When did Sulnox announce the European patent?

Sulnox announced the patent on 23 October 2025. The announcement concerns intellectual property protection covering 39 European countries.

What does Sulnox’s “Sulnox Reclaim” patent cover?

The patent covers an improved oil/water separation methodology developed by Sulnox. The methodology incorporates Sulnox’s patented green emulsification technologies and is intended to support the reclamation of useful heavy fuel oil from oily wastewater.

How could Sulnox’s patented process be used in the maritime industry?

Sulnox says its process could help address “ship slops”, which are oily wastewater produced by operations including tank cleaning, fuel purification and ballast water management. Ship slops typically contain around 70% water in what would otherwise be useful heavy fuel oil.

How does Sulnox’s process compare with traditional fuel oil separation methods?

Sulnox says traditional separation can require high heating temperatures and long separation times, while augmenting an existing separation plant with its process can reduce a typical 10-12 hour process to approximately three hours. The company also says lower temperatures are required, which can reduce heating requirements and the CO2 footprint.

What water and oil quality outcomes does Sulnox report for its separation process?

Sulnox says the recovered water is cleaner and may be disposed of easily. It also says recovered oil typically has less than 1.5% water content, compared with traditional recovery that can still contain 5% and above, which the company says can reduce the oil’s value and usefulness.

What earlier patent protection does Sulnox have for its fuel reclamation methodology?

Sulnox says the methodology was first recognised by a company patent in Nigeria earlier in 2025, followed by a Eurasia patent covering eight key jurisdictions. The European patent is described by Ben Richardson, Sulnox’s CEO, as the company’s third fuel reclamation patent.

How many markets does Sulnox say are covered by its wider patent portfolio?

Sulnox says it has additional patent protection in 50+ markets, including all major economies. The company says these patents cover a range of formulation versions for liquid hydrocarbon fuels and marine fuels.

Which fuels does Sulnox say its wider patent portfolio covers?

Sulnox says its patent portfolio covers formulations that enhance diesel, petrol/gasoline, fuel oils and biofuels. It also lists Marine Gas Oil, Marine Diesel Oil, Very and Ultra Low Sulphur Fuel Oil, and HSFO.

What is Sulnox’s business and how does it describe its offering?

Sulnox describes itself as a greentech company delivering lower fuel costs and emissions at zero capex. Its patent portfolio includes technologies for fuel treatment and fuel oil reclamation, including the “Sulnox Reclaim” product.

What does Sulnox say about the market opportunity for fuel reclamation?

Sulnox says ship slops are a feature of ship operations in ports worldwide and describes tackling them as an additional and sizeable revenue opportunity in the global maritime industry. The company also says demand for eco-friendly demulsifiers is supported by environmental regulation and a corporate imperative to adopt more sustainable practices.

What growth is estimated for the global demulsifier market?

The global demulsifier market is estimated to grow from US$2.4bn in 2024 to approximately US$3.2bn by 2031, according to VMR as cited by Sulnox.

What did Sulnox’s CEO say about the purpose of the European patent?

Ben Richardson, CEO of Sulnox, said the European fuel reclamation patent supports and accelerates the company’s strategy of diversifying its sources of revenue. He also said Sulnox is pursuing further expansion of its patent portfolio as it targets new sectors and markets worldwide.
