SulNOx, the greentech company delivering lower fuel costs and emissions, at zero CAPEX, is pleased to announce that it has secured a further patent in Brazil.

Consistent with SulNOx's patents granted to date in other major markets, this latest patent covers a range of formulation versions which includes both the Berol® 6446 Heavy Sulphur Fuel Oils (HSFO) emulsifiers and SulNOxEco™ Fuel Conditioners which enhance all diesel, petrol/gasoline, biofuels, and marine fuels including Marine Gas Oil (MGO) and Marine Diesel Oil (MDO), Very and Ultra Low Sulphur Fuel Oils (VLSFO/ULSFO) and HSFO. 

Brazil is an important new patent for SulNOx, representing validation in the world's 10^th largest economy (Source: IMF) and the largest country in South America by area and Gross Domestic Product. It is the world's fifth largest by area and its seventh largest by population. 

SulNOx expects the patent to support its pursuit of partnerships and collaborations with major industrial groups in the region. In the mining sector, Brazil is among the largest producers of iron ore, copper, gold, manganese, tin and nickel. Coastal shipping links are also critical to the Brazilian economy, connecting widely separated parts of the country, which has 36 deep-water ports. Inland, the road system is the primary carrier of freight and passenger traffic, marking a third major sector facing significant decarbonisation challenges and targeted by SulNOx. In November 2025 the COP30 global climate change conference will be held in the Brazilian city of Belém.

Ben Richardson, CEO of SulNOx, commented: 

"Our Brazil patent adds a huge and diverse economy to a growing portfolio. There are few countries with so many industries operating on a large scale, each pursuing tough sustainability goals on tight timetables. We are excited by the opportunity to work with a wide range of sectors to deploy our products at scale, helping organizations to save fuel costs and reduce emissions rapidly with our zero-capex solutions."
