Paper Title:
A Study for Substituting Part of Raw Materials by Bottom Ash in Portland Cement
  Abstract

The disposal and reuse of waste combustion residues has become a critical topic recently in view of the method of treating household wastes in a city, which has gradually changed to be incineration (major) and landfill (minor) in densely populated Taiwan, plus the difficulty of various wastes disposed by the Refuse Incineration Plant at Yilan County. To propose concrete recommendations as references for the local competent authorities’ policy for reuse of bottom ash, we researched and analyzed compositions of wastes and ingredients as well as leaching toxicity of bottom ash (accounting for 70% of waste combustion residues) which had been collected from the Li-Ze Incineration plant at Yilan, and transported bottom ash to a cement plant also at Yilan as an alternative material for Portland cement. The results in this study indicated quite a few products, with ingredients of bottom ash from an incineration plant, can be taken as principal compositions used in production of cement, and the capacity of bottom ash treated by the cement plant can be further expanded according to the quality of produced cement and bottom ash properly processed.
