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.

United Nations, Apr 28: UN chief Antonio Guterres has warned that extremist groups are taking advantage of the COVID-19 lockdowns and intensifying efforts on social media to recruit youths online by exploiting their anger and despair, asserting that the world cannot afford a lost generation due to the unprecedented global health crisis.

The UN Secretary-General made the remarks on Monday during a video conference to review the five years since its adoption of a landmark resolution on youth, peace and security.

We can already see such groups taking advantage of the COVID-19 lockdowns, intensifying their efforts on social media to spread hatred and to recruit young people who may be spending more time at home and online, he said.

Guterres told the Security Council that even before the current crisis, young people were facing enormous challenges.

Listing startling numbers, he said one of every five young people was already not in education, training or employment and one of every four is affected by violence or conflict. Every year, 12 million girls become mothers while they themselves are still children.

These frustrations and, frankly, failures to address them by those in power today, fuel declining confidence in political establishments and institutions. And when such a cycle takes hold, it is all too easy for extremist groups to exploit the anger and despair, and the risk of radicalisation climbs, he said.

Issuing a call to action on youth, peace and security, Guterres said the world cannot afford a lost generation of youth, their lives set back by COVID-19 and their voices stifled by a lack of participation. Let us do far more to tap their talents as we tackle the pandemic and chart a recovery that leads to a more peaceful, sustainable and equitable future for all.

With over 1.54 billion children and youth out-of-school and young people acutely feeling the impact of the COVID-19 crisis, Guterres said countries must do more to harness the talents of young people to address the crisis and its aftermath.

In presenting his first report on the Security Council resolution, the UN chief said youth were already confronting numerous challenges even before the pandemic, including in accessing education, or through being affected by violence and conflict. Those pressing for peace or upholding human rights have been threatened.

Despite these obstacles, young people across the world have joined the common fight against the coronavirus disease, supporting both frontline workers and people in need. And they continue to push for change.

UN Youth Envoy Jayathma Wickramanayake spoke of the need for more meaningful partnerships between young people and the civil society organisations and government institutions that work on the youth, peace and security (YPS) agenda.

To date, there are no national action plans on YPS but I'm pleased to note that in some countries, these are in the process of development, she said.

For a national roadmap to be successful, a participatory, transparent and youth-led process with adequate resources are needed, she said.

Issuing his four-point call to action for the Council, Guterres urged members to do more to address the various challenges facing young people.

He also called for investment in youth participation, but also in their organisations and initiatives.

We must strengthen human rights protections and protect the civic space on which youth participation depends, he said. And fourth, we must emerge from the COVID-19 crisis with a determination to recover better - massively increasing our investment in young people's capacities as we deliver the Sustainable Development Goals.
