This guide presents how dredged sediments can be beneficially used in road engineering with a view to sustainable development and to the protection of the environment and of populations.

This is the result of research carried out by the Department of Civil and Environmental Engineering (DGCE) at the School of Mines of Douai for more than ten years on the theme of using dredged sediments. It is coherent with French regulations and the methodological framework (ADEME, 2010; SETRA, 2011) that prevailed at the time of the work.

This guide is not intended for use of sediments abstracted from a river system. It is only intended for harbour and canal dredgings, where restitution to river systems is usually not possible -at least economically.

On the occasion of the World Circular Economy Forum (WCEF), held on 4-5 June 2019 in Helsinki, the Architects' Council of Europe (ACE) published a Statement highlighting the importance of design to achieve more circularity in the construction and building sector, as well the solutions that architecture can bring.

Like many other sectors, the construction and building sectors operate largely within a linear economy model of “take, make and waste”. Yet, there is growing awareness of the finite nature of natural resources and fragility of our environment, and thereby of the urgent need to develop more sustainable and regenerative economic models.

Architecture has a crucial role to play here as many decisions taken during the design phase have long-lasting consequences on the environment.

Explore how city governments around the world are taking action to enable circular economy opportunities that deliver on a range of mayoral priorities, Sustainable Development Goals, and climate objectives.

1. Vision: What will the implementation of circular economy principles in cities look like?
2. Factsheets: What benefits can a circular economy transition in key urban systems bring to cities?
3. Policy levers: What can urban policymakers do to accelerate this transition?
4. Case studies: What examples are there of urban policymakers already putting this into action?
5. Other networks & resources: What are other organisations doing on the topic of circular economy and cities?

This book by ORÉE will help you discovering a large number of experiments and actions which can be reproduced on your level of action. Their generalisation to the whole France is currently a priority if we want to lead the ecological transition of our society. Nevertheless, circular economy is not something which can be decreed, and each territory wishing to invest in it has to reinvent its own process to adapt and implement the concept to its own specificities.
