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.
