Industry Sectors

Consumers of hydrocarbon liquid fuels should consider incorporating SulNOx as part of decarbonising and cost saving responsibilities. To find out how SulNOx can play an integral part in helping your industry reduce emissions, reduce costs and meet its ESG goals, select from the list of sectors below or contact us for more information.


The transportation sector accounts for 25% of global emissions, 75% of which are from road transport. Immediate actions to increase fuel efficiencies have been outlined by world leading authorities to reach climate goals.

SulNOxEco™ Petrol Conditioner & SulNOxEco™ Diesel Conditioner significantly increase fuel efficiencies of light fuels including gasoline, regular diesel, Marine Diesel Oil (MDO), Marine Gas Oil (MGO), Biofuels including Hydrotreated Vegetable Oils (HVO) and Kerosene.

SulNOxEco™ Petrol Conditioner & SulNOxEco™ Diesel Conditioner are made with natural, biodegradable ingredients, and comply with the strictest global road fuel standards for various blends of petrol and diesel. Both products provide a simple no-risk, cost-saving solution to decarbonisation.

Savings of 8-10% have been achieved in extensive commercial road fleets.

Fossil-based liquid fuels make up more than 98% of fuel in the ‘hard to abate’ marine and shipping sector with little change anticipated over the short to medium term.

SulNOxEco™ Diesel Fuel Conditioner provides an immediate cost-saving and decarbonising solution by increasing fuel efficiencies of marine diesels, MGO/MDO, biofuels and ULFSO/VLFSO.

Long-term stable emulsions of all grades of HFO using Berol® 6446 Fuel Emulsifier and Ultrasonic process equipment to emulsify up to 18% additional water, provide significant fuel and maintenance savings and reductions in toxic emissions.

Fuel Storage and Distribution

Over time, stored fuel can suffer from an accumulation of sediments, bacteria, fungi and problems like Diesel Bug. This may lead to costly remedial measures, waste and engine damage, particularly amongst infrequently used marine vessels.

Diesel Bug and other microbial problems occur when a build up of water in fuel, through condensation and other means, separates out from the fuel, providing a growth medium. Increasing use of bio-content in fuel magnifies the problem due to its hygroscopic nature – encouraging further separation. SulNOxEco™ Diesel Conditioner helps eliminate this problem by dispersing the troublesome water in fuel therefore removing the environment for microbial growth and Diesel Bug, whilst enhancing fuel quality and adding stability.

Oil Reclamation

Ship operations including tank cleaning, purifying fuels and use of ballast water produce industrial waste oil and water emulsions, commonly referred to as “ship slops”. These are predominantly composed of water (c. 70%) and liquid hydrocarbon products, including Heavy Fuel Oil (HFO) and cargo waste e.g. Crude Oil (c. 30%).

SulNOx has an improved process for the separation of the oil from this waste. Our process takes the harmful oil and water waste and purifies it within a matter of hours. Reclaimed oils using our process show as little as 1.5% moisture content in independent testing by Bureau Veritas, whilst gaining lubricity and remaining stable. The dramatically lower water content improves value and saleability from its increased number of uses. The remaining water layer is also far easier and cleaner to dispose of in an ethical and environmentally sustainable manner.

Mining vehicles and machinery have intensive workloads with significant fuel consumptions.

SulNOxEco™ Petrol Conditioner & SulNOxEco™ Diesel Conditioner optimise combustion significantly reducing fuel usage and production of greenhouse gases. Independent tests show reductions in Particulate Matter (PM10 and PM2.5) by over 50% and 60% respectively, greatly improving air quality and damage to health, particularly importantly in underground and enclosed mining situations.

Power Generation

Generators have intensive workloads consuming large amounts of fuel (usually diesel) often providing the backbone for mining, construction and events sectors.

In many parts of the world, diesel power stations are still in use. SulNOxEco™ Diesel Conditioner optimises combustion significantly reducing fuel usage and independent tests in generators have shown reductions in various greenhouse gases of between 20-30% and Particulate Matter (PM10 and PM2.5) by over 50% and 60%.


The Agriculture sector often relies on stored fuel for powering machinery and vehicles.

SulNOxEco™ Diesel Conditioner resolves fuel storage problems often caused by water contamination in fuel, magnified by increasing bio-content, leading to problems such as ‘diesel bug’ which can damage engines. When the ‘conditioned’ fuel is used, optimised combustion provides significant fuel and maintenance savings and reductions in emissions.


The construction industry is a large consumer of fuel, primarily diesel, with a mix of power generators, heavy plant and machinery and on/off road vehicles in use.

SulNOxEco™ Diesel Conditioner complies with the strictest fuel specifications and provides a no risk solution to reducing fuel and maintenance costs and emissions through optimised fuel combustion. Extensive commercial road tests have shown 8-10% in fuel savings. Independent tests have shown reductions in various greenhouse gases of between 20-30% and Particulate Matter (PM10 and PM2.5) by over 50% and 60%, respectively, important to reduce risk to workforce health.
