Where Is The Chrome Containing Leather Crushing Road?

< p > a large number of media and people, without knowing the leather industry, can not tell the difference between trivalent chromium and six valent chromium, and pfer illegal practices between illegal gelatin factory and illegal pharmaceutical factory to the leather industry, and exaggerate it.

The environmental protection department has intensified supervision over < a href= "http://www.91se91.com" > leather scrap > /a >, which has affected the utilization way of leather scrap.

For leather tanning enterprises which are implicated by the innocent, a large number of chrome containing leather scrap can not go for a time, and a large backlog in the factory area has become a problem in the industry.

< /p >

< p > for this purpose, China's < a href= "http://cailiao.sjfzxm.com/Matertial/show/default.aspx" > Leather Association < /a > technical Specialized Committee set up an expert group. In view of the actual situation of the industry, the characteristics and toxicity of trivalent chromium, as well as the international view and treatment of chromium containing leather debris, a large number of research and analysis have been done, and a research report on the properties of chrome leather scrap has been formed.

After communication, the Ministry of environmental protection, solid waste department, the solid Research Institute of the Chinese Academy of Environmental Sciences and some representatives of Specialized Committee of China Leather Association held a meeting in March 13, 2013 to discuss the issue of whether chrome containing leather debris was classified as hazardous waste in the Ministry of environmental protection.

Zhong Bin, director of the solid work department of the Ministry of environmental protection and the director of the solid waste Research Institute of the Chinese Academy of Environmental Sciences, Su Chaoying, director of the China Leather Association, the Chinese Academy of engineering, the Standing Committee of the CPPCC National Committee, Shi Bi, the vice president of Shaanxi University of Science and Technology, Ma Jianzhong, director of technical Specialized Committee of the China Leather Association, Zhong Ningqing, vice president of China leather and footwear research institute, Li Tianduo, Dean of the school of chemistry and pharmaceutical engineering, Shandong Light Industries College, senior engineer of Zhejiang Institute of environmental science and technology, Wuhan steel, Luo Qingba, assistant counselor, environmental consultant of the Zhejiang tanning Enterprise Association, Li Junxian, vice president of the Red Dragonfly Footwear Industry, and Deputy Secretary General of China Leather Association, etc.

At P, Su Chaoying, chairman of the Ministry of environmental protection, introduced the main purpose of the report to the Ministry of environmental protection: "it is understandable to classify leather waste as a dangerous waste from the perspective of environmental regulation. But in practice, it seriously hindered the recycling of chromium containing debris and caused great trouble to enterprises and industries. The China Leather Association technical Specialized Committee set up a group of experts on this issue to carry out scientific argumentation on chromium containing leather fragments, and take this opportunity to discuss with the Ministry of environmental protection, hoping to remove the chromium containing leather debris from the list of hazardous wastes, which is conducive to resource utilization."

Academician Shi Bi then introduced: "the chrome tanning agents used in tanning process are trivalent chromium, and do not involve six valence chromium. The whole world is like this. There is no problem in the history of chrome tanning for more than 100 years." P

In addition, the society has a wrong understanding of trivalent chromium and six valent chromium, and the relationship between the two is not clear. In fact, trivalent chromium can hardly be pformed into six valent chromium under natural conditions. This is widely recognized by scholars and governments both at home and abroad, and also has sufficient scientific basis.

On the other hand, the European Union, the United States, Japan, Taiwan and other places all treat chrome containing leather scrap as a general solid waste. Our country has also undergone numerous experiments for toxicity identification, which fully meets the standard requirements and therefore does not possess the characteristics of hazardous waste.

Therefore, under the condition of standardized management, it is the best way to reclaim leather, industrial gelatin and other raw materials.

"P >," Tong Wu Steel senior engineer said: "China's renewable resources and other resources recycling enterprises do not have the qualification of hazardous waste disposal. For those enterprises that use leather scrap as raw materials, they are unwilling and difficult to obtain the qualification of hazardous waste disposal. However, at present, there are very few hazardous waste centers with qualified qualifications, and even some provinces do not have one. Therefore, many tanning enterprises can only keep the chromium containing leather scrap in the factory, which leads to increased pressure on enterprises and the pressure on the management of the environmental protection department.

From the test results, chromium containing leather scrap is also toxic and does not possess the characteristics of hazardous wastes.

< /p >

< p > we are familiar with the historical process of converting chrome containing leathers from Taiwan to general solid waste in the area of Luo Qingba. "It is currently treated by the European Union and the United States as a general solid waste for the properties of chrome containing leather waste. Taiwan once considered it as a hazardous waste before December 2006, but after extensive research and experience from abroad, it has been regarded as a general waste management and has not had any environmental and regulatory problems. Therefore, leather scrap is feasible in resource utilization.

< /p >

< p > then, the chief bell of environmental protection department also put forward several problems for the < a href= "http://www.91se91.com/news/" > leather industry < /a > chromium containing scrap, such as the output of China's leather scrap, the current way out, and potential problems.

The experts answered the questions one by one.

< /p >

< p > during the communication process, the relevant leaders of the Ministry of environmental protection have systematically understood the actual situation of chromium containing wastes in the leather industry and the problems they face in the disposal. The director of the ring academy has also approved the viewpoint that there is no danger characteristic from the technical perspective. However, considering the difficulty of environmental supervision in China, it is still difficult to remove it immediately from the list of hazardous wastes, but the existing problems can be solved by formulating tannery industrial waste management standards.

< /p >

< p > how to solve the practical problems of the enterprise as soon as possible is very critical. The China Leather Association will continue to explore with the Ministry of environmental protection as soon as possible and find a feasible solution.
