Baise Guangxi aluminium plant

Baise Guangxi aluminium plant is an aluminium smelter in China with a reported capacity of 320,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by Guangxi Baise Mining Aluminium Co Ltd. By capacity it ranks #80 of 141 aluminium smelters tracked in China. It emits about 680,044 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 158,518 cars.

У контексті: як порівнюється це підприємство

При потужності 320,000 t of alumina/aluminum Baise Guangxi aluminium plant — це приблизно медіана aluminium smelter у China (372,000 t of alumina/aluminum). Його викидання CO₂ на одиницю потужності приблизно на 16% вище медіани aluminium smelter. Підсектор: aluminum. Як aluminium smelter, воно вимагає високотемпературного технологічного тепла (зазвичай 600–900°C) для основних промислових операцій — тепла, яке повинне подаватися котлами, печами або прямим спаленням, і втрати через неізольовані судини та трубопроводи представляють витрачене напразно паливо. Знімна модульна теплоізоляція може зменшити ці втрати на 80–96%, охолодивши поверхню обладнання до ≤45°C, з окупністю часто менше 2 років. Алюмінієві плавильні використовують великі електричні струми для рафінування глинозему в розплавлений алюміній вище 900°C, і розплавлений метал повинен текти через тиглі та ливарне обладнання.

Порівняння продуктивності та інтенсивності CO₂ розраховано на основі даних промислових об'єктів Climate TRACE; роль сектору заснована на інженерних довідниках.

Heat loss & insulation profile

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.

Indicative recoverable energy

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 2,200 MWh/yr (≈ 450 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.

Safety & the no-regret first step

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.

External climate finance your country can access

Domestic energy-efficiency grants are limited here; industrial decarbonisation is mainly funded externally:

• Japan JCM (Joint Crediting Mechanism) — Japan co-finances diffusion of decarbonising tech incl. INDUSTRIAL ENERGY EFFICIENCY in partner countries, in exchange for carbon credits. Channels: MOEJ model projects, ADB trust funds, NEDO demonstrations.
• UK International Climate Finance (ICF / ODA) — ~GBP 6bn ODA over 3 yrs; industrial-decarbonisation flows via Climate Investment Funds (CIF) - Clean Technology Fund.
• Green Climate Fund (GCF) + ADB / World Bank / UNIDO — Concessional finance & grants for industrial energy efficiency. E.g. GCF $200M ADB-led India Green Finance Facility; World Bank FP071 'Scaling Up Energy Efficiency for Industrial Enterprises in Vietnam'; ASEAN ACGF energy-efficiency revolving funds incl. SMEs.

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.
