Preventing fouling at the source

Biofouling is one of the biggest challenges for aquaculture and marine infrastructure. Any surface in contact with water quickly becomes colonized — first by bacteria and biofilm, then algae, and eventually larger organisms such as mussels, barnacles, and tunicates. This process reduces oxygen flow, lowers yields in aquaculture, and causes heavy cleaning and maintenance costs.

Traditional antifouling methods rely on toxic coatings that leach metals or biocides. These harm the environment and are increasingly restricted by regulation.

Parx Materials offers a sustainable alternative.
Our Passive Action Polymer Technology™ integrate the technology into the surface of plastics, changing the surface properties in a way that prevents adhesion at the very beginning of the fouling cascade. By blocking bacteria and biofilm formation, we disrupt the entire settlement process.

• Higher Yield: Shellfish grow larger and healthier in cleaner systems.

• Lower Costs: Less fouling means less cleaning and longer equipment life.

• Sustainable: No leaching, no toxins — safe for both environment and food-contact applications.

• Future Proof: Ready for a world moving away from toxic antifouling coatings.

We already have several projects running in aquaculture and fishing applications, where Parx-treated nets and crates remain dramatically cleaner after long-term immersion, while also delivering larger and healthier shellfish.
