The United States is wasting food at an alarming rate. According to the Food and Agriculture Organization of the United States, the country wastes 40 percent of all food produced—amounting to 1.3 billion tons of food waste produced.

But extra garbage and financial strain are not the only things food waste produces, it also generates a huge amount of greenhouse gas during decomposition. More specifically, global food waste creates 3.3 billion tons of greenhouse gas annually.

Those numbers were especially alarming to researchers from the University of Cincinnati College of Engineering and Applied Science, who proposed a way to transform food waste into bioenergy back in 2013. That proposal has just been accepted.

The OmniProcessor is the ultimate example of that old expression: one man’s trash is another man’s treasure.

The Bill & Melinda Gates Foundation is working to turn poop into drinking water with this ingenious new machine.

As part of their effort to improve sanitation in poor countries, the Gates Foundation has helped give flight to an OmniProcessor that burns human waste to produce water and electricity.

How does it work? Check out the video to see the process.

But here’s the big question – why do we need to turn waste into drinking water and electricity?

Here at ECS, we love to talk about renewable resources – and we also like talking about poop. And with Britain’s first ‘poo-powered’ bus hitting the roads, we have a perfect excuse to talk about both.

GENeco has developed the new 40-seat Bio-Bus, which is powered by human waste. In technical terms, the bus runs on the biomethane gas that is produced at a sewage treatment works in Avonmouth.

According to BBC, the bus can travel up to 300 km – or 186 miles – on one tank of gas. One tank would be equivalent to the annual waste of five people. Further, the vehicle will emit up to 30 percent less carbon dioxide than conventional diesel vehicles.

The lack of adequate sanitation facilities accounts for 4,100 preventable deaths every day.

With our Energy and Water Summit right around the corner, we’ve only got one thing on our mind: poop.

Forty percent of the world’s population – 2.5 billion people – practice open defecation or lack adequate sanitation facilities, and the consequences can be devastating for human health as well as the environment.

The Electrochemical Society and the Bill & Melinda Gates Foundation know there is no easy solution to this problem, but we are dedicated to finding and funding innovative research to reinvent the sanitation infrastructure.

In Francis de los Reyes’ TEDTalk entitled, “Sanitation is a basic human right,” the environmental engineer and sanitation activist makes his case for the total reinvention of the sanitation landscape as we know it.

“For the past 14-years, I’ve been teaching crap,” Reyes says.

And that he has. Reyes has dedicated his time to studying and researching human waste. The problem is especially relevant in India, where open deification is putting citizens at major health risks.

Less than a third of India’s 1.2 billion people have access to sanitation and more than 186,000 children under five die every year from diarrheal diseases caused by unsafe water and poor sanitation, according to the charity WaterAid.

The United Nations said in May half of India’s people defecate outside – putting people at risk of cholera, diarrhea, dysentery, hepatitis A and typhoid.

With India accounting for 818 million of the 2.5 billion people who lack adequate sanitation, most of the country’s rivers and lakes are polluted with sewage and industrial effluents.

So why can’t we just build western style flush-toilets in countries such as India?

“It’s just not possible,” Reyes says.

In these developing worlds, there is often time not enough water or energy to take on such a feat. Also, laying out sewer lines would cost governments tens of trillions of dollars.

Through our partnership with the Bill & Melinda Gates Foundation, we hope to help solve these issues.
