In a world-first initiative, we are purifying the carbon dioxide strategy at our manufacturing facilities. Our waste management

Our efforts are also geared towards creating value from waste waste, the moisture content of hazardous waste is down to less than 20% w/w.
Charting the circular economy course through effective waste management
As part of our efforts to promote sustainable growth through circular Benefit
economy, we have adopted the 3R (Reuse, recycle and reduce) waste The installation of the solar dryer resulted in reduction of hazardous waste generation from 480 MT to 199 MT in 11 months

The importance of mangrove ecosystems lies in the
benefits and services they offer. These include providing
habitats for a wide range of species, and as a source
of food, medicines, and forestry products. Mangroves
functions also indirectly support economic activity, such
as through nutrient recycling, water purification and
flood control.

to the creation of livelihood opportunities for local
