Banana Matters transforms discarded banana pseudostem biomass into carbon-sequestering architectural panels through material research, bio-based binders, and digital fabrication. The project addresses the untapped potential of nearly 525 million tonnes of annual banana waste by developing lightweight, low-carbon composites with acoustic and structural applications. Through iterative material experimentation, heat-press manufacturing, and mechanical and physical testing, optimized panel formulations were identified. The outcome demonstrates how agricultural waste can be translated into scalable, circular building materials, reducing embodied carbon while creating new opportunities for architecture and sustainable construction.
Construction materials contribute significantly to embodied carbon. Agricultural residues are abundant yet underutilized. Banana cultivation alone generates enormous quantities of waste each year, with most pseudostems discarded after a single harvest.

Although banana fibres have been explored for industrial products, their architectural potential remains largely unexplored. Our research bridges this gap by translating agricultural waste into digitally fabricated building materials.

Final Vision
Towards Regenerative Interiors:Banana Matters demonstrates how agricultural waste can evolve into high-performance architectural systems that combine material innovation, computational fabrication, and circular design. Rather than replacing conventional panels alone, it proposes a new generation of regenerative interior surfaces that store carbon, support disassembly, and reconnect architecture with biological cycles.
