У контексті: як порівнюється це підприємство

При потужності 330,000 t of alumina/aluminum Tiwai Point aluminium plant — це приблизно медіана aluminium smelter у New Zealand (330,000 t of alumina/aluminum). 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.
