Parx Materials Technology Preventing Biofouling in Marine

Harvesting More and Better Shellfish

In a recent field trial by an experienced and long-time marine aquaculture farm, culture tanks were brought ashore to harvest Abalone, set out to grow six months ago. They set out some hundreds of tanks for growing these shell fish. This delicacy is growing to its full size in plastic culture equipment, set out in the waters for a period of 6 months. Usually during this time, the plastic culture tanks get covered with unwanted aquatic species obstructing the flow of fresh water through the tanks, a common problem in marine aquaculture. But not this time. This time a portion of the tanks (about 100 pieces) were produced using Saniconcentrate of Parx Materials N.V. These tanks are still clean after 6 months in the ocean, without fouling. They developed significantly better Abalones, growing larger than in the normal tanks. This means more yield of this valuable product and more profit for the aquaculture farm.

Sustainably improving the material

Saniconcentrate is a modified polymer concentrate that is added to plastics prior to the manufacturing process of the tanks. The concentrate carries the trace element of Zinc, a nutrient with ‘utmost biological importance’, into the material. The incorporation of this trace element is achieved by a novel and patented method developed by an interdisciplinary team of scientists specialized in biomimicry, biochemistry, material science and polymerization processes. An idea inspired by the defense mechanism in the human skin, where the trace element of Zinc is vital for a healthy immune system protecting us against bacteria and viruses.

By incorporating this trace element, the materials mechanical/physical properties are improved, making the material surface resistant to the adhesion of fouling, bacteria and biofilm. An antifouling solution that does not leach out and does not contaminate the oceans. Nothing of the technology is ‘consumed’ over the lifespan of the product, so the technology remains at full strength and does not fade away.

The technology is unique as there are no biocides or other toxic components involved. It only cleverly incorporates the biocompatible trace element like it is found in green vegetables such as broccoli and spinach or how it is present in your multi-vitamins.

    Biodegradable Plastic under Maritime Conditions

    Contributing to Keeping Plastic Garbage out of Our Seas

    Researchers develop bio-based plastics that directly biodegrade in the sea. These materials would be utilized as an alternative to products whose entry into the sea cannot always be avoided, e.g. products utilized by fisheries in their everyday activities.   more
