Grey waters in maritime traffic

Project to mitigate nutrient emissions from maritime traffic

Approximately 2000 ships sail the Baltic Sea daily, and 95 percent of these are freighters. Aboard these ships are total of 25000 crew members. Currently all grey waters and food waste from these ships can legally be unloaded into the Baltic Sea. Car ferries operating between Finland, Sweden and Estonia, scheduled cargo ships and other environmentally responsible actors already unload their waste on land. Despite this, significant amounts of food waste and grey waters are unloaded into the Baltic Sea from both cruise ships and freighters.

Grey waters in maritime traffic -project is initiated by the Baltic Sea Action Group to develop measures to mitigate emissions from maritime traffic. Grey waters and food waste are a source of excess nutrients, bacteria and microplastics in the sea. The goal of the project is to significantly increase the amount of waste unloaded on land, through voluntary action within the industry and improving instructions. Additionally, the goal is also to decrease food waste production through well-planned acquisition and better waste management. Constructive collaboration between the industry is an integral part of the project.
