"Teaching assistant, you go on, and then what? Are you squeezing toothpaste with me? You know I'm in a hurry! ”

"It's still landfill-based, those heavy and worthless, and easy-to-stick glass bottles, don't please scavengers, unless they are special, they won't be picked out! After the solid waste treatment plant is pulled down, there will be some waste pickers who are stationed near the landfill, and will carry out secondary waste pickup on all kinds of garbage that are pulled from all over the city and dumped here every day. They prefer plastic that can be sold for money over glass! ”

"Teaching assistant, I would like to conclude that the glass bottles, which are no longer favored by waste collection, are mostly picked up by waste pickers after being thrown into the trash can, and the rest are dug and buried in landfills! Right? ”

"Classmate, it seems that your comprehension ability is not bad, that's what you mean! Those waste pickers who are dragging their families and staying in the landfill, when they pick up waste, they actually complete the landfill work of solid waste landfill, which is garbage classification. One of the reasons why there are very few garbage incineration plants in Lunhong City is that the garbage classification is not in place, and the incineration plant has higher requirements for solid waste classification. ”

The TA was right!

These waste pickers, who have really been and will be an indispensable part of our solid waste treatment for a long time in the future, are the ones who have alleviated the problem of our daily inattention to garbage classification to a certain extent!

They have always paid for our faults.

"Teaching assistant, you always say scavengers, do you know each other? Can you find him? ”

At this moment, when the teaching assistant didn't know how to answer, the teacher picked up my question again!

On the surface, it should have been a hot conversation between me and the teaching assistant, but he was very embarrassed on the sidelines, and he didn't go in, and he didn't continue to be here!

But actually, I guess it might be a mystery!

"From an economic point of view, the behavior of ordinary people is still affected by the economy. Now as a raw material back to the kiln, the cost of broken glass is about 600 yuan/ton. If there is only one glass bottle, it is estimated that it will be recycled, which is certainly not economically viable. Unless it is in bulk, such as beer bottles, it is recycled to the distillery in batches, cleaned and then filled. But you said that it is a glass bottle thrown into the trash, so I can tell you with certainty that it is impossible to reuse it when the labor is so high and the price of recycled broken glass is so low! ”

It turned out that the teacher wanted to end the topic that the teaching assistant and I were chatting about seriously!

I used what I had learned to talk back!

"However, in terms of process theory, glass bottles can be recycled, then returned to the kiln and melted again, and shaped!"

"But in general, it takes more than 1,000 degrees for glass to melt into a liquid state. On the kiln, the maximum temperature is more than 1500 degrees. However, the recycled broken glass, and then returned to the kiln, must also be consistent with the composition of the liquid glass in the kiln, and the composition in each factory is slightly different, especially the composition of different glass is huge, such as the composition of bottles and home window glass, which is very different. Therefore, the probability of recycling is very small. It can be considered that it is impossible to recycle and reuse! ”

"What do you mean by that? Why do you know so much about this? Are you an economics major? ”

I questioned Mr. You, as if he was pouring a basin of cold water on my head from top to bottom, cold and cold!

Because after he finished speaking, I was even more confused, and I didn't know where to look!

"Nothing, I'm just a fashion design teacher! I'm not an economics major, but I just know a little bit about it! I'm really half a bottle of water, I hope I won't laugh at it! ”

The teacher seems to know a lot, which is really not like Deng Deng at all!

"Then what school did you graduate from, and what major?"

"I studied environmental engineering at a university in another province! At present, most of the situation in Lunhong City is that all recyclable and non-recyclable garbage is collected at the garbage transfer station without sorting, and then sent to landfills or garbage incineration sites after being packed and compressed. One of the assignments of our professional internship was to visit a waste treatment plant, and I don't want to go there a second time in my life! ”

"Where are you visiting the garbage treatment plant?"

"I returned to the province from other provinces for the summer vacation, and my homework was to visit there, so I had no choice but to choose the nearest Lunhong City Garbage Treatment Plant!"

"Do you know where it is?"

Who knows, the teaching assistant actually talked to the teacher about this problem, and I didn't even know where to insert it!

I can't help but wonder who they really are!

