Chapter 278： The problem of polylactic acid and lactide

"I'm the President of the University ( Find the latest chapter!

"Plastic restriction order?" A question mark appeared on Chen Hao's head, and his brows were slightly wrinkled, "Isn't this thing mentioned a long time ago?"

In his memory, this thing seems to have been proposed a long time ago, how to say it will be implemented after New Year's Day next year.

However, the success rate was only 25%, which gave him some headaches.

However, the problem of success rate may be the problem of existing team ability.

"I raised this thing very early." Chen Chong nodded, and then explained to Chen Hao, "As early as January 2008, the General Office of the State Council issued the "Notice on Restricting the Production and Sales of Plastic Shopping Bags" , which was implemented in June of that year, but the effect was limited.

But this time is different. This time, nine departments including the National Development and Reform Commission, the Ministry of Ecology and Environment, and the Ministry of Industry and Information Technology jointly issued the "Notice on Solidly Promoting Plastic Pollution Control". This time the country is serious. "

"Is it very strict?" Chen Hao really didn't pay attention to this, after all, he has been out of the country for eight years.

"Pretty strict!"

Chen Chong looked serious, "This "Notice" stipulates that starting from January next year, the production and sale of disposable plastic cotton swabs and disposable foam plastic tableware will be banned nationwide; the national catering industry will ban the use of non-degradable disposable plastic straws."

After hearing what Chen Chong said, Chen Hao also realized that the country was serious this time. But it seems that there are a lot of new regulations to be implemented in January next year? In addition to this plastic restriction order, the Civil Code, the "divorce cooling-off period", and the purchase tax exemption for new energy vehicles will all be officially implemented.

But what does this plastic restriction order have to do with schools?

"Since the plastic restriction order is going to be implemented, there should be alternative environmentally friendly materials, right?" Chen Hao expressed his doubts.

There is not much money to be made on this environmentally friendly material.

Chen Hao felt that there was no need to focus on this, and it was better to study some advanced technologies.

Seeing the headmaster's contempt, Chen Chong smiled bitterly and asked a question that Chen Hao didn't expect.

"Principal, you should have had milk tea, right?"

"Drinked it." There are quite a lot of milk tea brands in Ludao, whether it is a chain brand milk tea or some internet celebrity milk tea.

By the way, how is he now?

Because of the milk tea, Chen Hao suddenly thought of Lao He. In bringing down Tianma Electronics Li Zhiguo, Lao He contributed a lot.

In a flash, it has been almost four months since I returned to Ludao from the beautiful country.

Chen Hao looked a little dazed. These four months were neither long nor short.

"Principal? Are you alright?" Chen Chong looked at Chen Hao in a daze and was at a loss for a moment. Could the milk tea remind the principal of something so sad?

"I'm fine, you continue to say what happened to the milk tea." said Chen Hao, who had recovered.

Although he didn't understand what the principal was thinking just now, Chen Chong didn't feel anything about it, and continued on the previous topic: "This time the enhanced plastic restriction order will be most affected by the food and beverage industry, especially the milk tea industry, which will be greatly affected. Impact!"

"Very big impact? Is it on the straw? I don't remember that there are paper straws that can be used instead?" Chen Hao remembered that straws are not just plastic straws, but also paper straws.

A few days ago, I went to Starbucks to drink a Frappuccino, and I used a paper straw.

Chen Chong shook his head and said, "Paper straws are very inconvenient to use. The best degradable material to replace plastic straws is straws."

"Straw? Polylactic acid?" Although Chen Hao studied a computer, there is still a knowledge base stored in his brain.

Polylactic acid, also known as polylactide, is a polyester polymer obtained by polymerizing lactic acid as the main raw material. It is a new type of biodegradable material.

"Yes, it's polylactic acid."

Chen Chong explained: "There are many problems with paper straws. They are easy to soften after soaking for a long time, have peculiar smell, and are difficult to open. Therefore, in terms of straw material, the best alternative is the straw, but the cost is higher than that of the paper straw."

On the market, the price of an ordinary plastic (pp) straw is 2~3 cents, and the price of a paper straw is 8~9 cents, which is three or four times directly.

And the straw with the best replacement performance is about 1 hair 3 to 1 hair 5.

Although the straw is the best to use, the disadvantage is also obvious, that is, the cost is too high.

Chen Hao did not speak, but looked at Chen Chong.

He believed that Chen Chong said so much, not to tell him that the cost of milk tea shops has risen.

Whether the cost of the milk tea shop increases or decreases has nothing to do with him, nor does he care.

Feeling Chen Hao's gaze, Chen Chong said in a deep voice: "The production of straws requires raw material polylactic acid, and the raw material synthesis technology is very difficult, and the market share has long been occupied by foreign companies such as NatureWorks and Cobion-Place. According to the data I found At present, the global production capacity of polylactic acid is only one million tons, and the total effective production capacity of domestic polylactic acid is only 142,000 tons, but it still needs to be imported.”

"Is the technical barrier high?" Chen Hao frowned.

Chen Chong's response made Chen Hao's heart clouded with dust.

"Technical barriers are high! There are two methods for preparation, namely lactide ring-opening polymerization method and direct polycondensation method, and the lactide ring-opening polymerization method is widely used in industry. However, the synthesis and purification of lactide are currently The core technology and difficulties in the process flow, its harsh reaction conditions, complex process, high technical requirements, and high production costs are the main technical barriers for domestic enterprises to expand their production capacity, and they can only rely on imports."

Hearing this, Chen Hao was really surprised.

A small straw, the technical barriers contained in it are so high.

To put it simply, the production of the best straws to replace plastic straws currently requires raw material polylactic acid, and polylactic acid needs to produce lactide.

The point is this lactide...

The production technology requirements of this lactide are very high. At present, domestic enterprises are far behind foreign countries and can only rely on imports.

A few years ago, a ballpoint pen and a lighter could not be produced independently in China and had to rely on imports.

But after so many years, Chen Hao still thinks that the only areas where China lags behind foreign countries are high-tech fields such as science and technology.

Unexpectedly, a small straw stumped Huaxia, which has a population of 1.4 billion.

This is also a realistic feedback... China is limited in many technologies by foreign countries, and it is far behind in technology research and development, and the road to independent research and development is still very long.

Chen Hao looked at Chen Chong, "So what are your thoughts?"

"Principal, I think our country needs to achieve independent research and development not only in the field of chips, but also localization in the production of lactide!"

Chen Chong's eyes were fixed and he said very seriously: "Principal, I want to start the problem of tackling lactide production, open up the whole industry chain of lactic acid, lactide and polylactic acid, and realize localization!"

"Our country must stand up not only in terms of economic aggregates, but also in all walks of life! What foreign countries can do, we can do it in China!"

ps: Ask for a monthly pass, ask for a recommended ticket!

I checked the information all night, the chip, the mobile phone, and this material, the information was hard to find, and the delay was delayed, I am really sorry!
