The 21-Day Zero-Waste Challenge is a simple, yet powerful tool designed to help participants commit to living without creating waste for 21 consecutive days. The challenge begins with the participant writing down their name, date, and pledge, followed by checking off a circle each day as they progress towards the goal of zero waste. The design incorporates behavioral science principles such as commitment theory, goal setting, and progress tracking, all of which stimulate the dopamine reward system to encourage daily engagement.
