Waste disposal solutions ?How about an army of cockroaches that eats them?

Space for waste disposal is a growing concern of modern times.  But Mr Li Tanong farm in Zhangqiu district in Jinan, in China’s Henan province has 300 million american cockroaches that can swallow about 15 tonnes of organic waste daily. That is about one fourth of all the districts kitchen scraps. American cockroaches aren’t new to china though,it was often used as an ingredient in traditional medicine. They also have many cockroach farms, the biggest one situated in Xichang , southwestern province, where annually six billion adult cockroaches are produced.

China’s mostly gets its disposal done via fermentation, a costly and not so environment friendly solution. It’s annual generation of 60 million tonnes of kitchen waste is a headache for the authorities of the asian giant. Mr Li said that the cockroach system let’s him dispose wastes in a non-polluting way. The farm owner already owns 300 tonnes of cockroaches and is gearing up for an expansion to take the tally to a staggering 4000 tonnes ! If done, this will help them process about 200 tonnes of food waste from Zhangqiu and neighbouring cities on a daily basis. He said that the cockroaches aren’t afraid of anything and can take in any thing of any taste. 

In a report submitted to Beijing early this year, about 28000 full sized coakroaches per square foot were produced in Xichang in a year. The american cockroach is one among the world’s biggest cockroach. It lives for roughly two years and is 4 cm.
