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.

Washington, Mar 31: The United States has performed over one million coronavirus tests so far, said President Donald Trump on Monday.

"Today, we reached a historic milestone in our war against coronavirus. Over 1 million Americans have now been tested, more than any other country by far, not even close," Trump said during a press briefing.

US Health Secretary Alex Azar said that approximately 100,000 samples are tested for coronavirus daily.

The number of novel coronavirus (COVID-19) cases within the United States surpassed 150,000 and the death toll has reached 2828, according to Johns Hopkins University.

Mar 3: Just hours after the ending of a week-long “reduction” in violence that was crucial for Donald Trump’s peace deal in Afghanistan, the Taliban struck again: On Monday, they killed three people and injured about a dozen at a football match in Khost province. This resumption of violence will not surprise anyone actually invested in peace for that troubled country. The point of the U.S.-Taliban deal was never peace. It was to try and cover up an ignominious exit for the U.S., driven by an election-bound president who feels no responsibility toward that country or to the broader region.

Seen from South Asia, every point we know about in the agreement is a concession by Trump to the Taliban. Most importantly, it completes a long-term effort by the U.S. to delegitimize the elected government in Kabul — and, by extension, Afghanistan’s constitution. Afghanistan’s president is already balking at releasing 5,000 Taliban prisoners before intra-Afghan talks can begin — a provision that his government did not approve.

One particularly cringe-worthy aspect: The agreement refers to the Taliban throughout  as “the Islamic Emirate of Afghanistan that is not recognized by the United States as a state and is known as the Taliban.” This unwieldy nomenclature validates the Taliban’s claim to be a government equivalent to the one in Kabul, just not the one recognised at the moment by the U.S. When read together with the second part of the agreement, which binds the U.S. to not “intervene in [Afghanistan’s] domestic affairs,” the point is obvious: The Taliban is not interested in peace, but in ensuring that support for its rivals is forbidden, and its path to Kabul is cleared.

All that the U.S. has effectively gotten in return is the Taliban’s assurance that it will not allow the soil of Afghanistan to be used against the “U.S. and its allies.” True, the U.S. under Trump has shown a disturbing willingness to trust solemn assurances from autocrats; but its apparent belief in promises made by a murderous theocratic movement is even more ridiculous. Especially as the Taliban made much the same promise to an Assistant Secretary of State about Osama bin Laden while he was in the country plotting 9/11.

Nobody in the region is pleased with this agreement except for the Taliban and their backers in the Pakistani military. India has consistently held that the legitimate government in Kabul must be the basic anchor of any peace plan. Ordinary Afghans, unsurprisingly, long for peace — but they are, by all accounts, deeply skeptical about how this deal will get them there. The brave activists of the Afghan Women’s Network are worried that intra-Afghan talks will take place without adequate representation of the country’s women — who have, after all, the most to lose from a return to Taliban rule.

But the Pakistani military establishment is not hiding its glee. One retired general tweeted: “Big victory for Afghan Taliban as historic accord signed… Forced Americans to negotiate an accord from the position of parity. Setback for India.” Pakistan’s army, the Taliban’s biggest backer, longs to re-install a friendly Islamist regime in Kabul — and it has correctly estimated that, after being abandoned by Trump, the Afghan government will have sharply reduced bargaining power in any intra-Afghan peace talks. A deal with the Taliban that fails also to include its backers in the Pakistani military is meaningless.

India, meanwhile, will not see this deal as a positive for regional peace or its relationship with the U.S. It comes barely a week after Trump’s India visit, which made it painfully clear that shared strategic concerns are the only thing keeping the countries together. New Delhi remembers that India is not, on paper, a U.S. “ally.” In that respect, an intensification of terrorism targeting India, as happened the last time the U.S. withdrew from the region, would not even be a violation of Trump’s agreement. One possible outcome: Over time the government in New Delhi, which has resolutely sought to keep its ties with Kabul primarily political, may have to step up security cooperation. Nobody knows where that would lead.

The irresponsible concessions made by the U.S. in this agreement will likely disrupt South Asia for years to come, and endanger its own relationship with India going forward. But worst of all, this deal abandons those in Afghanistan who, under the shadow of war, tried to develop, for the first time, institutions that work for all Afghans. No amount of sanctimony about “ending America’s longest war” should obscure the danger and immorality of this sort of exit.
