This project aims at improving the management of bottom ash recycling, conducting relevant works of bottom ash recycling project, providing suggestions to the Environmental Protection Administration (EPA), and maintaining and strengthening the operation of Recycled-Aggregate Management System (RAMS). Further explanations concerning this project are as follows:
1.To improve the management of bottom ash recycling, this project designed a questionnaire for local environmental protection departments, incinerators, recycling facilities, reprocessing facilities and engineering sectors to gather relevant advice. Through analyzing the data collected from the questionnaires completed by aforesaid respondents, six questions for review and three suggestions for improvement were proposed and compiled in this project to make the management system more comprehensive. And therefore, an amendment draft on the “Methods Governing Recycling Remains of Incinerators” was proposed.
2.To keep up to date with the latest progress of international community, this project compiled relevant regulations on the environmental aspects of incinerator bottom ash aggregates (IBA aggregates) from six countries, and analyzed domestic standards set for chloride ions, pH, and sulfate. Results showed that the crushed material collected from IBA aggregates meets the standards of “Methods Governing Recycling Remains of Incinerators” and its engineering performance also meets relevant requirements through analyzing and testing. Therefore, such material can be included into remaining earthwork as alternative material to natural aggregates and preserve natural resources.
3.To enhance the engineering application techniques of IBA aggregates, a draft on outline specifications for public construction for “regenerated low-density pervious concrete (RLDPC)” and “asphalt concrete pavement” were completed. This project also edited the manual for “Subbase Aggregate,” and made a new manual for “Road Base and Embankment Filling.” Three sessions of specialists consultation meetings were held for the completion of these two manuals for the use of construction and relevant units.
4.To make Recycled-Aggregate Management System (RAMS) meet users’ demands, seven functions were established, eight times of security testing were conducted, fifty-six replies to users’ questions were made, forty-nine items for maintenance were provided, and two training programs were carried out to reduce error rate when operating the System. Besides, decommissioning of the old system DISP was completed, and RAMS provides services for users to search for information that was on DISP.
5.To effectively reduce the workloads that were put on the examining members, this project established items to be examined for the reuse of bottom ash; besides, this project also helped examine a project report (Kaohsiung city).
6.To research and analyze the future management strategies of bottom ash in Taiwan, relevant information from five countries were compiled in this project. Three future management strategies for the reuse of domestic bottom ash were proposed through analyzing five challenges and difficulties encountered when urging the use of IBA aggregates.
