SOURCES OF WASTE –

• Bharat Tannery Industry takes all the measures to limit the waste .

• It uses ecofriendly chemicals and before disposing to the rivers or nearby water bodies it performs the screening operation and other treatments .

• The company operates with good pollution controls , doesn’t expose local populations to health risk.

• But the processes of soaking, weaving, dying , liming , pickling , splitting , trimming leads to generation of waste water and some amount of solid wastes like hide scraps , skin and excess fats

• Chromium contamination and high chemical oxygen demand are typical problems associated with tannery effluents, both of which can pose serious risks to the environment and human health.

•  Toxins from this waste can leach into nearby soil and water, placing nearby residents at risk of contamination.

• Through inhalation of dust or fumes, workers in tanning facilities can inhale airborne chromium and this may risk their health.

• Main source of smells due to nitrogen and sulfur components use.

TREATMENTS OF WASTE GENERATED-WASTE WATER TREATMENT:

• The company follows the following treatment process:• Screening mixing settling aerated

lagoons

• Other ways to reduce contaminants in water are :

•  Using of trivalent chromium as it is far less toxic than chromium VI, water that is contaminated with chromium VI can be treated with an electron donor that converts the pollutant to its less damaging, trivalent state.

• Even bone charcoal, which is produced by burning animal bones, used as it has the ability to remove chromium from water.
