Imaribo Group’s project to engage in the pulp and paper industry was consolidated in the 1980’s. The Group ’s first facilities, which gave birth to Iguaçu Celulose, started operations in the early 1970’s.

The starting point was the purchase, in 1971, of Celupel S.A industrial facility, which produced mechanical pulp and cardboard in the city of Curitibanos, Santa Catarina State. In the following year the Group bought the industrial unit in Campos Novos, also in Santa Catarina State, where it started producing duplex cardboard due to its higher profitability.

In 1978, the Group invested in new machinery for the Ibicuí (Campos Novos) unit to produce up to 50 tons of paper per day. In the same period and to meet the needs of supermarkets and other retailers, it started producing Kraft paper in this unit.

Purchasing Grupo Lupion’s companies in the early 1980’s was decisive for Imaribo Group consolidation in the paper and pulp segment. Lupion’s Indústria Papeleira Santa Mônica in São José dos Pinhais, Paraná State had two machines, one for duplex cardboard and the other for special paper.

In 1980, the Group also purchased Indústria Papeleira Piraiense, a pulp producer in Piraí do Sul, Paraná State. The acquisition of these facilities triggered a restructuring process and strengthened Imaribo Group paper production, leading to the adoption, in 1984,of one single trade name: Iguaçu Celulose, Papel S.A.

In 1993, production was verticalized in Campos Novos facility after purchase of equipment to produce pasted valve multiwall paper sacks.
