Honey-colored Cocura Oil™ separating in a laboratory vessel

Cocura Oil platform

The simplest route from sugar to refinery-ready oil.

Cocura Oil™ is an extracellular oil platform built to bypass the recovery, sterility, and scale-up bottlenecks that have held back fermentation-derived oils.

The industry problem

The refinery is mature. The biological bridge to it is not.

Hydrotreating is already a proven route to aviation fuel, but the supply of affordable, sustainable lipid feedstocks is constrained. Expensive processing steps keep many fermentation pathways from competing with existing lipid sources.

The industry does not need another molecule that can be made. It needs an oil that can be made, recovered and scaled economically.

The Cocura Oil™ answer

Radical simplicity: make the oil outside the cell.

Cocura Oil™ is secreted directly into the broth by Safion’s proprietary engineered host, placing the product where it can be recovered simply and economically: outside the cell and in a separate dense oil phase.

01

Extracellular by design

The product does not need to be liberated from biomass. That removes the most punishing unit operations from conventional microbial-oil recovery.

02

Self-preserving chemistry

The organism acidifies its own broth, suppressing common contaminants and reducing sterility burden.

03

Native pathway stability

Safion improves an endogenous pathway rather than asking the host to carry a heavily foreign metabolic program.

04

Platform chemistry

The same short-chain, hydroxylated lipid supports fuel, lubricant, flavor, surfactant and antimicrobial value chains.

Evidence, not aspiration

Demonstrated from bench scale to 10,000 L.

Safion has repeatedly scaled the fermentation and primary recovery process, producing metric-ton quantities and validating the same simple separation logic at manufacturing-relevant scale.

One oil. Multiple markets.

Commodity volume. Specialty value.

A broad SAF outlet can absorb the majority of production, while smaller-volume, higher-value products strengthen plant economics and reduce reliance on a single market.

Core volume outlet

Sustainable aviation fuel

Hydrotreatable lipid feedstock designed to enter existing HEFA and refinery infrastructure.

Performance market

High-performance lubricants

Hydroxylated short-chain lipids and derivatives for friction modification and specialty lubrication.

High-value co-product

Massoia lactone

A low-CI natural flavor and fragrance ingredient positioned as an alternative to bark-derived massoia supply chains.

Formulation market

Surfactants

Amphiphilic lipid chemistry for wetting, cleaning, emulsification and specialty formulations.

Functional ingredient

Antimicrobial agents

Intact Cocura Oil chemistry with demonstrated bactericidal potential for selected applications.

The platform is designed so that SAF scale does not depend on SAF margin alone.

Product allocation can follow market demand: preserve a large-volume outlet for hydrotreating while selectively capturing higher-value specialty markets.

Additional products in development include low CI urethanes, 3D printable polymers, composites, and coatings.

Capital-light commercialization

Deploy the biology. Reuse the steel.

Safion's commercial model is built around leasing existing idled fermentation capacity, adding a compact Cocura Oil recovery train, and using mature regional hydrotreating infrastructure instead of financing a greenfield complex.

From idle capacity to multiple revenue streams.

The operating model is designed to push capital toward market proof and site profitability rather than toward new concrete, utilities and stainless steel that already exist.

Illustrative deployment footprint

Brownfield opportunities are already distributed across the map.

Representative geographies from Safion development materials illustrate the broader thesis: existing fermentation assets can be reactivated, upgraded with Cocura Oil technology and connected to real market pathways without building a new greenfield complex.

Reuse

Idled fermentation assets

Existing vessels, utilities, controls, labor pools and site infrastructure are reactivated rather than rebuilt.

Retrofit

Cocura Oil technology

Proprietary strain, fermentation recipe, controls and compact gravity recovery.

Connect

Existing refining network

Regional HEFA, hydrotreating, tolling and product distribution infrastructure.

Full-scale partner opportunity

The technology is ready for its next operating platform.

Safion is engaging facility owners, refiners, strategic offtakers and investors to move Cocura Oil™ into its next operating platform.
