I-Coats' SDG's

Bio-based Coatings and Life-Cycle Management, Climate Change, Sustainability, Lifecycle Assessment and Coatings:
what to do?

Today we are clearly observing more and more the impact of man on the environment and what our dependence on fossil-based product is doing to our planet. More and more is known about (micro-)plastics and their impact on life.

As the hazards are identified in more detail it can be expected that regulations will follow. A good example of this are the sustainability guidelines that Europe published at the end of 2024 for fishing and aquaculture.

I-Coats coatings are an integral part of the rope or net and as such we also need to prepare!

Fortunately the choice in bio-based alternatives is increasing, allowing a higher bio-based content, whilst still having a good performance.

I-Coats has taken the next step to increase the bio-based content with the purpose to reduce environmental impact and dependence on finite fossil fuel.

Increasing the bio-based content to a significant amount (>30% - 50%) has a positive influence on bio-degradation.

In our view bio-degradation is the best solution against the persistence of micro-plastics.

Components should only be called bio-based, when they are from sustainable sources. This approach is getting more and more accepted, resulting in more bio-based products from sources with a shorter cycle. With these products come different processing routes that are more environmentally friendly (enzymatic).

Definitions for sustainable, bio-based and relevant types of bio-degradation for coatings are briefly mentioned.

Then an overview for the different bio-based coatings as supplied by I-Coats, lastly expected developments in sustainability are discussed.

 

In the Glaukos Project research partners, together with I-Coats, have addressed evaluation of biodegradation by developing and adapting screening methods.

The goal of these tests is to identify the following issues in an acceptable time:

  • Does the plastic degrade?
  • When does it no longer pose a threat to marine life (ghost nets)?
  • Does the degradation release toxic products (see also schematic)?

Work has started to evaluate if our bio-based coatings are also marine-friendly.

Initial results suggest that with a higher-bio-based content the coatings are also more marine friendly.

To evaluate the performance of its coatings on fibres and ropes for the different applications I-Coats NV is using different tests.

These tests were selected on our best understanding of the conditions of use for a given application and are scaled down for more efficient testing.

Lab tests can be used for a relative comparison against known performance of a given product in use. Actual performance should always be verified in use.

For abrasion testing a special machine is used that can abrade a rope against a hexagonal bar.

A standard 3 mm HMPE rope has been coated with the coatings mentioned below and the abrasion performance compared to our standard equivalents:

  • ICO-THANE 10 ECO is a soft, flexible, light-fast polyester-based aqueous aliphatic polyurethane dispersion which contains about 45% bio plastics
  • ICO-THANE 32 ECO is a medium-soft flexible, light-fast polyester-based aqueous aliphatic polyurethane dispersion compound which contains about 50% bio plastics
The performance of the ECO variants is comparable or better than that of the regular products (pick-up is given as % in the graph).
Because of their basis and their expected marine-friendly performance they are an important step towards meeting the sustainability goals.

Today there are basically two approaches:

  • Life Cycle Assessment (LCA). Here the entire life cycle is analyzed: all relevant phases such as extraction of raw materials, transport routes, manufacturing processes and disposal. With focus on the environment impact. Often it is referred to as carbon foot printing, as the focus is specifically placed on the greenhouse gas emissions generated.
  • Sustainable Development Goals (SDG’s). They were adopted by the United Nations in 2015 as a universal call to action to end poverty, protect the planet, and ensure that by 2030 all people enjoy peace and prosperity. The SDG’s highlight the connections between the environmental, social and economic aspects of sustainable development.

Both methods have advantages and disadvantages. However for ropes and nets focus within the EU is more on sustainability.

For this reason I-Coats has decided to work with the SDG approach.

See below, for our contribution to these goals:


Conclusions

I-Coats has developed two new bio-based coatings ICO-THANE 10 ECO and ICO-THANE 32 ECO with 45% resp 50% bio-based materials.

In the tests at I-Coats the ECO variants showed a slightly better performance in abrasion than our regular products.

These coatings help us to contribute positively to the sustainability goals relevant for coating.
