designated” as the Leader of the Opposition, and that he will be provided with “appropriate staff support and resources to perform his duties”.

Lee took the results in “these circumstances” as an “endorsement” of the party’s policies and plans as he had called the elections amidst Covid-19 pandemic.

“We’ll take this forward and work with Singapore to realise those plans and solve the problems which we have,” Channel News Asia quoted the premier as saying.

Lee, who leads the PAP as secretary-general, said, “Singaporeans understand what’s at stake and why we must come together to uphold our national interests.”

He pledged to use this mandate “responsibly” to deal with the Covid-19 situation and economic downturn, to take Singapore “safely through the crisis and beyond”.

“The results reflect the pain and uncertainty that Singaporeans feel in this crisis, the loss of income, the anxiety about jobs, the disruption caused by the circuit breaker and the safe distancing restrictions,” he said.

This was not a “feel-good” election, said Lee, Singapore’s third prime minister who faces the city state’s worst recession with the economy projected to shrink between 7 and 4 per cent.

Lee acknowledged that the result also showed a “clear desire” for a diversity of voices in Parliament.

“Singaporeans want the PAP to form the government, but they, and especially the younger voters, also want to see more opposition presence in parliament,” he noted.

Lee added that he looks forward to the participation and contribution of the Opposition in parliament.

Singh, whose Workers’ Party team retained Aljunied Group Representation Constituency (GRC), will have 10 elected MPs now, up from six previously. His fellow member also retained the Hougang single-member constituency seat.

“Whether it works out… and whether it’s seen as a strengthening of Singapore will depend not only on what the PAP does but also on what the Opposition does because the Opposition now has 10 MPs elected from constituencies,” said Lee.

He assured that the ruling party will listen to Singaporeans and do its best to address their concerns, and “try to win” their support, whether or not they voted for the PAP.

When asked by the media if the party had lost the youth vote, he noted that different generations have different life experiences, and the young have significantly different life aspirations and priorities compared to the older generations.

“That’ll have to be reflected in our political process and in the government’s policies because, in the end, the government’s policies must be to achieve the aspirations of every generation of Singaporeans,” Lee said, assuring Singaporeans.

He hoped that the new generations of Singaporeans “look critically, but with an open mind” at what previous generations have done, “examine what’s relevant and what continues to make sense to them in a new environment” and “learn from these experiences hard-won by their parents and grandparents”.

This is so that they do not have to “learn them all over again and pay a high price which has already been paid”.

Lee added that he was, naturally, disappointed at the loss of the newly formed Sengkang GRC, which the Workers’ Party won with 52.13 percent of the valid votes.

“Ng Chee Meng and his team -- Lam Pin Min, Amrin Amin and Raymond Lye -- always knew it was going to be a tough fight,” he said.

“They gave it their all, but Sengkang voters have spoken, and we respect their decision.”

Lee described it as a “major loss to my team” and to the fourth-generation leaders, especially as Ng is the secretary-general of the Labour Movement, the NTUC.

Singh, 43, told a press conference following the results that his team would “continue to endeavour for good outcomes on the ground” and to represent voters “faithfully in parliament”.

“Today’s results are positive, but we have to hit the ground running. We should not get over our head with the results. There’s much work to do. And I can assure you this Workers’ Party team is committed to serve Singapore,” he stressed.

The PAP contested all 93 seats and the Workers’ Party 21 seats. Nine other political parties also contested the elections.

A total of 192 candidates contested for seats through 17 Group Representation Constituencies (GRCs).

Seoul, Apr 26: A train presumed to belong to North Korean's Kim Jong-un has been spotted at a station in the state's eastern coastal town of Wonsan amid speculation about the leader's health, a US monitor said on Sunday, citing commercial satellite imagery on the region, Yonhap news agency reported.

According to 38 North-- a website devoted to analysis about North Korea, the imagery showed a train "probably belonging to Kim Jong Un parked at the Leadership Railway Station servicing his Wonsan compound since at least April 21."

"The approximately 250-metre long train, although partially covered by the station's roof, can be seen at a railway station reserved for use by the Kim family. It was not present on April 15 but was present on both April 21 and 23," it said.

"The train's presence does not prove the whereabouts of the North Korean leader or indicate anything about his health, but it does lend weight to reports that Kim is staying at an elite area on the country's eastern coast," it added.

The report came as rumours about his health have spread as Kim apparently skipped an important annual visit to the Kumsusan Palace of the Sun on the occasion of the April 15 birthday of late state founder and his grandfather, Kim Il-sung.

CNN intensified the speculation by reporting earlier last week that the United States is looking into intelligence that Kim is "in grave danger" after surgery.

Seoul officials have disputed recent media reports about Kim, saying there have been no unusual signs from the North. Some said that Kim is presumed to be staying in Wonsan for unspecified reasons.

Washington has also dismissed the reports, with US President Donald Trump calling such reports "incorrect" in a press briefing late last week.

On Saturday, other media reports stated that China has dispatched a team of medical doctors and officials to North Korea "to advise on" Kim, citing multiple unnamed people familiar with the situation.

North Korea's state media, however, has not made any mention of Kim's public activity for two weeks since he was last seen in April 11 presiding over a major party meeting, though it has reported on his handling of routine state affairs, such as sending diplomatic letters.
But not all speculation has proven to be false.

When he was absent from public for about a month in 2014, speculation arose about his health and a political crisis in the secretive state. He later reemerged with a cane and a limp reportedly after having a cyst removed from his ankle.

The 36-year-old leader is known to have various health problems apparently caused by obesity and heavy smoking. He took office as leader of the communist state after his father, Kim Jong-il, died of a heart attack in late 2011.
