Abstract: This paper analyzes the effectiveness of Directive (EU) 2019/883 from the social interest perspective. To achieve this aim, it assesses the performance of the sewage treatment plan (Annex IV of MARPOL) in Las Palmas Port and the accomplishment of the Cost Recovery System. This involves reviewing the mandatory fees for landing the sewage in the port, the sewage treatment costs and the environmental impact of the treated effluent from the vessels (environmental benefits) and addressing technical difficulties in order to meet the normative standard required from the vessels' sewage in the framework of Las Palmas Port. Through a cost-benefit analysis not only the current protocol for the reception and treatment of Annex IV waste in the port is assessed, but also alternative waste treatment plans (sewage routes) are discussed in terms of social interest. The results of the paper show that only when the treated sewage is reused are the costs assumed to implement the directive overtaken by the benefits gained from complying with it. Consequently, the port authorities should address their efforts in this direction, as should the policy makers, who should integrate in the international normative the collaboration of the on-board sewage treatment plants to meet the PPP (Polluter Pays Principle).
