Biomassa da carcinicultura para a produção de biogás no litoral cearense

Abstract

Shrimp farming is the fastest growing segment of aquaculture in the world and a booming activity in the State of Ceará. The production process causes environmental problems because it generates large amounts of waste at all stages of the production chain, from the larvae to the processing of adult shrimp in the processing industries. The objective of this work was to analyze shrimp biomass for the production of biogas in the coast of Ceará. According to the secondary data obtained in the literature, shrimp biomass has a biogas production potential of 25 m³ for each ton of shrimp waste, making it possible to produce 1 million of m³ of biogas annually in the State, a representative potential for generation of electric, thermal or vehicular energy. This energy can be used in the farms themselves for pumping, aeration of tanks and cold rooms. The use of shrimp biomass for the production of biogas needs to be encouraged in order to minimize its environmental impact and promote the conversion of the generated waste into useful energy.
