NLCIL maintains a strong focus on sustainable development with conservation of natural resources being integrated into all activities. NLCIL’s strategy is to have minimum impact on environment and fulfil the aspirations of various stakeholders. Thrust areas include environment improvement programme such as eco restoration in mines, massive afforestation programmes, rainwater harvesting, waste utilization, and conservation of bio-diversity, effective water and energy management, pollution control, mitigating the impact of climate change. NLCIL is proactive in training its employees in Environment Management.

The company also pursues appropriate standards in safety, quality, energy efficiency, clean mining techniques, emission controls and environment management

Further to NLCIL’s implementation of the philosophy on sustainability, NLCIL India also meets the statutory requirement as stipulated by the Department of Public Enterprises (DPE) over its Guidelines on Sustainable Development for Central Public Sector Enterprises (CPSE).

NLCIL has framed its own Sustainable Development Policy taking into consideration the magnitude and nature of core business activity and fulfilling aspirations of the Stakeholders and protecting the Environment. NLC India is undertaking number of sustainability development activities/projects year after year.

During the Past three years, NLCIL has completed the following Projects towards Sustainability Development.

1.0 Ecology: Reclamation and reuse of lands in Mines.

Excavation of soil is a pre-requisite for extraction of lignite. Specialized Mining Equipments are used to mine lignite. Several hectares of land is disturbed every year due to the Mining operation. Even at the Project formulation stage, NLCIL India has planned for refilling and reclamation of mined out area to maintain the productivity of land and to control pollution such as soil erosion, water pollution etc. The concept of reclamation is given due importance. NLCIL is reclaiming the mined out area and overburden dumps. Integrated Farming System (IFS), a novel method has been developed in collaboration with Tamilnadu Agricultural University for reclamation of backfilled areas. The external over dumps created during the initial opening of the Mine cuts are being converted into vegetative one making it fit for habitation. NLCIL has also developed techniques by carrying out a Project named Slope Stabilization of the Mines for afforesting the Over Burden dumps. Every year about 100 hectares of mined out land is reclaimed for afforestation, agricultural and horticulture crops. An orchard has been developed by planting different varieties of fruit bearing trees and also herbal cultivation is undertaken in the reclaimed area to cater the needs of Ayurvedic dispensary of NLC India and also public. The yield from this reclaimed land is as good as the yield from natural and normal agricultural lands. This year (2017-18), it was planned to reclaim about 100 hectares of mined out land in all the three operating mines of NLCIL at Neyveli and about 132.37 hectares of land has been reclaimed. No of trees planted is 1,09,395 against the target of 1,00,000.

2.0 Sequestration of CO2 and Production of Biofuel from Flue gas of Thermal power plant

NLCIL has put up a pilot plant to sequest CO2 from one of the boilers by erecting photo-bioreactor of 1000 litre capacity and algae is produced. Algae are processed to produce biodiesel. NLCIL has successfully carried out this pilot project for the first time in India as algae grows faster and absorbs more CO2 than a tree. This project is first of its kind as a the CO2 sequestration is carried out in an operating Thermal Power Station-I expansion to address climate change issue.

3.0 Renewable Energy Power generation

As a diversification move and as a socially responsible Corporate Citizen, NLCIL has taken following Green Energy initiatives to reduce Carbon foot print as well as sustainable power generation. • 140 MW (130MW + 10MW) Solar Power project is in operation.
• A 51 MW Wind power project commissioned at Kaluneerkulam in Tirunelveli district, Tamil Nadu is in operation.
• 300 MW Solar Power Project in Tamil Nadu is under implementation.
• 709 MW Solar Power Project in Tamil Nadu is being processed for implementation.
• 20 MW Solar Power Project with 8mw hr battery energy storage is standing; a first of its kind in India at Andaman and Nicobar island is in process ten completed
• Various State Governments are pursued for implementation of Solar Projects in their States by NLCIL.
Roof top solar: NLCIL also initiated a proposal to utilise the roof tops of Non Residential buildings in Neyveli and implementation of 1 MW roof top solar projects is under progress.

4.0 Introduction of New Technology towards increased efficiency and reduced carbon footprint

a. CFBC Technology
CFBC Technology for lignite power plants which has less NOX, SO2 emission and resource conservation. This technology has been adopted at Barsingsar thermal power project and Neyveli Thermal power station-II expansion.
b. Implementation of Supercritical and Ultra Super Critical Boilers (660 MW/800MW)
Supercritical and Ultra super critical boilers (660 MW/800MW) are planned for upcoming Lignite / coal based projects under implementation.

5.0 Resource Conservation / Reduction of waste

a. Reduction of emissions/energy consumption:
Every year the stringent norms are fixed for specific fuel consumption, secondary oil consumption and Auxiliary energy consumption for Mining and Thermal Units. The norms are fixed based on CERC guidelines, present system configuration, life of the plant etc. NLCIL's Thermal Power Station-I Expansion was adjudged as Best Environment Managed Thermal Power station on all India basis based on Energy consumption and pollution control. The Units are instructed to meet the energy conservation norms. Through various conservation measures about 22.42 MU was conserved.
b. Water Conservation:
The entire quantity of storm water pumped during mining of lignite of about 20,000 GPM is used to meet the domestic water requirement of Township and to meet the water requirements of Thermal Power station-II and its expansion (1970 MW). The treated waste water from the mines benefits the nearby agricultural community and pumping out of ground water for agricultural purposes in the nearby villages is prevented. Development of a new lake to harvest rain water with boating facility in Mine IA region is being carried out. Desilting of lakes have been carried out by CSR department in lakes surrounding in and around Neyveli and Palm tree saplings are being planted around them for conservation purpose.
c. Waste Utilisation:
The fly ash generated in the power stations is utilized for constructive use like cement manufacture, fly ash bricks blocks etc. besides number of innovative technologies developed on the recycling of fly ash. Construction waste material is used in concrete manufacture. Plastic waste is converted into pellets and used with tar for road laying. Fly ash is used for road formation and Ash bund formation. NLCIL is committed towards 100% fly ash utilisation in its lignite/coal based Thermal power projects and has achieved the same in its Thermal Power Stations at Neyveli, Tuticorin and Barsingsar.
d. Muncipal Solid Waste Disposal:
Apart from Greening the Township by planting more trees, a new system has been introduced for the first time in Block-5,6 & 7 of Neyveli township for door to door collection of domestic waste in a segregated manner and processed and this will go a long way in the improvement of environment ,health and Hygiene of Neyveli Township . NLC India Limited is always in line with National Mission of “Clean & Green India” and is implementing the latest technologies in Environmental arena for the past 6 decades and is constantl
