One Waste Stream → Multiple Sustainable Fuels

The global energy transition is accelerating, and industries like shipping, aviation and heavy transport urgently need scalable alternatives to fossil fuels.

The real challenge is not engines.

The real challenge is how to produce enough sustainable fuel without rebuilding the entire energy infrastructure.

At SWESTEP, we approach this challenge through circular carbon utilization.

Our catalytic conversion technology transforms hydrocarbon-based waste into synthetic diesel (EN590 quality) — always the primary output of the process.

At the same time, the process generates CO₂ and H₂O as output streams.

Instead of treating these as by-products, they can become valuable resources. By integrating additional processes, the CO₂ and H₂O can be used to produce green methanol or SAF, potentially creating almost the same energy volume as the diesel itself.

In other words:
One waste stream → multiple sustainable fuels.

• Diesel
• Methanol
• SAF

And because these fuels are drop-in compatible, the transition from fossil to non-fossil fuels can happen without major changes to existing engines, transport systems or fuel infrastructure.

Scaling the energy transition will require solutions that are not only sustainable — but also practical and deployable today.

The transition from fossil to non-fossil fuels does not always require new systems — sometimes it requires better use of the carbon we already have.
