Perception-based design: An approach for engineering sustainable biobased materials

Biobased composites, which are sustainable materials ideally poised to replace fossil-based raw materials, paradoxically are struggling to gain market acceptance. This underperformance is attributed to poor demand and acceptance of biobased composites, driven by technical and perceptual challenges. However, most research on biobased composites focuses on addressing technical challenges and fails to incorporate perceptual qualities into the material development process. By understanding the role of material characteristics (colour, patterns, texture, roughness) in shaping these qualities, we propose that novel biobased composites could be developed to meet specific consumer product needs. A prediction model for generating the desired material perception could help develop novel, sustainable materials that are perceptually appealing to consumers. This paper proposes a modified material design process based on consumer perception. This new process can help material engineers and product designers create new biobased materials that align with the emotional demands of the product segment and user experience.
