Located next to the terminal, on a remaining strip of the Atlantic Forest, the Green Belt, which has an area of 70 thousand square meters, was acquired in 2002 by Transpetro. For the recovery of degraded areas, the company planted about 4,000 native species.
The Green Belt of the São Francisco do Sul Terminal has a forest nursery, nature trails, a reception house, a library with publications on environmental education, and an ecological museum. The project maintains a program aimed at students of primary and secondary education, with lessons about the environment. The site also has a greenhouse for the production of seedlings for the Green Belt, the community, and visitors.
