Chapter 05 of 5
The Infinite Loop
The physics of recycling and the metal's modern ubiquitous life.
- Atomic Identity
The Immortal Element
Unlike plastics that degrade when melted, aluminium atoms remain unchanged by the recycling process. It can be melted and reformed infinitely without any loss of its physical properties.
- Energy Economics
Frozen Electricity
Creating primary aluminium from ore requires massive electrical currents. Recycling it bypasses this electrolysis, consuming only 5% of the energy needed for new production.
- Resource Legacy
A Living Inventory
Because of its durability and value, roughly 75% of all aluminium ever produced in human history is still in productive use today. It is a permanent global stock.
