LA OROYA - CAPITAL METALÚRGICA DEL PERU Y DE SÚR AMÉRICA

1. The Industrial Boom and the Metallurgical Complex At the beginning of the 20th century, the American company Cerro de Pasco Copper Corporation chose this strategic location to build one of the largest metallurgical complexes in the world. Inaugurated in 1922, the complex was designed to process copper, lead, zinc, and precious metal concentrates from nearby mines. For decades, La Oroya was the economic engine of the Junín region, attracting thousands of workers and becoming a vital hub connecting Lima with the center of the country (the Central Highway and the Central Railway). 2. The Environmental Impact and Health Despite its economic importance, the city gained worldwide notoriety for critical reasons. The lack of environmental controls for much of the 20th century led to severe heavy metal contamination (especially lead, arsenic, and cadmium). Critical Point: In 2007, the Blacksmith Institute included La Oroya on its list of the 10 most polluted places on the planet. Public Health: Studies detected blood lead levels in children that far exceeded WHO limits, leading to a long-standing public health crisis. 3. Crisis, Nationalization, and Bankruptcy The plant's history has been marked by constant changes in ownership and legal conflicts: Centromin Perú: In 1974, the complex was nationalized. Doe Run Peru: In 1997, it was privatized and acquired by this US company, which eventually faced financial and environmental problems, suspending operations in 2009. 4. Current Situation: The Workers' Rebirth After years of paralysis and liquidation processes, 2023 marked a historic milestone: the company's former workers, organized as Metalurgia Business Peru (MBP), took control of the plant after receiving it as payment for their outstanding wages. Today, La Oroya seeks to reinvent itself under a new management that promises to be more environmentally responsible, attempting to balance its mining identity with the right to clean air.
