Eco-construction of a wooden-made and bioclimatic operations building at Aubevoye’s water treatment plant
Aubevoye’s water treatment plant meets the requirements of the innovative HQE process, offering a bioclimatic operations building with a Douglas pine tree wooden frame. The natural and high performance materials used enable a safe, comfortable and long-lasting construction which is also positive-energy thanks to a photovoltaic roof. The building is oriented on a North/South axis, benefiting from an optimal sunshine over the winter, while in summer the heat is dissipated thanks to the dual-flow ventilation system and the sun-breaker devices on the roof. The building is...
Towards sustainable airport areas
In a context of increasing globalisation of trade, increasing international flows of goods and people, and the resulting global increase in air traffic, international airports are strategic assets for the development and attractiveness of the countries and territories that host and serve them. International airports and their surrounding areas are of increasingly strategic importance for the development of the metropolitan regions they serve. They are also evolving and becoming distinctive economic and urban places in their own right. At the same time, airport activity has a significant...
« Villes, numérique et innovation sociale : expériences françaises »
Over recent years, we have witnessed the constant growth of urban density all around the world: according to the United Nations (UN), around 70% of the world’s population will live in cities by 2050. This global phenomenon is associated with numerous challenges, such as sustainable development and air quality, the transformation of transport and mobility, the preservation of public services, access to health care and the promotion of living better together.   In this publication, France urbaine, an association bringing together major cities, inter-municipalities and...
The regional food project of Caen Normandy Metropole
Caen Normandy Metropole’s regional food project was launched in October 2017. For one year, a participatory approach involving all the regional players led to the development of strategic guidelines that were recognised by the National Food Programme (NFP) label in February 2019.   By organising thematic workshops and field visits locally (urban farm, wholesale market, association providing work in market gardening, farmer allowing individuals to do their own picking, canteens offering vegetarian menus and so on), stakeholders in the Caen region now have a...
Recyclean®: an exclusive process for reusing polluted roads
The circular economy is crucial for the future of construction because it helps preserve resources and better manage waste. It is fully in line with the ecological transition and innovation, two of the pillars of Eiffage's strategic plan.   So Eiffage Route has developed Recyclean®, an exclusive process for reusing polluted roadways, including polycyclic aromatic hydrocarbons (PAHs), which is fully part of this strategy. Recyclean® allows this type of roadway to be regenerated and existing materials to be reprocessed. This solution generates no waste or landfill...
Industrial demonstrators for the sustainable city: Rêve de Scènes Urbaines
The industrial demonstrator for the sustainable city Rêve de Scènes Urbaines (Dream of Urban Scenes), led by VINCI, Véolia and Artelia, offers an original approach with cooperation between public and private stakeholders in the city to experiment and produce innovative urban solutions. It is initially part of a constantly changing region, Plaine Commune, itself located in the heart of Greater Paris.   To function, the demonstrator relies on an open ecosystem whose objectives are to implement: a partnership platform for urban innovation, a...
Trilib', self-service waste sorting
To allow more Parisians to sort their waste more simply and be able to provide a solution to the 10% of Parisians who do not have a yellow bin, Citeo conducted and financed an experiment in Paris: 40 trilib' stations, local collection containers available 24 hours a day, located in 4 districts. Modular urban sorting furniture, the trilib' station brings together 5 streams: glass and metal packaging, plastic bottles and containers, paper and cardboard, and finally, textiles. Digital innovation and user service, station filling rates are available in real time on the opendata....
Caen, nature city
Eighteen kilometres from the sea, at the confluence of the Orne and the Odon, Caen is most definitely a city between sea and nature. Structured by a partially channelled coastal river, the city was heavily affected to the north by the metallurgical industry, while preserving to the south direct access to nature by its vast flood meadow that goes right into the heart of the city. Today known for its agricultural plain and the quality of its limestone, Caen actually draws its identity from Normandy’s rivers and meadows, making it a city naturally structured by its green...
ActivSkeen: an energy-producing building envelope
Because tomorrow is being built today and building is at the forefront of the energy transition, the fight against climate change and changing lifestyles and work, ActivSkeen creates solutions with facades and active, aesthetical envelopes that reduce the building's environmental footprint and improve occupant comfort.   So it is no longer about installing a façade element providing the functionality of waterproofing, insulation and ventilation, but an element producing, in addition to these basic features, energy. ActivSkeen uses built-in photovoltaic technologies...

Smartseille, the eco-neighbourhood of the future to live in the present
The City of Marseille and the Euroméditerranée public institution are carrying out the largest urban renewal operation in Southern Europe in the northern districts of the city. It is within this context that "smartseille", the eco-neighbourhood project designed by Eiffage, was born: 58,000 m2 were built on 2.7 hectares by harmoniously combining housing, offices and services while offering housing and offices at affordable prices and easy access to all new technologies. This 21st century eco-neighbourhood also provides its inhabitants and users with the best sustainable...
WEECAM project: implementation of a sustainable W3E recovery sector in Cameroon
Solidarité Technologique is a French association working in Yaounde in the field of vocational training for disadvantaged young people and the recovery and recycling of waste electrical and electronic equipment (W3E). W3E is a category of waste that poses a dual problem: rapid growth and significant management constraints in view of certain toxic components. Developing countries are particularly exposed to this problem: their rapid economic and demographic growth, as well as the social and cultural changes brought about by such development, are leading to a sharp increase in...
