COMPOSTABLE ALTAR

[BIOART > COMPOSTABLE ALTAR]2026Lessac, France



PHASE 04 / DOMAINE DE BOISBUCHET



‘Compostable Altar’ is an ongoing artistic research project situated at the intersection of art, biodesign and ecology. Through the development of compostable biomaterials made from locally sourced organic waste, the project explores how artistic practice can shift from producing objects to cultivating ecological processes.

The central idea behind the project is to honour the sacredness of the earth, not as a metaphor, but as an ethical stance. If the ground is a living body, what does it mean to design for it rather than design on it?

Rather than viewing decomposition as the end of an object’s life, Compostable Altar sees it as a form of regeneration. Each altar is conceived as a temporary offering: an architecture designed to disappear, returning nutrients, seeds and organic matter to the earth. In doing so, the project challenges prevailing notions of permanence, authorship and control, proposing instead a practice based on reciprocity, transformation and the agency of living matter.

Each iteration becomes a new chapter in the same research. The methodology remains the same, whilst the materials, construction systems and narratives are rewritten by the territory in which it unfolds.

During and through the residency at the Domaine de Boisbuchet, this site-specific installation takes the form of a circular totem constructed from compostable bricks moulded in reusable moulds. Drawing inspiration from the architectural culture that defines Boisbuchet, the brick [one of the oldest symbols of permanence] is reimagined as a temporary building unit.

Its overlapping layers form a material cartography of the Domaine. Each stratum corresponds to a different biomaterial recipe and morphology, highlighting the diversity of locally sourced organic waste and the material research behind it. Installed outdoors, the totem will remain in situ until it gradually decomposes, allowing the weather, microorganisms and the passage of time to complete the work.

04.1 / EXHIBITION



The exhibition, presented at the Japanese Guesthouse [which is part of the Domaine de Boisbuchet Architectural Park] reveals the process behind ‘Compostable Altar’ highlighting the methodology, experimentation, and interdisciplinary research that shape each iteration of this environment-sensitive project.

Material Cartography: Before becoming architecture, every brick begins as a recipe.

This archive brings together the material research behind the project: local organic waste, natural binders, reusable moulds and experimental samples. Each recipe contributes to a replicable methodology shaped by the unique resources of each territory and its identity.

Fabrication System: The bricks were produced using a set of modular, reusable moulds specifically designed for this project and manufactured through 3D printing. Each mould corresponds to a distinct biomaterial recipe, giving every brick its own geometry, colour and texture.

Together, they form a material taxonomy that makes the research visible through construction.

Soil Monitoring: This experiment investigates how compostable biomaterials interact with the soil during decomposition.

Over four weeks, three soil conditions were monitored using environmental sensors: untreated soil, coffee-based biomaterial, and wood-based biomaterial. Preliminary results indicate that the wood-based formulation enhances nutrient availability and biological activity, suggesting that compostable materials can actively contribute to soil regeneration.

The Totem at Domaine de Boisbuchet: Historically, totems have symbolised the relationship between communities and the natural world. Reinterpreted through bioart, this totem built from 96 compostable bricks cast from seven distinct biomaterial recipes becomes a contemporary expression of that connection, a living structure that celebrates interdependence.

PHASE 03 / HUNGRY ECOCITIES



‘Compostable Altar’ is a biodesign experiment that brings together art, science, and regenerative agriculture. Developed in collaboration with Le Terre di Zoé, an agroecological farm in Calabria, southern Italy, the project explores circular strategies for transforming agricultural by-products into living installations that decompose and return nutrients to the soil.

The altar functions as both a sculpture and an ecological prototype: a large-scale, biodegradable structure 3D-printed from biomaterials developed from local and seasonal organic waste. During the research process, ecological monitoring using sensors and control of microclimatic conditions allowed data to be collected on the interaction of the soil with the decomposition of biomaterials [including temperature, pH, humidity, electrical conductivity, and nutrient dynamics]. This system generated a feedback loop between decomposition and regeneration.

Through a data-driven parametric design process and AI predictive models, the project visualizes the metabolic dialogue between human creation and natural transformation. ‘Compostable Altar’ proposes a new type of ritual: one that celebrates impermanence, reciprocity, and the intelligence of living systems.

As a replicable, open-source methodology, it contributes to rethinking production, waste, and material culture within the agri-food system, offering an alternative vision in which design becomes an act of care and regeneration.

This project is developed by Betiana Pavón in collaboration with the organic farm Le Terre di Zoè as part of the Hungry EcoCities initiative STARTS.eu

03.1 / MATERIALITY



The physical construction the Altar is based on a research-driven approach to material innovation.

It is composed entirely of biomaterials driven from locally sourced organic waste, mainly agricultural by-products such as plant fibers, citrus peels, pulp discarded from regional juice production and pruning waste [wood].

