Bachy Soletanche are very proud to announce they have taken home two prizes at the VINCI Environment Awards: The Grand Prize for an equipment emissions reduction programme and a Special Jury Prize for the development of a steel cage tamp.
The VINCI Environment awards, in their inaugural year, encourage the development of sustainable practices both within the Group and across the industry, as VINCI strive to become world leaders in environmental innovation.
The Grand Prize was awarded to a joint entry between Bachy Soletanche and Cybrand for the development, implementation and independent approval of an exhaust after treatment system for larger diesel engines fitted into our construction machinery (above 300kW). This innovative solution features a retrofitted diesel particulate filter and selective catalytic reduction system, which significantly reduces the engine emissions. Diesel engines of this kind produce pollutants that damage our health, environment and ultimately, our climate. Replacing older machines with new equipment requires huge time and investment so the team wanted to find a way of extending the life in the UK of some of our older equipment by reducing the pollutants from their diesel engines.
Working with the supply chain, the team identified that retrofitting the diesel particulate filter and the selected catalytic reduction system would reduce pollutants and allow the machines to achieve a higher level of emissions compliance taking the original engine from meeting Stage IIIA requirements to achieving most up to date Stage V.
The environmental solution garnered impressive results,
reducing carbon monoxide by 90%, particulate matter by 99%
and nitrogen oxide by 97%.
A further benefit is that at the end of its life in the UK, this machine can now be responsibly recirculated elsewhere in the world, polluting significantly less than it would otherwise have done. Bachy Soletanche believe that whilst this technology is not new, this was the first application in an engine above 300kW.
Bachy Soletanche is currently upgrading a number of older engines within their fleet with this solution. The judges were impressed by their practical and effective solution, significantly reducing harmful emissions from the older diesel engines that are still in use around the UK.
