Abstract

A linear fractional programming based solid waste management planning model was proposed and applied to support the planning of urban-rural solid waste management in Xiamen, China. The model could obtain the best system efficiency while solving the tradeoff between economic and environmental objectives. It aimed to effectively address the urban and rural solid waste management planning through minimizing the system cost and optimizing system efficiency in the developed model framework. Through the model, the optimal waste flow for each facility was obtained, and the problem of overburdened landfill in Xiamen’s urban and rural solid waste management system was solved. The solutions for waste allocation and facility capacity expansion were provided for Xiamen’s urban and rural solid waste management. The planning results showed that about 42.44 × 106 tons of waste would be diverted to other facilities from landfills over the planning period of 2018-2032, and the waste diversion rate would reach 97%, which would greatly reduce the burden on landfills. The economic efficiency of waste diversion would be 5.07 × 103 ton per 106 RMB. All the capacities of Xiamen’s urban and rural solid waste management facilities including incinerators, composting plant, and landfills should be expanded because of increasing waste production rate.

Highlights

With the gradual acceleration of the urbanization process and the continuous improvement of people’s living and consumption levels in China, the production of solid waste has increased dramatically in the past two decades [1]
In the development process of urban and rural integration, the scope of city is expanding, many villages and towns are being gradually transformed into new urban areas, and the boundaries between rural and urban areas are becoming blurred
The aim of this study is to develop a coordinative solid waste management planning model based on linear fractional programming and apply it to support the coordinative urban-rural solid waste management planning in Xiamen, China

Summary

Introduction

With the gradual acceleration of the urbanization process and the continuous improvement of people’s living and consumption levels in China, the production of solid waste has increased dramatically in the past two decades [1]. The annual growth rate of solid waste has exceeded 10% in China, and a number of cities and towns are surrounded by more than 70 billion tons of solid waste, covering an area of more than 500 million square meters. In the development process of urban and rural integration, the scope of city is expanding, many villages and towns are being gradually transformed into new urban areas, and the boundaries between rural and urban areas are becoming blurred. The situation of gross urban and rural solid waste growth is grim. The problems of “garbage siege” and “garbage to the countryside” have become serious obstructions for the urban-rustic sustainable development, since this solid waste could potentially result in severity waste of urban and rural
