This early exposure of the "toxic capsule" incident attracted widespread attention in early 2012.

The toxicity of toxic capsules is beyond the standard of chromium, while chromium comes from industrial gelatin. Along this processing chain, people's eyes begin to focus on the source of raw materials - chrome containing leather corner waste.

Leather crumb containing chromium has always been the main raw material for the production of industrial gelatin. After processing and meeting the product standards, industrial gelatin is usually used in the industries of sheet metal, paper making, printing, metallurgy and so on. Due to the requirement of food and pharmaceutical grade gelatin index, industrial gelatin is not allowed to be used for food and pharmaceutical production. Therefore, chromium containing leather waste as raw material of industrial gelatin itself does not have any problems. The focus of the problem is mainly on the circulation, management and supervision of products.

< p > however, in some parts of the area, some extreme measures have been taken to treat the chrome containing leather waste as a hazardous waste. It is forbidden to be used in the production of industrial gelatin. This kind of treatment is very unfair to tanning enterprises. Originally, the leather scrap as resources should be identified as hazardous waste, which not only caused the waste of resources, but also increased the high cost of processing for enterprises.

The damage caused by the illegal behavior of the downstream enterprises and the lack of supervision links should be paid by the tanning enterprises, which greatly damages the interests of the law-abiding tanning enterprises.

< p > < strong > how many dangerous characteristics are there? The identification standard is the leading factor! < /strong > /p >

< p > > from < a href= "http://sjfzxm.com/news/index_z.asp > > Technology > /a > regulations level, the Ministry of environmental protection issued the list of hazardous wastes in the national hazardous waste list issued in 2008. It has made clear the identification of the hazardous waste characteristics of" Chrome "leather debris, that is," there is an exceptions to the complex sources and the dangerous characteristics, and the state has a clear identification standard of hazardous waste ".

At present, the identification standards of hazardous wastes are corrosiveness identification (GB5085.1-2007), acute toxicity screening (GB5085.2-2007), leaching toxicity identification (GB5085.3-2007), flammability identification (GB5085.4-2007), reactivity identification (GB5085.5-2007) and toxic substance content discrimination (GB5085.6-2007).

According to the above standards, all indexes of chrome containing leather scrap meet the standard requirements, so it can be proved that they do not possess the characteristics of hazardous wastes.
