While introducing, Liao Cheng led Xu Chuan through the factory door and into the spacious factory.

After putting on dust-proof clothing and footwear, Xu Chuan followed the other person's footsteps and walked around the factory, especially visiting each processing area and understanding the production tasks each factory area was responsible for.

The fully automated lithium-sulfur battery production line, from ingredients to coating, rolling, lamination... can all be carried out automatically, and the efficiency is quite high.

Xu Chuan just went through these things once, and after having a rough idea in his mind, he said: "Take me to see your industrial wastewater treatment center."

On the side, Liao Cheng was stunned for a moment, then nodded quickly and said: "Okay, okay."

After a slight pause, he continued: "Well, Academician Xu, our wastewater and waste materials are all processed in a centralized manner. It is on the other side of the factory, and the road may be a little far."

Xu Chuan: "It doesn't matter, go and have a look, it doesn't matter if it's further away."

"Okay, then I'll take you over to take a look."

.......

Along the road inside the park, the group came to the centralized waste processing center.

The battery manufacturing industry plays a vital role in the global energy transition, but the wastewater generated during its production process contains heavy metals, organic matter, and acid and alkali substances.

If not handled properly, it will cause great harm to the environment.

On the way to the centralized waste processing center, Liao Cheng took the initiative to introduce: "Generally speaking, battery manufacturing involves heavy metals such as lead, cadmium, nickel, cobalt, and lithium. The heavy metal ions in the wastewater are bioaccumulative, toxic and toxic.

Long-term environmental impacts.”

"In order not to affect the environment and not pollute groundwater, our factory has centralized treatment of wastewater and waste materials during the production process."

"Heavy metal wastewater treatment through chemical precipitation, ion exchange resin, electrodeposition, electroflocculation and other methods..."

"On the other hand, our factory invests at least 5% of its profits every year to focus on upgrading wastewater and waste treatment technology, optimizing production processes, reducing the use of heavy metals and organic solvents, using environmentally friendly raw materials, etc."

"This is a rigid rule at the headquarters."

"It is no exaggeration to say that our annual investment in environmental protection is the highest among battery manufacturers."

Xu Chuan listened and looked at the centralized waste processing center, which covers a large area.

BYD can use 5% of its annual profits to develop waste treatment technology. This is actually his mandatory requirement, but the factory director Liao in front of him does not know the inside story.

Just as a group of people walked to the entrance of the waste processing center and were about to enter, a uniformed staff member came over and stopped them.

"This is an important factory area. Outsiders are not allowed to enter. Which department do you belong to? Do you have an entry and exit permit..."

The questioning was interrupted midway, followed by a voice full of surprise.

"Huh? Kawako... who are you? Damn it, Kawako, why are you here?"

Hearing this way of greeting, Xu Chuan was stunned for a moment, followed the voice and looked over, with a surprised expression on his face.

"Brother Hou? Damn it, why are you here?"

Seeing the thick face across from him clearly, Xu Chuan asked in surprise.

The person who would stop them was none other than the boy from his village, Xu Hou.

A few years ago, he attended the other party's wedding and served as the best man. He didn't expect to meet him here.
