Mupumburu webamboo rudzi rwemupumburu wakagadzirwa nezvinhu zvebamboo zvakaita semoso bamboo, nanzhu, uye cizhu. Unowanzo gadzirwa uchishandisa nzira dzakadai sesulfate necaustic soda. Vamwe vanoshandisawo lime kusveta mupumburu webamboo muchikamu che semi clinker mushure mekubvisa greening. Maumbirwo efaibha nehurefu zviri pakati pemafaibha ehuni nehuswa. Zviri nyore kuisa glue, mupumburu webamboo ifaibha yepakati ine hurefu hwakanaka uye yakapfava. Ukobvu uye kuramba kubvaruka kwemupumburu kwakanyanya, asi simba rekuputika uye simba rekudhonza rakaderera. Ine simba rekugadzira rakawanda.
Muna Zvita 2021, madhipatimendi gumi anosanganisira State Forestry and Grassland Administration pamwe neNational Development and Reform Commission vakaburitsa pamwe chete "Mazano Ekukurumidzisa Kuvandudzwa Kweindasitiri Yemabamboo". Matunhu akasiyana-siyana akagadzirawo marongero anotsigira kuti kukurumidzise kutsvagisa nekuvandudza matekinoroji matsva uye maitiro ekuchengetedza zvakatipoteredza uye nharaunda mukugadzira mapepa emabamboo, vachipa rutsigiro rwakasimba rwekusimudzira kukura kweindasitiri yemabamboo, kusanganisira indasitiri yekugadzira mapepa emabamboo.
Kubva pamaonero emaindasitiri, zvinhu zvikuru zvekugadzira pulp yebamboo zvinosanganisira bamboo dzakadai semoso, nanzhu, uye cizhu; Kuderera kwe pulp yebamboo kunosanganisira mabhizinesi akasiyana-siyana ekugadzira mapepa, uye bepa rinogadzirwa rinowanzova rakasimba uye rine "ruzha". Bepa rakacheneswa rinoshandiswa kugadzira bepa rekudhinda re offset, bepa rekunyora, nemamwe mapepa emhando yepamusoro, nepo bepa risina kucheneswa rinogona kushandiswa kugadzira bepa rekurongedza, nezvimwewo. China ndeimwe yenyika dzine zviwanikwa zvakapfuma zvemiti yebamboo pasi rose, nenzvimbo yemasango ebamboo ichitora chikamu chinodarika 1/4 chenzvimbo yese yemasango ebamboo pasi rose uye kugadzirwa kwebamboo kuchitora chikamu chimwe muzvitatu chekugadzirwa kwepasi rose. Muna 2021, kugadzirwa kwebamboo muChina kwaive mabhiriyoni 3.256, kuwedzera kwe0.4% kupfuura gore rapfuura.
Senyika ine kugadzirwa kukuru kwemupumburu wembanje pasi rose, China ine mitsetse gumi nembiri yekugadzira pulp yemakemikari emubanje ine kugona kugadzira matani anopfuura chiuru chimwe pagore, ine kugona kugadzira matani mamiriyoni maviri nehafu, kusanganisira matani mazana matanhatu emakumi mashanu emupumburu unonyungudika wemubanje. Shanduro itsva yemutemo wekudzora mapurasitiki inotaura nezvehuwandu hwekudzora mapurasitiki uye kusarudzwa kwezvimwe zvigadzirwa, zvichiunza mikana mitsva kumabhizinesi ekugadzira pulp yembanje. Muna 2022, kugadzirwa kwemupumburu wembanje muChina kwaive matani mamiriyoni maviri nemazana mana nematanhatu, kuwedzera kwegore negore kwe1.7%.
Sichuan Petrochemical Yashi Paper Industry Co., Ltd. ikambani iri pasi peChina Petrochemical Group. Ndiyo kambani hombe mukugadzira mapepa emhando ye bamboo pulp muChina, ine mhando dzakasiyana-siyana. Ndiyo kambani inonyanya kuratidza mapepa emhando ye bamboo fiber anoshandiswa zuva nezuva muChina. Ikambani yenyika yepamusoro-soro inonyanya kuongorora nekugadzira, kugadzira, uye kutengesa mapepa emhando yepamusoro uye imwe yemakambani gumi epamusoro epepa emhando yepamusoro muSichuan Province. Kugadzirwa kwayo kwezvigadzirwa, huwandu hwekutengesa, uye mugove wemusika zvakave zvekutanga muindasitiri yekugadzira mapepa emhando ye bamboo muSichuan Province kwemakore matanhatu akatevedzana, uye zvakave zvekutanga muindasitiri yenyika ye bamboo pulp yemhando ye bamboo kwemakore mana akatevedzana.
