Cellulose nubutunzi bwinshi kama bushobora kuvugururwa kwisi. Iva mu bimera byo ku isi no munsi y’amazi kandi ni igice cyingenzi cyurukuta rwibimera. Usibye umubare muto wa bagiteri yinyamaswa n’ibinyabuzima byo mu nyanja, selile ibaho cyane cyane mu bimera bibisi. Binyuze kuri fotosintezeza, ibimera birashobora guhuza selile ya 155Gt ku mwaka, muri byo 150Mt ikomoka ku bimera byo hejuru; selile pulp selulose ni nka 10Mt; ipamba selile 12Mt; imiti (urwego) 7Mt ya selile, mugihe ibiti byinshi (hafi 500Mt ya selile) biracyakoreshwa nka lisansi cyangwa igitambaro.
Cellulose karemano iratandukanye mubyera. Ipamba ni fibre yibihingwa bifite selile nyinshi muri kamere, kandi selile yayo isanzwe iri hejuru ya 95%. Ipamba ndende ikoreshwa muburyo bwo gukora imyenda. Fibre ngufi yitwa Linter pulp, nigikoresho cyingenzi cyumusaruro winganda zikomoka kuri selile.
