Gerenciamento dos resíduos de pescado: uma revisão integrativa sobre as feiras livres brasileiras

Abstract

Lack of proper waste management causes a great deal of social, economic and environmental damage. These problems are usually easy to see in places with constant waste generation, such as Brazilian open-air markets. The fishing sector produces large volumes of waste every day as a result of fish processing. The aim of this research is to identify and understand the management of fish waste at the main open-air markets in Brazil, as well as to draw up a protocol for the proper management of fish waste at open-air markets. This is an integrative literature review, based on the analysis of papers published between 2014 and 2024, which enables the synthesis and analysis of the knowledge already produced on the subject. The results of this research revealed flaws in waste management, as well as the lack of waste separation, the absence of effective measures for temporary storage and inadequate final disposal, much of which is disposed of in landfills. The management diagnosis allows the processes and opportunities for improvement to be identified, understanding the current difficulties in the methods, allowing the development of alternatives for using this waste, transforming it into high-value by-products such as the production of flour, oils, feed, composting, fertilizer production, the use of biodigesters and the production of gas for energy use, leather, handicrafts and others. Adequate waste management can help provide appropriate solutions to minimize environmental and social problems caused by the large amount of waste generated, as well as providing sustainable alternatives for proper treatment, including recycling and reusing this waste to produce new products.
