废品

The engine has been sold for scrap.

引擎被当作卖掉了。

They cleared out the junk room to make a tiny beds.

他们将间清理用作小卧室。

To keep its lumpiness and reduce the number of broken product seems a key step for the decrease of rejection ratio and raw material consumption.

There are many other ways to reuse the wastes. If we try our best to recycle the wastes, there will be less wasteless pollution in our life.

有再利用的方法。能尽力将回收再利用，将会大量少，周围的污染也会大大轻。
