This case study will focus on the role of decarbonising road maintenance in the transition to a circular economy. A whole systems approach (energy and asset management) will be undertaken to explore the plans and strategies currently in place to reduce the negative impacts of maintenance operations by continuous improvements such as energy efficient materials and working practices as well as the contribution that could be made by generating clean energy from currently ‘unproductive’ road infrastructure to offset residual emissions.
We will use the framework from WP3 to assess energy management within the context of maintenance operations, identify gaps in knowledge and processes and evaluate the potential to boost circularity.
