China Environmental Protection Expo: Zhejiang Makes Brown And Green Cotton.

China

In low carbon life, clothes need not be dyed.

Zhejiang produces the most clothing in China, and the dyeing and finishing industry has a lot of pollution.

If cotton is colorful, the printing and dyeing process will be eliminated.

The Zhejiang Academy of Agricultural Sciences has spent more than 20 years brewing brown and green cotton, and experts say dyes can no longer be used if they can still grow red, yellow and blue cotton.

At that time, the cotton fields are red and yellow over there, so you can see them as a flower garden.

Black water discharged by factories is a great enemy of rivers.

If a permeable membrane is popularized, the wastewater from factories can immediately change into tap water.

The membrane has small pores, the diameter of the pores is only 1 billion points of 1 meters, and the water molecules can pass through other pollutants.

Unfortunately, making this kind of membrane is not easy and the selling price is high.
