Are you interested in contributing to knowledge development of pioneering new business models for scale-able and circular impact for infrastructures? Then we are looking for you!

Job description

For a public and privately funded partner program called The Circular Road, we are looking for a Postdoc with 0,6 and 0,8 FTE appointment for a maximum duration of 3 years (of which first a 1,5 year contract and a possible extension upon good performance).

The construction sector is transitioning to circular practices, in which it uses raw materials as efficiently and circularly as possible in projects. To make this feasible and self-reliant, the sector is actively seeking the potential of new circular business models. The Circular Road partner program has been a frontrunner in this endeavour in the Netherlands. Since 2020, the first partner program developed the As a Service concept based on the practical needs and scientific input. In this stage, various practical products have been delivered by public and private partners (such as practical manuals, calculation models and advisory reports) as a toolkit to the implementation of As a service models in infrastructure works. As a partner, the TU Delft has helped to develop these As a Service models and tested the added value on concrete infrastructure cases. This proved that these models achieved some promising results both on the environmental and behavioral sides of circularity.

In 2024, the time has come to look at the circularity and scale-up potential of these models with a renewed set of partners and pilots. The main question for this phase of the research will be “With which choices in Infra As a Service models do parties achieve more circularity and scaling potential for infrastructure projects?” A few particular challenges will have to be overcome in this project. First, there is the challenge of measuring circularity amidst an infant circular data structure. Second, the level of accessible knowledge to the workings of the as a service model, need to be improved.

In pushing for solutions to these challenges, the research will also address a number of sub-questions using the existing and new pilot cases, like:

  • Which as a service request, design and financial model result in which sustainability measures?
  • Which incentives in the existing As a service projects result in which sustainability and circularity measures? And which of these incentives can be specifically influenced and used by the public client?
  • What is needed in the AAS model to get a positive business case for everyone involved?

In a possible extension of your contract, you will follow-up on assessing the circularity and scale-up potential of as a service models in comparison to existing mechanisms at the disposal of public agencies in the Netherlands and internationally. This involves sub-questions like:

  • How effective is the as a service model on circularity and scaleable impact in comparison to other forms of public-private collaboration (e.g. two-phase contracts, program contracts, rapid circular contracts, innovation partnerships)? What considerations will play a role for public clients when it comes to choosing between these forms?
  • What is the circularity and scale-up potential of implementing as a service models in other international contexts where infrastructure is publicly procured (like the other countries in the European Union)?
