Salt wells closure is monitored by authorities

The extraction of rock salt in Maceió was completely halted in May 2019, and Braskem has been taking measures for the definitive closure of the salt wells, according to the plan presented to the authorities and approved by the Brazilian National Mining Agency (ANM). Completion of the work is scheduled for mid 2026.

Studies conducted by national and international institutes showed the appropriate technique to be applied to each of the 35 salt wells.

The operational areas encompassing the 35 salt wells are technically monitored using high-tech instruments to ensure the safety of the surrounding area and the evacuation and monitoring phases.
