Project Summery

Seaweed cultivation could soon be scaled up however, thanks to a Belgian company which has experimented with textile sheets that can be seeded and stretched across frames and used for seaweed cultivation. Similar to rope-based cultivation, the seaweed attaches to the sheets and grows quickly. Unlike rope-based cultivation, however, a much greater density of seaweed can be produced – up to 16 kilogrammes of wet seaweed per square metre, which is as much as five times the yield from more traditional methods.

Seaweeds are potentially excellent sources of highly bioactive secondary metabolites that could represent useful leads in the development of new functional ingredients. They are a large and diverse group of simple, typically autotrophic organisms ranging from unicellular to multicellular forms.
Macroalgae (seaweeds) can be classified into three broad groups as red algae, brown algae and green algae, based on their pigmentation. In addition, many reports have been published regarding isolated compounds from seaweeds with various biological activities, demonstrating their ability to produce important metabolites unlike those found in terrestrial species. The main objective of this study is to evaluate the application of different concentrations of seaweed extract in enhancing the growth, yield, quality and nutrient uptake of plants grown in fields, under rain fed conditions.

Project Challenges

As plants, algae and some sessile invertebrates may grow in nearly monospecific assemblies, their collective biomass increases and if they compete hard enough some die, freeing up space. The concurrent increase in biomass and decrease in density is called self-thinning, and its trajectory over time or maximum values represent a boundary condition. For a single stand developing over time the boundary defines the carrying capacity of the environment but the most extreme trajectories emulate the efficiency of species in packing biomass into space.

Project Mission

Spread across a wide area, the technology offers the prospect of large-scale seaweed farming. Demand for seaweed is potentially huge. Company says that seaweed will be a “future source for food, food additives and feed, as well as for chemicals, biochemicals and biofuels.” Seaweed production also offers comparative environmental benefits. Seaweed can absorb nutrients, for example from fish farms, while also absorbing carbon dioxide as it grows. Seaweed farms using the textile technology can also become havens for ocean life.

Following the completion of the project in July 2015, the project promoters aim to establish a spin-off company that will produce seaweed using the seeded sheets across a 2 to 3 hectare area. The project received financial support from the EU Seventh Framework Programme for Research and Technological Development.
