R-Harn Thai Series

Capturing Local Recipes on Tiles

Made from over 20% food waste collected from restaurants and hotels across Bangkok, each tile in this collection reveals the natural beauty of discarded ingredients in their raw, unaltered form. As part of the Wastematters campaign, we collaborate with F&B partners to separate and collect clean food waste, transforming it into sustainable surfaces that bring waste back to the table — as texture, strength, and innovation.
