To shine a light on why there are so much food waste in Malaysia, apparently inedible waste like big fruit peels are considered as food waste in Malaysia. To quote the report:

>In a 2010 household waste composition analysis in Bandar Baru Bangi, Malaysia, food waste was split into three categories: “Unused food”, “General kitchen waste” and “big fruit peels.” The latter category is particularly relevant to Southeast Asia, where large fruits such as durian or jackfruit will lead to substantial inedible waste.

Malaysia is a big producer of fruits with thick and heavy inedible peel/shell, most notably are durian, jackfruit, mangosteen, coconut and so on. Also referring the same analysis:

>What is more notable is that “Unused food” accounted for some 18 per cent of total food waste in those households, a substantial minimum share of food waste that was edible.

The point is, data collection varies from country to country, and visualization like this doesn't effectively represent the truth of the matter.
