  1. An ordinary citizen of Hong Kong

  2. Reasons for us to support incineration: - Effective - Safe - Economic way $$

  3. Effective • Much faster (time consuming) • Thermal desorption consist more steps Incinerator Thermal adsorptions

  4. Comparison Thermal desorption Incineration Thermal desorption (dioxins) Incineration(dioxins) (chemical waste) Incineration

  5. Safe • Dioxin can be effectively treated at the CWTC • Dioxins will be completely destroyed at 800°C • The level of the emission of dioxins in the CWCT on Tsing Yi Island will not affect human health • The risk of dioxin enter the food chain is low Dioxin

  6. Result for incineration of Residues containing dioxins (March 2005)

  7. Concentration of dioxin release in the chamber 0.08 0.0054 0.0004 0.00065

  8. Concentration of carbon monoxide release in the chamber 150 0.33 0.0 0.01

  9. The dioxin emission standard in Hong Kong is 0.1 ng I-TEQ/m3 which more stringent than the standards adopted in most advanced countries. AMBIENT AIR SAMPLERS

  10. Dioxin emission standard among different countries

  11. Dioxin emission standard among different countries 0.3 0.02 0.1 0.1 0.08 Hong Kong: the Chemical Waste Treatment Centre (CWCT)USA*1: Municipal solid waste incinerators (more than 35 tonnes per day)USA*2: Hazardous waste incineratorEU: Waste IncineratorsCanada: All new incinerators

  12. Economic • Since thermal desorption consist of more steps. Location of Chemical Waste Treatment Centre Chemical Waste Treatment Centre

  13. Conclusion Incineration Effective Economic way Safe
