'wasted' management

家居廢物收費 2010年前難實行
extracted from 明報 . 26.02.2008

【明報專訊】政府的減廢大計嚴重延誤,環保署長王倩儀承認,本港家居廢物難以按量收費,今年中開始會進行12至18個月的大型基線調查,完成後進行公眾諮詢,暫未能訂下落實推行收費的時間表。換言之,家居廢物收費不會在2010年前實行。

「按量收費」失敗而回

對於政府明確指出,本港首個焚化爐將於2014年投入服務,地球之友及立法會議員蔡素玉均批評,未做好源頭分類便焚燒廢物,只會浪費大量有用資源,是減廢政策的大倒退。

王倩儀昨出席立法會環境事務委員會,交代去年完成的家居廢物按量收費試驗計劃,結果顯示追查每戶生產廢物的源頭有困難,因此難以執行按量收費。

政府將於今年下半年重新展開一項基線調查,為期12至18個月,研究以劃一或定額方式徵費,初步構思以水費或差餉單評估每戶產生的廢物量及收費水平。她說,新加坡目前亦是以劃一方式收費,台北最初亦是以該方式收費,到市民適應後,才轉為按量收費。

議員批評減廢政策倒退

環境局長邱騰華強調,政府沒有忽略源頭減廢工作,強調徵費方式必須切實可行,試驗結果既顯示難以按量收費,因此要重新研究。他又指落實興建焚化爐需時,目前提出是合適時間。民建聯蔡素玉批評政府的減廢政策大倒退,認為以焚化爐「一燒了之」不能解決問題,民主黨李柱銘批評政府議而不決,推行收費無期。

政府早前公布,新一代焚化爐將於2014年運作,議員普遍關注選址對周圍環境及居民的影響。民建聯劉江華形容,本港擬興建的焚化爐「萬佛朝宗」,容量高達 3000公噸,與日本分散在各區的小型焚化爐不同,而該區亦有其他大型設施如電廠及堆填區等,擔心影響香港的空氣質素。環保署回應稱,目前科技可以將焚化過程產生的致癌物二噁英維持在極低水平,遠低於歐盟標準,不會對周圍居民有任何影響。

焚化爐計劃亦引起財團注意,青洲英坭執行董事莊善敦昨日親自到立法會旁聽,會後透露今日與環保署代表會面,建議採用該集團的「環保廢物融化系統」,將焚化爐設於英坭廠內,毋須額外撥出土地,較其他選址更環保及具成本效益。

Air Tree @ Madrid

The city of Madrid soon plans to add a striking new structure that will “climatically transform” its urban architecture. Designed by Urban Ecosystems, the Air Tree pavilion is to be built from recycled materials and will be 100% energy self-sufficient. Using photovoltaic cells, the Air Tree produces a substantial amount of energy, which is then sold back to the local electric companies, the profits being used for maintenance of the structure. The second byproduct is of course oxygen - hence the name ‘Air Tree’!

solar-powered bicycle rental booth in kassel



bicycle is having a revival in europe - more & more people are riding it to work/school and governments are promoting cycling as an alternative way to cut carbon dioxide output by transport.

this booth is powered by photovoltaic panels on the roof, making it more self-sustainable.
