BOATOWNER PEVASA AND MANUFACTURER ZUNIBAL develop ZUNFLOAT platform
The environment is the first challenge that we are facing in the last few years, because we begin to know the effects that the modern society is making to the planet. The overuse of the fishing resources and the water contamination is a truth that forces the tuna sector to start sustainable and responsible fishing practices, trying to achieve the minimum environmental impact over the oceans.
The Tuna Ship Owner PEVASA and the satellite buoys manufacturer ZUNIBAL created the project ECO-FAD and undertook a depth research during 2015 of the traditional FAD used in the majority of the tuna vessels and other commercial FAD existing in the market.
The main objective of this study was to design and develop a more sustainable solution, with less environmental impact to the ocean: the ZUNFLOAT marine platform.
The analysis compared the environmental aspects and the potential impacts of all the FADs that are currently used by the purse seiners, it is an “End of life analysis”, that studied the following issues:
− The raw materials consumed in the production.
− The residues generated in the manufacture process.
− The environmental effects of the end of life, when the products cannot longer be used.
The most important phases are the MANUFACTURE, the TRANSPORT and the END OF LIFE, where we have analyzed the following elements:MANUFACTURE
− Materials (stainless steel, plastics, ropes, cloths…).
− Raw material production.
− Raw material origin and transport way.TRANSPORT
− Product destination and transport to go there.
− % of the product sent to each destination.
END OF LIFE
− Final destination of the residues.
We also have analyzed the environmental impact of the FADs, studying these effects of global warming, acidification, eutrophication, photochemical rusting, ozone layer destruction, human toxicity, abiotic resources termination.
These are the results of the environmental impact of each system: traditional FAD, FAD1, FAD2 and ZUNFLOAT.It can be concluded that the traditional FAD generates the most environmental impact; it even generates more garbage than all the rest systems together, FAD1, FAD2, and ZUNFLOAT.
The reason is the end of life, because the continuous mechanical movement of the waves can cause the traditional FAD to break apart.
In the best scenario the residues go to the dumping site, but in the worst they go to the ocean’s bottom or remain drift floating, finally arriving to the beaches as garbage.
The study concluded that the traditional FAD generates 73,64% more residues to the water, while the ZUNFLOAT platform is manufactured in one unique strong piece that is reusable. The estimated life is 5 years, while the usual life of a traditional FAD is 1 year.
The analysis made in the Atlantic Ocean confirmed the ZUNFLOAT has a big strength and it supports the heavy weight of the object and behind, so it can be reused several times.
Moreover the ZUNFLOAT can extend the cycle of life, because it’s 100% recyclable.
In comparison with the other commercial FAD’s, the ZUNFLOAT is the solution that generates less global warming, acidification, eutrophication, photochemical rusting and human toxicity.
In summary, the ZUNFLOAT platform is cleaner than the traditional FAD in environmental terms, so it helps to the tuna fishing to be more responsible and sustainable.
The study proved the tradition FAD is the less sustainable object and it creates the more environmental impact to the oceans.
Hence PEVASA, committed to the sustainability of the fishing resources, has decided to progressively eliminate the tradition FAD from its purse seiners in the Indian and Atlantic oceans and introduce the use of the ZUNFLOAT platform.
With this action PEVASA aims to make cleaner our marine environment, to reduce its environmental impact and to improve the quality of our seas, today and tomorrow.
PEVASA wishes to invite all the Tuna Vessel Owners worldwide to commit to a progressive substitution of the platforms used in tuna fisheries.
