This is the latest endeavor by industrial food researchers in Italy, Belgium, and elsewhere, who are right now developing novel methods to turn meat industry leftovers into protein-rich powders and slurry for the factory food industry.

As disgusting as it sounds, unused muscle tissue, tendons, bones, and other animal byproducts are loaded with proteins and fats that typically end up in landfills. According to FoodProcessing.com, up to 50 percent of the animal weight processed by the meat industry is composted, discarded, or incinerated. But modern science is hoping to basically recycle this waste and turn it back into food.
