Leather processing is an important industry in China, and the discharge of chromium waste has been severely circumscribed. Though traditional processes for treating chromium waste have been widely used in tannery plants, technology adopting high efficiency and economic simultaneously is deficient. In order to develop an economic treatment for tannery waste, a mixed alkali of sodium hydroxide an...

This study attempts to understand the socio-economic conditions and working condition of leather tannery workers. The leather tanning industry and leather related industry give employment and business opportunities for many people. The rising cost of living compels the tannery workers to take up the job. The tannery workers are exposed to lot of chemicals for low wages. But this leads to health...
