Production of high-value biostimulants in containers
Sirputis modular format equipment “Biostim 500 Compact” transforms fresh seaweed into stabilized, high-value biostimulant ingredients that support sustainable agriculture and the blue bioeconomy.
What We Deliver
Modular equipment and containerized processing units covering the full chain:
from raw seaweed → to liquid biostimulant extracts.
Works with wet or semi-dry biomass, including Sargassum, Alaria, Kappaphycus, Saccharina, Giant Kelp, and more.
Core Capabilities
-
Wet biomass intake and preparation
-
Mechanical cell disruption releasing alginate polysaccharides, fucoidan, laminarin, polyphenols
-
Stabilized liquid biostimulant output
-
Optional pulp pressing for additional product streams
Process Overview
- Seaweed disintegration into a controlled water-based slurry
- Bioactive release via mechanical cell disruption
- Separation of the liquid extract — the biostimulant product
- Pressing and optional drying of remaining pulp
Containerized extraction unit designed for
500kg/h wet weight input

Illustrative mass balance per 1,000 kg of wet seaweed (10% dry matter assumed):
Input = 1000 kg (100 kg DM + 900 kg water)
Output = 300 kg cake (78 kg DM + 222 kg water) + 700 kg liquid (22 kg DM + 678 kg water) = 1000 kg total
DM in = 100 kg; DM out = 78 + 22 = 100 kg
Actual splits depend on species, dry matter and press settings and are confirmed in trials.
Suitable for pilot sites, coastal installations, and industrial facilities.
