Kutch Copper Publishes First Sustainability Report, Plans to Double Output

Kutch Copper, a unit of Adani Enterprises, has published its first sustainability report for its Mundra refinery in Gujarat. The report sets out 115 MW of planned renewable power, reliance on nearly 100% desalinated water and treatment of 99.8% of sulphur emissions. It also outlines a US$1.2 billion plan to double capacity from 500,000 to 1 million tonnes per annum (tpa).

The report, covered on 11 October 2026 by the Economic Times via PTI, lands at a sensitive moment. India meets only about 35% of its refined copper demand from domestic production, which places a large share of its electrification ambitions on imported metal.

The open question is whether a fast-growing smelter can expand and decarbonise at the same time. Here is what the report commits to, what remains unverified, and what it signals for anyone tracking copper supply or ESG-linked metals projects.

What Kutch Copper says it has achieved, and what it has not yet proven

On paper, the environmental numbers are strong. The company reports the following, all self-reported:

• Nearly 100% desalinated water use across operations
• A zero liquid discharge approach, meaning process water is treated and reused rather than released
• 99.8% of sulphur emissions treated
• Community investment in healthcare, education and livelihoods

Sulphur treatment: 99.8% Company-reported figure; no independent verification found.

The renewable plan needs a sharper reading. The 115 MW is a commitment, not an operating asset, and no completion date has been given.

That is the gap. No third-party verification, regulator audit or peer-reviewed assessment of these figures has been found. The wider Adani Group portfolio has drawn ESG scrutiny, yet no post-2024 independent assessment specific to the Mundra refinery has surfaced. The company has also disclosed nameplate capacity (the maximum the plant is designed to produce), not its latest realised output.

Reported Adani copper plant problems around feedstock availability and ramp-up pace show why the gap between nameplate capacity and realised output matters when assessing any expansion plan.

For you, these are claims to monitor rather than benchmarks to rely on. External assurance in later reports is the signal worth waiting for.

How decarbonised smelting works

Four levers cut a smelter’s environmental footprint. Renewable power reduces emissions from electricity use, which maps to the 115 MW plan. Sulphur capture converts sulphur dioxide into saleable sulphuric acid instead of releasing it, which is where the 99.8% figure sits. Desalinated, closed-loop water reduces freshwater draw. Process efficiency lowers energy use per tonne.

Comparable decarbonisation data for Hindalco, Glencore, Codelco or Chinese smelters was not found, so no like-for-like ranking is possible.

Why doubling to 1 million tonnes matters for India’s import problem

India’s copper gap is large and widening. NITI Aayog’s Trade Watch Quarterly, released on 16 September 2026, shows copper’s share of India’s metal imports jumped from 12.4% to 23.1%.

India’s copper market transformation is being driven by the widening gap between domestic refining and demand, which leaves a large share of electrification plans dependent on imported metal.

India became a net importer after Vedanta’s Sterlite smelter at Thoothukudi closed. The expansion targets that hole: US$1.2 billion to reach 1 million tpa, which the company says would create the world’s largest single-location custom smelter, with Adani materials pointing to around 2030.

Policy is pushing the same way. The National Critical Minerals Mission, launched through the Union Budget 2024 and aligned with India’s net-zero 2070 target, backs domestic processing, and IEEFA cites Kutch Copper as a recently commissioned project expanding local refining.

Several details remain undisclosed:

• Phase-by-phase expansion timeline
• Funding mix across equity, debt and internal accruals
• Latest realised annual output

Domestic refining is policy-backed and structurally needed. The expansion’s returns, though, depend on details the company has not yet published.

The squeeze ahead: global demand, tight concentrate and what could go wrong

Beyond Mundra, the demand picture looks favourable. Wood Mackenzie forecasts global copper demand rising 24% by 2035 to about 42.7 Mtpa.

New supply needed by 2035: 7.8 Mt Wood Mackenzie estimate

Supply growth looks thinner. The International Copper Study Group (ICSG) forecast refined production growth of about 3.4% in 2025 and just 0.9% in 2026.

That is where the margin risk sits. Smelters earn treatment and refining charges (TC/RCs), the fees miners pay to have concentrate processed into metal. When smelting capacity grows faster than mine supply, smelters compete for ore and those fees tend to fall. No current TC/RC benchmarks or LME price data were found, so the risk is directional only.

Outcomes of annual treatment charge negotiations between miners and Asian smelters set the tone for refining margins, and they are the benchmark any new custom smelter will be measured against.

Sustainability still carries commercial weight. The International Energy Agency’s Copper Analysis of 12 August 2026 stressed lower emissions intensity among major refiners. IEEFA has warned about import-bill volatility, and NITI notes projects must be competitive to lift self-sufficiency.

Strong demand is necessary but not sufficient. Three variables to watch:

• Concentrate supply availability
• TC/RC movements
• Independent verification of environmental claims

What the report settles, and what investors still need to see

The maiden report establishes intent and scale: a decarbonisation plan, strong reported environmental metrics and a funded ambition to double capacity. What it does not settle is verification, timing or financing.

The forward watchlist is specific: independent assurance of the water and sulphur figures, a completion date for the 115 MW, phasing and funding for the expansion, and the direction of TC/RCs. If you follow copper supply or ESG-linked metals projects, those four markers will show whether the Mundra story moves from claim to proof.
