The report "Barriers and Solutions for Sustainable Household Waste Management in Lagos, Nigeria" examines the challenges of waste management in Lagos, a major urban area in Nigeria with high waste generation. Context: Lagos generates over 13,500 metric tons of waste daily, contributing to environmental issues like plastic pollution, with Nigeria ranking ninth globally for plastic waste output.

Key findings include:

• Poorer households face stronger barriers, such as limited access to waste collection services, lower satisfaction with services, and inadequate knowledge on recycling.
• Primary behavioral barriers are low awareness of waste impacts, convenience preference for plastics, lack of experience in sorting and recycling, forgetfulness, mental dissociation between consumption and waste, low personal responsibility, and habituation to unsustainable practices like burning and littering.
• These barriers stem from psychological, cognitive, and social factors, making behavioral interventions essential alongside infrastructure improvements.

Proposed solutions, based on behavioral science, include:

• Mass awareness campaigns using positive framing and timely messaging to build knowledge and engagement.
• Improving accessibility by providing recycling bins, water stations, and reducing hassles for sustainable choices.
• Altering choice architecture, such as promoting fabric bags as defaults, to shift consumption habits.
• Creating role models and social norms through community influencers, gamification, and rewards systems.
• Using reminders and nudges, like app-based alerts and utility bill notifications, to combat forgetfulness.
• Leveraging empathy and reciprocity, such as fostering relationships between waste pickers and households, to promote community involvement.

Methodology: A mixed-methods approach, including surveys, focus groups, and interviews with 1,100 households across various income levels in Lagos, revealed these insights. The study aimed to understand waste management behaviors and adapt interventions accordingly.

Overall, sustainable waste management in Lagos requires addressing both structural gaps and human behavior, with evidence-based solutions promising significant improvements in waste reduction and proper disposal.
