Yarn Production from the Offshore Industry Mooring rope Waste: A Circular Textile Economy Opportunity.

Offshore platform decommissioning is a complex process that can cause marine damage. The circular economy can be used to implement sustainable initiatives in the decommissioning process. Mooring ropes, which commonly consist of poly(ethylene terephthalate) (PET) fiber, are one type of waste generated during offshore platform decommissioning. This study aims to demonstrate that the ring spinning process is a sustainable solution to recycling PET fibers from post-industrial mooring ropes (PMR-PET) by producing yarns containing 70–60% PMR-PET. One-way ANOVA and the Cochran test demonstrated that the yarns made with PMR-PET exhibit better tensile properties than those made with 100% commercial PET. Addition of PMR-PET produces a yarn with a higher crystallinity. The lower degradation temperatures of PMR-PET yarns are not enough to limit their use in textile products. This study demonstrates that recycling PMR-PET provides an opportunity to promote the circular economy and develop new yarns in the textile industry. [ABSTRACT FROM AUTHOR]
