| Summary: | 博士 === 國立成功大學 === 資源工程學系碩博士班 === 97 === The technologies and scale of waste lubricant recycling have been considerably developed to a certain level in Taiwan. However, the technical scale fails to be brought into sufficiently and well-organized system resulting in poor recycling rate. Currently, an illegal recycling system which balances the production and disposal of waste lubricant is under operation but it is yet to be examined to see if the recycling processes meet today’s standards in connection with environmental protection, economy and redundant pollution.
This paper indicates that in the Waste lubricant recycling system, government policy is the main key among stakeholders, also aiming at the fishing vessels at the fishing ports in southern part of Taiwan. With in-depth interviews and system dynamic model, the supervision over and recycling mechanism for waste lubricant from the fishing boats at the ports in Taiwan are thus discussed and studied. It is expected that the findings of this paper help construct an effective waste lubricant recycling management system as reference for related organizations and units.
The findings of this paper including: (1) The recycling mechanisms for waste lubricant from the fishing vesse;s are interacted with cause-and-effect relationships. A negative correlation is presented between the return on investmental and environmental costs. (2) The hazardous materials caused to the environment can be reduced if the members outside legal recycling system could be incorporated in it. (3) The limitations still exist even the government has been double focusing on both formulating a subsidy and enhancing the education of environmental protection and recycling lubricant for the fishermen. (4) The balance between economy and environmental protection can be gradually reached under dynamic changes through policy-making. (5) Within the waste lubricant recycling system, the utilities and transportation facilities for waste lubricant and recycled oil should be strengthened so as to speed up oil delivery and reduce unbalanced demand and supply due to geographical factors. (6) From system dynamic model, government should promote the fact that products made by refined or regenerated from waste lubricant are better than originally lubricant because of de-sulfur process. Within such promotion, demand may be increased in order to improve the competitiveness of waste lubricant in the market and to reduce the overall supply chain costs. (7) According to the analysis of the system dynamic model, it is found that the volume of recycled waste lubricant will continuously remain at an increasing growth rate every year if the related policy is promoted with greater efforts.
