TMIAH director Yan Yi-feng points out that the plastic doggy poop bags are made of a special biodegradable material to keep environmental pollution to a minimum in case they are disposed of improperly. The chemical composition of the bag materials is marked clearly on the outside to remind individuals that these bags should not be used for food storage or taken to be used as garbage bags back home.
動檢所長嚴一峰表示，狗便清潔設備提供的抽取式塑膠袋含有特殊分解劑，可減輕對環境污染的程度，以防部分缺乏公德的飼主清完狗便後，隨手扔棄塑膠袋；塑膠袋外也註明相關成分字樣，提醒民眾勿以塑膠袋盛裝食物，或將塑膠袋攜回裝垃圾。
