Insects could help turn beer waste into beef
Despite The Economist’s best efforts, eating insects has not yet caught on among humans. Luckily, livestock are less fussy. Insects are a nutritious source of animal feed. Of course, insects also need to eat. Most insect-rearing has thus far relied on surplus chicken feed. But if insect-reared meat is to take off, new sources will be needed. A study published in Applied Entomology, a journal, proposes feeding them the beer industry’s waste products.
Around 185bn litres of beer are consumed worldwide each year. Each litre produces between three and ten litres of wastewater full of barley and yeast, a mix rich in protein but deficient in carbohydrates. Because insects in the wild typically rely on carbohydrates, it was unclear if they would take to the waste. But researchers found that they ate it happily. Slaughterhouses and sugar-beet could also provide sources of plentiful, protein-rich waste for insects to feast on.

尽管《经济学人》尽了最大努力，但吃昆虫尚未在人类中流行起来。幸运的是，牲畜并不那么挑剔。昆虫是动物饲料的营养来源。当然，昆虫也需要吃东西。到目前为止，大多数昆虫饲养都依赖于多余的鸡饲料。但是，如果要让昆虫饲养的肉突然获得成功，就需要新的来源。

发表在《应用昆虫学》（Applied Entomology）杂志上的一项研究建议：给它们饲喂啤酒工业的废料。
Around 185bn litres of beer are consumed worldwide each year. Each litre produces between three and ten litres of wastewater full of barley and yeast, a mix rich in protein but deficient in carbohydrates.
全球每年消费约1850亿公升啤酒。每公升产生三到十升富有大麦和酵母的废水，这种混合物富含蛋白质但缺乏碳水化合物。

由于野生昆虫通常依赖碳水化合物，因此原本不清楚它们是否会开始喜欢废物。但是研究人员发现，他们吃得很开心。屠宰场和甜菜也可以为昆虫提供丰富的、富含蛋白质的废物来源，供它们尽情享用。
