A explotação de algas calcárias: uma fronteira na mineração brasileira

Abstract

This study had the general objective of analyzing the Brazilian norms regarding the exploitation/exploitation of calcareous algae. It is intended to demonstrate, then, the vulnerabilities of the national legislation, besides suggesting modifications. Regarding the methodology, we opted for an exploratory, bibliographic research, where the data were interpretedin a qualitative way. The conclusion reached supports that theBrazilian marine environment needs to be updated inthe regulatory level. Studies on the environmental impacts on the exploitation of calcareous algae are almost non-existent in the literature. Commercially, calcareous algae have been a major attraction for their properties,and the lack of a specific standardization makes the exploitation occur in a disorderly way. Environmental impacts are not being evaluated and the damage to the marine environment can be irreversible. The norms to regulate the exploitation need to be clear and directed, so that the whole process is carried out in a licensable, observable, adjustable and mainly auditable way.
