Urban solid waste generation and disposal in Mexico: a case study.
The adequate management of municipal solid waste in developing countries is difficult because of the scarcity of studies about their composition. This paper analyses the composition of urban solid waste (USW) in the city of Morelia, Michoacán, Mexico. Residential and non-residential waste sources were sampled, and a structured interview was made to evaluate the socioeconomic characteristics of the studied area. Also, to determine the seasonal patterns of solid waste generation and the efficiency level of the collection service, quantification of solid waste deposited in the dumping ground was measured. Our results show that the recorded amount of SW deposited in the municipal dumping-ground is less than the estimated amount of SW generated; for this reason, the former amount is not recommended as an unbiased indicator for planning public waste collection services. It is essential that dumping-grounds are permanently monitored and that the incoming waste be weighed in order to have a more efficient record of USW deposited in the dumping-ground per day; these data are fundamental for developing adequate managing strategies.
