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.

Tokyo, Jul 27: Gold hit an all-time high on Monday as tit-for-tat consulate closures in China and the United States rattled investors, boosting the allure of safe-haven assets, although sentiment was mixed with tech gains supporting some Asian stocks.

MSCI's ex-Japan Asia-Pacific index rose 1.3 percent as Taiwan's TSMC, Asia's third-largest company by market capitalisation, rose almost 10 percent.

The chipmaker's gains boosted other tech stocks in the region and came after rival Intel signalled it may give up manufacturing its own components due to delays in new 7-nanometer chip technology.

Also soothing sentiment, Chinese shares eked out gains after big falls late last week, with CSI300 index rising 0.5 percent.

S&P500 futures were last up 0.4 percent in choppy trade while Japan's Nikkei fell 0.5 percent, resuming trade after a long weekend and catching up with falls in global shares late last week.

Global shares had lost steam last week after Washington ordered China's consulate in Houston to close, prompting Beijing to react in kind by closing the US consulate in Chengdu.

US Secretary of State Mike Pompeo took fresh aim at China last week, saying Washington and its allies must use "more creative and assertive ways" to press the Chinese Communist Party to change its ways.

"US President (Donald) Trump used to say China's President Xi Jinping is a great leader. But now Pompeo's wording is becoming so aggressive that markets are starting to worry about further escalation," said Norihiro Fujito, chief investment strategist at Mitsubishi Securities.

Gold rose 1.0 percent to a record high of $1,920.9 per ounce, surpassing a peak touched in September 2011, as Sino-US tensions boosted the allure of safe-haven assets, especially those not tied to any specific country.

The yellow metal is also helped by aggressive monetary easing adopted by many central banks around the world since the pandemic plunged the global economy into a recession.

Some investors fret such an unprecedented level of money-printing could eventually lead to inflation.

MORE STIMULUS

Hopes of a quick US economic recovery are fading as coronavirus infections showed few signs of slowing.

That means the economy could capitulate without fresh support from the government, with some of earlier steps such as enhanced jobless benefits due to expire this month.

Investors hope US Congress will agree on a deal before its summer recess but there are some sticking points including the size of the stimulus and enhanced unemployment benefits.

US Treasury Secretary Steve Mnuchin said the package will contain extended unemployment benefits with 70 percent "wage replacement".

Democrats, who control the House of Representatives, want enhanced benefits of $600 per week to be extended and look to much bigger stimulus compared with the Republicans' $1 trillion plan.

Investors are looking to corporate earnings from around the world for hints on the pace of recovery in the global economy.

"It looks like rising coronavirus cases are starting to slow down recovery in many countries," said Masahiro Ichikawa, senior strategist at Sumitomo Mitsui DS Asset Management.

Concerns about the US economic outlook started to weigh on the dollar, reversing its inverse correlation with the economic well-being over the past few months.

The dollar index dropped 0.3 percent to its lowest level in nearly two years.

The euro gained 0.3 percent to $1.1693, hitting a 22-month high of $1.16590 as sentiment on the common currency improved after European leaders reached a deal on a recovery fund in a major step towards more fiscal co-operation.

Against the yen, the dollar slipped 0.5 percent to 105.605 yen, a four-month low while the British pound hit a 4 1/2-month high of $1.2832.

Oil prices dipped on worries about the worsening Sino-US relations.

Brent futures fell 0.46 percent to $43.14 per barrel while US crude futures lost 0.44 percent to $41.11.

Beijing, Mar 21: China reported no domestically transmitted coronavirus cases for the third consecutive day even as seven more fatalities have been confirmed, taking the death toll in the country to 3255.

No new domestically transmitted cases of COVID-19 were reported on the Chinese mainland for the third day in a row on Friday, China's National Health Commission (NHC) said on Saturday.

The overall confirmed cases on the mainland had reached 81,008 by the end of Friday, which included 3,255 who died, 6,013 patients still undergoing treatment, 71,740 patients who had been discharged after recovery, the NHC said.

Beijing, Jan 25: The death toll due to the novel coronavirus (2019-nCoV) outbreak in China has soared to 41, while the number of infected persons were 1,287, the National Health Commission said on Saturday.

The Commission said that 444 fresh cases were reported since Friday, with 237 patients in serious conditions, while 38 had been cured and discharged from hospitals, reports Efe news.

Health authorities have carried out check-ups on 15,197 people who have come into close contact with the infected persons. Nearly 14,000 of them continue to be monitored for symptoms.

The others cases outside of China were reported in France (two), Australia (one), Thailand (four including two cured), Japan (two including one cured), South Korea (two), the US (two), Vietnam (two), Singapore (three), Nepal (one), Hong Kong (five), Macao (two) and Taiwan (three).

The symptoms of the new coronavirus, provisionally designated by the World Health Organization as 2019-nCoV, are similar to those of cold but may be accompanied by fever and fatigue, dry cough and dyspnea (shortness of breath).

The WHO has so far to declared the outbreak as an international health emergency.

Strict measures were being carried out in China, which include complete suspension of transport in around a dozen cities in Hubei province and also cancelling Chinese New Year celebrations.

Traditional events at Lama Temple and Ditan Park in Beijing were cancelled due to the risk of spreading the virus, authorities reported Friday, while the famous Forbidden City has also been closed indefinitely.

Wuhan, the capital of Hubei, where the virus was first reported, has been on lockdown since Thursday to prevent further spread of the virus and the city's authorities have begun to build a "special hospital" with 1,000 beds for infected patients.

"Construction of the special hospital with a capacity of 1,000 beds for patients with #nCoV2019 has begun in Wuhan," official China Daily said on Twitter.

The hospital in Wuhan will be based on the model of a similar facility that was built in just seven days in Beijing to deal with SARS in 2003.
