The domestic waste generated every year is about 300 million tons, and most of the municipal waste will be disposed of by landfill.

There are three types of landfill treatment, one is called simple landfill, which directly buries the matter without any other engineering measures. This method is simple and crude, and it treats the symptoms rather than the root cause, but because of its low cost, it is the most mainstream landfill method.

The better one is called controlled landfill, which has certain engineering measures and relatively little pollution to the natural environment, but is also relatively less implemented.

In some large cities, sanitary landfill treatment is adopted, that is, the landfill waste is isolated from the environmental system to the greatest extent through engineering measures, and it is basically harmless. However, due to the high cost, this method is mainly implemented in Beijing, Shanghai, Guangzhou and other places.

In addition to the most mainstream landfill treatment, a small part is incinerated and a very small part is composted.

The main problem with incineration is that the investment is huge, and an incineration power plant with a daily processing capacity of 1,000 tons will probably need more than 100 million yuan, and 100 million here refers to the US dollar......

In addition, the harmful gas "dioxin" produced by waste incineration is very toxic and has not been well solved.

In recent years, developed countries such as Europe and the United States have increasingly adopted composting methods to treat garbage, but in China, the development of composting treatment still needs to be improved.

Nanshui County's economy is relatively backward, there are more rural areas, more than a dozen townships, nearly 300 villages, most of the domestic garbage in these villages do not have complete collection and treatment measures.

According to rough estimates, these nearly 300 villages can produce about 200-300 tons of domestic garbage every day, which is nearly 100,000 tons a year.

If all this garbage can be handed over to Vientiane for disposal, tens of thousands of tons of garbage and fertilizer can be produced every year, and all of them can be sold, which will be at least 20 million yuan.

At this scale, it is estimated that a composting plant with a daily processing capacity of 500 tons is more than enough.

In addition to the composting plant, several small transfer stations will be built, at least 500 sanitation workers will be employed, dozens of garbage trucks, dozens of experienced veteran drivers, and composting plant employees......

Lin Lin finally came down, and if he wanted to put up the shelves of the composting plant, he would need to invest one or two million yuan anyway, which is not a small amount.

Lin Han, Song Shuqing, and Jiang Ruiyang discussed together for a long time, and finally decided to choose the address of the composting plant not far from Tianhu Village.

As long as you follow the main cement road in Tianhu Village, you can reach the composting plant directly without turning around, and there is a road nearby, the transportation is convenient, and the conditions in all aspects are quite good, and the plan was quickly decided.

After Tianhu Village became the first village in Nanshui, Song Shuqing was quite familiar with the officials of the county party committee and county government, and he immediately came forward and contacted some officials in the county to discuss the construction of the factory.

Song Shuqing relied on reading a lot, and he was very talkative, and he was a biological high-tech, on par with developed countries, and he was investing tens of millions of dollars, feeding back agriculture, etc., and it was also related to the transformation of the national industrial structure, the Belt and Road Initiative, and the Chinese dream.

In the end, Secretary Li became extremely enthusiastic and decided to bring a few people over in person.

In the end, the two parties agreed on a time to negotiate in a restaurant with a low consumption level.

At the dinner, everyone pushed cups and changed lamps.

After talking for a while, Secretary Li suddenly said, "Dr. Jiang Ruiyang is also from Peking University?"

Jiang Ruiyang smiled: "The Department of Biology of Peking University usually follows the tutor in the Institute of Microbiology. ”

Secretary Li asked again: "Who is your mentor?"

Professor Chen Zheyu. ”

Dong Xiao, deputy director of the Agriculture Bureau, couldn't help but be surprised: "Is it Professor Chen Zheyu, who was elected as a Changjiang Scholar at the age of 36? ”

Jiang Ruiyang said modestly: "I became Professor Chen's doctoral student mainly because of good luck. ”

"I can't say that, opportunities are reserved for those who are prepared, and Dr. Jiang must still have a lot of advantages. Secretary Li said.

Jiang Ruiyang was a little embarrassed: "Then I may be overweight." ”

Everyone couldn't help but laugh, and the atmosphere was lively.

"Boss Lin, what is the situation of the compost plant that Vientiane plans to build?" asked Director Zhou at this time.

Lin Han thought for a while: "This plan is mainly designed for the situation that there are many rural areas in Nanshui County. ”

"First, rural waste has a high organic content, which is suitable for composting, and the fertilizer produced can also be sold to farmers for agricultural production. ”

"Second, the garbage disposal mechanism in rural areas has not yet been established, and a large amount of garbage is littered and piled up, which needs to be treated urgently. ”

Dong Xiao lifted his glasses: "Boss Lin, I also know a certain amount about the composting plant." As far as I know, there seems to be some problems with the quality of the fertilizer produced by the composting plant......"

"Our composting plant, which is provided by Vientiane Laboratory and has the help of the Institute of Microbiology of Peking University, has a very high treatment efficiency, and the quality of the fertilizer can exceed that of most chemical fertilizers, and the price is relatively affordable. Lin Han explained.

Secretary Li was a little surprised: "Is the Institute of Microbiology of Peking University also involved?"

Jiang Ruiyang nodded: "Vientiane purchased advanced strains worth one million yuan from the Institute of Microbiology of Peking University, and I was recommended by my mentor. ”

Song Shuqing interjected with a smile: "This composting plant should be the only enterprise in Nanshui County that has cooperation with Peking University." ”

Vientiane Laboratory, Institute of Microbiology, Peking University...... This head, the feeling of being tall and tall, and several government officials couldn't help but show their intentions.

Director Zhou hurriedly asked, "Boss Lin, how much money do you plan to invest?"

"A conservative estimate, fifteen million dollars. ”

Lin Han said: "In addition, the fertilizer produced by the composting plant will be given priority to farmers in Tianhu Village. In this way, Tianhu Village will be able to produce more high-quality grain, and Vientiane Liquor will be able to develop faster. ”

Song Shuqing added: "Not long ago, the village committee of Tianhu Village has unanimously passed a resolution to provide a site for the expansion of the distillery, and the first phase of the distillery's expansion plan is about to begin. ”

Secretary Li couldn't help but say: "So, Vientiane Liquor and Vientiane Composting Plant complement each other?"

Lin Han nodded: "So to speak. Vientiane Waste Management Company is responsible for solving the problem of garbage in rural areas, and while solving the garbage problem, it will also benefit agricultural production activities and indirectly promote the development of the wine industry. ”

Song Shuqing has always had many views on the county's economic construction, and then said: "Nanshui County has many rural areas, and now it is not an advantage. As long as we do a good job in agriculture, manage the environment, and vigorously develop the wine industry, we can also develop the catering industry and tourism industry in the future......"

"In the future, we can even build Nanshui County into a national characteristic demonstration area!"
