Bioreactor lays waste to China's pig poop problem

Unfortunately for the Chinese, their estimated 700 million hogs produce more dumps than dumplings. They output a nostril-clogging 1.5 million tons of stinky business, an amount which is fast becoming an ecological and public health scourge. In response, Australian company CRC Care has developed a "PoopCare bioreactor," which converts the waste into energy and fertilizer. One already in use in central China cost $36,400 and will recoup $52 worth of fertilizer per pig per year. So, for China's impoverished farmers, that's more money in the bank -- and less pig sh*t under the fingernails.
