I Dekemaba 2021, ua hoʻopuka pū ka State Forestry and Grassland Administration, National Development and Reform Commission a me 10 mau keʻena ʻē aʻe i ka "Opinions on Accelerating the Innovation and Development of the Bamboo Industry". Ua hoʻokumu nā wahi like ʻole i nā kulekele kākoʻo e hāʻawi i ke kākoʻo kulekele ikaika no ka hoʻolaha ʻana i ka hoʻomohala kiʻekiʻe o ka ʻoihana ʻohe, me ka pulp bamboo a me ka ʻoihana pepa. ʻO koʻu ʻāina ka nui o ka pulp ohe a me nā wahi hana pepa ma Sichuan, Guizhou, Chongqing, Guangxi, Fujian a me Yunnan. Ma waena o lākou, ʻo Sichuan ka ʻāpana ʻohe nui loa a me ka ʻāina hana pepa i koʻu ʻāina. I kēia mau makahiki i hala iho nei, ua hoʻomohala ikaika ʻo Sichuan Province i kahi hui pulp a me ka ʻoihana pepa o ka "bamboo-pulp-paper-processing-sales", i hana i kahi hōʻailona koʻikoʻi o ka pepa hale pulp ʻohe, a ua hoʻololi i nā pono o nā kumu waiwai ʻōmaʻomaʻo i ka ulu ʻana o ka ʻoihana. nā pōmaikaʻi, ka loaʻa ʻana o nā hopena kupaianaha. Ma muli o ka waiwai o ka ʻohe waiwai, ua mahi ʻo Sichuan i nā ʻano ulu lāʻau ʻohe kiʻekiʻe, hoʻomaikaʻi i ka maikaʻi o nā kumu ulu lāʻau ʻohe, kanu i nā ululāʻau ʻohe ma nā pali ʻoi aku ma mua o 25 degere a me nā ʻāina mahiʻai kumu ʻole me nā pali o 15 a 25 degere i ka wai nui. nā kumu i kūpono i ke kulekele, hoʻolaha ʻepekema i ka hoʻokele ʻana i nā ʻano ʻekolu o nā ululāʻau ʻohe, hoʻohui i ka hoʻomohala ʻana i nā ululāʻau lāʻau ʻohe a me nā ululāʻau kaiaola, a hoʻoikaika i nā ʻano hana uku a me ke kālā. Ua hoʻonui mau ʻia nā waihona ʻohe. I ka makahiki 2022, ua ʻoi aku ka nui o ka ululāʻau ʻohe ma ka ʻāina ma mua o 18 miliona mu, e hāʻawi ana i ka nui o nā kumulāʻau ʻohe kiʻekiʻe kiʻekiʻe no ka pulping ʻohe a me ka hana ʻana i ka pepa, ʻoi aku ka nui o ka pulp bamboo natural color home pepa. I mea e hōʻoiaʻiʻo ai i ka maikaʻi o ka pepa ʻohana pulp ʻohe a hoʻomaikaʻi i ka ʻike maka o ka pepa kala maoli ma ka home a ma waho, ua noi ka Sichuan Paper Industry Association i ke Keʻena Trademark o ka State Intellectual Property Office no ke kākau inoa ʻana i ka "Bamboo Pulp Paper. " hōʻailona kālepa hui. Mai ka paio lima hoʻokahi i hala a hiki i ka hoʻomohala kikowaena a me ka nui o kēia manawa, ʻo ka paʻa ʻana no ka hui pumehana a lanakila-lanakila ua lilo ia i mea maikaʻi o ka hoʻomohala ʻana o Sichuan Paper. I ka makahiki 2021, aia he 13 mau ʻoihana pulping ʻohe ma luna o ka nui i koho ʻia ma ka ʻāina ʻo Sichuan, me ka hoʻopuka ʻana o ka pulp ʻohe o 1.2731 miliona tons, he piʻi ʻana o ka makahiki he 7.62%, helu ʻia no 67.13% o ka hoʻopuka ʻana o ka pulp ʻohe kumu, o ka. i hoʻohana ʻia ma kahi o 80% e hana i ka pepa hale; aia he 58 mau ʻoihana pepa waihona pepa hale me ka puka makahiki he 1.256 miliona tona; aia he 248 mau ʻoihana hana pepa ʻohana pulp pulp me ka puka makahiki o 1.308 miliona mau tona. Ua kūʻai ʻia ʻo 40% o ka pepa hale pulp o ka ʻohe maoli i hana ʻia ma ka ʻāina, a kūʻai ʻia ʻo 60% ma waho o ka mokuʻāina a ma waho ma o nā kahua kūʻai e-commerce a me ka hoʻolālā aupuni "Belt and Road". Nānā ka honua iā Kina no ka pulp ʻohe, a nānā ʻo Kina iā Sichuan no ka pulp ʻohe. Ua hele a puni ka brand "Bamboo pulp paper" Sichuan.

ʻO koʻu ʻāina ka mea hana nui loa o ka ʻohe pulp / ʻohe dissolving pulp, me 12 mau laina hana pulp kemika o kēia wā me ka mana hana makahiki ʻoi aku ma mua o 100,000 tons, ka nui o ka mana hana o 2.2 miliona tons, nona ka 600,000 tons he ʻohe ʻohe. pulp. ʻO Fang Guigan, ka mea noiʻi a me ka luna kauka kauka ma ka Institute of Forest Products Chemical Industry o ka Chinese Academy of Forestry, ua hoʻopaʻa lōʻihi i ka noiʻi a me ka hoʻomohala ʻana i nā ʻenehana nui a me nā lako no ka ʻoihana pulping maʻemaʻe kiʻekiʻe o koʻu ʻāina. Ua ʻōlelo ʻo ia, ma hope o ka hoʻoikaika pū ʻana o ka ʻoihana, ke kula a me ka noiʻi, ua haki nā mea noiʻi i nā ʻenehana koʻikoʻi o ka pulp bamboo / dissolving pulp production, a ua hoʻohana nui ʻia nā ʻenehana kuke a me ka bleaching a me nā mea hana i ka hana ʻana i ka pulp kemikala ʻohe. Ma o ka hoʻololi ʻana a me ka hoʻohana ʻana i nā hopena noiʻi ʻepekema a me ka ʻenehana e like me "New Technologies for Efficient Bamboo Pulping and Papermaking" mai ka "Twelfth Five-Year Plan", ua hoʻoponopono mua koʻu ʻāina i ka pilikia o N a me P koena paʻakai ma ke kaʻina hana ka wehe ʻana i ka waiʻona ʻeleʻele silika a me ka mālama ʻana i waho. I ka manawa like, ua holomua ka holomua ma ka hoʻonui ʻana i ka palena keʻokeʻo o ka bleaching pulp bleaching kiʻekiʻe. Ma lalo o ke kūlana o ka hoʻokele waiwai bleaching dosage, ua hoʻonui ke keʻokeʻo o ka pulp kiʻekiʻe o ka ʻohe mai lalo o 65% a ʻoi aku ma mua o 70%. I kēia manawa, ke hana nei nā mea noiʻi e wāwahi i nā bottlenecks ʻenehana e like me ka hoʻohana ʻana i ka ikehu kiʻekiʻe a me ka haʻahaʻa haʻahaʻa i ke kaʻina hana o ka pulp ʻohe, a hoʻāʻo e hana i nā pono kumukūʻai i ka hana pulp ʻohe a hoʻomaikaʻi i ka hoʻokūkū mākeke honua o ka pulp ʻohe.
