This project conducted performance evaluation and provided improvement recommendations to kitchen waste composting plants located in 6 townships in Pingtung County, including Linbian Township, Hengchun Township, Sinpi Township, Liuqiu Township, Kanding Township, and Sandimen Township. With the exception of Sandimen composting plant which the liquid fertilizer process has been suspended and solid fertilizer/manure fermentation equipment had not been installed, all other composting facilities have plenty of reserve capacity. Due to its remote island location, the Liuqui composting plant can only handle kitchen waste; all other composting plants shall be elevated to regional disposal plant status, so that they can handle other townships’ kitchen waste and improve the County’s overall waste recycling rate. Before the submission of mid-term report, this project has provided recommendations for improvement on the composting plants’ hardware infrastructure and operating conditions. The status of improvement has also been followed and found that Sinpi plant has shown the most significant improvement while the Linbian plant is able to maintain excellent operation. The project is providing assistance in planning for the hardware improvement in the Kanding plant, and is asking the contractors to work on the improvement project. The project is also providing assistance to Kanding plant and Liuqui plant in preparing improvement plan for submission to the EPA in applying for financial assistance. The Sandimen plant’s liquid fertilizer process is in operation but the performance is still poor, therefore the project has urged the plant to accelerate its contracting of solid fertilizer processing facility construction to avoid overloading the liquid fertilizer process. The overall performance of the Hengchun plant is good, and once inter-regional cooperation is fully implemented in the future, its processing load can be increased to improve economic efficiency.
On the part of conducting promotional activities, promotional events were held in northern Pingtung, southern Pingtung and coastal townships to promote the benefits of kitchen waste and bulk waste recycling. Face to face discussions were also conducted with captains of the township waste collection teams to understand the difficulties they face in conducting recycling of kitchen waste and bulk waste regarding the administrative, technical and financial aspects. On the administrative aspect, the most difficult tasks are seeking residents’ cooperation in waste sorting and inter-regional cooperation; on the technical aspect, the field operation of kitchen waste composting and treatment of liquid fertilizer is most difficult. The challenging issues on the financial aspect include securing subsidies and cost sharing of garbage transportation. The project has served as a coordinator to provide supporting information and reporting the difficulty to competent authorities to ask for assistance.
On the part of "Planning of promotional strategy to enhance the County’s recycling of kitchen waste," comments on kitchen waste recycling have been collected from the townships and villages to serve as references in developing coping strategy. The following promotional strategy and implementation measures have also been proposed, including: 1. Ask townships to cooperate in implementing administrative measures; 2. Strengthen the statistical data, to avoid omission of kitchen waste already been recycled; 3. Conduct diversified promotions to improve the recycling rate; 4. Enhance waste sorting to improve kitchen waste recycling rate; 5. Diversify reuse methods to increase County’s overall recycled kitchen waste.
On the operational test of anaerobic digestion system, the last project has ended in March 2010, and this project will continue to conduct operational testing for 6 months and will submit the performance testing report. In line with the international trend of promoting renewable energy, the energy recovery through anaerobic digestion of organic waste will be Pingtung’s leading innovative approach of the nation, and will serve as a good foundation for Pingtung’s promotion of green energy in the future.
