Pollution is the process of introducing poisonous contaminants into an environment. The issue of Pollution has become an essential topic of conversation in the last two decades.  Leather processing is now known to be one of the hot topics in the economic reforms of developing countries of the world today. This has also brought about planned awareness of environmental hazards, problems, issues, and solutions too. This awareness has, over recent years, aimed at protecting our environment as well as preserving it.

Also, due to impending environmental problems, a layman on the street is now savvier on ecological issues and how they can be able to tackle it to ensure a safer future. Economic regulations made by world governmental bodies have now made it a difficult phase for leather manufacturing development as well.

The leather processing industry now faces new challenges every day in carrying out specific tasks due to environmental Pollution, treatment costs, and health risks involved. However, in many modern countries, there has been newly derived ideas and inventions in applying the proper methods for leather processing.

Using both chemical and mechanical nuances, many concepts have been applied and are now one of the best methods used today.

Whenever Pollution is mentioned, the major industries that come to mind are crude oil and automobile industries. Rarely do people consider the leather manufacturing and tanning industry.

What most people do not realize is that the Leather industry contributes majorly to industrial pollution problems through the constant disposal of chemicals like lime, sodium sulfide, salt, solvents, etc. If the by-products from Tannery operations are disposed of on land or water bodies without appropriate treatment, they may result in severe pollution problems. The best way to control Pollution in the Leather industry is by treating effluents before disposal.

Cleaner technology has been applied to highlight the need for cleaner processes and limitations of product waste to have better control of Pollution in leather manufacturing processes.

In the case of pH measurement and applications, thee oxidization of chromium is inevitable as well as paramount in achieving the required results. As a significant cause of water pollution and a definite victim of Tanning, the presence of sulfate salts in chromium helps in lowering the amount of pH a. It works at a neutral range in the pH scale.
