BioFlux™ Technology: Low-Carbon SAF and Renewable Diesel from Biobased Feedstocks
Sulzer BioFlux process transforms biobased fats, oils and greases - including used cooking oil (UCO), animal tallow, and distillers corn oil (DCO) - into premium sustainable aviation fuel (SAF) and renewable diesel.
Whether you're a refinery planning your renewable fuels transition, an ethanol producer seeking diversification, or an investor evaluating sustainable fuel opportunities, BioFlux delivers the industry's fastest payback and lowest total cost of production with its cutting edge efficient liquid full reactor design and advanced internal mixing.
Sulzer licenses the BioFlux technology under an exclusive cooperation with Duke Technologies LLC.

BioFlux can process a wide range of lipid-based feedstocks, including used cooking oil (UCO), animal fats, tallow, and distillers corn oil (DCO). Its flexible design allows seamless integration of multiple feed types to meet sustainability goals and feedstock availability.
Thanks to its modular design, BioFlux can be deployed and operational in as little as 24 months, reducing engineering complexity and minimizing disruption to existing facilities.
BioFlux delivers low total cost of production, rapid ROI (<3 years), 25% CAPEX reduction, and 15–20% OPEX reduction compared to conventional solutions. It’s designed for both operational efficiency and long-term profitability.
Yes. BioFlux is suitable for both new (grassroots) installations and revamp projects. Its integration flexibility enables deployment within existing sites with minimal modification.
BioFlux produces Renewable Diesel (RD), Sustainable Aviation Fuel (SAF), and optionally bio-naphtha or bio-propane, depending on the configuration. These fuels meet or exceed industry standards such as ASTM D975 and EN590.
By processing low-carbon feedstocks like UCO, Tallow, DCO and with integrated hydrogen production, BioFlux helps achieve lower lifecycle carbon intensity, supports compliance with global SAF regulations, and reduces dependency on fossil-based hydrogen.
As opposed to a conventional trickle bed hydrotreatment reactor design, BioFlux uses a novel innovative liquid full reactor design with proprietary internals design which allows to operate the reactor in a single continuous liquid phase, maximizing the volumetric flux through the reactor. This helps in improved hydrogen availability in the reactor, better thermal heat management, lower tendency for cracking/fouling and overall lower capital and operating costs of the production.
