Turning Kung Pao Chicken into organic fertilizer

By on 2012-02-18 12:33:12 in Agriculture, Forestry & Food,

Gaoancun food waste processing plant at Beijing produces 400 tons of fertilizer per day, using food waste discarded from restaurants and canteens across the city. Half-eaten cabbage, decomposing Kung Pao Chicken, and other food waste are sorted where non-organic waste is filtered out. The remaining waste is poured into vats heated at 80 degrees Celsius, where it mixes with a specially manufactured enzyme. Ten hours later, the waste emerges as a powdery brown coloured fertilizer, which the plant’s designers say is ideal for growing organic fruit and vegetables.

The Gaoancun plant has been built by Goldenway Biotech. The company sells its waste generated fertilizer to organic farms. Goldenway has opened eight similar plants across China. The company’s secret is its garbage eating enzyme, developed in a lab in the Southern Chinese city of Chengdu. The garbage takes 10 hours to decompose into fertilizer. - read more
