HVO100 renewable diesel - the health benefits of HVO100

Most conversations about HVO100 renewable diesel rightly focus on the fuel’s environmental credentials. Produced from renewable waste oils and fats, HVO100 can reduce lifecycle greenhouse gas emissions by up to 95% compared with conventional diesel. It can be up to 95% lower in lifecycle carbon emissions.

HEALTH BENEFITS OVER MINERAL DIESEL

There is, however, another benefit that receives far less attention but may be just as important for HVO100: its potential to improve human health and, more directly, employee health.

Unlike conventional diesel, HVO100 contains virtually no sulphur, aromatic hydrocarbons or other impurities commonly found in fossil diesel. It is a paraffinic fuel that burns more cleanly, resulting in significantly lower emissions of some harmful exhaust pollutants.

One of the greatest potential health benefits comes from the reduction in diesel particulate matter (DPM). These microscopic particles are small enough to penetrate deep into the

lungs and, in some cases, enter the bloodstream. Decades of medical research have linked long-term exposure to diesel particulate matter with respiratory disease, cardiovascular disease, reduced lung function and several forms of cancer.

In 2012, the International Agency for Research on Cancer (IARC), part of the World Health Organization, classified diesel engine exhaust as a Group 1 carcinogen – the highest category of evidence that an agent can cause cancer in humans.

Because HVO100 generally burns more cleanly than conventional diesel, numerous engine tests have shown substantial reductions in particulate emissions. Depending on the engine and operating conditions, particulate matter can typically be reduced by between 20% and 60%, with many studies also reporting reductions in carbon monoxide, unburnt hydrocarbons and, in some applications, nitrogen oxides (NOx).

These improvements are particularly important for people who work around diesel-powered equipment every day. Mining operations, transport depots, warehouses, construction sites, ports, rail yards and emergency power facilities can all expose workers to diesel exhaust for extended periods. Every reduction in harmful emissions contributes to a healthier working environment.

Communities also benefit. Trucks, buses, generators and construction equipment often operate in populated areas where diesel exhaust can affect nearby residents. Cleaner combustion means cleaner air for everyone – not only the operator of the vehicle.

HVO100 also produces noticeably less visible smoke and odour than conventional diesel. While the absence of visible smoke does not guarantee clean air, it is generally consistent with more complete combustion and lower emissions of soot and unburnt fuel.

Importantly, these potential health benefits require no changes to engines or infrastructure. HVO100 is a genuine “drop-in” renewable diesel that meets the EN15940 paraffinic diesel standard and can replace conventional diesel in many modern diesel engines without modification. Organisations can therefore reduce harmful exhaust emissions while simultaneously reducing greenhouse gas emissions.

HEALTH BENEFITS OVER BIODIESEL

While both HVO100 and biodiesel are renewable alternatives to conventional diesel, they are fundamentally different fuels with different combustion characteristics.

Biodiesel (FAME – Fatty Acid Methyl Ester) contains oxygen within its chemical structure and can reduce some emissions compared with fossil diesel. However, its properties can vary significantly depending on the feedstock and production process. Biodiesel can also have greater sensitivity to oxidation and may produce different emission outcomes depending on the engine, blend level and operating conditions.

HVO100 (Hydrotreated Vegetable Oil), by contrast, is a paraffinic renewable diesel produced through a hydrotreatment process that removes oxygen, sulphur and other impurities. The result is a clean-burning fuel with a chemical structure very similar to premium fossil diesel, but without many of the contaminants associated with conventional diesel.

For health and workplace exposure, this difference is important. HVO100 typically produces lower particulate matter (soot), lower carbon monoxide and lower unburnt hydrocarbon emissions than fossil diesel and, in many applications, biodiesel blends. The absence of aromatic compounds also contributes to cleaner combustion and can reduce the toxicity of exhaust emissions.

For industries such as mining, transport, construction and manufacturing – where workers can spend thousands of hours around diesel equipment – the choice of fuel can directly influence air quality. HVO100 provides organisations with an immediate pathway to reduce harmful diesel exhaust exposure while maintaining the operational reliability expected from modern diesel engines.

Both biodiesel and HVO100 have a role to play in the renewable fuel transition. However, when the objective is cleaner combustion, improved air quality and a genuine drop-in replacement for conventional diesel, HVO100 offers significant advantages.

No fuel completely eliminates exhaust emissions from an internal combustion engine, and HVO100 should not be viewed as a substitute for proper ventilation, emissions controls or sound workplace safety practices. Nevertheless, reducing harmful pollutants at their source is one of the most effective ways to improve air quality.

For many organisations, the transition to HVO100 is not simply an environmental decision. It is also an investment in cleaner air, healthier workplaces and reduced exposure to one of the world’s best-recognised occupational hazards.

Cleaner fuel does more than reduce carbon emissions. It can also help protect the people who work with diesel every day.
