||Methods used for waste disposal as described in Taiwan’s waste management policies evolve from landfill to incineration supplemented by landfill, incineration combined with landfill, and now technology that is economical or feasible in promoting recycling and reuse, in order to gradually achieve the goals of resource recycling and zero waste. However, the continuous development of industry and business in Taiwan has led to the continuous production of waste. As the volume of current landfills is limited and it is not easy to establish new landfills, facilities are needed for final management of the waste produced by enterprises. In light of this, the Environmental Protection Administration of the Executive Yuan promulgated the Waste Disposal Policy Assessment Notes in April, 2012, in which promotion of the policy on the Removal of Waste to Rehabilitate Landfills was planned. This policy provides county and city governments with a reference as to whether they should proceed with final disposal or temporary storage of waste. Following this policy, this study explored the questions facing the removal of waste to rehabilitate landfills by means of rent (or rehabilitate)-operate-transfer (ROT) and the possible outcomes of this project.|
To discuss the feasibility of the ROT project for the removal of waste to rehabilitate existing public landfills, the scope of this study included the closed public landfills in Tainan City. A piece of land of the Taiwan Sugar Corporation was rented and used as the object of this research on the removal of waste to rehabilitate landfill A. Basic data on the current status of the landfill, its operations and management, the environmentally friendly facilities in its main part and the analysis of historical waste were collected and established. Data on the current statuses of waste management facilities in Tainan City (including those of public landfills currently in operation, landfills and facilities in incineration plants) were also collected to be used as a reference regarding the planning of subsequent operations. Subsequent operations management of the landfill was planned and subsequent optimization measures were then taken to establish basic hypotheses and parameters related to the case study, so as to conduct various feasibility studies on the ROT project for the case.
The findings of these feasibility studies were used to discuss the development projects on the feasibility of private participation in the removal of waste to rehabilitate landfills and the development plans that meet both the public and private interests. A feasibility assessment model for the complimentary measures was planned. Finally, the feasibility analysis on the ROT project, regardless of market, law, engineering technology, finance, land acquisition and environmental impact, concluded that the project is feasible. The significance of management in terms of social and economic benefits, as well as government finance, was also summarized. In addition, this study proposed recommendations for the planning of engineering, operations and ROT projects, which can provide a reference for investors and government agencies regarding the removal of waste to rehabilitate landfills.
