Paper making from the sources of trees and forests is always a factor in the elimination of natural resources .On the other hand, the production of paper from stone also has other problems. Therefore, due to these problems, paper making from animal waste was considered. In fact, in this plan, using animal waste in making paper is for example, the waste of cattle, horses, cows etc., to make paper to use in writing and transcription. Since paper is in domestic demand in every country, it will also have a suitable market for exports.
