Izimboni ze-Pulp kanye nePhepha zihlukaniswe izingxenye ezimbili: i-pulping kanye nokwenza iphepha. Inqubo ye-pulping inqubo lapho impahla ecebile ngefayibha efana nempahla ilungiselelwa, iphekwe, iwashwe, ifakwe i-bleaching, nokunye okunjalo ukuze kwakheke i-pulp engasetshenziselwa ukwenza iphepha. Enkambweni yokwenza iphepha, i-slurry ethunyelwe kusukela emnyangweni we-pulping ingaphansi kwenqubo yokuxuba, ukugeleza, ukucindezela, ukomisa, ukugoqa, njll ukukhiqiza iphepha eliqediwe. Ngaphezu kwalokho, iyunithi yokutakula i-alkali iphinda ithole uketshezi lwe-alkali otshwaleni olumnyama olukhishwe ngemva kokushaywa ukuze luphinde lusetshenziswe. Umnyango wokuhlanza amanzi angcolile uphatha amanzi angcolile ngemva kokwenza iphepha ukuze uhlangabezane namazinga afanele kazwelonke wokukhishwa kwegesi. Izinqubo ezihlukahlukene zokukhiqizwa kwephepha okungenhla zibalulekile ekulawuleni i-valve elawulayo.
