City of Lahti wins international recognition for the use of asphalt based on recycled material

The municipal engineering department of Lahti has been selected runner up for the Procura+ innovation procurement of the year award.

​The City of Lahti has undertaken a pilot for more sustainable and circular road construction, using asphalt produced from waste roofing felt for demonstration roads within the city. This supports Lahti's ambitious circular procurement goals.

The reuse of old bitumen sheets decreases the carbon footprint and carbon emissions of asphalt production by 10%. It also reduces a waste handling problem, with roofing previously deposited in landfills or combusted. The pilot was carried out in conjunction with the Finnish Transport Agency, who will now consider the circular solution for future procurement processes in the region. This has potential to save 6,000 tonnes of CO2 per 100,000 tonnes of asphalt produced.

The Procura+ award was granted by European public authorities' sustainability network ICLEI

On 17 October 2017, the City of Lahti was recognised for an innovative public procurement that promotes circular economy in road construction. The recognition was awarded for the use of crushed bituminous roofing felt in the production of asphalt on one pedestrian and cycle route and three driveways in Lahti. The solution was implemented by Tarpaper Oy.

The Procura+ innovation procurement of the year award was granted by ICLEI – Local Governments for Sustainability, a worldwide organisation of municipalities and cities with more than 1,500 members. ICLEI is tasked with supporting local governments in identifying sustainable, low-carbon resource-efficient solutions. Procura+ is a network within ICLEI focussing on procurement. Since 2015, it has annually granted the Procura+ Award.
