堆填同焚化的分別?

Advantage of landfill: chaeper to operate, usually a team of about 150 staff including truck operator, landfill site foundation preparation, lab technicians,management, etc.can operate a landfill sites. Can treat large amount of refuse in one time. Can recover methane gas for electricity generation or other use. Continuous operation.

Disadvantage: occupy large piece of land which takes many years for the refuse to disintegrate. Foundation preparation , i.e. levelling of the land and laying of impermissible material layers. Contaminated material will remain in soil for many years. Need to treat contaminated liquid and methane gas.

Advantages of incinerator: Can treat highly toxic material (such as bioxin, disintegrate it by high temperature) and waste that regulatory required must be treated by incinerator such as medical waste. Occupy smaller piece of land. Can reuse heat generated.

Disadvantages of incinerator: expensive to set up and operate. Need to maintain regularly, means it will stop operation for a period of about one week every year for maintenance and repair. Need fuel for maintaining combustion, means high running cost. Need to build dust collector and gas scrubber to maintain emitted gaseous waste within limit.

That's all I can remember. May not be totally correct.

垃圾堆填區，又稱填埋場、填埋區和掩埋地等，是集中放置垃圾的地方。

[編輯] 選址

遠離民居
山的高度適中（過高會令堆填工作困難）
山上石質堅實
水陸交通方便

[編輯] 管理
有機物若沒有妥善處理，將自然分解，會放出沼氣、污水。

污水：要有污水收集管，舖放防滲層墊層，興建化油污池。
沼氣：可能引致氣體爆炸、火災（例如美國每年有約8300宗火災因此而起[1]）
亦有地方善用沼氣發電，例如台灣山豬窟垃圾衞生掩埋場。
