Bamboo zamkati ndi mtundu wa zamkati zopangidwa kuchokera ku nsungwi monga moso nsungwi, nanzhu, ndi cizhu. Amapangidwa kawirikawiri pogwiritsa ntchito njira monga sulphate ndi caustic soda. Ena amagwiritsanso ntchito laimu kuti azitola nsungwi zanthete mu semi clinker zitatha kubiriwira. Utali wa ulusi ndi utali uli pakati pa ulusi wa matabwa ndi udzu. Chosavuta kugwiritsa ntchito guluu, nsungwi zamkati ndi zamkati zazitali za ulusi zomwe zimakhala zabwino komanso zofewa. Makulidwe ndi kukana kung'ambika kwa zamkati ndizokwera, koma mphamvu yophulika ndi mphamvu zolimba ndizochepa. Ali ndi mphamvu zamakina apamwamba.
Mu Disembala 2021, madipatimenti khumi kuphatikiza State Forestry and Grassland Administration ndi National Development and Reform Commission mogwirizana adapereka "Maganizo pa Kupititsa patsogolo Chitukuko Chatsopano cha Makampani a Bamboo". Madera osiyanasiyana apanganso mfundo zothandizira kuti apititse patsogolo kafukufuku ndi chitukuko cha matekinoloje atsopano ndi njira zotetezera zachilengedwe ndi zachilengedwe pakupanga mapepala a nsungwi, kupereka chithandizo champhamvu cholimbikitsa chitukuko chapamwamba cha makampani a nsungwi, kuphatikizapo malonda a mapepala a nsungwi.
Kuchokera pakuwona kwa unyolo wa mafakitale, zinthu zazikulu zopangira nsungwi ndi nsungwi monga moso, nanzhu, ndi cizhu; Pansi pa nsungwi ya nsungwi pamakhala makampani osiyanasiyana opanga mapepala, ndipo mapepala omwe amapangidwa nthawi zambiri amakhala olimba ndipo ali ndi "mawu omveka". Pepala lopukutidwa limagwiritsidwa ntchito popanga mapepala osindikizira a offset, mapepala olembera, ndi mapepala ena apamwamba, pomwe mapepala osapukutidwa angagwiritsidwe ntchito popanga mapepala opaka, ndi zina zotero. China ndi imodzi mwa mayiko omwe ali ndi zomera zolemera kwambiri za nsungwi padziko lonse lapansi, ndipo nkhalango ya nsungwi imasunga zoposa 1/4 ya nkhalango yonse ya nsungwi padziko lonse lapansi ndipo kupanga nsungwi kumasunga 1/3 ya kupanga konse padziko lonse lapansi. Mu 2021, kupanga nsungwi ku China kunali 3.256 biliyoni, kuwonjezeka kwa 0.4% kuposa chaka chatha.
Monga dziko ndi yaikulu nsungwi zamkati kupanga padziko lapansi, China ali 12 masiku nsungwi mankhwala zamkati kupanga mizere ndi mphamvu pachaka kupanga matani pa 100000, ndi okwana kupanga mphamvu matani 2.2 miliyoni, kuphatikizapo 600000 matani nsungwi sungunuka zamkati kupanga mphamvu. Mtundu watsopano wa malamulo oletsa pulasitiki umanena za kuletsa kwa pulasitiki ndi kusankha kwazinthu zina, kubweretsa mwayi watsopano wamabizinesi opanga mapepala a bamboo. Mu 2022, kupanga nsungwi ku China kunali matani 2.46 miliyoni, kuwonjezeka kwa chaka ndi 1.7%.
Sichuan Petrochemical Yashi Paper Industry Co., Ltd. ndi kampani yocheperako ya China Petrochemical Group. Ndi kampani yayikulu kwambiri yopanga mapepala achilengedwe a nsungwi ku China, yokhala ndi mitundu yosiyanasiyana komanso mitundu yosiyanasiyana. Ndi kampani yabwino kwambiri yoyimira mapepala achilengedwe a nsungwi 100% omwe amagwiritsidwa ntchito tsiku ndi tsiku ku China. Ndi kampani yapamwamba kwambiri yapadziko lonse yomwe imayang'anira kafukufuku ndi chitukuko, kupanga, ndi kugulitsa mapepala apamwamba apakhomo komanso imodzi mwa mabizinesi khumi apamwamba kwambiri a mapepala apakhomo ku Sichuan Province. Kupanga kwake zinthu zomalizidwa, kuchuluka kwa malonda, ndi gawo la msika kwakhala pamalo oyamba mumakampani opanga mapepala apakhomo ku Sichuan Province kwa zaka zisanu ndi chimodzi motsatizana, ndipo yakhala pamalo oyamba mumakampani opanga mapepala achilengedwe a nsungwi kwa zaka zinayi motsatizana.
