Despite awareness of sustainability, a gap remains between consumers’ intentions and actual behaviours, that influencing the decision making in using or buying things. This study explores how material properties influence user perceptions and acceptance of sustainable straw alternatives in an urban context. An experimental session was conducted with 60 undergraduate students at UTM Kuala Lumpur. The study tests six types of sustainable straws which are bamboo straw, paper straw, rice straw, sugarcane straw, PLA straw and Coffee Bioplastic straw, using an abductive research approach and analysed using statistical software, SPSS. Findings indicate strong consumer preference for sugarcane and bamboo straws, driven by positive sensory attributes, durability, environmental friendliness, and emotional experience. In contrast, coffee bioplastic straws were the least favoured due to poor tactile experience and unclear sustainability claims. By highlighting the psychological, sensory, and aesthetic dimensions of material acceptance, this research offers actionable insights for designers, product developers, and sustainability advocates to enhance the commercial viability of green products. Ultimately, integrating consumer preferences in early stages of sustainable product development is essential for advancing material innovation and fostering greater public engagement in environmental initiatives.
