We hereby ask our Government to directly address the growing problem of disposing of PLA Plant-Plastics in a responsible, sustainable & eco-friendly way. Please extend the capacity of existing and future composting facilities to process plant plastics from Hong Kong’s restaurants and general waste streams and enforce correct labelling for waste separation to mitigate Hong Kong’s waste crisis.

針對目前日益嚴重的處置植物塑膠 (PLA)的問題,我們鄭重請求政府重視並以負責的、可持續性的 & 環保的方式直接處理。請求政府加強目前以及未來廚餘處理設施的容量,處理來自香港餐廳以及其他廢物渠道的植物塑膠,並實施廢物正確標記及分類方案,以此改善香港的廢物危機問題。


About 3,400 tonnes of food waste is disposed of in Hong Kong every day, that’s 100,000 double-decker buses by weight EVERY YEAR. Hong Kong’s main composting plant, the Organic Waste Treatment Facility (OWTF) Phase 1, can only handle 200 tons of food waste a day, with the second OWTF to manage 300 tonnes a day by 2021. This barely scratches the surface of the problem we face.


Polylactic acid, (PLA) is a bio-polymer. PLA is made from the starch found in plants including beets, sugar cane, and tapioca. Starch is a natural polymer, a white, granular carbohydrate produced by plants during photosynthesis. This starch can be made into bio-plastics, or ‘Plant Plastics’. When exposed to heat and moisture in industrial composting facilities, it can then be composted like other organic matter. 


We already know that Hong Kong’s capacity to recycle conventional plastics such as PET is limited, and the fact that Mainland China now heavily limits the amount of recyclable waste imported causes these valuable materials to be sent to landfill.


As the environmental crisis we are facing surrounding conventional plastics is becoming more and more apparent, many eco-conscious restaurants and businesses alike are turning to alternative packaging, such as Plant Plastic, in an attempt to mitigate damage. These Plant Plastics are widely advertised as ‘biodegradable’ with the ability to be composted.


However, there is HUGE disconnect between the producers of these plant plastics and the users & governments who are responsible for their waste disposal and management. Plant Plastic cannot be recycled, and requires industrial composting facilities to break them down efficiently. If the composting infrastructure is not in place to recover the bio-material from a plant-based cup, it's really no better than your toxic plastic water bottle. They are ending up in landfills and the open environment, where they take decades to biodegrade. 


Hong Kong’s Environmental Protection Department has not yet recognised the potential for collection and composting of Plant Plastics from restaurants or other industries. The speed and capacity for which the Hong Kong government is planning industrial composting facilities is not fast enough to deal with the waste crisis we face.



Of course in an ideal world, we’d eliminate the use of single-use packaging full-stop, but unfortunately we aren’t quite there yet, and it will take some time for all businesses to become zero waste. We have an alternative to toxic conventional plastic NOW and we must harness it.


The government must recognise the growing problem surrounding conventional plastics, and facilitate businesses to move to alternatives through supporting the composting of Plant Plastics at current and future government facilities. The current government facilities operate at 30-60C, optimal temperatures for PLA to break down

政府必須充分認識到傳統塑膠產生的問題越來越嚴重,通過現有的和未來需建立的政府機構支持植物塑膠處理,幫助鼓勵商家開始使用植物塑膠。目前的政府機構在30-60C, 適宜的溫度下運行PLA的分解。

The collection of PLA from restaurants could be facilitated through the FEHD or independent contracted bodies, such as Baguio or HK Recycles. There is already a growing alliance of 14 restaurants spread out over Hong Kong Island, named the ‘Zero Waste Alliance’ who use PLA and are willing to participate in any trial schemes as a collective.

從餐飲行業收集的PLA可以通過FEHD或者其他獨立的機構進行處理,類似碧瑤綠色集團有限公司,或者HK Recycles。現在已經有一個由14家餐廳組成的不斷擴大的組織 “零廢聯盟Zero Waste Alliance”正在使用PLA, 並且願意一起參與任何嘗試計劃。

This would accelerate the solution of Hong Kong’s waste problem by solving two issues at once - the transition from Conventional Plastics to Plant Plastics, and the harnessing of valuable energy from food and PLA waste otherwise lost.

這將通過同時處理兩個問題,加快解決香港廢物危機的問題的辦法 – 首先從使用傳統塑膠轉型到使用植物塑膠,同時利用好從食物以及PLA廢物中本來會損失的寶貴能源。
