However, the hero of today's article, he is not only not afraid of cockroaches, but also keeps cockroaches, not only raising cockroaches, but also raising 800 million cockroaches at a time! With such a huge number, does he want to learn from Li Shizhen and take cockroaches as medicine, otherwise cockroaches can still get gold? Li actually didn't think of this at first. When he came up with the answer to this question, he became the owner of more than 800 million cockroaches.
▲ Li and his cockroaches.

Li lives in Zhangqiu District, Jinan. He is over 500 years old. He worked in many industries, civil servants, scientific research and the boss of pharmaceutical companies in the first half of his life. In the summer of 2008, Li saw her daughter watching an American cartoon online. The protagonist of this cartoon is a cockroach.
In China, many people call cockroaches oil thieves. My daughter and Li have learned a lot about cockroaches. Li feels very fresh. It turns out that cockroaches are treasures and can even be used as raw materials for medicinal materials. But at that time, Li did not think that he would raise a large number of cockroaches one day.

Things just passed. One day three years later, when Li was eating in the company canteen, he heard the staff complain that the slops in the canteen cost hundreds of dollars every day, so he had to find someone to carry them away. It is no longer allowed to raise pigs with swill because it will cause the risk of homologous pollution. At this time, Li once again remembered the oil thief, that is, the cockroach. He went home to discuss with his wife, bought a goldfish bowl and put it in the bathroom, and began the experiment of raising cockroaches. Li fed these cockroaches all kinds of food, ate eight Chinese cuisines, adapted well and propagated quickly. With the breeding of cockroaches, the odor in the bathroom is also "breeding".

So, Li moved his cockroach breeding experiment to the mountain. During this time, he calmed down and learned a lot about cockroach breeding and industrialization research. Li also went to other cockroach breeding bases in Shandong Province for investigation. Time flies. By the end of 20 15, Li felt that the time was ripe, so he resolutely quit his high-paying job and started a "cockroach factory" with a few friends.

Dealing with kitchen waste is the most basic utilization function of Li to raise cockroaches. Kitchen waste is very difficult to treat, and it can neither be burned nor pollute the land and groundwater when it is buried. Therefore, Zhangqiu Environmental Sanitation Center is very happy that Li's cockroaches can solve this problem, so they collect and transport raw materials for Li for free. 20 16, the kitchen waste treatment center in Zhangqiu District of Jinan City was established.
The center soon got on the right track, every feeding and production link was automated, and the breeding speed of cockroaches was getting faster and faster. By 20 18, this cockroach factory can eat 50 tons of kitchen waste every day. So far, Li's cockroach factory has achieved great success. However, there are too many cockroaches here, and the locals are very worried. What if they run away?

Of course, we will not ignore the problem of Li. He built the cockroach factory as solid as gold and even had a "moat"! He built a protective wall with a cement wall, and specially set up two barriers: the water curtain on the wall of the factory building can wash cockroaches into the pool and be eaten by fish; Outside the factory building, there is an 85 cm wide ditch-if cockroaches run out and fall into the ditch, they will also be eaten by fish.
The government will subsidize cockroach factories. The more garbage they dispose of, the greater the subsidy. And in this factory, there is a complete industrial chain around cockroaches. Cockroaches are rich in protein. In the breeding base, old cockroaches and dead cockroaches will fall into the tank, be collected, disinfected and sterilized, then dried and crushed into protein feed. Tested by relevant departments, the protein content of this protein feed exceeds many animal protein feed additives on the market, and the market price of one ton is about 10,000 yuan. So Li not only cooperated with the local feed factory, but also set up a chicken farm himself.

The excrement of cockroaches is also used as organic fertilizer, and the bio-heat generated by cockroaches is used for greenhouse cultivation. Cockroach factory, cockroaches are raised below, and vegetables and flowers are planted above. Moreover, we mentioned in the introduction that cockroaches can also be used as medicine, and cockroaches are among the ingredients of the new rehabilitation liquid that everyone is very familiar with.

Li's cockroach factory can now bring him hundreds of millions of income every year. Last year, two new factories were completed. The number of cockroaches in Li is about to reach 4 billion, and the kitchen waste in Jinan will also be treated here. How to deal with kitchen waste quickly and massively has become Li's next goal.
