Confronting food waste: restaurants eliminating food waste

Confronting food waste: restaurants eliminating food waste

对抗食物浪费——餐馆在努力


In recent decades, food waste has risen as a serious issue around the world. It is roughly calculated that worldwide 1.3 billion tons of food are wasted. In the US, the number is around 56 to 72 million tons. (2)

在21世纪,食物浪费已经成为一个非常严重的社会问题。粗略估计,全球每年多达13亿吨食物被浪费。其中美国的贡献在5600万至7200万吨之间。


The US Environmental Protection Agency (EPA) defines food waste as “Uneaten food and food preparation wastes from residences and commercial establishments such as grocery stores, restaurants, and produce stands, institutional cafeterias and kitchens, and industrial sources like employee lunchrooms.” (3)


“Restaurants should be responsible for the majority of food waste outputs”

“Restaurants should be responsible for the majority of food waste outputs”, said Elizabeth Balkan on PBS Newshour (4). In her opinion, leftovers on people's plates and post-consumer waste like bones and species are the main two sources of food waste. During her talk, she mentioned the negative environmental impact on food waste landfill which releases a large amount of methane– another greenhouse gas which is up to 86 times more powerful than carbon dioxide. What is worse, global warming is not only a problem when food waste is sent to landfill. An Australian scientist (5) claims that the leaching and runoff from dumped food waste containing a massive amount of Nitrogen can contaminate rivers and groundwater by the process of eutrophication.

美国环境保护署(EPA)将食物浪费定义为:“未使用食物/食物原料垃圾,源自住宅或商业场所(如杂货店、饭店、食品摊位、食堂或厨房)和工业场所(如员工餐厅)”。“饭店需要为大部分的食物浪费负责”( Elizabeth Balkan 在 PBS Newshour )在讲话中她谈到废弃食物的另一个负面影响——填埋后产生的甲烷。甲烷比同为温室气体的二氧化碳温室效应强86倍。填埋还有另外的负面影响:一位澳国科学家声明,废弃食物中富含的氮将使临近的水体富营养化。
