Strategic Planning for Managing Municipal Solid Wastes with Consideration of Multiple Stakeholders

Abstract

Management of municipal solid waste (MSW) involves multiple stakeholders such as government agencies, suppliers, consumers, providers of treatment/recycle services, and transporters. An optimal management strategy should be based on creating synergistic opportunities that benefit the multiple participants. This paper presents a multi-objective optimization approach for the strategic planning of a municipal solid waste management system. The formulation considers the involved tasks such as recycle, reuse, transportation, separation, and distribution. The proposed approach also accounts for the multiple stakeholders with the objective of maximizing the benefit to all the participating stakeholders. The Latin Hypercube sampling technique is adopted to systematically generate weights for the different stakeholders. A case study from Mexico is analyzed where three scenarios are considered. The first one considers that the separation cost is absorbed by each recycling company. The second one assumes that the government is responsible for the separation cost. The third one requires household inhabitants to carry out waste sorting. The optimization approach is used to analyze the results of the various scenarios and to deduce valuable insights on the interaction among the various stakeholders and the building blocks of the supply chain of MSW management systems.

Optimal Policy-Making for Municipal Waste Management Based on Predictive Model Optimization

“…The model of Santibañez-Aguilar et al also considers the safety aspect of waste management. A multi-objective model is proposed by Diaz-Barriga-Fernandez et al [40] for the multi-stakeholder problem. The objective of various functions of the models is the maximization of the total net profit in the MSWS.…”

A critical review: emerging bioeconomy and waste-to-energy technologies for sustainable municipal solid waste management

“…When trying to attain the goals of waste management, what are always required are tailor-made, regionally adopted, and cost-efficient concepts fitting the various levels and dimensions of social needs. More importantly, they are likely going to be backed by the stakeholders and citizens as ways to solve their existing issues [22][23][24]. Since MSW management involves the whole elements of collection, transport, disposal and treatment of waste, along with regulation and monitoring of the waste management process, there are many intertwined factors which influence this complicated process in regard to more sustainable MSW management.…”

Sustainable supply chain network design for the optimal utilization of municipal solid waste

“…A case study in the region of Mexico was used to investigate the tradeoff between the social, economic, and environmental criteria. Through a study conducted by Diaz-Barriga-Fernandez et al 28 , the strategic and operational planning of an MSW management system was presented with the aim of minimizing the costs associated with transportation, separation, and production of the products obtained from the recycled residues, in addition to increasing the profit of all involved stakeholders.…”
