The theory provided by Su Yi comes from the life science laboratory of Harvard University, where the theory of garbage classification and treatment was proposed a few years ago.

The theory seems simple, but it is very cumbersome to operate.

Garbage is divided into two categories: organic and inorganic, organic waste is treated according to the stacking method, and inorganic waste is directly returned to nature after being cleaned up.

The organic waste biostacking method is based on the type of organic matter from small to large categories, and the use of the inclusion relationship is processed layer by layer.

There is such a process in this approach.

First of all, inorganic garbage such as stones, glass slags, cans, etc. can be stripped out first, and those that can be recycled are recycled, and those that cannot be recycled are thrown into landfills.

After treatment in this way, the remaining inorganic waste is treated in layers using biological, chemical and physical methods.

Different types of waste can be disposed of in different ways, for example, food waste can be biodegraded or degraded naturally after landfilling, while plastic waste can only be used in landfills.

The treatment of food waste is included in the treatment of plastic waste, as both can be landfilled.

In order to protect the environment to the greatest extent and prevent animals from swallowing plastic waste when looking for kitchen waste in landfills, Haval's laboratory will choose to use biodegradable methods to treat kitchen waste first, and the degraded kitchen waste will be used as organic fertilizer for crops, and finally the plastic waste will be left in landfill.

Without the temptation of kitchen waste, there will be very few animals that do not eat plastic waste.

This is just a simple theoretical description, and the actual types of garbage are much more than described, and the stacking method is much more complicated.

This kind of garbage disposal can indeed protect the environment to the greatest extent and maximize the recycling of resources, but this is based on the idealized model of the laboratory, and the cost of incomplete waste separation at the source is very high in the country.

Su Yi introduced this method and also completely got rid of the degradation and treatment methods of different garbage, some of which do belong to the blind spot of Xia Guo's scientific and technological knowledge, and have a good reference and reference role.

"Aren't you afraid that the Haval Lab will be held accountable?"

Jiangcheng University, Xiao Ming asked Su Yi.

"You also know that a lot of the settings in the lab are idealistic, and I just introduced this method and I hope that the students can use it as a reference. ”

The weather is getting colder, and Su Yi puts on a thick tweed coat, short hair and large-rimmed glasses to look delicate and elegant.

"The students were smart enough to combine the characteristics of the phagocytosis II colonies in such a short period of time to form a treatment. Su Yi added.

In the group paper handed in by the students, the way provided by Su Yi was optimized.

To put it simply, the organic matter is handed over to the phagocytosis II colony for processing, and the remaining inorganic matter after treatment is reclassified, and the recovered matter should be returned to nature.

This method is also very in line with the actual situation of garbage in Xia Kingdom, from the source of garbage classification, Xia people are not unable to do it, but need to cultivate habits, need legal and moral support, and most importantly, need time.

It took decades of sorting the garbage of the East to bear fruit, and it is obviously unscientific to expect Xia Guo, which has a population of 15 or 600 million, to do this well in just a few years.

Since people can't do it well for a while, then leave it to the microbes and the computer.

The computer team of the students used the quantum computer provided by Pangu Technology to make a detailed garbage type identification system, and used robots to replace manual garbage sorting.

Xiao Ming nodded with satisfaction, and said that this project was very simple, and this is the reason.

Phagocytosis II colonies, quantum chips, and the Pangea system are all tools, and students only need to use this tool.

The waste sorting and disposal process in the paper becomes simpler.

In the first step, all the garbage is mixed together. There's no hassle of source sorting and end sorting.

In the second step, all the garbage is thrown into a garbage disposal tank filled with phagocytosis II colonies.

The garbage disposal tank has a culture medium that phagocytosis II colonies like, and a temperature and pressure suitable for its growth.

Because the phagocytosis II colony has been modified, the plastic waste will also be dissolved at this time.

In this process, the phagocytosis II colony will dissolve all dissolved substances (mainly organic matter), and the heavy metal elements existing in the ionic state will enter the body of the phagocytosis II colony, and the heavy metals will accumulate in the corpse of the colony because they cannot participate in the formation and metabolism of the colony.

Finally, the corpses of the colonies are salvaged and disposed of centrally – either chemically extracted from the heavy metals (mainly copper and zinc), or individually landfilled in a single location with minimal environmental costs.

The third step is artificial intelligence garbage classification.

After the second step, the untreated waste is filtered out, which is mainly inorganic waste such as cans, waste glass, nails, etc.

The filtered waste is then transported to an open field to dry, where it is sorted by an AI robot.

What can be recycled is recycled, and what cannot be recycled is returned to nature.

What can be recycled is like cans, iron, etc., and what cannot be recycled, such as sediment, stones, etc., will be thrown into landfills for disposal.

In this way, Xia Guo can basically achieve perfection in garbage disposal.

"Wouldn't this be a waste of resources? For example, the organic matter that can be recovered will be dissolved by the phagocytosis II colony. "When discussing the paper with the students, many students asked this question.

The most important thing in garbage sorting is recycling.

There is no need for Xiao Ming to answer this question, the hard-working people of Xia have already given the answer.

Xiao Ming said: "Xia has a population of 15.6 billion, engaged in all walks of life, many of them are engaged in waste recycling, in garbage disposal, everything that can be recycled is actually recycled, and it is better than any country." Cans, plastic bottles, waste cardboard, waste glass, etc., the hard-working people of Xia have already completed this step. ”

Xiao Ming's words made many students nod their heads again and again.

Who said that the people of Xia Guo did not classify and recycle garbage, and most of the valuable ones that could be recycled were recycled.

And the cost and time savings of the treatment methods developed by the students are much higher than the value earned by traditional waste sorting and recycling.

Xiao Ming stood up and clapped his hands and said, "Attention to each group, now everyone has to divide labor and cooperate for the final sprint." I have provided the chip and the corresponding hardware equipment, the sorting robot should be developed, and the garbage disposal process should be optimized, and I will give you a week. I hope to see results in a week. ”

Xiao Ming also said: "In addition, I have set up a private entrepreneurship fund, if you can succeed, I will invest in us to make money together!"

The students cheered!

Xiao Ming didn't notice that at the door of the classroom, a graceful figure was leaning against the door.