"Teacher, I understand what you said, Lunhong City currently has different colored garbage cans in each district, but in the old community, sanitation workers only open one garbage can at a time, and close and open the other when one is full. There are also new communities that can abide by the principle of garbage classification, so strict that the bags filled with garbage are also thrown into recyclable bins, but I think these ends of the garbage that are strictly sorted at the source may still meet, and it is still difficult to change this phenomenon! ”

At this moment, I can understand a little bit that I used to discuss a problem with some students with similar grades to me, and it turned out that the classmates around me were so disgusted, especially when they left others aside and didn't ask!

"Teaching assistant, although this is the case, we may not be able to change the status quo of Lunhong City, which has imperfect garbage classification, but we can start with some small things, and wrap those broken glass slags, used razors, and other sharp or poisonous things tightly. If the scavengers don't pay attention to it, they will be pricked by sharp things, so dirty garbage dumps, with wounds, in order to live can not stop scavenging, there are no sanitary conditions, they are really super easy to inflammation, infection and illness. Besides, there are many children playing there, and their nature makes them want to put everything in their mouths, and if they don't pay attention, the consequences will be even more serious! ”

"Teacher, do you think that wrapping the garbage that may cause harm to people can greatly alleviate this situation?"

In fact, when the teacher discussed with the teaching assistant, he thought that he was not so sissy, and he should be talking about very serious issues, and he was not so casual!

This is also different from Deng Deng, no matter what Deng Deng talks about, he has always been a virtuous person who has no integrity!

But I couldn't take it anymore and yelled!

"You two are endless, don't you both say you don't know? As a result, you can say so much, you can't be annoyed! Am I here listening to your academic discussions, or am I going to answer a debate paper? ”

Unbeknownst to me, the teaching assistant and the teacher looked at me in unison, and then, as if nothing had happened, they started talking again!

"How can I say it, teaching assistant, let me tell you this, in fact, the severity of the smog can be seen, and there are actually a lot of environmental problems that we need to solve in places that we can't see. Don't let the air pollution you get from breathing blindfold us to water pollution and solid waste pollution! ”

"But, teacher, then the question is, how to ensure the classification of garbage at the source? Separating at source can certainly guarantee independent processing, e.g. for plastic reuse. In some places, the discarding of beverage bottles is divided into caps, bottles and labels. And we in Lunhong City, now we can't guarantee that we can be so meticulous from the source, so can we ensure that the sorting is complete through technical means?

"Teaching assistant, I can tell you responsibly, as far as I know, I don't think I can do it!"

"Do you still take me seriously? You're just trying to blast me away, aren't you? No wonder you have so few people in this fashion design training class, I think it is more appropriate for you to see a scrap shop, to tell you, I am also a scholar, I am not afraid, if you have the ability, we will fight! ”

The way the teacher looked at me was exactly the same as the scumbag, it seemed that he didn't believe me!

The teaching assistant is even more excessive, and now he doesn't even stare at me anymore, and he seems to be really dedicated!

It's as if the two of them are solving a big problem in the world that is plaguing humanity!

"So what do we do? Teacher again? ”

"Teaching assistant, in fact, there is a very simple thing to do is that when throwing garbage, you can not tie the mouth of the garbage bag, so as to ensure that they are scattered in the subsequent treatment, rather than a whole, because some bags are really strong, especially many people throw melon seed shells in plastic bottles, really big husband? In addition, try not to mix a lot of water in the garbage, the taste of landfill leachate is really not good to ask, and the degree of trouble to dispose of is unimaginable! ”

I've finally found something I'm interested in!

"Wait a minute! You just said, try not to mix a lot of water in the garbage, the taste of landfill leachate is really not good, and the degree of trouble to deal with is unimaginable, right? ”

"Zhan Ye, I didn't take a good professional class back then, and I don't remember many details such as the so-called particle size range. Maybe the answer is also very far from the question, don't blame it! So, I changed careers and devoted myself to the fashion design industry! ”

"But you know, I'm not listening to your history of struggle!"

I figured it out!

That is, the water in the trash can was deliberately poured into it, and it was poured in by the person who threw the bottle!

But why did that man do that?

What the hell is that pile of iron in that bottle?

Why did Wu Shuai find it all of a sudden, and he wanted to take it very much, and he wanted to stop talking!

What is there in the water that will make Wu Shuai faint in a short time?

If it was conductive, it was unlikely, and my little cousin and I didn't receive any damage to our bodies at all!

Oops!

Wu Shuai's arm is in unbearable pain!

If he drives, will he ......

I quickly picked up the phone and dialed my little cousin's number, but the voice was "I'm sorry, the phone you dialed is off!" ”
