Project description by jury
The project proposes a large urban infrastructure intervention that aims to turn an environmental criticality into a resource for the city of Bordeaux. To overcome the problem of urban waste, a recycling park is created around the Vallée de Jalles, a vast natural area located northwest of the metropolis, on the left side of the Garonne River. Taking advantage of the natural resources of the area, the project moves beyond finding a technical answer to waste management – and proposes a landscape design that reconfigures the territory and integrates low-tech and high-tech facilities, thereby giving birth to a visionary, attractive city of the future.
A wetland system is restored to offer new agricultural opportunities and plots of land are converted into recreational areas, while building units, designed as an aggregation of permeable multi-functional volumes, populate the park. Besides high-tech structures destined for waste treatment and renewable energy production, the project covers a wide functional program ranging from housing to office and commercial areas. Iconic vertical structures acting as “information points” that punctuate the landscape showcase ecological best practices for vertical farming and biodiversity protection.
The Holcim Awards jury Europe was impressed by the multi-faceted approach of the design, going from territorial to infrastructural and architectural scales as an independent system. In particular, the jury commended the project’s use of the natural landscape and its dynamic shifts as well as the restoration of the ancient hydrology to reveal the circular process. Lightweight structures are deployed to favor good environmental practices and the inclusion of the community. Overall, the playful and poetic character of this project was highly commended.See more
As a Main category prize winner in the regional Holcim Awards 2020, Resource Circulation in France automatically qualified as a finalist in the Global Holcim Awards 2021.
France is committed to ambitious environmental goals. Within that scenario, this project aims to turn urban waste into a valuable resource for the city of Bordeaux. A recycling park will be created in a vast natural area to the northwest of the city. The proposed development incorporates not only the technical infrastructure for waste management but also landscape rehabilitation and design. “The project seeks to bridge certain disconnects between the local and the global, between high-tech and low-tech,” explains author Chamss Oulkadi of BOM architecture, Paris, France, “especially in those very specific spaces between the historic city center and the suburban, more-natural surroundings.” The jury was impressed by the multifaceted approach of the design, spanning the regional, infrastructural, and architectural scales as an independent system.Read more »
Pooling and fostering solidarity everywhere
Global warming and the drop in the Garonne's flow make water all the more precious. At the opposite, through its natural resources, water is omnipresent in the humid area of la Jallère. By revealing the topography, and restoring marshlands, the imagery of the recycling park could be created. On a large scale and right at the core of working units, vapor sensor clouds and natural pools regulate microclimates through the “Geogrid” Each person can get involved. A set of measures such as geogrid and I Points develop a landscape of visible energy sources across the area. This is achieved by emphasizing the nature of the site as a positive feature, creating fertile soil and a shifting landscape. In that case, nature is neither tamed nor domesticated.
Toward a micro-management of waste
Regulated by the geogrid, the city of the future could solve the contradictions in our society, growth and contraction, local and global, low- and high-tech. However, beyond the idea of a circular economy, pooling, which is fostered at all levels, is a precious means of moving forward from classic notion of waste management and the commodification of goods and resources. Supported by the digital technology, our principle calls on civil governance that steps up cooperation and solidarity. The project strives to change preconceived ideas by offering a type of autonomy to blocks, which, far from being insular, is considered empowering and inclusive. Thus, we worked to ensure smooth transition toward a micro-management of waste rather than macro-management.
A “geogrid” system punctuated with “Information Point”
The geogrid draws on a territory’s history, and enrich the idea of the smart grid, to design for Bordeaux a future that is breathable. Subject of particular attention, the grid is punctuated with “Information Point”, somewhat poetic vertical structures akin to stilts. Interconnected I-Point contribute to a collective effort, ensuring an overall balance. Disconnected, it gains temporary autonomy since they are equipped to perform essential functions ranging from renewable energy production to thermal regulation. Furthermore, it is aims to make the consumption of local resources visible. Enough to make anyone (and everyone) take responsibility. Structured in rational way, they punctuate the vast scope of this coherent energy network, able, by 2050, to make this territory self-sufficient.See more
The zero-carbon objective could be envisaged in simultaneous micro-macro-scope. Building, parcel, specific use, district, territory – we push back classic boundaries to bring about the re-emergence of a more ancient hydraulic geography, one where water flows thought the JALLES (Gascon word for river).
Once they have been revealed, these resources are revered and protected. The water cycle, the presence of which is felt even more strongly, serves every field of activity, from the process of making use of waste the transportation of goods. In short, we are talking the advent of “L’eau-gistics” or maybe even “lowgistics”.
A poetic design for a visionary city development in Bordeaux where the natural resources trigger new sustainable dynamics.

Our website search engine covers the web pages including project descriptions and expert profiles, PDFs, images and videos on the Holcim Foundation website. To improve your search results, here are some tips:
Our search defaults to term-pairing AND. If you search sustainable construction - then the search engine will look for any items containing sustainable AND construction
photovoltaic OR solar
Looks for either word
(clay OR mud) AND (school OR university)
Combine alternative terms for more specific searching
Excludes a term from results, automatically ANDs other terms listed
Use quotation marks to search for a specific phrase or combination
Asterisk (*) matches any word or phrase - so archit* will find architect, architecture, architectural as well as architrave
