Degradation of new biodegradable plastic materials in the Baltic Sea marine environment and assessment of associated environmental risk (UBINAM)

Government_key_projects_logo

Plastic litter pollution of marine environments is a widely recognized environmental problem. The plastic pollution ultimately stems from extensive and ever-increasing use of plastic materials and their unintentional transport to the environment. Plastic packaging from consumer products is one of the prevalent sources of marine plastic litter.

Bio-based and biodegradable materials as substitutes for petrochemical plastic materials have been presented as one solution for marine litter problem. These biomaterials are also central in on-going transition towards bio- and circular economies. The current extent of bio-based and biodegradable materials use is however not known nor their real degradation rates in the marine environment.

SYKE Marine Research Centre and Centre for Sustainable Production and Consumption are responsible for project realization. The project has three commercial partners; Plastiroll, Sulapac and Paptic. Biodegradation of novel bio-based and biodegradable materials produced by partner companies will be studied in laboratory and in the marine environment. Also, common commercially available bio-based and biodegradable materials used in consumer product packaging will be studied.

Only some biodegradable plastics actually decompose rapidly in the Baltic Sea 2019-11-14
The Finnish Environment Institute has studied how biodegradable and bio-based materials actually decompose in the Baltic Sea marine environment. A set of tests in the sea revealed that some materials decomposed almost completely within six months, while others decomposed not very much at all in the course of the entire year.
