Sustainable Rope

Marlow and LIROS Ropes have been developing more environmentally friendly alternatives to their existing range, which is predominantly manufactured from petroleum-based plastics.

Yachting rope produced from sustainable materials such as recycled plastics (rPET) and bio-based Dyneema® is becoming more widely available.

Here at Jimmy Green Marine, we are proud to support companies that are committed to cleaning up their manufacturing operations by, e.g. optimising energy usage, optimising their fibre sourcing and reusing or recycling their waste.

Green Wave

LIROS Ropes' has also launched a ‘Green Wave’ initiative - a corporate philosophy that not only promotes sustainability in every aspect of their production but also fair, environmentally conscious management of their workforce.

LIROS Green Wave 3 Strand Recycled Polyester Mooring and General Purpose Yachting Line has been developed by LIROS Ropes in partnership with Jimmy Green Marine.

LIROS Green Wave 3 Strand Recycled Polyester is manufactured from rPet recycled plastic by LIROS Ropes exclusively for Jimmy Green Marine.

LIROS Green Wave 3 Strand Polyester compares favourably in performance with other three-strand polyesters including strength and handling, making it eminently suitable for Mooring Lines.


Marlow bring together all their eco-conscious development under one BLUE OCEAN® brand.

Marlow BLUE OCEAN® reduces the reliance on fossil fuels by using fibres manufactured from either waste plastic or natural sources for yachting and boating.

The Marlow BLUE OCEAN® brand is their mark of sustainability assurance and on-going commitment to conduct all operations within an environmentally conscious framework.


Marlow BLUE OCEAN® yarn is GRS certified and manufactured from 100% recycled waste plastic bottles collected from disposal units.

The bottles are manufactured into recycled polyester (rPET) to produce a yarn which has the same specifications and technical characteristics as polyester yarn manufactured using virgin feedstock.

Marlow Blue Ocean Logo

BLUE OCEAN® yarn can be recycled again at the end of its life, therefore aiding a circular economy, as long as it has not been mixed with any other chemicals or fibre materials.

Yachting with BLUE OCEAN®

Since the launch of the award-winning BLUE OCEAN® DOCKLINE in 2018, Marlow have been working hard to innovate, develop and educate the global sailing community about the materials they use in their rope-making to achieve the best quality and performance.

Marlow are the first rope-maker in the Leisure Marine industry to introduce rope products made from recycled and sustainably sourced materials that don't compromise on performance.


ISCC certified, Bio-based Dyneema®

LIROS Ropes and Marlow have introduced Bio-based Dyneema for parts of their performance ranges. The carbon footprint of bio-based Dyneema is nearly 90% lower than generic Dyneema due to sustainable and renewable sourcing. This is a huge gain with no change to the manufacturing process or detriment to the quality and performance of the yarn.
