FastCarb: storing CO2 through carbonation of recycled concrete
Le projet de recherche FastCarb (Stockage de CO2 par carbonatation du béton recyclé) est coordonné par l’Ifsttar et bénéficie d’un soutien du Ministère de la Transition Ecologique et Solidaire. Il est porté par l’IREX et comprend, fin décembre 2017, 17 partenaires qui ont signé la charte du projet. Actuellement, les granulats de béton recyclés (GBR) sont traités soit par l’enfouissement, soit en matériau de terrassement à faible valeur ajoutée. En parallèle, les granulats naturels sont une ressource non renouvelable, de plus en plus difficilement accessible pour des raisons sociétales et environnementales. Les travaux du PN Recybéton...
The FastCarb research project (CO2 storage through carbonation of recycled concrete) is coordinated by IFSTTAR and benefits from the support of the French Ministry of ecological and solidarity transition.
 
Carried out by IREX, it included, at the end of December 2017, 17 partners that have signed the project’s Charter. Currently, recycled concrete aggregate (RCA) is treated either by landfilling or by being turned into low-added-value landscaping materials. Meanwhile, raw aggregates are a non-renewable resource, which are less and less accessible owing to societal and environmental reasons.
 
The “Recybeton” National Project’s works have enabled better management of the formulation of concrete including a high percentage of RCA. It is now necessary to improve the performance of RCA.
 
The FastCarb project is about validating - theoretically and experimentally - the technical concept of RCA’s accelerated carbonation through different methods. Downstream, the objective is to design and implement an accelerated carbonation process at industrial scale and to define its environmental and economic sustainability.
"Reduce the ecological footprint of the buildings in my region"
Fiche n°06 issue du recueil « Demain mon territoire », copublié par l’ADEME et les EcoMaires à destination des élus locaux pour les aider à intégrer la dimension environnementale dans leur programme au travers de vingt fiches thématiques donnant des pistes d’action et des exemples de solutions mises en œuvre.
 
Pour répondre à la loi de transition énergétique de 2015, les municipalités ont une obligation d’exemplarité énergétique sur leurs bâtiments publics. Certaines agglomérations vont encore plus loin. La métropole de Bretagne a voulu élargir son champ d’action au-delà de la sphère publique pour...
Fact sheet No.06 from the collection "Demain mon territoire", co-published by ADEME and the EcoMayors, is intended for local elected officials to help them integrate the environmental dimension into their programmes through twenty thematic fact sheets giving avenues for action and examples of solutions implemented.
 
In response to the Energy Transition Act of 2015, municipalities have an obligation to set an energy example in their public buildings. Some agglomerations go even further. The Brittany metropolis wanted to broaden its field of action beyond the public sphere to include the private housing stock in this exemplary approach.
 
To do this, it has created a public energy renovation service, Rénov' Habitat Bretagne, which assists private individuals throughout their energy renovation projects. The "Réseau'Habit Bretagne" platform provides advice and assistance in designing the project. It also allows the individual to be connected to a local network of professionals.
 
Financial assistance for implementing such projects is also granted to individuals, including offers for co-owners and modest households.
Mobilised to achieve energy exemplarity, public players, professionals and private individuals can therefore act together to reduce the carbon footprint and electricity bills while generating economic activity.

Fact sheet No.05 from the collection "Demain mon territoire", co-published by ADEME and the EcoMayors, intended for local elected officials to help them integrate the environmental dimension into their programmes through twenty thematic fact sheets giving avenues for action and examples of solutions implemented.
 
Like all human activities, the activities of a municipality have an impact on the environment. Being pioneers in the implementation of eco-responsible measures is the best way for municipalities to encourage the inhabitants of their regions to commit themselves in turn to sustainable management of their activities. To reduce its environmental footprint, Normandy has opted for renewable energies. Many public establishments have been equipped with photovoltaic panels to ensure their complete electrical autonomy.
 
In Le Chefresne, the church has been covered with photovoltaic tiles, thanks to which the bells ring. For its part, the Valdallière municipality is supporting the wood-energy sector by favouring wood heating for municipal buildings and is committed to reducing air pollution by investing in electric public transport.
 
