Various nations in the world have developed technologies and strategies for appropriate waste disposal, and to abate waste generation and greenhouse gasses. Alternatives like recovering materials can help, but they require reliable information to improve planning and management. This study quantifies the Carbon dioxide (CO<inf>2</inf>) emissions produced by the lack of valorisation of materials in a Mexican city. Two waste characterisations in a lower-class neighbourhood were carried out. For the CO<inf>2</inf> emission estimation, two scenarios were considered. DEFRA emission factors for waste treatment processes were used. Waste generation was 0.64 kg/capita/day in the first study, and 0.50 kg/capita/day in the second. The CO<inf>2</inf>eq emissions of collected waste in the neighbourhood were estimated at 1824 kg for 2013 (0.20 kg/capita/day) and 1636 kg for 2015 (0.19 kg/capita/day). The behaviour of solid waste management in the city can be explained by the “prisoner’s dilemma” model, studied in game theory, which is ideally suited to analysing situations affected by multiple agents, but requires an accurate understanding of solid waste actors and social implications.
