Vedanta Moves Madras HC Against TNPCB Order: A Legal Battle Over the Future of “Green Copper

Vedanta Sterlite Copper plant continues to remain in discussions since long. Years after the plant’s dramatic shutdown in 2018, the debate has returned once again- this time to the courtrooms of the Madras High Court.

Recently, Vedanta Limited has challenged a recent order of the Tamil Nadu Pollution Control Board (TNPCB) which rejected halted its proposal to establish a new “Green Copper” facility at the Thoothukudi site. The matter came up before the First Bench consisting of Chief Justice MM Shrivastava and Justice G Arul Murugan. Post preliminary hearing, the Bench ordered notice to the Tamil Nadu government and the TNPCB and posted the case for further hearing on February 26. 

The move is one of the important developments in India’s most closely watched industrial and environmental disputes. But this time, the demand is not only about reopening Vedanta Sterlite copper plant, but it is about building something fundamentally different.

From Shutdown to Reopening

When operational, the Sterlite Copper plant was one of the major contributors to India’s copper production (which is also a critical mineral), meeting almost 40% of the country’s copper demand. Its closure in 2018 followed widespread Vedanta protests over alleged environmental violations, prompting the Tamil Nadu government to order a permanent shutdown.

Since then, the site has remained closed. For some, it’s a matter related to environmental concerns. For others, particularly sections of the local business ecosystem, it means lost jobs, stalled livelihoods, and economic disruption. 

Vedanta’s latest proposal seeks to change the narrative. The company has applied to establish a “Green Copper” facility, built around cleaner technologies, lower emissions, improved water management, and the integration of recycled copper into production.

According to Vedanta, the new model combines primary copper production with recycled inputs, backed by upgraded pollution-control systems and sustainability-focused processes.

Allegation of Procedural Violations

In its petition, Vedanta has mentioned that the TNPCB’s order is legally unsustainable as it violates the principles of natural justice. The company also mentioned that the decision to reject its proposal was made without prior notice and without affording it a personal hearing.

According to Vedanta, such procedural safeguards are not optional but mandatory under statutory guidelines. The company specifically cited Rule 6(3) of the Control of Air Pollution (Grant, Refusal or Cancellation of Consent) Guidelines, 2025, which mandates the issuance of prior notice before inspection.

Vedanta stated that the inspection preceding the rejection was done without giving any advance notice to the company. An inspection carried out without following due process, is completely unlawful and against ethics.

On these grounds alone, the company has submitted that the TNPCB order warrants judicial interference.

What Is the Vedanta’s Green Copper Proposal?

Vedanta has suggested a green start proposal, the new proposal representing a comprehensive technological overhaul of the earlier plant. The company stated that under the “Green Copper” process, the company will deploy advanced pollution-control systems, digital monitoring mechanisms, and best-available global technologies to ensure environmental and public health safeguards.

The company mentioned that copper is an important strategic resource, both nationally and globally. To meet the rising demand from renewable energy infrastructure, electric vehicles, and electronics manufacturing, copper is essential to industrial growth and energy transition goals.

To meet the domestic copper demand, industrial units like the Vedanta Sterlite Copper plant play an important role. Strengthening domestic copper production through a modern, sustainability-focused facility would serve both national and state interests, while also generating employment and economic activity.

A Debate Bigger Than One Plant

What makes this case particularly compelling is that it is no longer just about a factory.

It is about:

• Whether industrial sites can be redesigned with improved environmental safeguards.

• Whether regulatory decisions should allow fresh technical evaluations.

• How India balances economic ambition with environmental responsibility.

And the Vedanta Thoothukudi plant, which was closed, can be rebuilt through transparency and compliance.

For residents of Thoothukudi, memories of Vedanta protests and environmental concerns have faded. What matters the most to them is how the closure has impacted their livelihoods and affected direct and indirect jobs.

What Happens Next?

As the matter proceeds in the Madras High Court, key questions will likely revolve around procedural fairness, environmental safeguards, and whether an independent technical review is warranted. Vedanta sought a direction to the authorities to establish a court-monitored multi-disciplinary expert committee consisting of representatives of TNPCB, Ministry of Environment and Forest, Central Pollution Control Board and Ministry of Mines, along with independent experts in relevant fields, to scientifically, independently and comprehensively examine the petitioner’s “Green Copper” proposal and submit a report.

So for now, the Vedanta Sterlite copper debate has moved from protest grounds to legal arguments.
