碩士 / 國立雲林科技大學 / 營建工程系 / 102 / In early years of domestic garbage incineration, bottom ash was normally buried. Due to the fact that Taiwan is a small island with many population, including NIMBY effect; getting sanitary landfill site is not easy.Currently there are 24 operating large garbage incinerators in the country. The 700,000 bottom ash, caused by incineration, counts for 10 percent of garbage disposal, which is a huge amount.So how to effectively deal with bottom ash and fly ash, generated by incineration? Except for the basic need of decreasing bury space, reborn them and make them into useful resource, furthermore, plan how to use the useful resource to melt, are the targets that garbage disposal field needs to get ahead.
Since the completion of Nanliao Fishery Harbor, the coastal erosion of Hsinchu Nanliao coastline is getting worse, caused by harbor structures’jetty effect, which blocks effects of drift sand. Except for planning related anti-erosion, relevant government officials actively think how to combine anti-erosion and bottom ash reborn aggregate to melt, also damage the environment the least.
Currently domestic bottom ash reborn products, mostly we use graded roadbed filling, CLSM, and bricks adding materials methods; never applied to seawall and seas.So to find new melting methods, we use bottom ash reborn products as pellets, and ask professional suppliers to use current seawall form to repress experimental samples, adding the research evaluations of fundamental physics, chemical properties, in-situ and laboratory test, TCLP dissolution test, we understand the possibility of causing major effect to the sea. We verify the possibility of using bottom ash reborn material on the unreinforced concrete structures of the coastal seawall as the reference follow-up bottom ash reuse melting methods.
With the experiments stated above to verify the seawall, made by bottom ash material, after three months’ in-situ and laboratory test and analysis, from 2012 September to 2013 March, no matter the parts of physics or chemistry, the results all meet normal building materials. Furthermore, based on the quality control procedure of bottom ash reuse, we can also achieve current regulation of bottom ash management, and we can still make progress.
We also collected former Hsinchu Nanliao coastline erosion control plans and analyzed pros and cons of coastal erosion planning from lately relative planning government officials. We suggest follow-up government officials to consider using integrated methods, and adding the most efficient method of integrating bottom ash reborn material to their planning methods.
