The objective of the project is to investigate whether secondary materials produced from residual plastics and plastic packaging waste generated in Estonia could be used in asphalt mixtures either as a substitute for bitumen or as an additive to improve asphalt performance.
The topic is particularly relevant because the use of fossil-based bitumen in asphalt production has a significant environmental footprint.
“Approximately one million tonnes of asphalt mixtures are produced annually in Estonia, requiring around 55,000 tonnes of bitumen. Every percentage point of substitution would significantly reduce both the amount of imported bitumen and the environmental footprint of the final asphalt product,” said Mart Arusoo, Head of the Construction Unit in the Development Department of the Transport Administration.
There is also a need to find additional high-value applications for recycled plastic materials in order to reduce the environmental impact of plastic consumption. Currently, only a portion of the residual materials generated during plastic recycling is utilized, mainly in the production of new plastic bags and waste bags.
“Until now, no suitable application has been found for the residual plastic generated during the recycling process. However, in our assessment, this material could potentially be well suited for use in asphalt mixtures,” Arusoo added.
If the innovation project proves successful, Estonia will be able to make use of low-value materials generated from the recycling of locally available plastic waste, including the increasing volumes expected as a result of future waste management reforms. A residual product that is currently incinerated could potentially become a valuable raw material for locally produced asphalt mixtures, replacing fossil-based bitumen and/or extending the service life of asphalt pavements.
The project will run until January 2029, followed by a five-year monitoring period. The total budget of the project is €788,500 and is financed by the Government Office’s Public Sector Innovation Fund.
The latest call of the Public Sector Innovation Fund focuses on strengthening national resilience, supporting economic growth, and creating a more efficient public sector.
