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.

Saint Martin's Island, Feb 12: At least 15 women and children drowned and more than 50 others were missing after a boat overloaded with Rohingya refugees sank off southern Bangladesh as it tried to reach Malaysia Tuesday, officials said.

Some 138 people -- mainly women and children -- were packed on a trawler barely 13 metres (40 feet) long, trying to cross the Bay of Bengal, a coast guard spokesman told news agency.

"It sank because of overloading. The boat was meant to carry maximum 50 people. The boat was also loaded with some cargo," another coast guard spokesman, Hamidul Islam, added.

Nearly one million Rohingya live in squalid camps near Bangladesh's border with Myanmar, many fleeing the neighbouring country after a 2017 brutal military crackdown.

With few opportunities for jobs and education in the camps, thousands have tried to reach other countries like Malaysia and Thailand by attempting the hazardous 2,000-kilometre journey.

In the latest incident, 71 people have been rescued including 46 women. Among the dead, 11 were women and the rest children.

Anwara Begum said two of her sons, aged six and seven, drowned in the tragedy.

"We were four of us in the boat... Another child (son, aged 10) is very sick," the 40-year-old told news agency.

Fishermen tipped off the coast guard after they saw survivors swimming and crying for help in the sea.

The boat's keel hit undersea coral in shallow water off Saint Martin's Island, Bangladesh's southernmost territory, before it sank, survivors said.

"We swam in the sea before boats came and rescued us," said survivor Mohammad Hossain, 20.

Coast guard commander Sohel Rana said three survivors, including a Bangladeshi, were detained over human trafficking allegations.

An estimated 25,000 Rohingya left Bangladesh and Myanmar on boats in 2015 trying to get to Thailand, Malaysia and Indonesia. Hundreds drowned when overloaded boats sank.

Begum said her family paid a Bangladeshi trafficker $450 per head to be taken to Malaysia.

"We're first taken to a hill where we stayed for five days. Then they used three small trawlers to take us to a large trawler, which sank," she said.

Shakirul Islam, a migration expert whose group works with Rohingya to raise awareness against trafficking, said desperation in the camps was making refugees want to leave.

"It was a tragedy waiting to happen," he said.

"They just want to get out, and fall victim to traffickers who are very active in the camps."

Islam said in the past two months dozens of Rohingya reported approaches from traffickers to his OKUP migration rights group.

"Human smuggling and trafficking in the Bay of Bengal is particularly difficult to address as it requires concerted effort from multiple states," the Bangladesh head of UN agency the International Organization for Migration, Giorgi Gigauri, told news agency.

"The gaps in coordination are easily exploited by criminal networks."

Since last year, Bangladeshi authorities have picked up over 500 Rohingya from rickety fishing trawlers or coastal villages as they waited to board boats.

Trafficking often increases during the November-March period when the sea is safest for the small trawlers used by traffickers.

Bangladesh and Myanmar signed a repatriation deal to send back some Rohingya to their homeland, but none have agreed to return because of safety fears.

The charity Save the Children called on Myanmar to "take all necessary steps to ensure the Rohingya community can return to their homes in a safe and dignified manner".

"The tragic drowning of women and children... should be a wake-up call for us all," the group's Athena Rayburn said in a statement.

London, Apr 30: The coronavirus is roiling global job markets, but the picture is not all gloomy. Finance, technology and consumer goods firms are hiring tens of thousands in the United States and other countries, according to data from Microsoft Corp's professional networking site LinkedIn.

Across seven countries in North America, Europe and Asia, healthcare providers are among the busiest recruiters given the ongoing battle against the novel coronavirus, which has killed over 200,000 people and infected over 3 million people worldwide, LinkedIn said. But lifestyle changes during lockdown are also driving demand for financial consultants, factory workers, animators and game designers, and delivery workers.

Overall, the hiring rate has plunged in the first quarter from the year-ago period, and in late April remains lower than a year ago across most countries surveyed by the platform. But the data offer a glimmer of hope with a gradual uptick in China, where the coronavirus emerged last year and which leads the world in surfacing from a months-long lockdown.

