Increasing Appropriate Composting in High-Traffic University Settings.

Area of Science:

• Environmental Science
• Behavioral Science
• Waste Management

Background:

• Composting systems are crucial for global sustainability but face contamination challenges.
• Current behavior analytic strategies for waste disposal adherence often require significant resources and oversight.
• Developing effective, low-resource interventions for proper organic recycling is essential for widespread adoption.

Purpose of the Study:

• To investigate a purely antecedent-based intervention to improve organic recycling adherence.
• To assess the efficacy of enhanced compost bins in reducing contamination in a university campus setting.

Main Methods:

• A field study employing a multiple-baseline design across multiple dining sites.
• Implementation of enhanced compost bins featuring specific colors, hinged doors, and site-specific signage detailing compostable and non-compostable materials.

Main Results:

• The enhanced compost bins significantly reduced contamination from inorganic and unsuitable organic refuse.
• The antecedent-based intervention demonstrated effectiveness in nudging proper organic recycling behavior.

Conclusions:

• Enhanced compost bins represent a viable, low-resource strategy for improving composting system efficiency.
• This approach offers practical implications for university implementation and future research in sustainable waste management.
