IPCA (Piedmont Industry Aniline Colors) was founded in 1922: the factory has passed into history to a tragic story of environmental pollution and for many workers died of bladder cancer. In 1972 the two former workers, both suffering, lodge complaints against the factory. In 1977 after a long and tortuous process, holders and executives are convicted of manslaughter.
The IPCA finally closed in 1982: 168 workers died of bladder cancer. In 2005 a documentary film "Do not have to die to live" was made to tell of the terrible working conditions that factory workers were subjected. Today in the city of Ciriè there is an ECO-MUSEUM in memory of the workers.
