濟南一企業利用蟑螂回收食品垃圾

In a food waste recycling plant in Zhangqiu district in Jinan, Shandong Province, piles of food waste, freshly delivered here from local restaurants and canteens, are waiting to be recycled - by cockroaches.

在山東省濟南市章丘區的一間食品垃圾回收工廠裏，從當地餐館和食堂剛送過來的成堆食品垃圾正在等待着被蟑螂回收利用。

After being ground, the food is pumped into glass containers in the plant through a pipe, then devoured by millions of cockroaches.

在被磨碎之後，這些食物通過管道輸送到工廠裏的玻璃容器中，然後由數百萬只蟑螂吞食。

For most people, cockroaches are pests that can leave an offensive odor, transmit viruses on their body surfaces and taint food.

對於大多數人來說，蟑螂是一種可以留下異味、傳播身體表面的病毒並且污染食物的蟲子。

But Li Yanrong, a entrepreneur from Jinan, has successfully turned them into professional recyclers after spending years studying the notorious insect.

但是來自濟南的企業家李延榮，在花費數年時間研究這些臭名昭著的昆蟲後，成功地把它們轉變爲了專業的回收利用者。

At the recycling plant, the roaches feed on 15 tons of food waste every day, more than a third of all food waste generated from Zhangqiu's restaurants and canteens.

在該回收工廠裏，蟑螂每天會被餵食15噸的食品垃圾，這一數字超過了章丘當地餐館和食堂產生的食品垃圾總量的三分之一。

Previously, most of it would have ended up in landfills, causing environmental problems for the areas where they were buried.

在以前，這些垃圾大部分都進了垃圾填埋場，對填埋地區造成了環境問題。

Now, the roaches can not only decompose the waste leaving little residue, but also turn it into something useful.

如今，蟑螂不僅可以分解垃圾留下微量殘留物，而且可以把垃圾轉變爲有用的東西。

After the cockroaches die, their bodies, known to have high protein and nitrogen levels, will be made into cockroach powder to be used as a protein source for animal feed.

在這些蟑螂死後，它們的身體富含高蛋白和氮，將被製作成蟑螂粉，以作爲動物飼料的一種蛋白質來源。

In 2014, there were only 400 kilograms of cockroaches in the plant. In 2015, the number surged to four tons, and this year, it's projected that over 3,000 tons of cockroaches will be produced here.

2014年，工廠裏只有400公斤的蟑螂。2015年，這一數字猛漲到4噸，今年計劃將有超過3000噸的蟑螂在這裏產出。
