Blacksmith Institute and Green Cross organization published the ten most serious problems in November.

contaminated

The "problem" report calls the tanning industry the world's most polluted sector. An independent consultant from Australia, Dr. Catherine Money, a former research fellow of the federal scientific and Industrial Research Organization (CSIRO), sent an open letter to the International Association of leather chemists and craft Societies (IULTCS) to clarify the use of chrome tanning agents in leather industry.

In her letter, she also refuted some misleading claims in the report.

Open letter (excerpt)

The Blacksmith Institute and the Green Cross organization have released their most serious pollution industry and pollutant reports every year since 2006.

In their successive reports, they aim at chrome tanning agents and tanning industry.

information

It is misleading and vilified.

2011 of the reports remain the same, and they should be withdrawn.

One of the many fallacies of the report is that there is no discrimination between trivalent chromium and six valent chromium.

Trivalent chromium is a kind of chromium sulfate (BCS). It is widely used in leather industry, and is harmless and harmless.

While the six valent chromium is toxic and harmful,

concentration

No danger at low altitude.

Blacksmith's report blamed India's six chromium pollution problem on factories using BCS.

Many countries have faced this problem in the past, but now they have been basically solved.

Moreover, most importantly, this is a problem arising from a chemical enterprise rather than a tannery.

The Green Cross organization in Argentina is now promoting a cleaner production plan to tanning enterprises, claiming to achieve zero discharge of chromium waste.

This is an impossible goal and unnecessary. The plan has now been widely questioned.

For the discharge of chromium waste, the world should formulate a scientific restrictive measure, and the Green Cross should learn to examine their plans from a scientific perspective.

In addition, some leather manufacturing enterprises, such as Nike, Adidas and Puma, recently announced that they will achieve the goal of zero emissions of all hazardous substances in their circulation in 2020.

In fact, it is unrealistic, unreasonable and unnecessary to achieve zero emissions of harmful substances.

And any list of harmful substances should be based on scientific judgement.

Of course, it is necessary to fully understand the environmental impact of chrome tanning tanning leather, because in the foreseeable future, chrome tanning agents will still be widely applied in the leather industry worldwide.

Trivalent chromium is harmless and controllable. Only sewage and discharge should be minimized to a reasonable level.
