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.

Paris, Aug 5: French President Emmanuel Macron on Tuesday said France will deploy a civil security detachment and several tonnes of medical equipment to Lebanon, whose capital was hit by an explosion that left over 70 people dead and thousands injured.

"Emergency doctors will also reach Beirut as soon as possible to strengthen hospitals. France is already engaged," the French President said in a tweet.

US Secretary of State Mike Pompeo, also extended his deepest condolences to all those affected by the "massive explosion at the port of Beirut."

"We are closely monitoring and stand ready to assist the people of Lebanon as they recover from this tragedy. Our team in Beirut has reported to me the extensive damage to a city and a people that I hold dear, an additional challenge in a time of already deep crisis. 

We understand that the Government of Lebanon continues to investigate its cause and look forward to the outcome of those efforts," he said in a statement.

UK Prime Minister Boris Johnson said his country is ready to provide support in any way it can.

"The pictures and videos from Beirut tonight are shocking. All of my thoughts and prayers are with those caught up in this terrible incident. The UK is ready to provide support in any way we can, including to those British nationals affected," Johnson said.

Israeli people share the pain of their Lebanese neighbours after a devastating blast in the port of Beirut and reach out to offer their aid, Israeli President Reuven Rivlin said on Tuesday.

"We share the pain of the Lebanese people and sincerely reach out to offer our aid at this difficult time," Rivlin said on Twitter.

Over 70 people have been killed while thousands of others were wounded in the massive explosion on Tuesday in Beirut which shattered buildings and caused widespread damage.

Jun 9: The World Health Organization says it still believes the spread of the coronavirus from people without symptoms is “rare,” despite warnings from numerous experts worldwide that such transmission is more frequent and likely explains why the pandemic has been so hard to contain.

Maria Van Kerkhove, WHO''s technical lead on COVID-19 said at a press briefing on Monday that many countries are reporting cases of spread from people who are asymptomatic, or those with no clinical symptoms.

But when questioned in more detail about these cases, Van Kerkhove said many of them turn out to have mild disease, or unusual symptoms.

Although health officials in countries including Britain, the U.S. and elsewhere have warned that COVID-19 is spreading from people without symptoms, WHO has maintained that this type of spread is not a driver of the pandemic and is probably accounts for about 6 per cent of spread, at most.

Numerous studies have suggested that the virus is spreading from people without symptoms, but many of those are either anecdotal reports or based on modeling.

Van Kerkhove said that based on data from countries, when people with no symptoms of COVID-19 are tracked over a long period to see if they spread the disease, there are very few cases of spread.

“We are constantly looking at this data and we''re trying to get more information from countries to truly answer this question,” she said. “It still appears to be rare that asymptomatic individuals actually transmit onward.”

Islamabad, Feb 17: Prime Minister Imran Khan on Monday warned that Pakistan may face another refugee crisis if the international community failed to take notice of the current situation in India.

Speaking at the two-day refugee summit in Islamabad on 40 years of hosting Afghan refugees in Pakistan, he said India’s "ultranationalist ideology going unchecked could lead to destruction and the region could become a flashpoint", The Express Tribune quoted him as saying.

Khan said if the international community does not take notice of this situation, it will create another refugee crisis for Pakistan as Muslims of India will move to Pakistan.

"This is not the India of Jawaharlal Nehru and Mahatma Gandhi. The United Nations (UN) must play its role otherwise it will become a very big problem in the future," Duniya News quoted Khan as saying.

He said said that Prime Minister Narendra Modi’s statement that India can destroy Pakistan in 11 days is not a responsible statement by a premier of a nuclear state with a huge population, the paper reported.

Khan made the statement in the presence of visiting UN Secretary General Antonio Guterres, who was also attending the summit.

He said because of the "Hindutva" ideology, Kashmiris have been lockdown for over 200 days. He alleged under the same ideology, the BJP-led government passed two discriminatory nationalistic legislations, targeting 200 million Muslims in India.

Khan was referring to India's Citizenship (Amendment) Act and the revocation of the special status to Jammu and Kashmir.

The new citizenship law passed by the Indian Parliament in December 2019 offers citizenship to non-Muslim persecuted religious minorities from Pakistan, Bangladesh and Afghanistan.

The Indian government has maintained that the CAA is an internal matter of the country and stressed that the goal is to protect the oppressed minorities of neighbouring countries.

India revoked Jammu and Kashmir's special status on August 5. Reacting to India's move, Pakistan downgraded diplomatic ties with New Delhi and expelled the Indian High Commissioner.

India has always maintained that Jammu and Kashmir is its integral part and ruled out any third party mediation, including either from the UN or the US, saying it is a bilateral issue with Pakistan.
