Key Players
Competitive Landscape
Competition in keratin hydrolysate inputs splits between animal-protein hydrolysate manufacturers and peptide biostimulant producers. Marine crop-input specialists and crop-nutrition groups compete for the same formulation budget. Direct keratin evidence is concentrated among hydrolysate manufacturers. Adjacent platforms compete on crop proof and qualification support.
The competitive field shifted toward fertilizer integration in December 2025. Olmix and Violleau launched VIO ActiBoost following two years of market testing. Tessenderlo Kerley closed the Cinis Fertilizer asset transfer in June 2026. Those actions favor companies that can place biological or specialty inputs inside fertilizer manufacturing and distribution.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| June 2026: Algaia began LOCALITY agronomic field trials in Poland using seaweed-processing by-products under water-stress conditions. | Formulators need crop-response evidence for lower-input ingredients under field stress. | Marine by-products are being evaluated as agricultural ingredients instead of remaining process residues. | Validated fractions can be supplied to fertilizer and biostimulant formulators that need field-support data. |
| August 2025: Acadian Plant Health added its fifth CE-marked biostimulant under the EU Fertilising Products Regulation. | EU distributors need claims backed by recognized safety and performance assessment. | Biostimulant companies are expanding CE-qualified portfolios for multi-country sales. | Qualification-ready biological inputs can enter several EU markets through one conformity route. |
| February 2025: Olmix and INRAE renewed their research framework through 2030. | Crop-input manufacturers need scientific evidence to defend biological performance claims. | Biostimulant research is moving into longer institute partnerships with field and mechanistic work. | Companies with mature trial networks can shorten evidence development for formulation partners. |
BioAtlantis competes in crop-stress biology. Hello Nature and Bioiberica bring peptide or protein-hydrolysate platforms. SICIT Group supplies animal-protein hydrolysates and Tessenderlo Group brings crop-nutrition manufacturing.

Who leads the keratin hydrolysate inputs market?
SICIT Group has the clearest current corporate evidence of converting tanning residues into protein hydrolysates for agriculture. Bioiberica also documents agricultural protein-hydrolysate capability but does not state the same keratin-specific scope.
Which suppliers have documented qualification or quality approvals?
SICIT Group documents ISO 9001 quality management and Bioagricert suitability for organic farming. Hello Nature reports CE marking for five biostimulant formulas and several agricultural certifications.
Which companies provide protein or peptide crop-input products?
SICIT Group documents animal-protein hydrolysates for agricultural biostimulants. Bioiberica and Hello Nature use enzymatic hydrolysis to produce amino-acid or peptide platforms for plant health.
Which suppliers serve Europe and international markets?
Bioiberica sells in 80 countries. Algaia reaches all continents through JRS or partner networks. SICIT Group also operates through subsidiaries in North America and Asia.

Research Methodology
The companies mapped here illustrate the market structure rather than an exhaustive ranking. Inclusion requires current verifiable evidence that a company supplies keratin-derived hydrolysates for crop use or a directly competing protein or peptide crop-input platform within the defined market scope. Evidence comes from regulatory approvals and third-party certifications. Company announcements and public filings support dated corporate actions. Capabilities are attributed to the stated hydrolysate, biostimulant or crop-nutrition platform rather than generalised across broader corporate portfolios. Market-share estimates remain proprietary FMI assessments for the forecast period.
