Sasol and Topsoe are winding down Zaffra, the joint venture they launched in 2023 to accelerate sustainable aviation fuel development. The companies say the move isn’t a retreat from their partnership or from SAF but a deliberate shift toward a leaner structure they believe better fits where the market is heading.
Zaffra joint venture to be wound down
Sasol and Topsoe announced they’re preparing for the “orderly operational wind-down” of Zaffra, the joint venture established in 2023 to combine their sustainable aviation fuel capabilities. The decision came out of a strategic review of the partnership’s organizational structure—one that both companies say pointed clearly toward a leaner model for the next phase of SAF development.
Both companies were explicit that the process will be handled carefully, describing the wind-down as “disciplined, orderly, and compliant.” That framing matters. Joint ventures in emerging energy markets can unravel messily when strategic priorities diverge, and the language signals a managed exit rather than an abrupt closure.
Stakeholder communication sits at the center of the transition plan. Sasol and Topsoe say they’ll engage directly with Zaffra’s customers, employees, value-chain partners, and other relevant stakeholders throughout the process—protecting existing relationships, reducing uncertainty, and supporting continuity rather than simply shutting down and moving on.
Why the companies chose to restructure
The strategic review concluded that a more focused, flexible structure would better serve the next phase of SAF market development. The sector is evolving quickly, and a dedicated joint venture — with all the overhead and fixed coordination that entails — no longer appears to be the right fit for either company.
The logic isn’t that Zaffra failed. The market moved. What made sense as an organizational vehicle in 2023 may not be the most effective structure as SAF projects shift from early pipeline-building toward actual licensing and deployment. That’s a meaningful distinction.
The single-point licensor framework, established back in 2019, was identified as the right vehicle going forward. It already existed, carried a track record, and offered the flexibility both companies say they now need. Rather than maintaining a separate entity, Sasol and Topsoe are consolidating their collaboration into that proven structure — an organizational adjustment, not a strategic retreat.
Collaboration continues under the SPL framework
The SPL framework isn’t starting from scratch. Six licenses have already been signed under it, giving Sasol and Topsoe an active foundation to build on as Zaffra winds down. That existing activity makes the transition feel less like a disruption and more like a rebalancing of how the work gets done.
Through the SPL, the two companies will keep offering integrated technology solutions—combining Sasol’s Fischer-Tropsch fuel technology with Topsoe’s clean fuel expertise in a single licensing package. The combined offering stays intact. Only the organizational wrapper around it is changing.
There’s also room for deeper collaboration where specific projects demand it. Both companies noted they may establish more targeted structures for selected initiatives requiring closer coordination, so the SPL framework serves as the baseline with the option to layer on additional arrangements project by project. Both CEOs reaffirmed the partnership publicly. Simon Baloyi, President and CEO of Sasol, acknowledged Zaffra’s role in building a market foundation and said the company remains “committed to building on this foundation through our long-standing technology-led collaboration with Topsoe.” Elena Scaltritti, President and CEO of Topsoe, echoed that sentiment, noting the importance of letting the collaboration model evolve alongside the market.
Background: A 30-year partnership and the origins of Zaffra
To understand why this restructuring is an adjustment rather than a break, it helps to know the history. Sasol and Topsoe have worked together for more than 30 years — a long track record of jointly commercializing complex, first-of-a-kind solutions. That kind of relationship doesn’t typically dissolve over a disagreement about org charts.
Zaffra was created in 2023 specifically to consolidate their combined SAF capabilities at a moment when the sector was gaining serious regulatory and commercial momentum. During its operation, the joint venture built market insight, developed a project pipeline, and engaged customers and partners across the value chain. That groundwork doesn’t disappear with the entity.
Sasol is a global chemicals and energy company headquartered in South Africa, listed on both the JSE and NYSE, and operating across 22 countries. Topsoe is a Danish energy transition technology provider founded in 1940, with more than 2,800 employees focused on transforming renewable resources into fuels and chemicals. Their technologies are complementary — which is precisely why the SPL framework, rather than a clean separation, is the logical next step.
A new, leaner structure
The core facts here are straightforward. Zaffra, launched in 2023, is being wound down after a strategic review determined a more flexible structure would better serve the evolving SAF market. Collaboration between Sasol and Topsoe continues through the single-point licensor framework, which already has six signed licenses and will serve as the primary vehicle for their technology-led cooperation going forward.
The wind-down will be managed carefully, with active engagement of customers, employees, and partners throughout the transition. Neither company is stepping back from SAF. With more than three decades of partnership behind them, Sasol and Topsoe are betting that a leaner structure — not a bigger one — is the right way to compete in a market that’s still finding its shape.
