In order to save resources, usually we print on both sides of the paper. However, even so, one piece of paper can be used at most twice. Is there any way to recycle the paper? Recently, the chemist from University of California, Riverside, invented the glass paper which can be recycled and printed over and over again with a particular printer.
This kind of paper is made of glass and plastic film, the words printed on which can be removed easily by heating. The words printed on this kind of paper, like the meeting schedule, can be kept for around three days and can be removed in ten minutes at 115 degrees centigrade if it is to be reused.
The researchers say that the letters printed on this glass paper is very clear and easy to read for three days, which is suitable for the documents which do not need to be filed. Now, the researchers are doing further research on the glass paper aiming to make the glass paper that can be used over one hundred times without spoiling the quality.
