Abstract

A comprehensive study of the generation and characterization of municipal solid waste is essential to the longterm efficient and economical planning for solid waste management. The aim of this study was to quantify and analyze the solid waste generated in the city of Ensenada, Mexico, and to use this data in a project that will generate energy through methane gas production. Ensenada’s per capita waste generation is approximately 0.87 ± 0.07 kg per person per day within a 98% confidence interval. Ensenada’s solid waste composition consists of food scraps at 34.28%, paper and cardboard 22.49%, plastic 12.53%, disposable diapers 7.14%, and textiles 6.58%. Of the total waste generated, 86.36% has potential for reuse, whereas 13.65% has no further identifiable use and must be landfilled. Of the usable percentage, 48.34% can be recycled and 51.66% can be used to generate energy, obtaining financial and environmental benefits.

Keywords: Municipal solid waste, waste composition, recovery.
