Aluminium SmelterIndiaCO₂ reported
Lanjigarh Alumina Refinery is an aluminium smelter in India with a reported capacity of 3,175,150 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. By capacity it ranks #1 of 20 aluminium smelters tracked in India. It emits about 6,635,219 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 1,546,671 cars.

在3,175,150 t of alumina/aluminum时，Lanjigarh Alumina Refinery是India中aluminium smelter的中位数远高于 360,000 t of alumina/aluminum。 子部门：aluminum。 作为aluminium smelter，它需要强烈的工艺热量（通常600–900°C）来进行其核心工业操作——必须通过锅炉、炉或直接燃烧供应的热量，通过未隔热的容器和管道的损失代表浪费的燃料。可拆卸模块化绝缘可以将这些损失减少80-96%，将表面冷却至≤45°C，投资回收期通常不到2年。 铝冶炼厂使用大电流将氧化铝精炼成900°C以上的熔融铝，热金属必须通过坩埚和铸造设备流动。

A aluminium smelter like this runs hot equipment that sheds heat continuously: alumina calciner, casthouse furnaces, hot ducting (electrolysis itself is electric) (surface/process temperatures around 150–1,000 °C). These surfaces lose energy to the air year-round; removable modular insulation cuts that loss, brings outer surfaces to ≤45 °C, and unclips for inspection.
electrolysis is mostly electricity (Scope 2) + anode process; on-site combustion small - insulation mainly relevant to alumina refining/casthouse.
On an already-insulated site (pipes & valves in cladding / jackets), closing the remaining gaps, flanges and damaged sections and switching to removable covers indicatively recovers about 4,200 MWh/yr (≈ 840 t CO₂/yr) — scaled to this site's reported CO₂ within its sector. Bare or damaged surfaces recover several times more.
See Inzonex insulation → Estimate your site →
Indicative, not a measurement. Conservative floor for an already-insulated plant; a TIPCHECK on-site audit gives a measured figure. Industry context: EiiF TIPCHECK — industrial insulation can save ~14 Mtoe/yr in EU, payback typically <2 years.
Bare hot surfaces here exceed the touch-safe limit (EN ISO 13732-1); insulation to ≤45 °C is a worker-safety and compliance win. And before electrification, fuel-switching or CCS, eliminating surface heat loss is the cheapest, fastest, lowest-risk step — audit the bare spots first, rip-and-replace later.
Domestic energy-efficiency grants are limited here; industrial decarbonisation is mainly funded externally:
CBAM. Exporters of cement, steel, aluminium, fertiliser, hydrogen and electricity to the EU face the Carbon Border Adjustment Mechanism — cutting embedded emissions (efficiency + insulation) lowers the levy.
Routed via national development banks / accredited entities — not a direct factory grant. Verified 2026.
