from Hindalco. Continuous upgrades and process
improvement enable it to keep pace with the
demands of its ever-growing markets.

Aluminium recycling
has
been a common practice
since the early 1900s. The process
does not damage
the metal's structure.
Recycling aluminium cans,
foil and foil containers helps
in conserving energy. |
