Replanting in the mined-out areas starts right after bauxite is extracted. The entire replanting process is monitored by a method developed at MRN and approved by environmental agencies. The survival rate of the plant species used in the replanted areas is 90%.

Over the past 41 years, we have rehabilitated 7,398.18 hectares, where more than 14.5 million seedlings of 450 native tree species have been planted.


In 2019, our forest nursery produced 689,103 native seedlings of 80 species of the Amazon biome. Only seeds acquired from neighboring traditional, riverside and Quilombola communities were used.
