THE POTENTIAL OF BIOBASED MATERIALS IN PREFABRICATION A house in Esmoriz built with rice-husk composite panels | IL POTENZIALE DEI MATERIALI BIOBASED NELLA PREFABBRICAZIONE Una casa a Esmoriz costruita con pannelli compositi di lolla di riso

This article explores the integration of biobased materials, specifically rice husks, in the prefabrication of sustainable architectural systems, focusing on a single-family house in Esmoriz, Portugal, assembled on site in 3 days. Rice husks, as a byproduct of agro-industrial waste, have significant potential to improve thermal insulation while preventing CO2 emissions, aligning with the ecological transition in Mediterranean construction. The study emphasises the innovative use of ricehusk concrete composite, showcasing its application in prefabricated modules designed under the Design for Disassembly (DfD) paradigm. By highlighting the architectural and environmental benefits of rice husks, including their role in improving the properties of concrete, this research advocates for a broader acceptance of biobased materials. This approach combines material performance with aesthetic qualities, adaptable spatial solutions, construction site logistics, and the client's willingness to accept the risks associated with using non-standard materials.
