The University of Twente has opted to use 1400m2 of Grasfalt® and Lynpave® asphalt for the installation of Witbreuksweg, the road around the car park also known as the bus station. This decision to use Grasfalt® aligns with our sustainability objectives very well.
How does CO2 reduction work?
The decision to use Grasfalt® and Lynpave® means that 25 more tons of CO2 will be absorbed during the installation of Witbreuksweg than will be emitted during the entire production process. The base and binder layer of the asphalt consists of Lynpave® asphalt. Lynpave® asphalt reduces CO2 emissions by 20% during the production process thanks to the addition of linseed oil and a lower production temperature. The surface layer of Witbreuksweg will consist of Grasfalt®.
What is Grasfalt®?
Grasfalt® is an innovative type of asphalt in which bitumen is replaced with a biobased binder material made of lignan derived from elephant grass. Fewer primary raw materials such as bitumen are therefore required. The use of lignin instead of bitumen means the asphalt can be produced at a lower temperature, thus reducing CO2 emissions by 20% In addition, the planting of elephant grass allows a considerable amount of CO2 to be absorbed and stored during growth. This makes the asphalt considerably more sustainable.
Installation of sustainable asphalt on 9 April
NTP, our contractor, will install the sustainable asphalt at Witbreuksweg on 9 April.
