It is estimated that 75 to 199 million tonnes of plastic is currently found in our oceans. Unless we implement drastical changes in our approach to plastic production, usage and disposal, the amount of plastic waste entering aquatic ecosystems could nearly triple from 9-14 million tonnes per year in 2016 to a projected 23-37 million tonnes per year by 2040. How does it get there? A lot of it comes from the world's rivers, which serve as direct conduits of trash into lakes, seas, and the ocean.

Plastic and impacts on marine ecosystems

Ingestion, physical entanglement, smothering, and the transport of pathogens in biofilms are causing a range of lethal and non-lethal effects in marine organisms, including physiological disturbances, disease, changes in gene expression, alterations of behaviour, and shifts in species assemblages and biodiversity. These in turn, have impacts on ecosystems, leading to a wide range of social and economic consequences such as loss of revenue from natural resources and damage to maritime industries and coastal infrastructure.

Marine microplastics: example of plastic impact on marine environment

Plastic pollution has led (among other things) to microplastic contamination of the whole marine environment, from the shore to the deepest ocean sediments (e.g. Ryan et al. 2009; Woodall et al. 2014). These microplastic particles can adsorb and transport contaminants from the surrounding environment, adding to the many chemical additives that are incorporated during the production of the plastic. Marine organisms can ingest this plastic directly, or by consuming other organisms that contain plastic.

How CCB is working on plastic?

CCB and its member organizations have been working for many years to address the issue of plastic pollution in the Baltic Sea region in frame of it Hazardous Substances and Marine Litter Working area. Examples of our activities include the projects Plastic Free Baltic, Plastic Free Ocean, and the “#NonHazPlasticDiet” campaign.

Our current thematic plastic engagements include CCB participation in the EU Interreg project “Baltic Approaches to Handling Plastic Pollution under a Circular Economy Context” - BALTIPLAST (2023-2025). The project aims at the prevention and reduction of plastic waste in the Baltic Sea Region, focusing on single use plastic reduction, improvements in plastic packaging and innovative collection and treatment systems at the municipality level.

Soon this year, CCB will release the new report "Keep Fibers Zipped", which will cover available solutions to tackle microfiber pollution from textile in the Baltic Sea region, and globally.
