The Compost Poster is an educational communication tool designed to increase composting participation by explaining the environmental impact of food waste. Created for zero waste managers, schools, workplaces, and community facilities, the poster is placed near kitchens, food preparation areas, and waste stations to provide a timely reminder about why composting matters.

The poster uses behavioral science principles including salience, environmental cueing, and point-of-decision interventions by delivering information exactly where disposal choices are made. Through simple visuals and clear messaging, it explains how food scraps sent to landfill break down without oxygen and generate methane, a potent greenhouse gas, while composting returns nutrients to the soil and reduces emissions.

As part of a broader compost awareness campaign, the poster helps transform waste sorting from a routine task into a meaningful environmental action, increasing understanding, participation, and support for organics diversion programs.
