Greenrail is a sustainable railway sleeper made of a concrete inner core with an outer shell made of recycled plastic and End of Life Tyres (ELTs).
Every kilometre of railway line armed with Greenrail sleepers can recover up to 35 tons of ELTs and recycled plastic.
The railway sector hasn’t been innovated during the past 50 years and nowadays 80% of the global sleepers are still made of pre-stressed concrete.
The concrete sleepers present several weaknesses such as high rigidity, inhomogeneous pressure distribution between the lower contact surface of concrete sleeper and the ballast, high pulverization of ballast, low resistance to lateral displacement high noise, high vibration and high maintenance costs.
Greenrail represents the solution for the listed problems.
As a matter of fact, Greenrail sleeper is able to reduce the rigidity, the vibration and noise, the ballast pulverization and to lengthen the lifespan cutting the maintenance costs.
Furthermore, Greenrail, thanks to the outer shell made of second raw materials, is contributing to the Circular Economy principles’ development, following also the European directives, which are driving the transport sector to a new sustainable mobility.
Greenrail is the only sustainable sleeper able to integrate smart technologies for harvesting energy and communicating the diagnostic data.
The overall objective of the project is to make Greenrail sleepers become the new sustainable standard in the railway sector, offering technical, environmental and socio-economic advantages.
Thanks to the SME Instrument Phase 2 funding, Greenrail has produced and launched onto the market the Greenrail Basic, finalizing the first licensing contract with an American company.
Furthermore, the first prototypes of Greenrail Solar, LinkBox and Piezo have been produced and laid on field for the dedicated pilot site and demonstration activities. The results of the tests conducted on the two pilot sites have been collected in the last two deliverables produced by Greenrail showing the potential of Greenrail Basic and Greenrail smart sleepers.
