Paulínia

Machine translation of the Portuguese Wikipedia article (November 2026 version).

Paulínia is a Brazilian municipality in the interior of the state of São Paulo. Located in the northwest of the São Paulo Macrometropolis, it lies about 119 km from the state capital, covers an area of 139 km² and, according to the 2022 IBGE census, had a population of 110,537 inhabitants. It was emancipated on 28 February 1964, although its foundation dates back to the early 20th century. The name honours José Paulino Nogueira, a landowner known in the Campinas region, the municipality from which Paulínia separated; the railway station around which the municipality developed was also named after him. It lies on the Rio–São Paulo axis, serving as a link between Greater São Paulo and cities in the region such as Cosmópolis, Artur Nogueira and Conchal.

It is known for hosting one of the largest petrochemical hubs in Latin America, centred on the Paulínia Refinery (Replan). Thanks to Replan and the petrochemical hub, which are based in the northern part of the city, Paulínia has the seventh highest per capita income in Brazil. The hub also causes high levels of ozone pollution, especially in the Betel district and in the Replan area, where companies such as Rhodia, Purina, Shell, Syngenta and Petrobras are located. The city stands out for intense population growth, the largest in the Campinas Metropolitan Region. The service sector has historically been of little importance to the municipality, but it has recently been developing thanks to projects such as Paulínia Magia do Cinema.
