Ma ke ʻano o ka lohi o ka noi no ka pepa moʻomeheu, hiki i ka ulu ʻana o ka noi no ka pepa hale ke hoʻoulu maikaʻi i ka ʻai ʻana i ka mākeke pulp lāʻau.Ma ka hoʻohālikelike hoʻohālikelike, ʻo ka hoʻohana ʻana o ka pepa hale i kēlā me kēia kanaka ma koʻu ʻāina he 6kg / kanaka-makahiki wale nō, ʻoi aku ka haʻahaʻa ma mua o nā ʻāina kūkulu.I ka pōʻaiapili o ka lohi o ka noi no ka pepa moʻomeheu i koʻu ʻāina, ua manaʻo ʻia ka noi no ka pepa hale e lilo i mea hoʻokele ulu hou no ka noi pulp.
Wahi a ka ʻike kuʻuna, i nā mahina ʻehiku mua o kēia makahiki, ua lawe mai ke awa ʻo Manzhouli i 299,000 tons o ka pulp, kahi piʻi o 11.6% i kēlā me kēia makahiki;ʻo ka waiwai he 1.36 biliona, he piʻi o 43.8% i kēlā me kēia makahiki.He mea pono ke olelo aku i ka mahina o Iulai o keia makahiki, o ka pulp i laweia mai ma ke awa o Manzhouli he 34,000 tons, he 8% ka nui o ka makahiki;ʻO ka waiwai he 190 miliona, he piʻi o 63.5% makahiki ma ka makahiki.I nā mahina ʻehiku mua o kēia makahiki, ʻo ke awa nui loa o Kina - ke awa ʻo Manzhouli, ʻoi aku ka nui o ka waiwai o ka pulp ma mua o 1.3 biliona.Pili kēia i ka piʻi nui ʻana o ka mākeke pulp lāʻau kūloko i ka hapa mua o kēia makahiki, kahi i hoʻonui ai i ka lawe ʻana mai.
I loko o ka lāʻau mua a me ka pulp latewood, ʻokoʻa ka ratio o ka lāʻau mua a me ka lāʻau hope, a ʻokoʻa hoʻi ka maikaʻi o ka pulping ke hoʻohana ʻia nā ʻano kuʻi like no ka hahau ʻana.He lōʻihi ka lāʻau hope, mānoanoa a paʻakikī ka paia o ke kelepona, a ʻaʻole hiki ke pohō ka paia hānau.I ka wā o ka hahau ʻana, ʻoki maʻalahi nā fiber, a paʻakikī ke komo i ka wai a pehu a lilo i fibrillated.
ʻO Kina kekahi o nā mea kūʻai nui loa o ka pulp lāʻau, a ʻaʻole hiki iā ia ke hoʻokō pono i ka pono ponoʻī o ka pulp maka kumu ma muli o ka nele o nā kumu ulu lāʻau.ʻO ka pulp lāʻau e hilinaʻi nui ʻia i ka lawe ʻia mai.I ka makahiki 2020, he 63.2% ka lawe ʻana mai o ka pulp lāʻau, ma lalo o 1.5 pakeneka mai 2019.
