An analysis of the blackwater handling from a port perspective: The different aspects of methods, expenses, and challenges

Abstract

This report focuses on the handling of blackwater in two of Sweden's largest ports. The aim is to investigate the differences and similarities in blackwater management and identify any environmental characteristics that may differ. The results show significant differences in the number of visiting vessels, where passenger and cargo ships play a crucial role in blackwater reception. Introducing stricter legislation, such as requirements for ships to submit their blackwater in port, could reduce environmental damage. The report also highlights shortcomings in current legislation, which allows ships to discharge their blackwater into the seas, thus harming the environment. Limitations include only the two largest ports in Sweden and exclude technical and economic aspects. Two interviews with representatives were conducted to increase understanding for upcoming changes
