Analytical Hierarchy Process (AHP), marine debris, plastic waste, plastic leakage interventionAbstract
Plastic wastes from ports may be leaked into oceans if it is not properly managed owing to its proximity to the sea, such as in the case of the port of Zamboanga in the Philippines - a government port with international standard certifications wherein plastic waste management remains a challenge to its management. This study aims to determine plastic leakage intervention options through the conduct of a Focus Group Discussion (FGD) and to propose the most preferred intervention using the Analytical Hierarchy Process (AHP) by incorporating the subjective judgment of different port key stakeholders and decision-makers. There were four criteria used for this AHP model to quantify the relative preference of each intervention namely environmental and health effectiveness (EHE), financial affordability (FA), implementability (IM), and social acceptability (SA). There were five (5) proposed possible management intervention alternatives, these are the memorandum order (MO) on proper waste segregation and collection, personnel training (PT) on plastic waste management, waste container labeling (WCL), provision of waste containers (PWC), procurement of garbage truck (GT), and establishment of a material recovery facility (MRF). The results of the AHP model suggest that most of the port’s key stakeholders and decision-makers prioritize the MRF and PT among other management interventions
