Abstract

Embunara is a sustainable, solar-powered aromatic diffuser crafted from raw bisque-fired stoneware ceramic. Inspired by traditional reed diffusers and guided by eco-conscious design principles, it eliminates the need for sticks, flames, or external heat sources by utilizing the natural porosity of unglazed ceramic for passive scent diffusion. A detachable solar module powers a low-energy fan to enhance aroma dispersion, while also functioning as a portable power bank. Rooted in Malay philosophical beliefs about the human connection to the earth, Embunara integrates cultural narrative, material innovation, and functional simplicity to propose a safer and environmentally responsible alternative to conventional diffusers.
