Engineering Biocomposites: Circularity in Façade Cladding Systems with Complex Geometries
Modern facade design requires materials that balance developability, economy and industrial feasibility. However, conventional materials such as aluminium pose environmental challenges. This research proposes Fibre-Reinforced Biocomposites—Flax-PLA laminate—as a solution. Once proven ‘developable ‘, this biodegradable, renewable material with competent mechanical properties could revolutionise cladding systems.
By validating the viability of biocomposites, we alter the paradigm of the facade industry, shifting towards sustainable, low-tech and scalable solutions. Testing demonstrated Flax-PLA laminate’s ability to retain strength and quality, suggesting significant carbon savings and lower global warming potential than aluminium. This research promotes a model that prioritises product integrity, enabling reuse and reshaping post-first service life. Such development lessens environmental burdens and fosters societal resilience against future ecological uncertainties.
This breakthrough integrates urban and agricultural economies, opening pathways for localisation based on available infrastructure. Demonstrating the feasibility of biocomposites for geometric cladding supports cleaner production and carbon sequestration, propelling sustainable urban development and contributing to a circular built environment.
