Rahman's work explores the intricate interplay between chemistry, economics, and environmental sustainability through the lens of speculative design. Drawing inspiration from Bruneian cultural values of balance and harmony, Rahman envisions future scenarios where closed-loop systems and resource optimization are not simply ideals, but essential components of human survival. Their design fictions offer satirical yet scientifically grounded commentaries on contemporary consumption patterns, prompting audiences to reconsider the long-term consequences of current economic models. Through meticulous research and intricate system modeling, Rahman develops speculative design prototypes that meticulously detail potential pathways toward sustainable futures. These designs are not presented as definitive solutions but rather as catalysts for critical thought and discussion, inviting viewers to engage with the complex ethical and societal implications of technological advancements and environmental change.
