In order to resolve the lack of land space of landfill and illegal disposals, the Environmental Protection Administration (EPA) starts to establish the policy of regulating constructed reclamation ground and the associated environmental impact evaluations. For helping EPA on establishing the policy and the standards of construction materials used for the reclamation ground and the related analytical methods, it is necessary to understand the domestic and international leaching tests and total mass methods, make linkage between the administrative policy and analytical methods of the waste materials, and make the project serve as a good reference on the way Taiwan promotes the policy of waste materials resourcing. This project collects many leaching and total mass analysis methods, screens and introduces suitable methods for Taiwan, and drafts the analytical methods of the leaching test for the materials used for reclamation ground.
This project studied the leaching method and analytical method for total mass from European Union, European countries, the United States of America, Japan, Singapore, and Australia. The project also collected the information of the applications of landfill entry controls, especially about reclamation ground and seawater environment simulation. Besides, this study also compared 5 different NIEA and CNS methods of leaching tests and revealed the current application of waste final disposal and reuse. In addition, the document translation of Australian AS 4439.1, AS 4439.2, and AS 4439.3, and Japanese announcement of JLT 13. In order to compose an environmental leaching procedure, Australian method ASLP was used as the main framework for seawater leaching tests.
The international waste resource administration focused on the environmental impact due to material life cycle. As for soil and groundwater, leaching tests are the most important methods for assessing environmental impacts. Leaching tests are not performed with single test, condition, or uniform standards for waste resource treatments. In the long run, the European methods of integrated leaching tests, compatibility tests, and on-site verification can be used as a reference to establish the waste resource material controls. As for the entry control of the waste resource treatment, the experience from the countries like Japan, Australia, and New Zealand can be used with soil standards, drinking water standards, and wastewater standards to establish new entry control guidelines. The existing analytical methods can be used or modified to work with the policy of the reclamation ground.
