dc.description.abstract | Due to needs of construction, the tremendous amount of waste soil had been produced in Taiwan every year. In the sequence index of waste soil, B6, containing more than 30% of sludge or water, and B7 ,Bentonite conducting by settling slurry wall, are extremely difficult to dispose firm because of badly efficiency in recycling and high expenditure in dealing fee. Therefore, it has been tackled illicitly and disposed illegally, and then contaminating environment seriously.
For encouraging constructors towards the goal of sustainable city and green living three systematic steps are revealed in this research:1. Exploring the source and disposal of waste soil. 2.

Discussing the possible usage and reclamation of waste soil, embodying with current techniques and experience.
Moreover, to approach the goal, two main phrases had been taken. 1. Researching the capacity of tackling sludge and waste soil dispose in soil-recycling fields and terminal distribution. In this stage, several current municipal laws and acts had been evaluated, and then analyzed the discrepancy of declaration amount in waste soil with different codes. 2. In the final stage, after interviewing and collecting suggestions abstracting from local governments and constructors, the Soil Plastic-limit Disposal Code, emphasizing on relative equipment of dealing waste soil and terminal disposal, had drafted in order to improve the quality and efficacy of soil-recycling fields.
