Renewable Raw Materials — Overview — Zenbiochem
Our approach

From biomass to molecules

We combine enzyme engineering, precision fermentation, and green chemistry to convert underutilised natural polymers into high-value functional chemicals — spanning pharmaceuticals, personal care, bioplastics, and antimicrobials.

Innovation platforms — click to explore
Aquaculture

Seaweed-based functional materials

Marine polysaccharides transformed into bioplastic precursors, cosmetic actives, and broad-spectrum antimicrobials.

Agriculture + Aquaculture

Functional carbohydrates for gut health & personal care

Enzyme-driven modification of dietary carbohydrates to produce prebiotics, postbiotics, and skin-care actives with proven bioactivity.

How it works — field to molecule
Stage 01

Feedstock sourcing

Renewable biomass from certified agricultural and aquaculture supply chains with full traceability.

SeaweedCrop residuesPlant sugars
Stage 02

Pre-treatment & fractionation

Mild physical and chemical pre-treatment separates target polymer fractions for downstream conversion.

Steam explosionAqueous extraction
Stage 03

Enzyme & fermentation

Proprietary enzyme cocktails and engineered microbial hosts convert polymers with high selectivity.

BiocatalysisFermentation
Stage 04

Purification & supply

Downstream processing delivers pharma- or industrial-grade products meeting customer specifications.

Why Zenbiochem

100% renewable feedstocks

No petroleum-derived precursors. Every starting material traces back to agriculture or aquaculture.

Proprietary enzyme systems

In-house enzyme libraries deliver performance and IP advantages that protect partners’ supply security.

Multi-sector impact

Platforms serve pharma, personal care, food & nutrition, and materials — broad commercial resilience.
