Abstract: This study presents a Quantitative Risk Assessment (QRA) of thermo-chemical Waste-to-Energy (WtE) technologies, specifically incineration and gasification, by utilising simulation tools PHAST and SAFETI. Hazard identification, consequence analysis, and risk assessment were conducted to compare the safety profiles of these two technologies and proposed risk reduction strategies for a safer design. Accident scenarios were modelled for Tuas South Incineration and Borregaard Gasification facilities to analyse dispersion and effects of fire and explosion. Hazards indicated that only gasification exclusively involves flammable releases because it reacts as a partial combustion, with carbon monoxide and hydrogen as flammable byproducts. Results revealed that while gasification posed lower risks of toxic release, incineration exhibited lower fire and explosion risks. Individual risk fell within the ALARP region for both plants, with societal risk showing incineration falling within ALARP with a total risk int