Finally, a regional biomass scheme (RBS) has been adopted to develop biomass from agricultural activities and the food industry, which is highly developed in the region. In total, Normandy's energy bill has been halved. Gaining experience, these municipalities are also gaining in coherence and legitimacy to encourage individuals to take their own actions in favour of the environment.
In one click, discover the energy balance of your region!
Cela ne fait plus débat. Pour répondre à l’enjeu du réchauffement climatique, nous devons décarboner nos villes, nos quartiers, nos projets, notre mobilité.C’est ainsi que nous réduirons nos émissions de CO2 et préparerons un avenir soutenable.
 
Conscient que cette grille de lecture est parfois difficile à obtenir, EDF a conçu un module en ligne qui permet de générer un premier bilan énergétique d’un territoire et d’identifier son potentiel « bas carbone ».
 
En un clic, les décideurs locaux peuvent découvrir le bilan énergétique de leur territoire, connaître...
It’s no longer a matter of debate. To meet the challenge of global warming, we need to decarbonise our cities, our neighbourhoods, our projects and our mobility, which is how we will reduce our CO2 emissions and prepare for a sustainable future.
 
Aware that this reading grid is sometimes difficult to obtain, EDF has designed an online module that generates an initial energy balance for a region and identifies its "low carbon" potential.
 
In just one click, local decision-makers can find out the energy balance for their area, check out its CO2 emissions - whether they result from mobility or the presence of industries, for example - and also discover the potential for Renewable Energy: depending on the region, the solutions to be considered are not always the same so it’s important to understand and know a region in order to make best use of it.
 
The "online energy balance" is a tool that can improve knowledge and strengthen the expertise of communities. It allows us to observe uses, potentially prioritise projects, optimise them, etc.
 
The energy issue is a lever for "acting locally" and "responding globally" to the challenge of global warming: it must therefore be central to the ambition of elected representatives and the administration within their region.
 
By logging on to https://www.edf.fr/collectivites and using their post code, everyone can now discover the priority action levers to be implemented.
 
This tool is aimed at all local decision-makers, whether they administer a large city, a medium-sized town or a rural town.
International Chapel in Paris: a multimodal logistics hotel
30 territoires engagés dans la démarche EcoCité bénéficient du soutien du Programme d’Investissements d’Avenir Ville de Demain géré par la Banque des Territoires pour le compte de l’Etat.
 
5 M€ ont été investis dans le cadre de ce programme au service d’un hôtel logistique multimodal à Paris.
 
Conçu afin d’optimiser l’arrivée des marchandises aux portes de Paris et leur redistribution dans la capitale, l’hôtel logistique est constitué d’un terminal ferroviaire urbain. Les marchandises arrivent par train et sont ensuite déchargées et livrées dans Paris par des véhicules...
30 regions involved in the EcoCité approach receive support from the Avenir Ville de Demain investment programme managed by the Banque des Territoires on behalf of the State.
 
€5 M were invested in this programme for a multimodal logistics hotel in Paris.
 
Designed to optimise the arrival of goods at the gates of Paris and their redistribution in the capital, the logistics hotel consists of an urban rail terminal. Goods arrive by train and are then unloaded and delivered in Paris by low-polluting vehicles.
 
The twice-daily link from upstream platforms should help avoid the movement of 80 000 heavy goods vehicles per year on the Ile-de-France road network.
 
The 45 000 m2 intramuros site also devotes 12 000 m2 to tertiary areas and hosts a business incubator dedicated to sustainable logistics and mobility, higher education institutions and training centres. 10 000 m² of roof space are also devoted to urban agriculture.
Living regions: 9 keys to the ecological emergency
Face aux enjeux du dérèglement climatique, l’échelle locale apparaît comme l’échelle idéale pour innover, expérimenter et mettre en œuvre de nouvelles manières de vivre.
 
Les élus locaux ont ainsi un rôle essentiel à jouer dans la mise en œuvre de mesures à la hauteur pour protéger les milieux naturels, la biodiversité, et les populations humaines qui en dépendent.
 
Avec ce guide, le WWF-France s’engage dans l’accompagnement des transitions locales, en proposant un programme pour des territoires « vivants et désirables ».
 
