How Typhoon Mangkhut waste could help build Hong Kong
- If the government makes provisions for the composting of fallen leaves, they could be used to make soil conditioner
As a landscape professional, I understand complexities and difficulties of “recycling” the waste wood from Typhoon Mangkhut. Unfortunately, we appear not to have the necessary facilities available at the moment for such a massive task (“How trees in landfill tell the story of Hong Kong”, November 18).
However, and I’m sure Professor Jim Chi-yung and others in the industry will agree, leaves are not “litter”. Hong Kong must embrace the composting of fallen leaves. These should never be bagged and sent off to landfill.
The Leisure and Cultural Services Department, Environment Protection Department and related departments need to urgently shift gear and use this valuable organic compost in our ever-increasing infrastructure developments. Soil mix is currently 75 per cent CDG (completely decomposed granite) and 25 per cent soil conditioner. The former is cheap and easy to obtain; the latter is not.
I urge the government to embrace the simple recycling of fallen leaves and help develop our sustainable future. This valuable natural resource does not belong in a landfill.
