Angola makes new steel from old guns

(CNN)The remnants of Angola's brutal 27-year civil war are still littered around the capital city Luanda, in rusting piles of decommissioned tanks and weaponry.

The instruments of death are now being pressed back into use, but this time for a more productive purpose.
War scrap will provide the primary resource material for Angola's first steel mill - the largest in West and Central Africa - which recently started operations at the $300 million Aceria de Angola facility, 40 kilometers north of Luanda.
