From research to reality:
Minimizing CO2
 impact while preserving oceans

A tremendous dilemma

Should we sacrifice
the atmosphere?

In the absence of proper protection, the underside of vessels is susceptible to significant marine biofouling. Heavy biofouling can result in a substantial increase in fuel consumption, up to 50%, leading to poor fuel efficiency and higher CO2 emissions.
The shipping industry accounts for nearly 3% of the world’s total CO2 emissions.

Or poison the sea?

The solution today is antifouling coatings. All cost-efficient coatings are toxic to marine organisms making up the fouling. Unfortunately, coatings contain toxic additives so-called biocides, which are released into the ocean contaminating marine life.
Annually, 15,000 tons of copper are discharged into the oceans due to antifouling coatings, equivalent to the weight of a blue whale.

EnCoat cuts the dilemma in half and lowers the cost

Traditional antifouling coatings often rely on excessive biocides to compensate for their tendency to leach into the sea before proper usage.
EnCoat’s technology, however, encapsulates the co-biocides, extending their antifouling effectiveness. This ultra-low-biocide innovative approach allows for up to a 50% reduction in the required amounts of biocides while maintaining the same level of protection.

Encapsulation works today — and minimises environmental impact

1

Efficient

Using encapsulation technology, equivalent antifouling performance can be obtained with as little as half the amount of biocides by encapsulation.

2

Cost Effective

Reducing the biocide, and in particular the copper, results in up to 20% cost savings today. It could be even more in the future as copper demand is growing.

3

Environmental Impact

The reduction in biocides can reduce the environmental impact with up to 50%.

Same or better performance

Hundreds of tests show equivalent or better performance compared to traditional more toxic coatings. The encapsulation technology has been proven both statically through panel tests and dynamically in the yacht market.

Copper is the major cost

Approximately 80% of antifouling coatings are copper-based, a major cost factor susceptible to economic conditions. Post-corona supply constraints have caused copper price spikes. A weight breakdown of large vessel paint reveals up to 40% as cuprous oxide.
To tackle copper-related cost fluctuations, it’s crucial to explore alternative approaches for reduced copper usage while maintaining coating effectiveness. Innovative solutions can help mitigate price impacts, providing more economically stable coating options for the industry.

Growing demand: Implications for copper and coatings

Copper constitutes up to 40% of the total weight in typical wet marine coatings. The demand for copper is projected to witness substantial growth in the upcoming decades, driven in part by the shift towards electrification.
As copper demand rises, industries reliant on copper will seek to reduce dependency, mitigating potential future pricing risks.
