Abstract

Thermal generation facilities (TGFs) play a vital role in supplying heat to industrial manufacturing processes. In addition to fuel consumption, the majority of which are fossil fuels, TGFs produce bottom and fly ash (BFA) that could be utilized. The objective of this study is to assess the production and management at source of the BFA to propose appropriate management solutions. Based on HEPZA’s database, a questionnaire survey was conducted among 179 enterprises. Data was analyzed using descriptive statistics. The result revealed a total BFA production of 1,606.22 tons per month. At most enterprises, the bottom ash and fly ash were not separated. 33 companies involved in the collection, transportation, treatment, and recycling of BFA at 61 enterprises, showing a dispersed BFA handling system that may disadvantage the control of BFA pathways for reuse. This study proposed solutions to enhance BFA utilization via managing the BFA at source as well as the collection, transportation, treatment, and recycling facilities.
