A visit to Implenia site in Ecublens (VD) was performed to learn more about the asphalt manufacturing process and plant operation features. This recently overhauled plant is equipped with new technologies that aim at plant efficiency and therefore sustainability while improving productivity. This includes efforts to increase energy savings and reduce environmental impacts, improve plant versatility to better meet individual customer requirements and increase use of recycled asphalt in mixtures. The visit provided a good overview of the process requirements and pointed out current limitations and possible improvements areas for higher efficient and cleaner processes, some of them to be tackle in this project.
The following questions should be addressed by this project:
- How can we run an asphalt production site with the minimum amount of fossil high-density fuels?
- How can we increase the thermal efficiency of such a plant?
- How can we increase the amount of recycled asphalt in the whole production process?
Implenia as one of the project partners is seeking for optimised design solutions as they plan to overhaul existing Swiss production sites.
Outlook and next steps.
After the first identification phase, the project team is now moving into the exploration phase by synthesising the information gathered and by getting a deeper understanding of the user needs to achieve a problem customer fit.
