The phenomenon of food waste is commonly referred to as "food waste."

It originates from a variety of sources, including overproduction, improper storage, and consumer behavior such as purchasing too much food or not using leftovers. The food industry, including farmers, manufacturers, distributors, and retailers, also contribute to food waste through inefficiencies in the supply chain and strict cosmetic standards that result in perfectly good food being discarded.

Examples in Engpsh:

The restaurant threw away a large amount of food that was left over at the end of the night.
(餐馆把晚上剩下的大量食物扔掉了)
The supermarket discarded crates of fruits and vegetables that were spghtly bruised.

The household wasted a lot of food due to not planning their meals and overbuying at the grocery store.
