Makampani opanga ma pulp ndi mapepala amagawidwa m'magawo awiri: pulping ndi kupanga mapepala. Njira yopangira ma pulping ndi njira yomwe zinthu zokhala ndi ulusi wambiri monga zinthu zimakonzedwa, kuphikidwa, kutsukidwa, kutsukidwa, ndi zina zotero kuti apange ma pulp omwe angagwiritsidwe ntchito popanga mapepala. Pakupanga mapepala, matope omwe amatumizidwa kuchokera ku dipatimenti yopangira ma pulping amachitidwa njira yosakaniza, kuyenda, kukanikiza, kuumitsa, kupota, ndi zina zotero kuti apange pepala lomalizidwa. Kuphatikiza apo, chipangizo chobwezeretsa alkali chimatenga madzi a alkali mu mowa wakuda womwe umatulutsidwa pambuyo pochotsa ma pulping kuti ugwiritsidwenso ntchito. Dipatimenti yokonza madzi otayira imasamalira madzi otayira pambuyo popanga mapepala kuti akwaniritse miyezo yoyenera ya dziko lonse yotulutsa mpweya. Njira zosiyanasiyana zopangira mapepala zomwe zili pamwambapa ndizofunikira kwambiri pakuwongolera valavu yowongolera.
