From the point of view of recycling, paper has two advantages over minerals and 0- (n) oil. In that firstly it comes from a resource which is 1- (adj) sustainable and secondly it is less threatening to our environment when we throw it away because it is 2- (adj) biodegradable. Although Australia’s record in the re-use of waste paper is good, it is still necessary to use a combination of recycled fibre and 3- (n) virgin fibre to make new paper. The paper industry has contributed positively and people have also been encouraged by 4- (n) government to collect their waste on a regular basis. One major difficulty is the removal of ink from used paper but 5- (n) advances are being made in this area. However, we need to learn to accept paper which is generally of a lower 6- (n) quality than before and to sort our waste paper by removing 7- (n) contaminants before discarding it for collection.

Paper is named for papyrus, a reed like plant used by ancient Egyptians as writing material more than 5000 years ago. The Chinese invented the paper that we use 2000 years ago.
A piece of paper is really made up of tiny fibers, unlike a piece of material. The fibers used in paper, however, are plant fibers, and there are millions of them in one sheet. In addition to the plant fiber, dyes and additives such as resin may be used. Dyes can make the paper different colors; resin may add weight and texture.
Where do these fibers come from ? The majority of paper is made from the plant fiber that comes from trees. Millions are cut down, but new trees are planted in their place. Paper may be also made from things like old rags or pieces of cloth. Wastepaper, paper that has been made and used, can be turned into recycled paper. This recycling process saves forest, energy and reduces air and water pollution.
