Significant
initiatives have been undertaken over the years
to continuously improve environmental performance
while clearly focusing on the utilisation of waste
streams for value addition
These
include:
 |
In the sale of the by-product gypsum to the
cement industry, HLCL played a pioneering
role in effectively utilising waste. |
|
Sale
of sodium silico fluoride, a by-product from
STPP manufacture, to the glass industry. |
|
Utilisation
of spent acid from LAB sulphonation in single
super-phosphate fertiliser manufacture. |
|
Utilisation
of wastewater as process water in manufacturing
operation. |
|
Continuous
scrubbing of exhaust gases from the sulphuric
acid plant to limit SO2 emission
to <1 Kg/T sulphuric acid, which is significantly
better than national standards. |
