ABSTRACT=IntroductionThe study addresses IAQ and rice waste management with a bio-based material for CO₂ capture.MethodsRice was thermally puffed and treated with NaOH. Characterization and performance evaluation were conducted.ResultsAchieved 38% CO₂ removal at 2 M NaOH treatment, with enhanced porosity confirmed.DiscussionThe material provides a sustainable IAQ solution, suitable for architectural integration.
