Alternativa sustentável para descarte de resíduos de pescado em Fortaleza

Abstract

Population growth in urban centers has worsened the problem of management of solid waste generated by residents, caused mainly by the volume of waste produced and the consumer lifestyle. In this context waste recycling, whether agricultural or industrial origin, originating from diverse supply chains, whose improper disposal can cause negative impacts to the environment, such as waste from the fishing industry, presents itself as an important tool for minimize the deficit of organic fertilizers to ecological production systems. Thus, this study aimed to propose a sustainable alternative for disposal of fish waste generated from kiosks and beach huts in Fortaleza - Ceará, thus producing organic compost made from discarded material (viscera, head , spine and scales), thus adding, value to this waste, helping to break the dependence on chemical fertilizers by farmers and reducing the environmental impacts caused by its disposal in the city of Fortaleza. The chemical analysis of organic fertilizer from fish showed positive results, with rich Fe, Ca, P, K, Mg, Mn and N, claiming that this organic compound is an excellent alternative to get good yields in agriculture.
