them into new materials.
(一些不可更新的資源，例如銅和可以回收鋁，或被重複利用擴大供應。回收介入收集廢料和處理他們成新的材料。)
For example, discarded aluminum cans can be crushed and melted tomake new aluminum cans or other aluminum products.Reuse is using a resource over and over in the sameform.
(例如，放棄鋁罐可以被擊碎和被熔化做新的鋁罐或其他鋁產品。再用在同樣多次使用一種資源形式。)
For example, glass bottles can be collected,washed, and refilled many times . But energy resources such as oil and coal cannot be recycled.
Once burned, their energy is no longer available to us.
(例如，玻璃瓶可以收集，洗滌和重新裝滿許多次。 但是不可能回收能源例如石油和煤炭。
一旦燃燒，他們不再重複供給我們。)
