Sustainable indoor air purification using treated puffed rice waste: a functional and structural material evaluation

Research output: Contribution to journalArticlepeer-review

Abstract

Introduction: The study addresses IAQ and rice waste management with a bio-based material for CO₂ capture. Methods: Rice was thermally puffed and treated with NaOH. Characterization and performance evaluation were conducted. Results: Achieved 38% CO₂ removal at 2 M NaOH treatment, with enhanced porosity confirmed. Discussion: The material provides a sustainable IAQ solution, suitable for architectural integration.
