NATURAL CAPITAL Envisioning a climate- resilient future

Environmental conservation is a key aspect of our sustainability framework. We prioritise responsible business operations, ensuring judicious consumption of the natural resources and effective management of our environmental footprint. We are actively implementing rigorous upgrades, controls and processes in our manufacturing units to operate efficiently and sustainably.

KEY INITIATIVES TAKEN IN FY 2023-24

Emission Management

Deepak Nitrite is strategically focussing on enhancing the plant’s energy efficiencies by upgrading them with energy-efficient equipment and technology. These measures ar effectively bringing down our energy consumption and emissions elevating plant’s efficiency. We are consistently increasing the proportion of renewable energy in our energy portfolio and our R&D team is striving to optimise the product yield. We are actively involved in tree plantation initiatives to offset the carbon generated by our operations. During the year, we installed a 20 TPH multi-fuel boiler utilising bagasse, husk, agro-waste and coal, aimed at reducing scope 1 GHG emission.

WATER MANAGEMENT

We have embraced the principles of reduce, reuse and recycle to define our approach to water management and water conservation.

Our Water-related ambitions

Make our operations water-efficient
Achieve water positivity

Reduce our freshwater consumption
Achieve zero-liquid discharge (ZLD) for our facilities

Our Hyderabad Unit operates as a Zero Liquid Discharge (ZLD) unit encompassing the following advantages:

Effluents with high TDS are initially subjected to primary treatment and are processed through a multi-effect evaporator system. The concentrate effluent is subsequently directed to a fluidised bed recovery system to extract sodium sulphate salt, while the treated water is reused in the process
Sewage is treated in the Sewage Treatment Plant, followed by processing in the Reverse Osmosis plant

In Roha and Dahej units, approximately 60% of treated water was recovered from total wastewater generated by the installation of Reverse Osmosis system.

GHG Emission

During the year, we have taken the following initiatives to promote water recovery for further reuse:

At Nandesari Unit, a Mechanical Vapour Re-compressor has been installed to recover pure water from Nitro Toluene effluent stream

At all locations, Reverse Osmosis system has been installed to recover water from Multi Effect Evaporator condensate

WASTE MANAGEMENT

We strive to optimise resource utilisation and waste minimisation. The waste produced during our manufacturing processes is disposed of responsibly, in accordance with the regulatory requirements outlined under Hazardous and Other Waste (Management and Transboundary Movement) Rules, 2016. We strictly adhere to the air emission standards laid down by Pollution Control Board and do not use any Ozone-depleting substances (ODS) in our operations. 100% of the plastic waste undergoes recycling through the CPCB-registered plastic waste processor (PWP), while the post-consumer waste is addressed through Extended Producer Responsibility (EPR) management. In accordance with the plastic management rules, we are offsetting 100% of our packaging materials associated with domestic consumers in India through an external agency. The external agency facilitates collection and recycling of plastic waste in a responsible manner. The Spent sulphuric acid and Mother liquor generated from production of Nitro Toluene during Nitration Process are directed towards the manufacturing of Mix Cresol, where they are utilised as a wood preservative. 100% Fly ash is delivered to the brick and tiles manufacturer in accordance with fly ash notification.
