Abstract: The life cycle assessment and the ReCiPe method were used to evaluate the environmental impact of the Municipal Solid Waste Management (MSWM) in a Mexican city. As Functional Unit (FU) was used 1 ton of waste. Two scenarios were considered: MSWM with conventional landfill (A) and MSWM that use the landfill gas to generate electricity (EG). The hotspot of the A scenario was the landfill, the severest midpoint indicator was the climate change, quantified at 2914 kg of CO2 eq/FU, which contributes significantly to the endpoint indicator damage to human health, evaluated at 90 Pt/FU in terms of single score. For the EG scenario the results showed that the environmental impact was reduced to 298 kg of CO2 eq/FU and 5 Pt/FU for climate change and damage to human health, respectively. In the overall analysis, the environmental damage for A and EG scenarios was estimated at 90.5 and -20.8 Pt/FU, respectively. This work shows that the EG scenario represents an alternative potential for environmental improvement. However, due to the emissions from landfill will continue for 50 years, causing damage to human health and ecosystems is considered a persistent environmental passive

La etapa cr´ıtica del escenario A es el relleno sanitario, su indicador de punto medio mas severo es el cambio climatico, estimado en 2914 kg de CO ´ 2 eq/UF, que contribuye significativamente al indicador de punto final dano a la salud humana, evaluado en 90 Pt ˜ /UF en terminos del single score. En el escenario GE el impacto ambiental se reduce hasta 298 kg de CO2 eq/UF y 5 Pt/UF para el cambio climatico y el da no a la salud humana, respectivamente. De manera total, el dano ambiental para los escenarios A y GE fue estimado en 90.5 y -20.8 Pt/UF. El escenario EG muestra una alternativa potencial de mejora ambiental, no obstante, las emisiones del relleno continuan durante 50 a ´ nos, causando da nos a la salud humana y a los ecosistemas, considerado por esto un pasivo ambiental persistente
