Item Acesso aberto (Open Access) Desafios para implantação dos protocolos estabelecidos no Padrão Global da Indústria para a Gestão de Rejeitos (GISTM), estudo de caso: estruturas de disposição de rejeitos no sudeste do Pará(Universidade Federal do Pará, 2025-04-25) SOUSA, Rodolfo Pereira; SILVA, Adriano Frutuoso da; http://lattes.cnpq.br/3321059172343690; https://orcid.org/0000-0003-1710-8862The creation of the Global Industry Standard on Tailings Management (GISTM) is a milestone for the world's largest mining companies, created with the aim of guaranteeing zero harm to communities and the environment This research aims to present the challenges of implementing the GISTM (Global Industry Standard on Tailings Management) for tailings disposal structures, located in the southeast of the state of Pará, being a dam, raised downstream, and a pit, which is an old mining area where the mineral reserve was exhausted in 2021. In order to assess the levels of compliance with the Global Standard, the technical collection of the tailings dam and pit was used to enable the application of the Compliance Protocols proposed by GISTM. The work presents the level of maturity in 3 stages, in the years 2023, 2024 and 2025. Although GISTM proposes requirements for an integrated analysis of tailings management, due to the different nature of the tailings disposal facilities, the facilities were evaluated in isolation. Based on the research, the dam was found to be more compliant with the items required by GISTM, with a more robust technical document framework than the pit. It is concluded that this result is correlated with the fact that the dam complies with Brazil's National Dam Safety Policy (PNSB), while the pit, as a tailings disposal structure, has no regulations for this use. In addition, it should be noted that although the pit is considered an unconventional disposal structure, the implementation of GISTM is required, subject to some adaptations in the understanding of what is proposed by the GISTM.
