Algas Organics proposes solutions for combating sargassum

On Wednesday, February 27th, Algas Organics, in collaboration with the Belize Tourism Industry Association (BTIA), held a presentation for stakeholders on their solution for turning sargassum into something positive. The company was founded in 2014 by CEO Johanan Dujon, who led the presentation to hoteliers and business owners from the island. His proposal centered on conduction individual surveys to the affected areas and bringing their equipment to collect the sargassum and take it away for processing and conversion into fertilizer and bio-pesticides.

Dujon’s second proposal to the stakeholders was the possibility of opening a processing plant in Belize, which many agreed would be a great idea not only for the removal of the sargassum but also for creating employment for Belizeans. Glenford Eiley, Vice Chairman of the Belize Tourism Board (BTB), reached out to Dujon after he found out about the work Algas has done around the Caribbean region. He told The San Pedro Sun that he sees a tremendous opportunity and a viable solution to the sargassum with the proposals Algas presented.

NASA spots millions of tons of sargassum in Caribbean

Last month, NASA’s satellites captured images which showed almost clear seas in the Western Caribbean and the Gulf of Mexico. However, photographs paint a completely different picture for the Eastern Caribbean, where a moderate amount of sargassum was recorded. Researchers believe the isolated batches could foreshadow what the Caribbean region should expect for the rest of 2020.

The bulletin continues, “In all [Caribbean] regions combined, the total sargassum amount increased from 1.6 million tons in February to [approximately] 4.3 million metric tons in March, similar to March 2015 (4.2 million tons) and March 2019 (4.7 million tons).”

The crucial difference between 2019’s seaweed development and this year’s, is the location.

In 2019, the majority of sargassum in the area developed in the central and western Caribbean. However, this year the satellite images show the development in and around the lower Lesser Antilles.

“Looking ahead, the eastern Caribbean will see large amounts of sargassum in April to June 2020,” stated the bulletin.

USF states that Cayman and the wider western Caribbean can expect small to moderate amounts of sargassum leading into summer.

Sargassum slowly washing up on Belizean shores

The sargassum seaweed is slowly making its presence known on the windward shores of Ambergris Caye. According to satellite images, large mats have been spotted far out on the Atlantic Ocean, entering the warm waters of the Caribbean Sea, to then inundate the region with tons of the brown algae. Island authorities are aware of the looming threat and are considering the necessary precautions to deal with the matter if its presence escalates. Mayor Daniel Guerrero stated that a busy sargassum season can be expected this year. He indicated that his administration has a lot on its plate as they wade through the COVID-19 pandemic, but they are monitoring the sargassum edging its way to our shores. The algae has been noticed on the beaches in and around downtown, where it is slowly beginning to accumulate.

Compared to the same time last year, the arrival of sargassum seems delayed. By May 2019, mounds of decaying sargassum were causing a dent in the tourism economy across the region. Due to COVID-19, 2020’s tourism season might be considered over, but the sargassum will still affect the health of people and wildlife on the island. In March of this year, satellite images showed a large amount of sargassum floating on the Eastern Caribbean. According to researchers from the University of South Florida USA, that amount is more than two million tons of sargassum, which continues to increase significantly as it makes its way to the Western Caribbean.

Caribbean Sargassum Virtual Workshop To Benefit Belize

Sargassum Products for Climate Resilience to mitigate harsh impacts on Caribbean States - The Caribbean Regional Fisheries Mechanism (CRFM) and Plant & Food Research, a New Zealand Crown Research Institute, will host a virtual training workshop on Wednesday, 3 March 2021. The session—which will be conducted with the assistance of Prof Mona Webber of the Marine Science Centre, UWI, Mona Campus, Jamaica—will focus on techniques for harvesting, handling, species identification and processing of Sargassum seaweed for initial evaluation.

It will be attended by the four target countries for field work, The Bahamas, Barbados, Belize, and Jamaica, as well as other interested CARICOM States and organizations such as CARDI, CERMES UWI, University of Belize, the Caribbean Network of Fisherfolk Organization (CNFO) and IAEA.

The training supports the effective implementation of the New Zealand Ministry of Foreign Affairs and Trade-funded project entitled, Developing Sargassum Products for Climate Resilience in the Caribbean, due to commence in April 2021. In addition to the target countries, other CRFM Member States will benefit either directly or indirectly from the project, which aims to mitigate the environmental and economic impacts of Sargassum seaweed influxes in affected Caribbean countries through the creation of inclusive value chains.

Since 2011, periodic influxes of massive quantities of Sargassum seaweed have been entering Caribbean waters, resulting in substantial economic losses and adverse impacts on human and environmental health.

The Outlook of 2021 Sargassum blooms in the Caribbean Sea and Gulf of Mexico, released by the University of South Florida Optical Oceanography Lab on at the end of February 2021 indicated that, “…the eastern [Caribbean Sea] will likely experience increased amounts of Sargassum in March and April 2021, while some of the Lesser Antilles Islands will continue experiencing beaching events on both their windward leeward beaches." It forecasted that the situation could continue into summer, with the overall bloom intensity possibly like that of 2019.

In September 2020, the CRFM entered into a 3-year collaborative agreement with Plant & Food Research, to address Sargassum seaweed influxes in affected Caribbean countries. Plant & Food Research and the CRFM are collaborating to explore the creation of new technologies and value chains from the Sargassum seaweed. The project aims to develop Sargassum-derived product prototypes and production processes, including a commercialization strategy to support its marketing.

The 2021 Sargasso outlook from NASA is HIGH.

