1. Introduction
Biodegradable Vaisala BioTwine™
Vaisala BioTwine™ is biodegradable twine that reduces micro-plastics originating from soundings operations after service.
Vaisala BioTwine™ is a cellulose-based fiber. The material is biodegradable and compostable. In biodegradation, oxidation and hydrolysis start breaking the polymer chains of the Vaisala BioTwine™, which then changes to enzymatic cleaving by different microorganisms. The resulting small sugar molecules are then used in the microorganisms’ metabolism. No micro-plastics are formed during the degradation. In manufacturing, the fibers are produced in a closed process where 99% of organic solvent can be recovered and reused.