LinkedIn, with over 690 million users worldwide, counts new hires when people add a new employer to their profile. The rate is the number of new hires divided by the total number of LinkedIn members in a country.

The figures, tracked since mid-February, are not corroborated by official jobs data and do not represent the actual number of jobs in an economy. Government figures are usually released with a time-lag of several weeks.

"We are confident that our data is directionally correct in that there has been a huge decline in hiring in the U.S. and abroad," Guy Berger, principal economist at LinkedIn in California, told Reuters.

Hiring in China plummeted 50% during the height of its coronavirus crisis in mid-February from 12 months earlier. Since restrictions were eased in early April, the hiring rate has inched up, and for the week ending April 24 was 3% lower than the same period in 2019.

Hiring in the United States, United Kingdom, France and Italy - which lead the world in coronavirus-related deaths - remains hugely depressed, but is falling less rapidly than a few weeks ago as the countries pass the peak of their epidemics.

Retailers including Walmart Inc, Amazon.com Inc and Instacart have said they would hire a total of over 700,000 workers to meet a surge in demand for groceries and household essentials during the coronavirus outbreak.

Coronavirus state-wise India update: Total number of confirmed cases, deaths on April 30

Consumer goods manufacturers such as Unilever, whose products include soap and shampoo, confirmed on Wednesday it was hiring to fill 300 jobs globally, but declined to elaborate.

Nestle told Reuters it was looking to fill 5,000 full-time U.S. positions in "a variety of levels across corporate and frontline."

Fidelity Investments, a Boston-based financial services firm, said it had accelerated recruitment because of the pandemic and was looking to fill at least 2,000 full-time roles for financial consultants, software engineers and customer service staff in the United States in 2020.

Companies hiring in the United States and other countries also include Apple Inc; ByteDance, the Chinese parent of video-sharing social network TikTok; Takeda Pharmaceutical Co Ltd; and aerospace and defence company Lockheed Martin Corp. These companies did not immediately respond to requests for comment.

DIRE WARNINGS

The International Labour Organization warned on Wednesday that 1.6 billion workers, or nearly half of the global workforce, especially in the informal economy, could lose their livelihoods.

Record numbers of people have applied for U.S. jobless benefits since mid-March, and the unemployment rate is expected to soar to 16%, White House economic adviser Kevin Hasset said this week, from a 50-year low of 3.5% before the pandemic hit.

Both Italy and France, in lockdown for nearly two months, have seen hiring rates drop by around 70% from a year ago, according to LinkedIn.

Since China is ahead of other countries on the pandemic timeline, improvements there could suggest the same is in store elsewhere, Berger said. Several American states and European countries have begun allowing some non-essential businesses and schools to reopen in the hopes of restarting the economy and allowing a gradual return to normal life.

"It's still slightly early to call it a firm recovery," Berger said, referring to improving prospects in China. "We're not expecting a full recovery but rather it's an indication that parts of the economy will switch on as lockdowns are eased, at least relative to the worst point of the pandemic."

New Delhi, Jan 8: Iran will welcome any peace initiative by India for de-escalating its tensions with the US after the killing of Iranian military commander Qasem Soleimani, the Iranian envoy here said on Wednesday.

His comments come hours after Iran launched missile strikes against two US military bases in Iraq in retaliation to the killing of its top commander General Qassem Soleimani.

"India usually plays a very good role in (maintaining) peace in the world. At the same time, India belongs to this region. We welcome all initiatives from all countries, especially India as a good friend for us, to not allow escalation (of tensions)," Iranian Ambassador to India Ali Chegeni told reporters after a condolence meeting for Solemani at the country's embassy here.

"We are not for war, we are looking for peace and prosperity for everybody in this region. We welcome any Indian initiative or any project that can help peace and prosperity in this world," he said.

On the Iranian attack on US targets in Iraq, Chegeni said his country retaliated under its right to defend.

Amid spiralling US-Iran tensions over the killing of Soleimani, External Affairs Minister S Jaishankar on Sunday had a conversation with his Iranian counterpart Javad Zarif and US Secretary of State Mike Pompeo, voicing India's concerns over the escalation of tensions.
