A new net weaving for seaweed cultivation
Adrian Martinez, head of Technored, a former partner of the AtSea consortium, a net weaving specialist in Spain, joins the team. By modifying some of his machines, he developed a net weave specially adapted to the cultivation of different types of algae.
The aim is to produce only "Terroir" seaweed in the most suitable areas of the country concerned. The seaweed could thus be "vintage"; monitoring buoys would be installed to collect a range of data for the customer: salinity, turbidity, sunshine, nutrients, etc., whereas currently the processed seaweed comes from all over the world (often from highly polluted seas in Asia) and is mixed.
In terms of food production, large distribution groups are unable to obtain very large quantities of seaweed from the same region and therefore cannot benefit from a stable raw material throughout the year. The originality and know-how of AtSeaNova is to offer huge fields for a vintage Terroir culture.
Construction of the head office in Tangier.
At the same time, the group expands in Tangier. An 11,000m2 building is built to meet the future needs of ProjiNova, FiletNova, and AtSeaNova.
Signing of the contract AtSeaNova-Aramco
In 2021 AtSeaNova signed a first contract for one hectare with the oil giant Aramco, a sample of a larger project that embodies all the conceptual and technological innovation developed above. After months of studies to define the ideal location and the most suitable types of algae, it has been decided that this hectare will be installed in early 2023 in Yanbu, Saudi Arabia. The first barge built by NavyNova will be used for industrial seeding and harvesting of seaweed.
The structures have been designed to cultivate all the existing algae on the planet. The group's biologists reproduce locally existing algae without ever moving them. The structure remains the same regardless of the algae to be cultivated. The only difference is the quality of the specific net to each type of algae.
These algae are intended to be used for human and animal food, cosmetics, pharmaceuticals, energy, compost for agriculture etc...
This project is a world first.
The Holding's global project is based on the vision of its CEO, René Munier, convinced that our planet will have to use the great diversity of algae and their many nutritional qualities in the near future to meet its needs.
Installation of new fields.
In 2023, the Holding plans to install fields of several hundred hectares
- New barge manufacturing technique by NavyNova.
- New marine erosion barrier.
Construction with a new material HDPE.
Following the "Covid and war" crises, commodity prices are skyrocketing.
The group decided to abandon the construction of aluminium barges (a material becoming too expensive and requiring too much maintenance) in favour of HDPE barges. This innovation makes it possible, among other things, to eliminate the use of antifouling (excessively polluting) for the maintenance of aluminium hulls.
Recent investments have enabled the Holding to equip itself with state-of-the-art machines capable of water jet cutting and welding HDPE sheets together.
The first boat (NAB101) was launched in Mexico in October 2022 and the second (NAB102) was delivered in late December 2022.
Three units made up the first aluminium Sargasso harvesting barges, the harvesting mother barge 'NH101 & 301' and 2 cargo ships 'NC101,301 & 102, 302' for transport. This fleet required 6 x 150hp engines, plus tractor, trailer and crane. The whole process with the employment of 12 people was very expensive in terms of investment and operation.
The group took the decision to replace the 3 units of the old system with :
A single amphibious barge 'NHR101' made of the new raw material, (HDPE) equipped with a crane and a compactor truck also equipped with a crane.
For the same service, a single boat with two 150hp engines and 4 employees are sufficient. These latest innovations allow a fast, solid, flexible assembly, requiring minimal maintenance and easily recyclable.
This latest concept is completely autonomous as the barge harvests the seaweed, transports it ashore and unloads it autonomously with its crane. Then, the compactor truck with its crane collects the bags and transports them to the processing site.
NHR101 the new 11x5.5m HDPE amphibious barge is being built for a Mexican customer. It was designed by the group's engineers and developed using a UNIQUE construction method which allows the barges to be delivered in 7 parts with their equipment grouped in 4 containers.
Each barge is assembled on site and launched in a maximum of 3 weeks compared to more than 12 months using the old method.
Revolutionary new net
La Holding a signé un accord d’exclusivité mondiale de commercialisation, construction et installation de ces barrières.
Cette nouvelle activité relative à la protection des côtes maritimes et, des routes et autres sites dans les déserts bénéficiera d’un développement rapide du fait de l’implantation du groupe dans 6 pays et 3 continents.
A French inventor, Dominique Michon, developed and patented a net barrier in collaboration with the French government agency CEREMA. It protects coasts from erosion and retains sand on eroded beaches.
It also makes it possible to control the progress of dunes in deserts.
Dominique Michon recently contacted the group to manufacture these barriers for his contracts in France.
The Holding has signed an exclusive worldwide agreement to market, build and install these barriers.
This new activity relating to the protection of maritime coasts and roads and other sites in deserts will benefit from quick development due to the group's establishment in 6 countries and 3 continents.
The Holding is fully aware to have a role to play in order to contribute as much as possible to the protection of our planet.
With its 175 engineers, technicians and workers spread over several continents, HoldiNova studies all types of projects, on land, at sea and in the deserts.
The only condition is to imagine, create and develop in an eco-responsible manner!
