Tang Yan inevitably turned on the computer excitedly and checked the data given by the garbage dump.

At this glance, I was suddenly surprised and couldn't close my mouth.

This... This......

The cost of disposing of plastic waste is too low, isn't it?

Because of the different scale of the equipment, it is about 200~300 per ton.

This cost can be deducted from the cost of fuel, and the cost of three generations of plastics can save at least 5,000 yuan per ton.

It's a huge profit!

But how can the cost of disposing of plastic waste be so low?

Tang Yan read the report given by the garbage dump carefully, and then he understood.

The cost given by the garbage dump is only calculated for fuel and labor, so the cost is very low.

But there are also costs for collecting plastic waste and burying incinerants.

There is no need to worry about the cost of burying incineration, because the three generations of plastic are burned more fully, and basically nothing is left, and the rest is just the doped pigment or inlaid things inside. The cost of landfilling is certainly lower than that of plastic.

What Tang Yan needs to worry about is only the cost of collection.

Although plastic waste will now also be collected and managed in a unified manner.

But the number of dumps is limited, and not all plastic waste is incinerated.

If the three generations of plastic waste are not incinerated and the current plastic waste is no different from the harm to the environment.

In general, plastic waste is mixed with other waste, and the dump cannot be incinerated at the disposal site.

If you talk about building a new garbage dump, the cost will be high.

At this stage, a more reliable method is to use manual or machine separation of plastic waste from other waste, and then incinerate the three generations of plastic waste.

In addition, there is also a cost issue that cannot be ignored, which is estimated to account for the majority.

That is, although the probability of recycling ordinary plastics at this stage is extremely low, there are still some that can be recycled.

However, the three generations of plastics cannot be recycled at all, and can only be incinerated and destroyed, which invisibly increases the cost.

It's time to start a new round of data collection.

In the data report sent by the garbage dump, Tang Yan found the phone number of the contact person and called the other party, asking about the daily workload and wages of the workers in charge of garbage classification, as well as the electricity bill of the conveyor belt.

According to the data of the other party, it can be calculated that the cost of sorting each ton of plastic is about 300.

Tang Yan breathed a sigh of relief, the cost is not high, and it is not a problem to create jobs.

Then there's the issue of recycling ordinary plastics.

The question is a bit more complicated.

Only about 30% of the world's plastic can be recycled.

However, it is very difficult to calculate how much it costs to turn the recycling process into a finished plastic.

Tang Yan couldn't figure it out.

Now it can only be assumed that at the extreme extreme, 30% of ordinary plastic can be recycled directly at no cost

That is equivalent to the raw material cost of ordinary plastics, which becomes about 70%.

Tang Yan simply calculated in his heart that the cost of raw materials for ordinary plastics would be reduced to about 10,000 per ton.

The extra incineration and manual sorting costs of the three generations of plastics are about five or six hundred yuan, and the cost of raw materials is 10,000 per ton, which is still feasible!

Tang Yan took the pen and paper, planed out the same items, and calculated the cost of each category of ordinary plastics, and calculated the cost of three generations of plastics.

As a result, Tang Yan's eyes lit up slightly.

In addition to the lowest cost of raw material polycarbonate profit margin is very low, the other has about 1,000 per ton, and even individual categories can reach more than 2,000 profit margins.

That's great!

Tang Yan clenched his fist vigorously.

This profit margin is enough to attract the current plastic manufacturers!

Although it is a big expense to change equipment in the early stage, it will definitely be profitable in the long run!

And there is Huade company to help promote, coupled with environmental protection issues, maybe the official notice can also help promote, sooner or later three generations of plastic will replace the current ordinary plastic.

This is a contribution to environmental protection!

Tang Yan was in a good mood and called Gao Jiang over, and the two officially devoted themselves to the research and development of three generations of plastics.

Gao Jiang didn't know whether Tang Yan was the second generation of power or had strong scientific research ability.

This official work is up, and I finally understand!

It's this kind of energy that doesn't sleep all night, and at first glance it's a scientific research dog!

However, within a few days, the research and development work was advancing rapidly, and the results were soon produced, and it has entered the final stage of test and commissioning.

Gao Jiang slowly turned his evaluation of Tang Yan's scientific research dog into a scientific research boss!

At the same time, his heart was excited.

I didn't expect to go to help the boss pick up someone, and I hugged a big thick leg!

Such a big project is about to come to fruition!

And as the only assistant, what if he can mix up the second work of the paper.

Although there is a high probability that it will not be mixed, as the only deputy of the entire project, it is also a great qualification.

As long as you rewrite a thesis based on the experience of the past few days, it is definitely enough for a graduation thesis!

Gao Jiang was in a high mood.

I slept less than 20 hours in 10 days, and in the last few days, I haven't slept all night.

Tang Yan, a landlord who ruthlessly oppressed coolies, was a little unbearable.

If Gao Jiang dies suddenly, she will lose a good assistant who is not afraid of hardship or tiredness.

No, the other person must be arranged to sleep.

Tang Yan used his identity as the team leader to ask Gao Jiang to go back to sleep.

Gao Jiang had two big dark circles under his eyes: "No! I'm not tired! ”

For this kind of disobedient, Tang Yan has a trick to deal with.

She clasped her hands to her chest and looked at Gao Jiang obliquely: "If you don't go back to sleep, the second work of the paper won't be you!" ”

"What... What the! Gao Jiang instantly reminded, "I... Can I really be a two-in-one!? ”

He said that Nice was the only assistant to the project. To put it mildly, it is just a machine that runs errands and collects information, and basically has no constructive effect.

This can even be used as a second work!?

Gao Jiang was almost crying.

Tang Yan looked at his watch: "If you can't sleep for 10 hours, the second work is not you." ”

So what are you hesitating about! Gao Jiang worked for several days in a row, his mind was not clear and he was very excited, and he rushed out stupidly with his books, shouting back while rushing back.

"I'm going to get 10 hours of sleep!"

Tang Yan shrugged.

Such a good coolie, it's okay to give a second job!

Besides, if you don't give Gao Jiang Erzuo, there will be no one else in their project.

When Gao Jiang slept enough and washed up, although he still had two big dark circles under his eyes, he returned to the laboratory in good spirits, and Tang Yan had already done the finishing work.

What surprised Gao Jiang the most was that he even finished writing his thesis!

He looked at the time displayed on his phone, no problem, he was gone for 15 hours, not 15 days.

It takes 15 hours to write a paper on such a big project!?

Gao Jiang deeply realized that the big guy in front of him was far from being understood by mortals like him!
