Waste oil management system from the maintenance of artisanal fishing craft the Peruvian case

The inadequate management and final disposal of lubrication oil waste from the maintenance of artisanal fishing vessel engines can affect the marine environment. In the Peruvian case, there is no evidence suggests that this waste is managed at all, and there is no regulation regarding this matter. Therefore, this study aims to implement an oil waste management system for artisanal fishing vessels in the Bay of Ancon in Lima, Peru. A collector prototype was installed according to oil waste generation estimates. Further, a management protocol was designed based on the provisions from Rule 38 of Appendix I of the MARPOL 73/78 Convention and the guidelines issued by the Peruvian Ministry of Transportation and Communications for the treatment of oil waste from merchant vessels. Before installing the prototype, there was no evidence of oil waste collection. During collection operations, in the stage before the installation of the collector prototype, 1795 L of waste oil was collected in 12 months. After the installation of the prototype, 3276 L of waste oil were collected in 11 months. According to our estimates, we collected 82.75% of oil waste produced by the entire artisanal fishing fleet in Bay of Ancon. This has been the first management system implemented in Peru, and for the first time, it has showed the final disposal of lubricating oils and other oil waste generated by artisanal fishing craft.