These organic waste are combined with natural blinders such as starches, natural gums and plant-based micronutrients, creating a biodegradable and compostable composite material that interacts dynamically with the environment.

These biocomposites were then translated into geometries through digital manufacturing, considering their characteristics in terms of construction.

The biomaterial itself can harbour and promote seed growth within its 3D-printed structure, functioning as a germination scaffold. Seeds from specific plants were incorporated, selected for their natural nitrogen-fixing properties and their ability to attract pollinating insects.

Beyond its technical exploration, the development of these biomaterials was conceived as a participatory framework. The project also extends towards the farming community: by sharing methods for incorporating local residues in a circular way.

03.2 / RESEARCH



Data & Soil Life: For three months, soil sensors measured temperature, humidity, pH and and nutrients in a pilot experiment exposed to outdoor conditions and automatic irrigation, simulating a small farm environment.

The results revealed how the decomposing biomaterials enrich the soil, increased its  nutrient availability and improved moisture retention.

Here the numbers show that the ‘offering’ was not symbolic but measurable and regenerative.

Predictive Modeling: Based on this data, two predictive models were created to estimate how soil nutrients might change over time as biomaterial decomposes and is absorbed. Together, these tools convert experimental soil data into interactive, data-driven insights into how biomaterials affect soil regeneration.

Here, AI does not seek to control, but to listen, translating the rhythms of the soil into possible futures.

03.3 / PROTOTYPING



To build the Altar, a large-format JetClay 3D printer was constructed, developed under open source principles.

As contributors to the maker community, we transform collective knowledge into tools that we return to our shared technological heritage.

The open nature of the project places it within a framework of replicability and collective learning, where each Altar can be reinterpreted in a dialogue with its specific territory.





[BIOART > COMPOSTABLE ALTAR > PHASE 03 / HUNGRY ECOCITIES]



03.4 / MORPHOLOGY



At this stage of the project, the Altar was conceived as a set of totems that become a tangible cartography of invisible processes.

The first tower integrates seven layers of data from the pilot experiment carried out previously using sensors that measure soil moisture, temperature, pH, electrical conductivity, nitrogen, phosphorus, potassium, and microclimatic conditions. This data was translated into morphologies using parametric design: organic patterns that express the interaction of the biomaterial with the soil.

The second and third towers propose a new type of ornament: not decorative but informative; not imposed but emergent, a witness to the climatic conditions experienced by the specific location.

Together the totems function as an artefacts of ecological translation. By integrating monitoring, bio-fabrication and symbolism, the totems do not merely represent the ecosystem, but dissolve into it, returning the materiality to the cycles of the earth.

03.5 / EXHIBITION



This exhibition took part in Disseny Hub Barcelona



Installation that merges art, science, and regenerative agriculture to transform organic waste into biodegradable, data-driven sculptures that decompose, enrich the soil, and reimagine design as a ritual of care, impermanence, and ecological reciprocity.

In a world dominated by global uniformity, manual creation stands as an act of resistance: a slow and conscious practice that proposes a non-consumerist approach to objects. Ecology, respect for the vernacular, and experimentation with new materials and narratives converge in this manual creation.

As partners of A-FAD, we are confronted with the execution of a piece, its process, and its very conception. This exhibition explores precisely that intersection where the philosophies of craftsmanship and beauty meet the concept of ‘material agency’.

‘La Materia Construida’ invites artists and artisans to reimagine their interaction with materials. Not as passive elements to be shaped, but as vibrant entities with which to collaborate. This approach encourages a deeper engagement, challenging us to listen and converse with the very substances we craft.

The result is work that emerges from a deep collaboration with matter, revealing its vitality and capacity for action. Thus, the exhibition builds a bridge between ecological approaches and material philosophy in the context of a sustainable and shared future.

PHASE 02 / CYENS



The purpose of this project is to act as a catalytic microcosm, creating a symbolic and physical bridge between humanity, technology and nature. Inspired by ancestral rituals, it proposes the creation of a sculptural piece that is not only an artistic expression, but also a symbolic gesture towards the regeneration of the earth in a post-organic world.

The development of this research and innovation project began experimentally, formulating biomaterial recipes capable of being mechanically extruded through LDM [Liquid Deposit Modeling technology] from locally abundant food and organic waste. The goal is to address current waste management challenges with circular and sustainable solutions through artistic practice.

During the residency, experimentation was key, focusing on exploring the structural potential and compostability of the biomaterials. Material composition and decomposition timelines emerged as primary research areas, with decomposition periods constantly under analysis and documentation. This decomposition symbolizes a harmonious cycle in which artistic creation directly contributes to new life. 

By blending sustainable materials and artistic expression, the project underscores the potential for symbiosis between art, ecology, and regenerative processes, inspiring a deeper reflection on human impact on the environment.