Constitué de 9 clés...
Faced with the challenges of climate change, the local scale appears to be the ideal level for innovating, experimenting and implementing new ways of living.
 
Local elected officials thus have an essential role to play in implementing appropriate measures to protect natural environments, biodiversity and the human populations that depend on them.
 
With this guide, WWF-France is committed to supporting local transitions by proposing a programme for "living and desirable" regions.
 
Consisting of 9 keys, it establishes recommendations associated with action levers (strategic planning, regulation, public procurement or financial and technical support); to enable local authorities to reinvent towns and regions around vital local functions: live, eat, move, entertain, inform, produce and consume.
 
SUEZ supports local authorities to improve air quality
Chaque année, la pollution atmosphérique coûte 100 milliards d’euros à l’échelle de la France. Les enjeux liés à l’air sont multiples et SUEZ apporte des solutions adaptées pour :
  • Limiter les nuisances olfactives et contribuer au confort des riverains et à l’attractivité des territoires ;
  • Lutter contre la pollution atmosphérique et préserver la santé publique ;
  • Limiter les émissions de gaz à effet de serre et s’engager contre le réchauffement climatique.
Pour faire face à ce défi, le Groupe a décidé d’investir dans la conception, le développement et l’...
Every year, air pollution costs 100 billion euros in France. There are many issues related to air and SUEZ provides adapted solutions to:
  • Limit odour nuisance and contribute to the comfort of local residents and the attractiveness of the area;
  • Tackle air pollution and protect public health;
  • Limit greenhouse gas emissions and combat global warming.
To meet this challenge, the Group has decided to invest in the design, development and operation of innovative air treatment solutions, in France and internationally, such as:
  • The installation of micro-sensors in Santiago de Chile in the heart of the famous "Paseo Bandera" pedestrian street to monitor and analyse air quality (PM 2.5, NOx, CO2, VOC, etc) and monitor public policies in this area;
  • The "IP'Air" experiment, in collaboration with the RATP in Paris, to capture fine particles (PM10 and PM2.5) using a positive ionisation system in underground railway enclosures;
  • The installation of carbon sinks in partnership with Fermentalg, in urban and industrial environments, to transform air pollution into green energy thanks to the power of microalgae combined with the principle of photosynthesis.
Quitri: Citeo's digital platform for sorting everywhere, all the time
Pouvoir trier partout et tout le temps : c’est l’objectif de Quitri, la plateforme digitale de Citeo. Après une expérimentation menée en région Provence-Alpes-Côte d’Azur, puis son lancement au niveau national pour les organisateurs d'événements en novembre 2019, Quitri s'étend désormais aux gestionnaires d'établissements et lieux « hors-foyer »: gares, bureaux, parcs, musées, écoles, camping, cinéma, etc.
 
En effet, plus de 300 000 tonnes d’emballages sont jetées chaque année dans des lieux de consommation « nomade ». Particulièrement consommées dans les établissements recevant du public, les...
Being able to sort everywhere and all the time: that’s the goal of Quitri, Citeo's new digital platform. After an experiment carried out in the Provence-Alpes-Côte d'Azur region, it is now open to all event organisers in France to help them set up collection and sorting free of charge.
 
More than 300 000 tonnes of packaging are thrown away each year in so-called "nomadic" consumption areas, i.e. outside the home: stations, offices, parks, concert halls, camp sites etc. Plastic bottles, cans and trays, which are particularly used during festivals and events indoors or out, are not at all or only lightly sorted due to the lack of on-site facilities, even though they are perfectly recyclable.
 
The Quitri platform makes it possible to collect more packaging for recycling by ensuring the continuity of the sorting process outside the home.
 
The Quitri approach is based on 3 levers:
 
• Simplify: in just one click, Quitri connects site organisers and managers with collection service providers (private or public) in their region who have been previously referenced on the platform.
 
• Sign up: by registering on Quitri, organisers and managers sign a charter of commitments and have free access to communication tools and turnkey support to communicate with the public.
 
• Be rewarded: organisers using a private operator receive 30 euros per tonne recycled traced.
Cities and mobilities - Reinventing proximity
