Tilapia is reported as the most cultivated fish in Brazil, representing 38% of national production. The leading tilapia producer in the country is Ceara. One of the problems in the cultivation of tilapia is the management of large quantities of discarded fish entrails, which until recently, did not have any use for the producers. Residual fish oils in the tilapia entrails are potential feedstocks for biodiesel production. With this in mind, the Ceara Nucleus Foundation of Industrial Technology (NUTEC) is "moving forward with a project that will transform it into a pioneer in the research of biodiesel production from tilapia entrails". Within the framework of this project, the Biodiesel Reference Laboratory (LARBIO) is in charge of gathering, storing and producing the biodiesel. According to LARBIO coordinator Jackson Malveira, the project was sent to the Northeast Bank of Brazil and it is in the evaluation phase..
