On the production line of a company, one is called

The technology is being applied, which uses imported chemicals instead of traditional chromium, though the cost per square foot is more expensive.

The increase is about 0.3 yuan, but the leather products produced by this technology conform to the environmental standards of many European Union countries and sell well in the international market.

More than half of the 7 million fold sheepskin produced annually use chrome free tanning technology.

The plant tanning agent is a kind of tanning agent extracted from plants. Since 2008, the company used plant tanning agents instead of traditional chrome tanning agents in the production process of sheep skin. Although the cost of each square foot skin was increased by nearly 0.5 yuan, the use of new technology could reduce the chromium content to zero in the leather making process, since 2008, the plant tanning agent is a kind of tanning agent extracted from plants.

It is understood that due to the general biochemical method is difficult to degrade, chromium will usually accumulate in the environment for a long time, and long-term uncontrolled emissions will cause water pollution.

In fact, in addition to the use of vegetable tanning agents, tanning enterprises in Haining have been trying to reduce the amount and emissions of chromium.

In the leather making process, the technology of low consumption and high absorption of chrome tanning and the continuous reuse of waste chrome solution are being explored.

"These new technologies can reduce the amount of chromium in the traditional chrome tanning method by 30%, and the absorption rate will be increased to more than 95%, which will greatly reduce the chromium emission."

A technician from brother leather told reporters that the cost of sludge disposal will be greatly reduced in the later stage. That is to say, the chromium content in the sludge accounts for only 5%, and the chrome tanning waste liquid basically realizes zero discharge.
