I-Cellulose iyinsiza ye-organic evuselelekayo egcwele kakhulu emhlabeni. Ivela ezitshalweni eziluhlaza zasemhlabeni kanye nezangaphansi kwamanzi futhi iyisakhi esiyinhloko sezindonga zamaseli ezitshalo. Ngaphandle kwenani elincane lamabhaktheriya ezilwane nezinto eziphila ngaphansi kolwandle, i-cellulose itholakala kakhulu ezitshalweni eziluhlaza. Nge-photosynthesis, izitshalo zingahlanganisa i-cellulose engu-155Gt ngonyaka, lapho i-150Mt ivela ezitshalweni eziphakeme; i-wood pulp cellulose imayelana ne-10Mt; ukotini cellulose 12Mt; amakhemikhali (ibanga) 7Mt we-cellulose, kuyilapho inani elikhulu lezinkuni (cishe i-500Mt ye-cellulose) lisasetshenziswa njengamafutha noma indwangu.
I-cellulose yemvelo iyahlukahluka ngobumsulwa. Ukotini uyifayibha yezitshalo enokuqukethwe okuphezulu kakhulu kwe-cellulose emvelweni, futhi okuqukethwe kwawo kwe-cellulose kuvame ukuba ngaphezu kwama-95%. Izisekelo ezinde zikakotini zisetshenziswa ngokwesiko ekukhiqizeni izindwangu. I-fiber emfushane ibizwa ngokuthi i-Linter pulp, okuyingxenye ebalulekile yokukhiqizwa kwezimboni kokuphuma kwe-cellulose.
