Ifu y'imigano ni ubwoko bw'ifu ikozwe mu bikoresho by'imigano nka moso bamboo, nanzhu, na cizhu. Ikunze gukorwa hakoreshejwe uburyo nka sulfate na caustic soda. Hari kandi bakoresha indimu mu gusya imigano yoroshye ikayihindura imiraba nyuma yo kuyikuraho icyatsi. Imiterere n'uburebure bya fibre biri hagati y'imirongo y'ibiti n'ibyatsi. Kole yoroshye kuyishyiraho, ni fu y'imigano ifite uburebure buringaniye kandi yoroshye. Ubunini n'ubudahangarwa bw'ifu y'imigano ni byinshi, ariko imbaraga zo gucika n'imbaraga zo gukurura ni nke. Ifite imbaraga nyinshi za mekanike.
Mu Ukuboza 2021, amashami icumi arimo Ubuyobozi bw'Amashyamba n'Ubwatsi bwa Leta na Komisiyo y'Igihugu Ishinzwe Iterambere n'Ivugurura byashyize ahagaragara ku bufatanye "Ibitekerezo byo Kwihutisha Iterambere Rishya ry'Inganda z'Imigano". Uturere dutandukanye twashyizeho kandi politiki zishyigikira kwihutisha ubushakashatsi n'iterambere ry'ikoranabuhanga rishya n'inzira zo kurengera ibidukikije n'ibidukikije mu gukora impapuro z'imigano, bitanga inkunga ikomeye ya politiki yo guteza imbere iterambere ry'inganda z'imigano, harimo n'inganda zikora impapuro z'imigano.
Ukurikije uruhererekane rw'inganda, ibikoresho by'ingenzi by'ibanze bya pulp ya bamboo ni imigano nka moso, nanzhu, na cizhu; Igice cya nyuma cya pulp ya bamboo gikubiyemo ibigo bitandukanye bikora impapuro, kandi impapuro zikorwa muri rusange ziba zikomeye kandi zifite "urusaku". Impapuro za bleached zikoreshwa mu gukora impapuro za offset icapiro, impapuro zo kwandika, n'izindi mpapuro z'umuco zigezweho, mu gihe impapuro zitarasheshwe zishobora gukoreshwa mu gukora impapuro zo gupakira, nibindi. Ubushinwa ni kimwe mu bihugu bifite umutungo ukize cyane w'ibimera bya bamboo ku isi, aho agace k'ishyamba rya bamboo gafite arenga 1/4 cy'ubuso bwose bw'ishyamba rya bamboo ku isi n'umusaruro wa bamboo ugize 1/3 cy'umusaruro wose ku isi. Mu 2021, umusaruro w'imigano mu Bushinwa wari miliyari 3.256, ubwiyongere bwa 0.4% ugereranyije n'umwaka ushize.
Nk’igihugu gifite umusaruro munini w’ibikomoka ku bimera bya bamboo ku isi, Ubushinwa bufite imirongo 12 igezweho ikora ibimera bya bamboo ifite ubushobozi bwo gukora toni zisaga 100000 buri mwaka, ifite ubushobozi bwo gukora toni miliyoni 2.2, harimo toni 6000000 z’ibimera bishongeshwa mu bimera bya bamboo. Verisiyo nshya y’itegeko ryo kugabanya ibimera bya bamboo ivuga ko hagomba kugabanywa ibimera bya bamboo no guhitamo ibindi bicuruzwa, bigatanga amahirwe mashya ku bigo bikora impapuro za bamboo. Mu 2022, umusaruro w’ibimera bya bamboo mu Bushinwa wari toni miliyoni 2.46, ubwiyongere bw’umwaka ku kigero cya 1.7%.
Sichuan Petrochemical Yashi Paper Industry Co., Ltd. ni ishami rya China Petrochemical Group. Ni ikigo kinini gitanga umusaruro mu nganda z’impapuro karemano za bamboo pulp mu Bushinwa, gifite ubwoko bwuzuye bw’ibipimo n’ubwoko. Ni kandi ikigo cy’indashyikirwa gihagarariye impapuro karemano za bamboo 100% zikoreshwa buri munsi mu Bushinwa. Ni ikigo cy’igihugu gikoresha ikoranabuhanga rihanitse cyihariye mu bushakashatsi no guteza imbere, gutunganya no kugurisha impapuro zigezweho zo mu ngo ndetse kikaba kimwe mu bigo icumi bya mbere by’impapuro zo mu ngo mu Ntara ya Sichuan. Umusaruro wayo urangiye, ingano y’ibicuruzwa byagurishijwe, n’isoko byaje ku mwanya wa mbere mu nganda zitunganya impapuro zo mu ngo mu Ntara ya Sichuan mu myaka itandatu yikurikiranya, kandi byaje ku mwanya wa mbere mu nganda z’impapuro karemano za bamboo pulp mu gihugu mu myaka ine yikurikiranya.
