Guilan Ports and Maritime Administration, located in Anzali Port, Guilan Province, Southwest Iran is one of the most important and active ports of the southern part of the Caspian Sea. The aim of this study is to assess the current state of hazardous and non-hazardous waste management in Anzali Port and provide practical solutions. The study performed from July 2017 to June 2018, to quantify and classify waste generated from various operations, including loading and unloading, repairs, and construction activities. Shapiro-Wilk test was performed to evaluate the normal distribution of data, and the One-Way ANOVA and Tukey tests were used to examine significant differences. The total waste generated was 3,082.200 tons year-1, consisting primarily of wood waste (2,544 tons year-1), steel scrap (344.97 tons year-1), and unusable tires (368.25 tons year-1). The hazardous wastes were categorized based on its characteristics such as toxicity, corrosiveness, flammability, and reactivity, in line with the Basel Convention and the Resource Conservation and Recovery Act (RCRA). Approximately 4% of the waste was classified as hazardous. The findings showed that effective waste management practices could result in the recycling and reuse of approximately 96% of the generated waste, leaving only 4% to be disposed. This study also analyzed the efficiency of current waste management strategies in the port, including waste segregation at the source, recycling, reuse, and the sale of certain waste materials such as metal scrap and used tires. Based on the findings, several recommendations for improving waste management were proposed, including the establishment of dedicated storage facilities for hazardous waste, enhanced waste segregation at the source, and the implementation of staff training programs. The results highlight the importance of adopting a more comprehensive and sustainable waste management strategy to reduce environmental impact and improve resource recovery.
