Aluminum smelting is the most electricity-intensive process in manufacturing. Producing one ton requires 14,000 kWh, enough to power an American home for 16 months. The Hall-Héroult process, invented in 1886, dissolves alumina in a bath of molten cryolite at 960°C and passes 1227 likes · 275 retweets · 57 replies · 2026-05-20T02:12:31.000Z Captured by scrape-follows from @Gaurab

The chemicals industry first punched a hole in the ozone layer and then fixed it.
