Study on the Solid Waste Properties and Disposal Methods of Island at Home and Abroad

Abstract

In order to promote the rational development and utilization of the islands in China, the characteristics and disposal methods of the solid waste of the islands at home and abroad were summarized in this paper, and several proposals for island solid waste management and Chinese island development were mainly discussed in view of the problems. The results show that the island solid waste per capita output was generally higher than the mainland area, and the total output varied with seasons. The organic content of solid waste was higher in the island that mainly developed planting and breeding, while the paper and plastics content of solid waste was higher in the island that mainly developed tourism. Due to the remote location, the cost of solid waste collection and transportation was high. It was difficulty to select landfill site because of the lack of land, and the incineration and compost on islands were not mature enough, and the technique of waste-to-biofuels was still under exploration. Base on the characteristics of island solid waste and the difficulties in the disposal process, solid waste reduction and treatment process improvement on islands were recommended. Three ways of island solid waste disposal were summarized so as to provide reference for sustainable development of Chinese islands.
