Abstract

A sustainable process satisfies the current needs without compromising the ability of future generations to satisfy their own needs; that is, it must have a triple impact (sustainability): social, economic, and environmental. In México, there are several services that the government must provide to society for its proper development, for example, the collection of solid waste. Urban logistics include all the processes and operations that provide a service to the community, such as water, safety, health, waste collection, etc., providing the service with the lowest possible cost (economic, social, and environmental) that contributes to the sustainability of the city. Due to the accelerated growth of the world population, several environmental problems have arisen, among them, the generation of solid waste in important quantities; their proper management is relevant for adequate development of the population. The collection of solid waste in municipal areas aims to grant green spaces and recreation areas for the citizens. Although an outstanding effort has been made by the government to provide an adequate service, there are still gaps in the application of correct tools that guarantee efficiency in operations and continuity in services. This article presents a proposal to improve the planning of the design of territories for the cleaning, weeding, and collection of solid waste in municipal areas, using two MILP (Mixed Integer Linear Programming) models. The main contribution of the adaptation of this model is the application to the weeding and waste collection service municipality of the Monterrey Metropolitan Area, which considers important factors among which are the amount of waste, frequency, and service coverage.

Highlights

In Mexico, the government is responsible for urban solid waste management (USWM) and the cleanup of green and public spaces
In the last few years, the term Urban Logistics have come to play [1], referring to the activities that provide a service to the community, such as water, safety, health and waste collection, and green spaces weeding, at the lowest possible cost in order to contribute to a sustainable city
Once the previous design has been obtained for each supplier, it is necessary to carry out a second grouping because one of the most important factors of cleaning and solid waste collection in parks is the frequency; in this case, it is considered that the cleaning of each of the parks must be held every month, i.e., every 4 weeks

Summary

Introduction

In Mexico, the government is responsible for urban solid waste management (USWM) and the cleanup of green and public spaces. This activity is very important for cities; it has become a difficult task to perform as this service has very limited funds. Taniguchi et al [2], Winkenbach et al [3], Macário et al [4], and Villamizar et al [5] mention that it covers multiple objectives These types of activities have a positive impact on the city’s industrial supply chains. The need to control the damage to the population and the environment transforms waste collection in a public and private matter. This leads to the need for developing solutions, mainly focused on the administration, collection, and disposal of waste
