Fleet 1 travels through the Grey Stream, in the year 3510.

Chen Xin and Ibn walked out of the cabin, and since they met 200 years ago, they finally came together, and then they didn't have long to explore the Great Magellanic system, choosing to join the migration fleet of the Triangular system.

Today is the day of Chen Xin's work, as a member of the Immigration Management Committee of the Immigration Fleet, she is busy because of the new material recycling technology sent from the Academy of Sciences a few days ago.

Ibn is a foil, and he can undoubtedly better show his wife's beauty when he stands next to his picturesque wife, and basically listens to his wife's words to help her do some hard work, which can be regarded as a relaxing time.

They arrived at the training center in the education district, where the first batch of selected immigrants arrived at the announced time, lined up in a neat line, and waited for the guidance of the staff.

"Dear immigrants, today I will introduce to you the new material recycling technology released by the Academy of Sciences on behalf of the Migration Management Committee, which will be used to increase the degree of recycling of our materials......

Chen Xin said above that the new material recycling technology is expected to play a considerable role in the migrant fleet, because for the migrant fleet, it is a closed individual, and it is constantly operating inside, consuming food to produce garbage, manufacturing products to leave waste residue and pollution, but there are not many opportunities to replenish.

Therefore, if there is any way to reuse the completely useless garbage, pollution, discarded, and non-recyclables, it will undoubtedly reduce the fleet's thirst for supplies to the extreme in 500 years.

The new material recycling technology proposed this time, from a certain point of view, it has reached the height of ancient alchemy, which can convert manure into gold, it relies on the advantage of massive energy, through various chemical reactions, atomic decay, to reduce various substances, or to reduce garbage to raw materials, and put it back into production, and for the immigrant fleet that is not lacking in dark energy, energy is not a problem, thus increasing the degree of recycling materials.

Compared with the material recycling methods applied by human beings in ancient times, the new material recycling technology promoted by this generation of scientific sciences is better than that of ancient times in terms of conversion rate and comprehensive complexity, and can treat the messy recyclable materials relatively uniformly, "melt", and then become a variety of raw materials.

After Chen Xin's clean introduction, the topic of her professional background was explained by her in simple terms, and the following applause was ushered in.

The immigrants were then placed in a cabin in the education area to receive a memory writing process, which lasted about six hours for each person, and there was a 90-minute assessment, which Chen had to watch patiently as they passed.

The process was boring, but with Ibn standing next to her, she still had something to do, and the thought that after the new material recycling technology was popularized, their garbage would be reduced by more than 90%, and the material recycling rate would be as high as 80%, which made her full of energy.

"My dear, if the material recovery rate is as high as 80%, doesn't it mean that for every 1 ton of goods produced, after a period of time, 0.8 tons of goods will enter the market cycle again, and 0.2 tons will be completely discarded as garbage, and during this period, the fleet will continue to extract energy and mineral deposits on the planet near the star stream to replenish and put into production, one plus and one subtract, will there be more and more materials?"

"I don't particularly know what Commander Qiao means by this, what I can say is that your reasoning sounds fine, could it be that these materials will be of other use?" Chen Xin was immediately stopped by Ibn for a moment, but her answer was a little sloppy, because she didn't realize the deep meaning of the increased recovery of materials.

……

The immigrant fleet wants to popularize the new material recovery technology, and the way of writing through memory is one of the steps, and Chen Xin's work in the afternoon is to check the implementation of the new material recovery technology inside the starship.

Her first stop was the immigrant settlement, which was like a city, each of which could accommodate at least 100,000 people, and consisted of compact cabins, allowing so many people to squeeze into the nearly 5-kilometer-long national starship.

She inspected the renovation of public facilities in the settlement, all the citizens' domestic garbage, excrement, sewage, waste energy, etc. are usually gathered together through pipelines and other means, so since it is necessary to use new material recycling technology, these things will no longer be easily discarded, and the ancient material recycling technology will no longer be used, after all, the use of old public facilities to deal with it is undoubtedly a bit backward and overwhelming.

The Academy of Sciences has redesigned the processing mechanism of the different pipelines so that the different materials can be processed in a more systematic way of sorting and integration, and then they will be transported to the corresponding factories in the industrial zone for processing, depending on the type.

If the proportion of human material recycling before the 20th century is no more than 5%, in the 20th century, after the concept of sustainable development, pollution reduction, green embracing and other concepts was proposed, the proportion of material recycling is 30%, and after the promotion of primary new material recycling technology, the proportion will reach 80%.

Chen Xin inspected the operation status of the pipeline and saw that the public facilities had been renovated and were in stable operation, and the garbage generated by the migrants' lives was continuously incorporated into the new system for disposal.

Of course, the garbage generated by the immigrant settlement will definitely not account for the largest amount, and Chen Xin's second stop target is the public area, including the free activity area on the starship, the warehouse area, the manufacturing area, etc.

Unlike migrant settlements, where there are dedicated garbage disposal pipelines, all recyclables found in public areas are scattered and robots need to be responsible for collecting garbage and delivering it to the designated location.

The specific recyclable materials may be food scraps, commodity packaging, containers, damaged clothing consumed by immigrants, or fallen leaves in green areas, animal carcasses, or slag from the production and manufacturing process of mining deposits on planets near the star stream.

Chen Xin can't check them one by one, she can check every detail through the starship's artificial intelligence, according to whether there is a problem, and then find the cause and find a way to solve it.

Her third stop is the recycling plant, which has been expanded and refined on a small scale to have more processing equipment, and now the materials transmitted back from each pipeline will be processed in the corresponding equipment.

The recycling plant consumes as much as five times more energy than in the past, because they can draw energy from dark energy, and they don't have to worry about running out of energy at all.

Soon all kinds of processed materials are piled up, and then transported to the warehouse area by transport trucks to be restocked, which will be re-supplied for the daily life of immigrants, various expenses of spaceship voyages, and so on.

The inspection of the recycling plant is correct, and Chen Xin's work today is completed, but when it comes to the entire fleet, the promotion of new material recycling technology will continue for a while, so it does not mean that she can sit back and relax. (To be continued.) )
