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.
This from University of Cincinnati:
The researchers have since developed a breakthrough synergistic technology that uses anaerobic digestion to turn nutrient-rich organic materials into fuel (biogas), fertilizer, or soil conditioner, while using the carbon dioxide fraction of the biogas to grow algae. Simultaneously, lipid oils in the algae are also extracted and converted to biodiesel.
Their novel development allows the researchers to almost completely utilize the carbon found in food waste in a renewable manner.
