Eminox part of winning partnership at HS2 awards

Eminox, is delighted to have been part of the team that scooped ‘Winning Paper’ in the Technical Papers Competition, Environment and Heritage category at the recent HS2 Learning Legacy Awards.

In partnership with HS2 Ltd, Balfour Beatty, Vinci and Imperial College London, James Thorpe and Niki Welch from Eminox were part of the project and subsequent paper entitled ‘Reducing Emissions in Construction: Non-Road Mobile Machinery’.

“This is a superb achievement for us all and reflects the complexity of the work we do to reduce emissions of Non-Road Mobile Machinery (NRMM) to improve air quality and protect public health. It has been a pioneering project to work on; one which has created a blueprint for the construction sector to showcase how equipment can be upgraded to achieve Stage V equivalent emissions standards, reducing carbon footprint and maximising the lifespan of equipment. HS2 should be acknowledged for setting the standard and leading the way to show that major infrastructure projects can be completed whilst adhering to the latest emissions standards in a cost-effective way.”

“We are proud to have set industry leading emissions standards for all machinery, and for our EMx S5 system to be the first solution successfully approved by the Energy Saving Trust. Now that this is included in their NRMM Retrofit Accreditation Scheme, more businesses can take advantage of the system to achieve Stage V equivalent emissions standards.”

said Carlos Vicente, Retrofit and Aftermarket Sales Director, Eminox.


The research paper reported the collaboration of the partners activities which successfully reduced nitrogen oxides (NOx), particulate matter (PM), and embodied carbon across its operations. The exhaust aftertreatment retrofit solutions were fitted and trialled on a piling rig and rotary rig.

The systems were tested to quantify the emission saving potential of the exhaust aftertreatment systems which delivered more than 90% reduction in harmful emissions. Furthermore, the paper estimates a saving potential of £60m in plant capex to date and over £300m for the entirety of the HS2 project.
