Background and motivations
The current dominant linear development model, based on the triptych ""Extract, Produce, Throw away"", has reached its limits and demonstrated its inability to ensure the sustainability of the economy and the species within a finite planetary system. A paradigm shift is required to address ecological and climate challenges. The circular economy, inspired by the functioning of natural ecosystems, is today a credible alternative, based on the creation of positive value loops linked to the reuse of resources (water, energy, air), materials or products, following a logic of transformation and regeneration avoiding destruction and the production of waste. The circular economy focuses on new ways of designing, producing and consuming, on extending the life of products, on using rather than owning goods, and on reusing, reclaiming and recycling components.
However, the circular economy  has logistical impacts in its implementation, which are either manifested in terms of:
•changes in flow volumes (e.g. by reducing the amount of materials needed for reuse, recovery and/or recycling, or by developing eco-design and packaging-free products),
•the geography of flows, in connection with the relocation of certain supplies or the development of necessary intermediate storage and recovery sites,
•flows organization to ensure that the outputs of one activity are converted into inputs for another at the right time, in the right quantities and at the best cost.
The PhD thesis proposed here focuses on these logistical impacts, which are often overlooked and yet condition the success (or failure) of circular economy initiatives. These new models deserve to be taken into account, especially in dense urban areas where the flow of goods is already significant . It is therefore necessary to examine the impact of the deployment of the circular economy on the flow of goods, and consequently on congestion and other externalities. But it is also necessary to shed light on how to optimize the logistics of the circular economy to ensure the success of initiatives.
To answer these questions, it is necessary to represent the logistical demand inherent in the development of the circular economy (in terms of flows, space, and organization: origin and destination of flows; frequency; quantities) and the impacts in terms of economic and environmental costs of different deployment scenarios. Do these impacts cancel out the estimated environmental gains? Is it possible to set up virtuous logistics systems?
The objective of this PhD thesis is to assess the logistical impact of circular economy models. To this end, we intend to model the logistics and transport demand associated with circular economy strategies in a few territories, and carry out a simulation of the impacts of different circular economy deployment scenarios.
A central issue is to quantify the flows linked to the development of the circular economy for consumer goods, and to compare them with the volume of flows resulting from linear economy models. On the other hand, it will be necessary to test the evolution of the volumes of these flows, but also of the land requirements or the organization of the chains (origin-destination; frequency...) according to different scenarios of development of this circular economy, including public policy actions, and finally to evaluate the environmental and economic impacts of these scenarios, taking into account the logistic aspects.
This PhD thesis is part of a resolutely multidisciplinary framework. It will articulate economic sciences first, a model will be proposed for the representation and quantification of logistic flows, as well as the associated costs (economic, ecological, etc.); with contributions in computer sciences, with the multi-agent modelling and simulation of activities and logistic flows. The use of multi-agent modelling allows a differentiated representation of actors in the system (different profiles, different preferences, different decision mechanisms, etc.) and the observation of collective emergent behaviour. Multi-agent simulation is now a mature field with proven and effective platforms, some of which integrate tools specific to transport and mobility (Repast , MATSim , etc.).
This PhD thesis will be co-directed by Mahdi Zargayouna, HDR research fellow at Gustave Eiffel University for the computer science aspects and Corinne Blanquart, research director at Gustave Eiffel University for the economic aspects.
