Sargasso is floating algae floating on thousands of kilometres that end up aground mainly on the sides of the Caribbean area with the Mexico. These gigantic strandings create many disorders :

While environmental issues are now at the heart of the concerns, the collection of seaweed Sargasse before its stranding on beaches becoming a first-rate economic and ecological necessity.

Attempts to combat this phenomenon of pollution have been undertaken. Nonconforming or inappropriate dams have been installed, they broke apart quickly, debris runaway is stranded on the sides and contributed to an additional pollution.
Artisanal and little effective modes of collection have also been implemented and were paradoxically for a long time an obstacle to the release of this sector of clean-up to eventually give way to more efficient.

Currently, local actors, in the face of the seriousness of the situation and aware of their interest in protecting the ecological heritage of their regions are now ready to be open to other proposals.

AlgeaNova, specialist in the design of marine devices, is today able to offer a complete range of remediation to contain the sargasse at sea, harvest it and value it

Since 2010, the development of Sargasso was exponential due to agricultural pollution in the basin of the Amazon and a rise in temperature due to climate warming. The currents cause the drift of huge benches of this floating Brown algae which sometimes extend over several dozen hectares to the Islands Caribbean and the coast of the Gulf of the Mexico. These gigantic Sargasso strandings are a scourge economic and environmental.

The beaches are overrun and become impassable. The Sargasse is a real health problem, It is allergenic and makes so swimming impossible. After stranding, it ferments and gives off a stench.

The most frequently used solution is cleaning the beaches using bulldozers. Tons of contaminated sand mixed with decomposing algae are collected, This process causes an irreparable erosion of the beaches. The back and forth incessant public works machinery and noise pollution make ar beaches during much of the day.

This sand-seaweed mix collected is then crammed into spaces requisitioned for this purpose and continues to rot in the open air. For kilometres round residents are bothered by the smell, children suffer from respiratory problems due to the toxic fumes.

Companies offering this service of cleaning the beaches bring no solution. This counterproductive method and anti ecological only effect is to ravage the beaches and move the pollution by trying to hide.

Our group, the AlgeaNova company belongs specializes in floating dams. We have decades of experience in the areas of protection against hydrocarbons, the underwater protection of ports and marinas to preserve funds during the underwater work, the protection of the beaches from the jellyfish with our patented floating barriers, as well as many more specific projects for specific protections.

For more than 2 years our group has invested nearly one million euros in research and development in order to find an appropriate response to the problem of the Sargasso.

Many trials of inappropriate barriers, designed by companies not specialized in this area have been made without success.

The Caribbean area is especially exposed to the risk of hurricanes. During the cyclone season the ideal is to dismantle the installations and store safe, but all existing barriers are not removable. The human and technical resources to implement do not consider dismantling and the necessary storage surfaces are too large. At the end of the hurricane season most of these dams were in the water is destroyed and reclamation costs are very important.

As a first step, our group has refused to sell its gates because we felt them incomplete. We preferred to wait and undertake a series of studies to analyze all the barriers of the market to determine the negative points of inadequate systems to address the problem of the Sargasso. At the end of months of research, our engineers have the first conclusions and we started to realize prototypes.

After more than a year of research and more than a dozen prototype installed at sea to study the behavior of the barriers in the face of the elements and their ability to effectively retain algae we decided to install Punta Cana Punta Cana Group partnered with a barrier of 200 m.

To be closer to our customers in the Caribbean our group has created the company AlgeaNova. We are to the facts of the problems, and this proximity allows us to better listen to improve our services according to your needs.

At the end of the bad season we give the barrier in place with reduced resources and a small team of 5 to 6 employees during a week.
