認住呢條魚骨——廚餘處理
都市固體廢物收費（垃圾徵費）是目前城中熱話之一。政府引入此制度是想藉此作為「減廢政策」的重點工具，祈盼社會各界、香港市民能夠珍惜資源，實踐源頭減廢及乾淨回收，以舒緩目前龐大的垃圾棄置量的問題。
為配合「減廢政策」的推展，環保署一直推出多項措施，而一般市民大眾除了關心「徵費制度」如何落實外，相信日常生活所產生的廚餘處理會是更貼身的議題。根據環保署資料，現時香港每天產生約3,584公噸廚餘，其中三成來自工商業，其餘七成來自家居，可見如何消減家居廚餘確是政策成效的關鍵之一。
環保署早於2012年就成立了「惜食香港督導委員會」，主力推動社區關注香港廚餘管理的問題。在工商界層面，委員會大力推行「惜食約章」及「咪嘥嘢食店」計劃，鼓勵商戶採取措拖與顧客共同從源頭減少廚餘，培養市民的「惜食、減廢」文化。
而在家居方面，署方積極推展「廚餘收集先導計劃」及建立「有機資源回收中心（O PARK 1）」，在公共屋邨及私人屋苑放置「智能廚餘回收桶」，回收家居廚餘，再運往「O PARK 1」進行「轉廢為能」。
「智能廚餘回收桶」與一般紫色的回收桶一樣，桶上印有一條魚骨的圖案，不過「智能廚餘回收桶」具備物聯網功能，當桶內廚餘達七成滿，系統會自動通知清潔人員更換內桶，因此每個廚餘桶大致可供最少500個住戶使用。
按環保署資料，目前全港約七成（149條）公共屋邨已安裝527部「智能廚餘回收桶」，而私人住宅樓宇的回收桶亦達109個。署方估計到2024/25財政年度，回收桶的數量將增至逾300個，大大提升回收的成效。雖然報章上近日有報道指出部分回收桶出現爆滿或機件故障，但署方已回覆此情況只屬少數，逾99%廚餘桶仍運作正常。
「有機資源回收中心（O PARK 1）」位於大嶼山小蠔灣，於2018年投入服務。回收中心採用「厭氧分解技術（anaerobic digestion technology）將廚餘轉化為生物氣（biogas）以作發電，供中心內的機器設備使用；而過程中產生的殘餘物亦可轉為堆肥，作農業肥料之用（中心內設有農場——O Farm，更僱了農夫示範以堆肥種植的效用）。目前中心每日可以處理約200公噸的廚餘，第二期「有機資源回收中心（O PARK 2）」亦已在新界北區的沙嶺興建中，預計於本年內啟用，屆時可處理多達300公噸廚餘。
除了「有機資源回收中心（O PARK ）」外，環保署於大埔及沙田污水處理廠亦設有「廚餘 / 污泥共厭氧消化試驗計劃」，分別每日可處理50公噸廚餘。因此，整體設施的廚餘總處理量達每日600公噸。
雖然這個數字跟香港每天廚餘生產量仍有一段距離，但千里之行，始終足下，源頭減廢始終是處理固體廢物的不二之法，就讓我們身體力行，為環境保育負上一份責任和付出一分貢獻！

廣東道
二零二三年一月 第一期
廣東道
新年快樂！
以往每逢聖誕平安夜、元旦除夕，廣東道都有倒數活動，熱鬧非常！如同美國紐約的時代廣場倒數一樣盛大。
廣東道給人的印象，可能就是節慶活動、名店林立、高檔消費品的集中地。你可知道原來廣東道還有很多的面貌呢？
廣東道全長三公里多，由尖沙咀開始，一直延伸至太子，與荔枝角道相接為止。而整條道路並不是由頭連貫到尾，而是被分拆成大概四段道路：（一）尖沙咀天星碼頭至渡船街、（二）佐敦道九龍佐治五世紀念公園至眾坊街、（三）東莞街至石龍街油麻地果欄、及（四）窩打老道至荔枝角道，一共橫跨尖沙咀、油麻地和旺角三個地區。
第一段是大家最熟悉的名店區，西九文化區的戲曲中心亦坐落其中；第二段是玉器店的集中地，雖然部分玉器店已搬到甘肅街的玉器市場之內，但仍有近百的批發商留在這裡；第三段只是一段約五十米的短街，南接駿發花園、北達油麻地果欄——果欄極具傳統墟市特色，且集生果批發和零售於一身，全盛時期共有三百多間果欄店舖聚集於此；第四段則與五金、電器、建材相關，油麻地窩打老道至旺角山東街這段多集中五金、電器，而旺角道至荔枝角道就以木材、天花建材為主。這兩段之間的廣東道卻是兩旁整齊的街市排檔，以販賣生果為主；每當華燈初上，這裡小販高嚷叫賣之聲此起彼落，星斗市民爭相揀選平價生果，滿溢著草根民生的氛圍。
四段廣東道的商店檔次、種類極盡不同，卻都各從其類，集聚經濟效益之現象清晰可見。大家平常逛街之時，不妨多留意兩旁的店舖特色，或許也會發現很多有趣之事。
