Paper that is newspaper is recycled once again into newspaper. Copy paper is recycled into the notebook paper and toilet paper we all use. What about empty bottles? There are “returnable bottles” that we wash and reuse and “one-way bottles” that we can use only once. But one-way bottles are crushed and then made into new bottles. Finally, there are empty cans. Steel cans are recycled into steel products such as steel plate, and aluminum cans are recycled into automobile parts. The pens that we all use every day are made from recycled food trays and PET bottles. As you can see, we recycle all kinds of things.
