The paper evaluates the efficiency of public spending on solid waste management in the municipalities of the Puno region, Peru-2019. The one-stage input-oriented Data Envelopment Analysis of Constant-Scale Returns (DEA-CRS) and Variable-Scale Returns (DEA-VRS) methodology is used to calculate efficiency scores, with a population of 109 municipalities. The TOBIT regression model is used to evaluate the determinants of efficiency. The results show inefficiency in municipal waste management; on average, the municipalities of the Puno region could collect one ton of solid waste per day with 82% fewer resources, with the most efficient municipalities being Juli, San José, Santa Lucia and Juliaca. The resources from the canon and the decrease in the frequency of solid waste collection are negatively associated with efficiency scores, while municipal planning through the implementation of the solid waste management plan and including a greater number of operational collection trucks positively influenced the efficiency of public spending on municipal waste management.
