regulations. In addition to the emission of odor, incinerator without air

of sulfur and nitrogen oxides. (Vesiling P. A., 1994)

No additional odor equipment is required for our selected incinerator type
(Fluidized bed incinerator). Therefore, no eventual odor will be derived from the
incinerator. 流動床焼却炉を選択する場合、追加の臭気対策装置は不要。焼却炉からは臭気は派生しない。
No health effect on people living around
the Incinerator 焼却炉周辺に住む人々住民の健康被害はないと思われる
Human can be adversely affected by exposure to air pollutants in the ambient air.
In response, Japanese government (or EU or EPA) as developed an extensive
body of legislation, which established health based standards and objectives for
a number of pollutant in Air 大気中の大気汚染物質への暴露により人体は悪影響を受ける可能性がある。そのため、日本政府(EUまたはEPAも同様)は空気中の汚染物質の量に基準値を設けている。

The presence of the incinerator will affect traffic in this area:
焼却炉による周辺地域における交通量への影響- Garbage truck ごみ収集トラック- Chemical distributions 化学薬品の移送- Ash transportation 灰の輸送
Therefore, this traffic may cause some disturbance (nuisances) to the
local residence: noise, exhaust gas, eventual odors from the Garbage truck,
交通量の増加に伴い、騒音や排気ガス、ごみ収集車からの悪臭など、周辺住民に悪影響(迷惑)を与える可能性がある。
