內政部於民國80年5月2日頒訂「營建廢棄土處理方案」將剩餘土石方納入管理，迄今已有十幾年之久。不僅北部縣市剩餘土石方(以下簡稱餘土)問題未曾歇止，全國各地遭遇相同困難，且部份地區更為嚴重，甚至破壞環境景觀，危及公共安全。使得政府不得不重視此一問題，行政院先後責由行政院公共工程委員會成立北部跨縣市協調小組及內政部成立營建剩餘土石方協調小組，藉由跨部會成立之專案小組負責處理剩餘土石方問題。86年由財團法人工業技術研究院(能源與環境研究所)建立「營建剩餘土石方資訊服務網站」，89年成立「營建剩餘土石方資訊服務中心」，協助內政部營建署推動執行「營建剩餘土石方處理方案」 。剩餘土石方問題仍然存在成為工程執行的最大阻力，有不少工程人員為此觸法身陷囹圄，工程界談土色變。台灣四面臨海，剩餘土石方問題無法解決，值得深入探討。 在都市及人口集中之處，建物興建或公共工程的開闢，而產生之營建剩餘土石方問題仍然存在。幾年來所造成台灣地區之生態環境的破壞及公共安全之危害更顯嚴重。先進國家均趨向於將營建剩餘土石方分類回收、減量及再生利用，所以處理剩餘土石方問題自是刻不容緩。 面對國內營建剩餘土石方處理問題，工程界無法迴避，如善加處理並推廣再生利用，又能減少自然資源消耗，可謂一舉多得。有關營建剩餘土石方處理問題，已不容再延遲。本研究從法規、管理、技術、經濟切入研擬對策，冀能有所助益。 The Ministry of the Interior officially promulgated the “Project of Construction Waste Clay from Construction Sites” on May 2, 1991. The Project has been in enforcement for more than a decade since then. Regrettably enough, nevertheless, the problems of residual clay out of the construction sites in all counties and cities in northern Taiwan (hereinafter referred to as Residual Clay) have remained unsolved. The Residual Clay has even become nationwide problem, getting from bad to worse in certain areas, critically spoiling the environments and endangering public safety. The government cannot help but seriously watch such problem. Via Public Construction Commission, the Executive Yuan (the Cabinet) has set up the Cross-County/City Coordinating Panel, and the Ministry of the Interior has set up the Residual Clay Coordinating Panel to exclusively shoulder the responsibilities to solve the Residual Clay problems. The Energy & Resource Research Institution founded the “Residual Construction Site Clay Information Service Website” in 1997 and further set up the “Residual Construction Site Clay Information Service Center” in 2000 to help the Ministry of the Interior enforce the “Project of Construction Waste Clay from Construction Sites”. Today, the Residual Clay remains the top obstacle against enforcement of the construction project, leading quite a few project personnel into jail. Such problems virtually frighten the construction realm. On this sea locked island of Taiwan, we virtually cannot afford to ignore such pending problem any longer. The Residual Clay problem remains serious in construction sites for buildings or public projects, in particular in urban and highly populated regions. Such problems have increasingly jeopardized the ecological environments and public safety. We cannot delay any further to solve such problems with reference to advanced countries where they solve the Residual Clay through classified treatment, recollection, minimization in volume and reuse. The entire construction realm could no longer shirk the responsibility and is supposed to heavily promote reuse of such residual clay. Such efforts would yield multiple benefits through reduced waste of natural resources. Once more, all people in the public project and construction fields are urgently required to solve such critical problem. The present study is conducted through law, management, technology, economics and is hoped to benefit the entire society and country.
