This research highlights its potential as a sustainable alternative to synthetic inks. The value of agricultural waste in promoting green chemistry and sustainable practices. It provides a practical example for environmental education, encouraging innovation in biodegradable materials and raising awareness about eco-friendly alternatives in the art and packaging industries. This study aims to develop an eco-friendly natural ink using natural ink from dragon fruit peel is an eco-friendly alternative, derived from the fruit’s vibrant pigments, specifically betacyanin. The main pigment, betacyanin, is extracted from dragon fruit peel and combined with activated charcoal to enhance stability and formulated into ink, offering a biodegradable, non-toxic option. Experimental procedures included ink formulation and user trials in whiteboard applications. The resulting ink exhibits good adhesion properties on whiteboard surfaces. User testing showed satisfactory performance in artistic and packaging uses. However, the main challenge is stabilizing the natural pigments to ensure colour durability and prevent fading.
