Integration with Local
Community: A Key to Success
A modern incinerator is more than just a
solid waste processing facility. It can also
serve the community in many other areas.
Apart from providing surplus electricity to
nearby residents, the generated low pressure
steam is also utilised for green houses, cafés,
heated swimming pools and spas, district
heating, etc. while some of the facilities
are free of charge for the nearby residents
to use. In some cases, the incineration
plant can become an important landmark
of the district as well. For example, at the
Beitou Refuse Incineration Plant in Taipei,
there are observatory, revolving restaurant
and community convention center on the
120m-tall chimney, attracting tourists and
visitors.
Still, many people voice out their concerns
about the potential health risks generated
from the MSW incineration. In fact, the
exhaust gases would undergo a series of
treatment facilities, such as electrostatic
precipitator, selective catalytic reduction,
etc., to control the emission of harmful
substance like hydrogen chloride, sulphur
dioxide and nitrogen oxide, while high
temperature inside the incinerator ensures
complete destruction of dioxins. Thereafter
the cleaned exhaust gases are discharged

融入社區:成功關鍵
現代焚化爐不僅是固體廢物處理設施,更可
在各方面照顧社區所需。除了為附近居民提
供電力外,焚化爐產生的低壓蒸氣更可用於
附近的溫室、咖啡室、恆溫游泳池及水療設
施、區域性暖氣供應等。焚化爐更可以成為
地區重要地標,以台北北投垃圾焚化廠為例,
120 米高的煙囪設有觀景台、旋轉餐廳及社
區中心等,成為當地旅遊景點。
話雖如此,很多人仍擔心焚燒都市固體廢物
影響健康。事實上,垃圾焚化釋出的氣體會
經過一系列處理,如靜電除塵及進行選擇性
催化還原等,以控制氯化氫、二氧化硫及氮
氧化物等有害物質的排放量,而焚化爐的高
溫環境亦能確保完全消滅二噁英。及後,經
淨化的廢氣,通常在 100 至 150 米高的煙囪
排出,以減低對附近民居的影響。焚化後的
殘餘物多數會運往堆填區,部分地區則會用
作建築材料。有部分焚化廠會設有監察裝置,
於網上公布空氣監察數據和所產生的電力,
增加焚化爐對公眾的透明度。新加坡大士南
焚化廠排放數據就法例要求相比下的出色表
現,正正展示現代焚化技術在控制空氣污染
上的高標準。
毫無疑問,現代垃圾焚化轉化能源已是發展
成熟的技術,是直接、有效並可持續的處理
廢物方式,產生能源帶來實際效益之餘,亦
在整體減碳及其他方面貢獻社會。因此,當
務之急是教育和宣傳世界各地成功應用現代
焚化技術的經驗,從而爭取廣大市民支持興
建焚化爐。這肯定是達致藍圖所定的目標,
以及為香港實現可持續未來的關鍵一環。

at a chimney of typically 100-150m tall,
minimising the impact to local residence. In
some places, the residues from burning are
used as construction materials while most
of them will be sent to landfills. Some plants
are also equipped with online monitoring
equipment on the air monitoring data as
well as the amount of generated electricity
to increase its transparency to the public.
The emission data for the Tuas South
Incineration Plant of Singapore shows a
remarkable performance against the limits of
relevant regulations, demonstrating the high
standard of modern incineration technology
in controlling air pollution.
There is no doubt that the modern waste to
energy incineration is already a good and
mature technology, and it is a direct and
effective way to achieve waste sustainability
by turning waste to energy for beneficial
use and contributing in the overall carbon
reduction and many other aspects for the
community. Therefore, the next important
step is the education and promotion of the
successful experience of modern incineration
technology around the world, so as to gain
public support for building an advanced
waste to energy incinerator, which will
definitely be a significant part in reaching
the waste management targets set in the
Blueprint and achieving a more sustainable
future for Hong Kong.
