Oxonica Achieves Important Further Performance Validation for Envirox and Commercial Progress
(Nanowerk News) Oxonica plc (“Oxonica”), a leading international nanomaterials group, today is pleased to
announce an important further validation of its Envirox™ fuel borne catalyst by Stagecoach
Group plc (“Stagecoach") as well as positive test results and significant commercial progress
in mainland Europe and Russia.
Stagecoach originally tested Envirox™ in 2004 in an industry leading trial on 1300 vehicles
split between the North-west of England and London over a 12 month period. The trial
demonstrated fuel savings of more than 5% following which Stagecoach adopted the product
across its UK fleet. At the time of adoption, the parties also agreed to carry out a validation
trial to confirm continued product performance within 3 years.
In the second half of 2007 a validation trial was conducted on more than 550 Stagecoach
vehicles in the North-west of England. This trial has demonstrated a statistically significant
fuel saving of 4.3% after 3 months, which is consistent with the results from the original 2004
trial at the same point.
Stagecoach has indicated that it is satisfied with the results and intends to continue to use
Envirox™ across its 7,000 vehicle UK bus fleet.
Adrian Havlin, Stagecoach Group Technical Engineer said: ‘Stagecoach is in the front line of
tackling climate change through a range of initiatives, from biofuels and cleaner engines to
the introduction of modern environmental management systems. The use of Envirox™ is part
of our package of innovative solutions to build a more environmentally sustainable business
and encourage greener travel’.
‘Our vehicles have driven more than 700 million miles on Envirox™, and to achieve a
consistent result across a diverse fleet over 3 years testifies to the robustness of the
technology. We are particularly pleased with the performance of the product both in ultra low
sulphur diesel and in blends containing biodiesel, which are now in widespread use across
In addition to the successful Stagecoach validation trial, Envirox™ has achieved further
positive test results and has made significant commercial progress in mainland Europe and
A recently completed bus trial in Italy demonstrated fuel savings of 4.8% after 3
months and 10.6% after 6 months. Other trials in Germany on tour coaches and municipal mixed fleets have demonstrated savings of 5 to 8%.
Oxonica has recently completed an additional piece of work in collaboration with
Stagecoach at a major, independent, vehicle testing facility in the UK that
demonstrated reductions in particulate emissions of 18% after 3 months. An
independent vehicle laboratory test in Italy also showed reductions in particulate
emissions of up to 19%.
Oxonica has recently concluded two major distribution deals for Envirox™ in
Germany and Russia, both of which have already generated initial sales in 2008.
Dr Kevin Matthews, CEO of Oxonica said, ‘The evidence for the performance of Envirox™ is
becoming increasingly compelling at a time when the issues of climate change and high fuel
costs are becoming acute. This proven technology offers the potential to make a real
difference to carbon dioxide emissions today. In the UK, reducing diesel fuel use by 5% will
save 3 million tonnes of carbon dioxide per year, and Envirox™ can achieve this while, at the
same time, reducing the burden of high fuel costs on the transport sector’.
Richard Farleigh, Chairman of Oxonica said: ‘The UK is committed to reducing carbon dioxide
emissions and huge sums are being invested in future technologies that may be too little too
late. Action needs to be taken now and once again Stagecoach has demonstrated its
industry leadership in addressing environmental issues through its use of Envirox™ and
continued support for trialling and testing of the product. Envirox™ clearly provides immediate
benefits to the environment while more than paying for itself through fuel savings.’
