The uses and applications of seaweeds are many and varied.
Phycocolloids (alginate, agar and carrageenan) are used in thousands of food and personal care products to thicken, gel and emulsify.
Different seaweed species have of course been eaten throughout history by humans. Seaweeds are also added to livestock feed and aquafeed in increasing numbers, in some cases for health benefits or added protein, in other cases with the express intention of reducing the methane exhaust of livestock.
The health properties of different seaweed species continue to excite researchers, and pharmaceutical, nutraceutical and cosmetic applications are numerous.
To nourish plants and soils, seaweeds are also widely used to make biostimulants, and a new field of experimentation is the creation of biochar from seaweed.
Creating bioplastics, textiles, building materials, paper, inks, paints and dyes out of seaweeds is a new area that is attracting a lot of research.
Some people have plans to use seaweeds explicitly for long-term carbon sequestration. Other minor fields at the moment are energy, waste and wastewater treatment
A wider exploration of the pluses and minuses, challenges and opportunities of the myriad ways seaweeds can be used is in order. For now, we are just splitting up the companies in our database according to the application fields mentioned above.
You can filter or sort by country or subsector: agar, carrageenan, alginate.
