In the present study, using the referendum contingent valuation method (RCVM), an economic valuation was carried out to implement a recycling system. For this, the population of the municipality of Texcoco was taken as a case study, to which a simple random sampling method, at the level of household, was applied with a confidence level of 95 %, resulting in a total sample of 402 households. Results show that more than 90 % of heads of households are aware of the garbage problem. However, 70 % of respondents know very little about recycling and almost 100 % of them think it is necessary to set up a recycling system. Moreover, by applying the RECVM, and by adjusting a binary LOGIT model, a weekly willingness to pay (WTP) per house hold equal to $27.18 was estimated. As a result, total benefits of $1,295,915 were calculated per week. The model coefficients were estimated using maximum likelihood.
