Food waste is the amount of food that is not eaten in each of the meals that we have. It comes with every meal. It's in every meal.

Why is there food waste? Wide eyes and narrow stomachs. It's not a good idea.

A few days ago, I was having lunch at a cafeteria near Mei Lam in Tai Wai, and there was a table of four or five students who got up and left after eating, but when I looked at them, I saw that they had ordered a couple of cups of frozen drinks, which were full, that is to say, they hadn't been consumed at all, and so they had turned into food waste, do you understand that? Organic waste generated in daily life can be called food waste, including all waste before and after food preparation, and even expired food can also be called food waste. Food waste is easy to rot, produce odor and attract mosquitoes and flies, and it is the biggest source of landfill odor, methane gas and seepage water. When it is stored temporarily in the family, it will stink within a short period of time and cause nuisance. Although the nature of food waste varies according to season and region, its basic properties are shown in the table below. Food waste is not suitable for incineration due to its high water content and low calorific value. In particular, due to the characteristics of the national diet, the salt content (sodium chloride NaCl) in food waste is high, which may be a potential source of dioxin. If buried, it may cause odor and seepage of water and other secondary pollution problems, so food waste will be classified and recycled as the best way to deal with the waste.
