Cost per life-year saved (CPLYS) is estimated for the control of the emission of dioxin-like compounds (PCDD/Fs and Co-PCBs) from municipal waste incineration plants. New emission standards for dioxin-like compounds are to be brought into effect in Japan at the end of 2002. Most of the municipal incineration plants are taking measures to comply with these new emission standards, which include improvements in combustion, control of the temperature of flue gas, and treatment of emission gas. The cost of the measures that will be taken from 1999 to 2002 is predicted for 1,655 plants on the basis of the cost of the measures actually taken in 1997-98, the concentration of dioxin-like compounds in emission gas in 1998, and the new emission standards to be applied in 2002. The investment cost is estimated to be 350 billion yen, the annual value of which is 66 billion yen. The increase in annual running cost is 14 billion yen. The total annual cost is 81 billion yen for reducing 1.9 kg-TEQ of dioxin-like compounds. The reduction of risk is estimated in terms of Loss of Life Expectancy by using mathematical models for exposure assessment. The resulting CPLYS is 160 million yen. This CPLYS is compared with those for other risk control policies.
