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. Maonekedwe a ulusi ndi kutalika kwake zili pakati pa ulusi wamatabwa 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 kuphulika kwamphamvu 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 nsungwi zamkati. .
Kutengera momwe mafakitale amagwirira ntchito, zida zopangira nsungwi zakumtunda ndi nsungwi monga moso, nanzhu, ndi cizhu; Kutsikira kwa nsungwi kumaphatikizapo mabizinesi osiyanasiyana opangira mapepala, ndipo pepala lopangidwa nthawi zambiri limakhala lolimba ndipo limakhala ndi "phokoso". Mapepala owukidwa amagwiritsidwa ntchito popanga mapepala osindikizira a offset, mapepala otayipa, ndi mapepala ena apamwamba kwambiri a chikhalidwe, pamene mapepala osatsekedwa amatha kugwiritsidwa ntchito popanga mapepala, ndi zina zotero. Dera la nsungwi lomwe lili ndi nkhalango yopitilira 1/4 ya nkhalango zonse za nsungwi padziko lonse lapansi komanso kupanga nsungwi zomwe zimatengera 1/3 yazinthu zonse padziko lonse lapansi. Mu 2021, kupanga nsungwi ku China kunali 3.256 biliyoni, kuwonjezeka kwa 0.4% kuposa chaka chatha.
Monga dziko ndi waukulu nsungwi zamkati kupanga padziko lonse, China ali 12 masiku nsungwi mankhwala zamkati kupanga mizere ndi mphamvu yopanga pachaka matani oposa 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 ya China Petrochemical Group. Ndilo bizinesi yayikulu kwambiri yopangira nsungwi zamkati yamapepala achilengedwe ku China, yokhala ndi mawonekedwe ndi mitundu yambiri. Ndilonso kampani yodziwika bwino kwambiri ya 100% yamapepala achilengedwe a nsungwi omwe amagwiritsidwa ntchito tsiku lililonse ku China. Ndilo bizinesi yapamwamba kwambiri padziko lonse lapansi yomwe imagwira ntchito pa kafukufuku ndi chitukuko, kupanga, ndi malonda a mapepala apanyumba apamwamba kwambiri komanso amodzi mwa makampani khumi apamwamba a mapepala apanyumba m'chigawo cha Sichuan. Kapangidwe kake komalizidwa, kuchuluka kwa malonda, ndi gawo la msika zakhala pamalo oyamba pamakampani opanga mapepala apanyumba m'chigawo cha Sichuan kwa zaka zisanu ndi chimodzi zotsatizana, ndipo adakhala woyamba pamakampani opanga mapepala achilengedwe a nsungwi kwa zaka zinayi zotsatizana.
