Peelcraft is a home-use mold kit designed for eco-conscious households and educational programs. It solves kitchen waste by upcycling discarded pomelo peels into durable, reusable bowls. The process utilizes the peels' natural antibacterial qualities and shrink-to-harden behavior during simple air-drying or low-temperature baking, eliminating the need for synthetic additives or industrial energy. The resulting bowls are 100% biodegradable and compostable.
