To show that paper can be made using many different materials other than wood, including some that you can find at home.
Paper is made from cellulose, which is in plant fibers.
The cellulose is made by cutting down trees, grinding them up, and dumping the woodpulp in acid. Paper can also be recycled from other paper. Old paper is sent to factories, where it is shredded and mashed into pulp, which is then turned back into paper. Recycling uses cellulose over and over again, which saves trees from being cut down. Recycling about 54 kg of newspaper will save one tree.
