Welcome to our world of net  zero biofuels. Around the globe, governments and businesses have realised that we have to stop using environmentally damaging fossil fuels, and here at Neutral Fuels we have the solution. We’ve been doing it net  zero since 2011.

We were the first company to pioneer 100% pure compliant biofuel made from used cooking oil to cut the damaging greenhouse gas emissions that cause climate change. In the process we’ve proven the commercial viability of biofuel.

And then we've gone even further. We've surrounded our fuel with an unprecedented level of technology so brilliant it tells our customers everything they need to know about managing their transportation fleets. Our net zero fuels actually save customers time and money.

With our fuel, no engine modifications are necessary and there are no changes in fuel efficiency and no added expenses. There is simply the added bonus of engines that perform better and last longer... and, of course, a much healthier planet.

Tech is in our DNA. Based on three decades of experience in developing and deploying 100% useful software, our iFuel app and back-office Neutral Exception Technology offer intelligent options to improve your net zero biofuel consumption and fleet efficiency, setting a new standard for fuel management. It’s a completely new way to manage your fuel usage for our net zero biofuel world.

& optimising

Not content only with managing fuel usage, we also integrated our novel oil collection system, which uses a custom 100% reusable oil container, with a cloud-based data portal. This enables us to track and trace every drop of used cooking oil, ensuring a 100% complete audit trail.

This means we can provide our suppliers with valuable quantity and chemical quality data, allowing them to optimise operating costs.

From day one we have used more tech, more IT, and more software in the creation of our net zero biofuel than any other company in our industry, improving the way fuel usage and budgets are managed.

Together we can save the planeT

Our net zero biofuel is really net zero. For every drop of fuel we produce, we plant the precise number of trees needed to fully offset the impact of our operations. Our net zero biofuel takes your fuel carbon footprint to zero, and reduces local smog, soot and other tailpipe emissions by up to 50%. This is how we contribute significantly to ensuring the survival of our species, one net zero drop at a time. Read about our Net Zero Reforestation Programme.
