Recycling urine to fertilize the soil

“ Making the most out of urine in agriculture isn't a technological or technical issue, it's a matter of social organization. ”

Since urine is an inexhaustible ecological fertilizer, why not use it instead of chemical fertilizers that are expensive to produce? Designer Louise Raguet suggests bringing back to the fields what has been collected there. Her research with the LEESU laboratory (École des Ponts) has led her to develop a unique project: urine separation in the future Saint-Vincent de Paul district of Paris.

Sound, the Great Forgotten Dimension of Architectural Practice

Carlotta Daro co-led, together with Nicolas Tixier, the Radio Utopia project that animated the French Pavilion at the Venice Biennale in 2023. She is now part of the Gramazio Kohler research group, which focuses on the contribution of digital technologies and new materials to architectural design. There, she leads a research project dedicated to developing virtual reality tools enriched with acoustic simulations, designed to support architects throughout their creative process. This work paves the way for a constructive approach in which sound—too often considered primarily as a nuisance—moves beyond measurement and mitigation to become a perceptual and experiential factor.

Bringing together an architectural project and a collection project 

L’agence PCA-STREAM dirigée par l’architecte Philippe Chiambaretta a signé en 2006 le projet de réhabilitation d’un immeuble tertiaire destiné à accueillir le tout nouveau Centre d’Art Contemporain de Kiyv. Le projet architectural s’est construit en parallèle du positionnement éditorial et de la constitution de la collection, en collaboration étroite avec le mécène du projet Viktor Pinchuk et le curateur Nicolas Bourriaud. Retour sur la genèse de ce projet ambitieux, destiné à ouvrir l’Ukraine sur le Monde.

“ Artificial intelligence is revolutionizing our relation to history, giving us access to previously indecipherable archives. ”

Using AI to tell history

“ Artificial intelligence is revolutionizing our relation to history, giving us access to previously indecipherable archives. ”

Using AI to tell history

On February 10 and 11, France hosted the Summit for Action on Artificial Intelligence, bringing together international companies and heads of state to identify the potential and limits (notably environmental) of this tool. This is an opportunity for us to discuss the subject of generative AI with Raphaël Doan, a specialist in the sciences of Antiquity and author of the uchronia Si Rome n’avait pas chuté (If Rome hadn’t fallen), an essay imagining, with the help of AI, what might have happened if the Industrial Revolution had taken place under the Roman Empire. Through this experiment, fascinating possibilities for historical and archaeological research are outlined, as AI facilitates the processing of archives, the translation of lost languages and the deciphering of burnt texts.

Podcast transcript: urban metabolism, at the heart of the matter

Podcast transcript: urban metabolism, at the heart of the matter

In urban planning and geography, the concept of metabolism is frequently discussed. This organicist metaphor likens a territory to a body, traversed by flows of materials and energy that link it to its environment. From a quantitative perspective, these flows can be measured over time and space to assess what a territory consumes, processes, and produces. However, a qualitative approach is equally crucial, examining the political and social trade-offs that shape urban metabolisms. With this in mind, we spoke with two researchers, Clément Dillenseger and Pierre Desvaux, who have explored the waste sector to analyze the socio-technical infrastructures that underpin metabolism and the imaginaries that shape its perception.

Educating Citizen Architects: for a meaningful architecture

Andrew Freear runs the Rural Studio program at Auburn School of Architecture (USA). He believes that schools of architecture have an ethical responsibility to train citizen architects who are locally committed to concrete projects and experientially connected to contexts and places. To design an inclusive city, the Studio adopts an experimental field approach, combining analysis of the territory’s endemic problems, understanding of residents’ needs and new construction techniques.

Culture as a weapon

In this exclusive interview, Björn Geldhof, director of the PinchuckArtCentre in Kyiv, looks at the evolution of the centre’s cultural programming since the outbreak of war in Ukraine. From an institutional space whose primary role was to open up the country to the world, the centre has evolved into a platform for committed and activist research, carrying the voice of Ukraine throughout Europe. By using art to document the conflict, the PinchukArtCentre uses a factual approach to raise awareness in the spheres of opinion and decision-making, thus affirming its role as the country’s ‘artistic arm’.

The potential of the night

The potential of the night

Once a sanctuary for dreams and imagination, nighttime has now been relegated to the mere role of a utilitarian prelude to daytime. Nocturnal realms possess an alchemical power capable of transfiguring our perceptions. However, when viewed through the lens of urban uses, the night also exacerbates inequalities and raises questions about the possibility of achieving an urban night that is accessible to everyone. Exploring the range of possibilities associated with the night reveals it as a space-time where complex interactions are woven that could be revitalized through a chronotopic and inclusive architecture.

“ My research question was: How do tools for integrating biodiversity into urban and architectural projects contribute to shaping multi-species urban worlds? ”

Translating biodiversity

“ My research question was: How do tools for integrating biodiversity into urban and architectural projects contribute to shaping multi-species urban worlds? ”

Translating biodiversity

In this first episode, Léone revisits the genesis of her research topic and traces the evolution of her methodology. She adopts a “material semiotics” approach, focused on how biodiversity tools translate and make ecological knowledge perceptible. These tools are analyzed as “cosmograms,” according to John Tresch’s concept: objects designed to summarize the order of the world by materially organizing the relationships between humans and non-humans. But an examination of the diversity of these tools quickly reveals the difficulty in producing shared representations of biodiversity. This heterogeneity opens an investigation into the often implicit ways in which these tools shape our thinking and conceptions of the multi-species city.   Working with diversity: Operators sensitive to non-human life in urban and architectural projects In this series of four podcasts, we invite you to delve into the work of Léone, a researcher at the agency, who recently defended her CIFRE PhD thesis in Science and Technology Studies, supervised by Jérôme Denis at the Centre for the Sociology of Innovation (École des Mines, Université PSL). A series presented by Léone-Alix Mazaud and Jasmine Léonardon. Editing: Théa Lingrand.
