< p > Wenzhou is known as the "shoes capital of China (shoe store)". The Wenzhou shoes, which are famous for their shoes, are developed at the expense of polluting the environment.

The green production technology developed by Wenzhou University Key Laboratory of leather engineering has made tanning no longer "smelly".

< /p >

< p > Wenzhou has more than 4300 leather and shoemaking enterprises and about 400000 employees.

Leather and shoe-making enterprises gathered in the twin islands is also known as "psoriasis".

To explore a green and sustainable development of leather revolution is the mission of Wenzhou University leather laboratory.

< p > reporter walked into the laboratory, the staff demonstrated the tensile machine and other equipment, testing leather strength, hardness and so on.

Years of dealing with leather, members of the lab in leather have trained new skills - buying leather goods and leather shoes, and identifying them by hand.

< p > according to Lan Yunjun, director of the laboratory, tannery clean production and water saving technology were introduced from Spain and technological innovation was carried out in Wenzhou.

The project includes the recycling technology of pickling solution, low consumption and high absorption chrome tanning technology, and the recycling technology of spent chromium solution.

Among them, the pickling liquid recycling technology can save 70% of the amount of water in the process and the amount of salt, reduce the amount of sewage discharge, and reduce the environmental pollution caused by salt.

< p > chrome tanning has been in leather processing for more than 100 years, and a mature processing technology has been formed.

However, with the development of the global economy and the progress of the society, the pollution and disposal of chromium have attracted more and more attention. Therefore, the development of chrome free tanning products is pressing.

At present, the LTA series metal (chrome free) compound tanning agent and auxiliary auxiliaries for chrome tanning agents have been successfully developed.

< /p >

< p > main tannery cleaner production and water-saving technology, Wenzhou University leather Laboratory for many years for leather enterprises to save more than 40%, resulting in economic benefits of 7 billion yuan.

The laboratory is also carrying out technical services with more than 10 enterprises in Wenzhou, Haining, Ningbo, Huzhou and Lishui in Zhejiang province.

In Wenzhou, the technology has been popularized in Pingyang tannery area.
