Raise cockroaches to deal with kitchen waste?

A man in Shandong became a billionaire by raising mantises, and was called "Mr. Mantis". Because of raising mantises, the government often subsidizes him. Why is that?

As for raising mantises as a profession, it is probably something that most people would never think of. Because they have no idea what mantises can be used for. If someone wants to get rich by raising mantises, it is simply a fantasy.

How did Mr. Mantis come up with the idea of ​​raising mantises? It turned out that this was not a sudden idea. He became interested in mantises after watching a movie with his family. He found that mantises were not useless. So he began to study how to raise mantises and how to develop the mantis industry.

At first, it was just a small-scale breeding at home. The family members were obviously very disgusted, fearing that the mantis would bring pollution to their home. However, through breeding, this brother found something very interesting: the kitchen waste in his home was eaten and decomposed very efficiently by mantises.

He thought, if we use mantises to eat the kitchen waste of various restaurants, wouldn't it bring great environmental value? So he rented a site and started to breed mantises on a large scale to digest the kitchen waste. As the scale of breeding expanded, the kitchen waste of major restaurants in the surrounding area was recycled and digested by him, and the restaurants were relieved. He also found free food for the mantises. It seems that the breeding prospect is promising.

The local government heard that he was breeding mantises, specializing in handling the kitchen waste that restaurants could not handle, and thought that this was also a new way to protect the environment, so they strongly supported him in breeding mantises. Although the digestion of kitchen waste cannot generate much profit, it has solved a big problem in solving the pollution problem. The government subsidized his breeding business and encouraged him to continue to develop the mantis breeding industry. As the scale of breeding expanded, he discovered another headache, that is, mantises are easy to escape, and once they escape, they will affect the surrounding environment and ecology.

The quick-witted Mr. Mantis came up with a good idea. He dug a ditch around the farm and put fish fry in the ditch. Any mantis that dared to "jump into the river" to escape would be immediately eaten by the fish in the river.

Although Zhang Lang can eliminate kitchen waste, Mr. Zhang Lang always feels that other products need to be developed from Zhang Lang to make it more perfect.

In this way, Mr. Zhanglang's zhang crotch breeding industry chain has become more and more complete, from eliminating kitchen waste, starting with environmental protection to developing animal protein products, and then to developing organic fertilizer products. Each product is a profit point for breeding zhang crotches.
