  • Labelled Solution
Label Date January 23, 2025
From Monaco
Maturity stage TRL 9 / CRI 2 - Commercial Trial Small Scale

The solution addresses the environmental challenges posed by massive sargassum accumulation in UNESCO biosphere reserves and private properties. Through coastal collection efforts in bays by boats, the solution preserves and restore mangroves, coral reefs, and seagrasses to their natural habitats. Central to this restoration is a patent-pending biological formula, which effectively absorbs toxic heavy metals and microplastics. To ensure eco-friendly collection on the beaches, electric vehicles are utilized and scalable carts, safeguarding sea turtle and bird nesting sites, and mitigating coastal erosion and noise pollution. Finally, employing scientific techniques, sargassum and local green waste are transformed into nutrient-rich compost, free of any trace of arsenic, revitalizing soil health, enhancing local crop yields, and minimizing landfill waste and greenhouse gas emissions.

The Environmental Benefits

  • Once accredited under the Gold Standard, each ton of sargassum removed can generate valuable carbon credits
  • Once sargassum is collected, families, including women and children, can enjoy beautiful, clean beaches for recreational activities
  • By the high-quality compost, small farmers can grow fresh local fruits and vegetables, increasing farm-to-table options in restaurants and direct stalls in local markets
  • Greenhouse gas emissions are reduced by keeping sargassum and green waste out of landfills, turning them into valuable compost and biochar: each project helps eliminate 20,000 tons of CO2e—making a real difference for our planet
  • By supplying local farmers with biochar and compost, we help cut greenhouse gas emissions by reducing methane emissions, while also boosting soil fertility and decreasing the need for chemical fertilizers.
  • The solution significantly boosts marine biodiversity by effectively removing harmful sargassum blooms, which can suffocate coral reefs and inhibit seagrass growth
  • Efforts to control sargassum blooms directly support small-scale fishermen by removing the sargassum that blocks their access to fishing grounds

The Financial Benefits

  • The solution cuts operational costs by 40–50% compared to traditional methods, thanks to efficient equipment and eliminating costly landfill transportation fees: this cost-effective approach makes it a more sustainable and economically viable alternative
  • Clients face minimal financial risk with our solution, as we pre-sell carbon credits to cover equipment and setup costs: this allows them to adopt our sustainable approach without upfront investment, securing immediate economic benefits compared to costly
  • The solution offers lower total cost of ownership compared to mainstream methods: by reducing landfill fees, fuel consumption, and labor costs, clients can save up to 50% on operational expenses, making it a more cost-effective long-term solution
  • The payback time for our solution is significantly shorter than traditional methods: with revenue from carbon credits and reduced operational costs, clients often achieve ROI by year 2, while mainstream alternatives do not generate any ROI at all
