Imigano ni ubwoko bwimbuto ikozwe mubikoresho by'imigano nka moso imigano, nanzhu, na cizhu. Bikunze gukorwa hakoreshejwe uburyo nka sulfate na soda ya caustic. Bamwe bakoresha kandi lime kugirango batoragure imigano yoroheje muri clinker ya nyuma nyuma yicyatsi. Fibre morphologie nuburebure buri hagati yibi biti nibyatsi. Biroroshye gushira kole, imigano ni fibre iringaniye ya fibre nziza kandi yoroshye. Umubyimba n'amarira birwanya pulp ni muremure, ariko imbaraga ziturika n'imbaraga zingana ni nke. Ifite imbaraga zo gukanika.
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 ryu Bushinwa Petrochemical Group. Nicyo kigo kinini gitanga umusaruro mubikorwa byimigano yimpapuro zisanzwe mubushinwa, hamwe nibisobanuro bitandukanye. Nicyo kigo cyiza cyane gihagarariwe 100% imigano ya fibre fibre isanzwe ikoreshwa mubushinwa. Ni ikigo cy’igihugu cy’ikoranabuhanga gifite ubuhanga mu bushakashatsi no guteza imbere, gukora, no kugurisha impapuro zo mu rugo zo mu rwego rwo hejuru kandi ni kimwe mu bigo icumi bya mbere by’impapuro zo mu rugo mu Ntara ya Sichuan. Umusaruro wacyo urangiye, ibicuruzwa byagurishijwe, hamwe n’umugabane ku isoko byashyizwe ku mwanya wa mbere mu nganda zitunganya impapuro zo mu rugo mu Ntara ya Sichuan mu myaka itandatu yikurikiranya, kandi biza ku mwanya wa mbere mu nganda z’imigano y’impapuro zisanzwe mu myaka ine ikurikiranye.
