Great results from testing UPM’s wood-based diesel in buses

UPM has successfully tested Finnish wood-based diesel fuel both in laboratory conditions as well as in traffic. The tests clearly demonstrated that UPM’s renewable diesel, UPM BioVerno, works just like the best diesel fuels.

The laboratory tests of renewable UPM BioVerno diesel were conducted in the VTT Technical Research Centre (VTT) and field tests in Helsinki region bus traffic together with Helsinki Region Transport (HSL). The year-long bus field tests’ measurements were done by VTT, and the tests were also supported by Transdev Finland Oy, Volvo and St1.

The first laboratory tests were done with Euro III Class buses, which are still widely used on Finnish roads even today. UPM BioVerno diesel produced clearly lower emissions than fossil diesel. Compared to other advanced fuels, the emissions of UPM BioVerno diesel were at least as low as theirs.

“The use of UPM BioVerno diesel in the current bus fleet instead of fossil diesel would lower emissions from public transport significantly. This is good news as this Finnish wood-based fuel could immediately – and positively – affect the air quality in the Helsinki region,” says Sari Mannonen, Vice President of UPM Biofuels.

The field tests with buses were conducted by Transdev Finland on a regular bus route between the city of Kerava and Helsinki using four identical Volvo Euro VI Class buses that have low emissions and efficient engines. The test runs were done using 20%, 50% and 100% UPM BioVerno diesel and St1 was the fuel logistics provider in the tests.

According to test results, UPM BioVerno diesel is working very well in all blending ratios – just like the best diesel fuels – and fuel consumption was exactly the same. Together the four buses travelled some 400,000 km without any fuel-related incidents.

The Euro VI Class buses are equipped with diesel particulate filters (DPF) and selective catalytic reduction (SCR) catalysts which are capable of reducing emissions to a negligible level, so the tests did not show any significant differences in emissions between various fuels. In Euro VI Class engines the fuel affects the emissions mainly indirectly: high quality fuel, such as UPM BioVerno, guarantees that the exhaust cleaning systems operate effectively even after driving significant mileage.

“We are happy with the test results – they show that UPM BioVerno could fully replace fossil diesel in current bus traffic. Biofuels have a significant role in our company’s targets, as we are aiming for carbon-free public transportation in the Helsinki region,” says Reijo Mäkinen, head of the Traffic Services department in HSL.