Outlook of 2021 Sargassum blooms in the Caribbean Sea and Gulf of Mexico

Feb 28th, 2021, by University of South Florida Optical Oceanography Lab ([email protected])

The maps below show Sargassum abundance, with warm colors representing high abundance. In February 2021, the Sargassum amount remained high across the central Atlantic. Large amount of Sargassum was observed in the Central West Atlantic (CWA, i.e., the region east of the Lesser Antilles in the maps below) while the amount in Central East Atlantic (CEA) decreased. Moderate amount appeared in the eastern Caribbean Sea (CS), while the following regions are still largely free of Sargassum mats: western CS, Gulf of Mexico (GOM), and Florida Straits. In all regions combined, total amount decreased from ~5.1M tons in Jan. 2021 to ~4.6M tons in Feb. 2021, similar to February 2019 (4.3M) but much larger than all previous February months except Feb. 2018 (10.3M).

Looking ahead, the eastern CS will likely experience increased amounts of Sargassum in Mar and Apr 2021, while some of the Lesser Antilles Islands will continue experiencing beaching events on both their windward leeward beaches. This situation may continue into the summer when Sargassum may be transported to the GoM. Overall, this year appears to be similar to 2019. We will keep a close eye on how Sargassum in the CS and the tropical Atlantic may evolve in the next two months. More updates will be provided by the end of February 2021, and more information and near real-time imagery can be found under the Sargassum Watch System (SaWS, https://optics.marine.usf.edu/projects/saws.html).

IIt can be used to build roads with light traffic, sidewalks, among others. Photo: (Rosario Ruiz, Placeholder)

‘Sargacreto’, the new construction material made of sargassum

Cancun, Quintana Roo, (March 18, 2021).- “Although there is not much research regarding its use, sargassum is a new raw material that nature has provided us, and that can be used at an industrial level”, said Dagoberto Ruiz Lavín, director of Grupo Dakatso, when unveiling a new way of taking advantage the alga: the innovative Sargacreto.

He said that for years they have been working on finding ways to industrialize the algae, which for most is seen as a waste. For Sargacreto, the sargassum is harvested in the high seas: “the one that works for us is the living one, it is washed, the salinity is removed with biodegradable chemicals, we crushed it and then we dehydrate it using UV rays”.

This dehydrated sargassum is mixed with concrete in a concentration of 35 to 40 percent. The patent for this procedure is pending and the resulting material can be used to build roads with light traffic (such as hydraulic concrete or paving stones), sidewalks, blocks, joists, vaults, patterned floors, and perimeter fences. The material can also be used for public parks (benches, playgrounds, and green areas).

“This does not generate leachate into the environment, as opposed to the case when the algae is sent to a landfill, where it becomes a source of contamination of the water table, and causing damage to the environment,” he continued.

The project will evolve and they hope to continue producing on a large scale.

The Sargacreto project will go through an environmental audit process to obtain the certificate of responsible production, so the company will validate the entire production process, review what type of raw material and ingredients were used, that the machinery and infrastructure are 100% ecological, and how much waste it generates or if it produces greenhouse gases.

The Sargacreto will also serve to create artificial reefs: “we have documented that these pieces when placed in saltwater are able to regenerate the reef, the algae they contain allow marine life to grow.” Ruiz Lavín said that they are working together with a German company to install an industrialization plant in Playa del Carmen, with which they will process sargassum and when the seaweed is not in season, they will recycle PET.

Regarding possible participation in the Maya Train project, the interviewee recalled that for two years as part of the Puerto Morelos Protocol it had been planned to make sleepers and stations with Sargacreto, for which he hopes that his proposal to use this material in the federal megaproject.

“All the sargassum that has arrived can be implemented in some phase of the project: stations, waiting areas, benches, and I think it would be very positive because apart from that we would generate employment for the locals,” he said.

He explained that the crusher they use, manufactured in China, reduces the volume of treated biomass to 10 percent, which can also serve as fertilizer for green areas in hotels.

For those of you that haven’t stumbled upon the satellite work the University of South Florida does in connection with NOAA on Sagassum monitoring and prediction, here is the link to their site. At the end of March they predicted that 2021 would be the 2nd worst year yet, or maybe the worst.

Miguel Alamilla: According to the USF Optical Oceanography Lab, the Abundance of sargassum recorded in May in the Caribbean Sea and West Central Atlantic has set a new historical record. It is expected that the amount of sargassum in the Caribbean Sea will continue to increase during summer leading to more beaching events.

========

Outlook of 2021 Sargassum blooms in the Caribbean Sea and Gulf of Mexico* May 31st, 2021, by University of South Florida Optical Oceanography Lab

The maps below show Sargassum abundance, with warm colors representing high abundance. In May 2021, the Sargassum amount continued to increase across the central west Atlantic (CWA) and the Caribbean Sea (CS), which also sets a new historical record for the month of May. Large amount of Sargassum was observed in CWA, i.e., the region east of the Lesser Antilles in the maps below, and in the entire CS. Moderate amount has been transported from the CS to the Gulf of Mexico (GoM), the Straits of Florida, and along the east coast of Florida following the Loop Current, Florida Current, and the Gulf Stream, respectively. Correspondingly, small amount of Sargassum was observed in the Straits of Florida and along the east coast of Florida with possible beaching events. On the other hand, significant beaching events may have occurred around most of the Caribbean nations and islands.

Looking ahead, 2021 will be another major Sargassum year, and the Sargassum amount in the CS will likely increase continuously into the summer, accompanied with more beaching events. Meanwhile, Sargassum transport to the GoM will also continue, indicating more beaching events in the Florida Keys and along the east coast of Florida. We will keep a close eye on how Sargassum in the CS and GoM as well as in the tropical Atlantic may evolve in the next two months. More updates will be provided by the end of June 2021, and more information and near real-time imagery can be found under the Sargassum Watch System (SaWS, https://optics.marine.usf.edu/projects/saws.html).
