The biodegradability of Walki’s Bioska films are among the fastest on the market. The Finnish environment Institute has conducted studies to measure the biodegradability of bio-based and biodegradable plastics. Walki Plastiroll´s Bioska films were one of those plastics that had the fastest biodegradability.
Biodegradable plastics material is considered a vital solution in the fight against plastic trash in our oceans, but there has been little research on how biodegradable packaging materials actually behave in marine conditions.
Within the year-long Ubinam project, SYKE studied a variety of different biodegradable films and materials both in field and laboratory tests. Within these studies, SYKE investigated Walki’s new transparent packaging films called Bioska 501 and Bioska+. Samples of the material were placed in the Baltic Sea on the southwest coast of Finland for 6 respectively 12 months. The study found that the Bioska films had the fastest biodegradability: there was nothing left of the materials already after 6 months.
A further laboratory test confirmed the results. The same materials were studied in a one-month long laboratory trial. The findings were in line with the sea tests: the materials biodegraded rapidly.
“These results are very encouraging as EU is challenging conventional plastic with several new directives, including plastic product bans, some coming into force already 2020 Jani Avellan, R&D Director, Innovations.
“We are well prepared to help our customers chose more sustainable alternatives. Our Bioska 501 and Bioska+ films are based on natural polymers by plants and bacteria. The fact that the material is also very thin contributes to their fast biodegradability”, concludes Avellan.
