Tata Steel has set global benchmarks in environment conservation by incorporating best available technologies within its extensive conservation initiatives.
Tata Steel ensures energy conservation primarily through use of energy efficient technologies and processes that enable higher energy reduction and efficiency. The Company supports the development and shortlisting of positive technologies through joint initiatives with countries across the globe, besides engaging with academic & research institutions like the Indian Institute of Technology, Kharagpur, Indian Institute of Science, University of Sheffield etc. for studying, and working on related projects. Tata Steel is also a part of an effort initiated by the Government of India, led by Indian Institute of Technology, to develop an energy efficiency roadmap for our country.
As a part of its energy conservation initiatives, Tata Steel‘s coal mines in Jharia and West Bokaro generate the majority of their power needs from coal rejects. Apart from producing energy-efficient steel that enables downstream consumers to reduce the quantity of steel in applications, thereby reducing the overall energy consumption, the Company has installed solar lights and LED lights to reduce electricity consumption.
Raw material conservation
Iron ore and coking coal are the two principal inputs and the largest spend for Tata Steel. As a responsible corporate citizen, Tata Steel is committed to conserving these non-renewable raw materials. Aware of the fast depletion of high-grade ore deposits, the Company works extensively towards ensuring future availability of iron ore and coking coal through responsible mining, efficient use of captive raw materials and minimising waste generation.
Tata Steel uses innovative ore beneficiation and extraction techniques to ensure efficient mining of raw materials. The Company adopts state-of-the-art resource efficient technology that minimises scrap generation and enables use of lower grades of iron ore and coal within the manufacturing processes, without compromising on the quality of steel manufactured. This also reduces the overall consumption of iron ore per tonne of hot metal. To ensure mining capacity meets production requirements, Tata steel has undertaken various raw material growth projects in parts of India, Africa, Canada and Australia.
Tata Steel adopts a structured management approach, awareness, and technological intervention, to not only conserve water but also provide safe and steady water resources for industrial as well as human use within its operations. The Company has taken extensive initiatives in this direction.
Tata Steel has been conserving water through –
- Water recovery and recycling initiatives
- Water footprint assessment and reduction exercises
- Large-scale rainwater harvesting projects
- Water conservation at the raw material locations
- Protecting water sources at the mines
- Artificial recharge of ground water
- Ensuring zero water discharge at the collieries
Tata Steel deploys the 3R principle of reduce, reuse and recycle. Based on this principle, the Company has undertaken various waste management initiatives. As a result of its vast initiatives in this direction, within a year Solid Waste Utilisation improved from 75 per cent to 83 per cent in FY 13. Tata Steel intends to achieve 100 percent Solid Waste Utilisation by 2020.
The Canteen Waste Management at Steel Works is one such initiative where Tata Steel uses waste from its canteen to produce manure and cooking gas. Besides, projects under the 'Zero Effluent Discharge' project have been commissioned in phases to reduce discharges from operations of water substantially.
Tata Steel's various key Environment Sustainability Projects for Jamshedpur were formally inaugurated in the City on July 25, 2015. The event started with the flag-off of Road Sweeping Machine on Office Road, followed by the launch of facilities at Municipal Solid Waste Transfer Station near C.H. Area petrol pump, Modular Bio Gas Plant at Tata Football Academy and Liquid Medical Effluent Treatment Plant at Tata Main Hospital. Dr. Amitabh Kaushal, I.A.S, DC East Singhbhum and Mr. T.V. Narendran, MD, Tata Steel along with other dignitaries graced the event with their presence.
In line with the conditions laid out under 'Environment Clearance' and 'Consent to Operate' and the Municipal Solid Waste (Management and Handling) Rules, 2000 enacted by Ministry of Environment & Forest, Government of India, Tata Steel decided to establish an Integrated Municipal Solid Waste (MSW) Management System for the command area of Jamshedpur. The following initiatives were identified for implementation in the first phase -
- Setting up of transfer stations across seven locations, each with two portable compactors
- Procurement of Hook Loaders with Prime Movers for haulage of compactors
- Procurement and introduction of Mechanized Road Sweepers
- Procurement and installation of Modular Bio-Gas units which can treat food waste at source across eight locations in the town
A medical effluent treatment plant with a capacity of 100 KL / day has also been set up for the treatment of effluent generated within the Tata Main hospital (TMH) in Jamshedpur.
