First of all, a 30,000-hectare area is equivalent to the size of 30,000 standard football fields. This scale is nothing, any interstellar foundry is more likely to occupy half a planet or something. But after all, this will be an industry that officially belongs to her, a little smaller, let's take our time.

After the area is divided, the infrastructure robots will be thrown over, and then there will be various production lines, which will directly manufacture and produce various building materials on the spot, and be fully automated. After this step, the infrastructure robot is recovered, the collection robot is put into it, and the intelligent brain management of the whole plant is set up, and the equipment for processing garbage, decomposing materials, sorting and sorting, and refining substances repeatedly is installed in it...... In a short period of time, a garbage treatment plant was built, and a batch of solid waste was put into it, and after various steps, a lot of raw materials were extracted.

If Ling tastes the sweetness, this batch of raw materials, if they are sold or processed for secondary processing, will be quite good. In this garbage heap, it is even possible to decompose the raw materials that are quite scarce on the market. For example, a stable and scarce material in two states of solid and liquid, called krypton copper, is widely used in intelligent light brain for conduction, there is no such raw material in nature, the cost of synthesis is extremely high, and it requires technology above the second level civilization, and the value of one gram is above 90 million Galaxy coins, which can be easily obtained by refining, and it can easily be obtained as many as several hundred grams.

In addition, although some products are destroyed, they are not useless, and the technical value contained in them is the core value, those warships, mechas, weapons, etc., which were destroyed by the war, or some retired power cars, optical brains, robots, etc., simply cover all aspects.

These technologies, when a product is gradually decomposed, will be gradually displayed on the optical brain, listing the principle, and tracing the source of the technology. Of course, this is not the original technology of the Sunset Civilization, this is what Ling Heng designed and added after referring to Ling Ruo's idea, and he modified the original light brain system for this purpose, set up the program, and added new content. So these technologies eventually came to him in a steady stream and became his foundation. This can be said to be ingenious.

These pieces of waste products are easy to dispose of, but various contaminants, radioactive materials, nuclear contaminants, subunit contaminants, contaminants...... The water pollution and air pollution caused by it are more difficult, and it can be said that it is a galaxy-level problem, and it is a deadly pollution that accompanies scientific and technological progress, and there is no solution at present. This matter bothered Ling Ruo for a while, and it was later resolved. She designed a kind of sphere called "Yoyo", which is set up with a subspace (this technology has no problem after Ling Heng cracked the black box of the Sunset Clan) can be placed in water and air, collect these pollutants, put them in a special container, and plant flowers around it, using the characteristics of flowers to convert energy for absorption and transformation. At present, the effect is not very obvious, but over the years, it will definitely be effective!

There is a lot of garbage in the garbage star, the entire garbage star is overwhelmed, scarred, and rancid, and the entire surface of the sphere, at least a hundred meters high, is paddled on the garbage, and dealing with such a large amount of garbage can not be done overnight, at least ten years, or even hundreds of years. However, with Ling Ruo starting to set up a factory and using flowers to make changes, the ecosystem of the garbage star began to recover.

The people who lived on it gradually found that the sky was not so gray, the clouds were not so irritable, the acid rain slowly fell very little, the radiation in the air became smaller, the ground began to sprout green shoots, the garbage mountain, looking smaller, people rarely became zombies, and the character of the mutant beast began to stabilize......
