Mu buhinga bushasha bw’ubuhinga bwa bonsai kuva mu 2023 gushika mu 2024, gukoresha urusenga rw’itongo rwo mu murima rwa PVC-rwabaye ikintu gihambaye, n’ivyo bivako, umugozi w’aluminium ushizweko PVC{3}}, bituma ubuhinga bwo gutera amabonsai bugenda neza cane nk’ubw’umugozi wa Pyraananthaca. Igerageza ryakozwe n’ishirahamwe ry’i Guangzhou Bonsai ryerekanye ko ugereranije n’urutsinga rwa kera rw’aluminium, urutsinga rwa aluminium rwo mu bwoko bwa PVC-rwirinda gukorana n’icuma n’igishishwa, bigatuma amashami yihuta gukira ku rugero rwa 15%. Ishirahamwe ry’abahinga mu vy’ibiti ryitwa China Bonsai Artists Alliance na ryo nyene risaba ko umuntu akoresha umuti wica ibiherere ku mubiri iyo ariko arakora amawaya n’ico kintu mu kiringo c’imvura, ivyo bikaba bishobora kugabanya igitigiri c’ibikoko bishobora kwanduzwa n’ibiherere ku biti ku bice 60 kw’ijana. Kuyifatanya n'amaporogarama y'ubwenge nka "Bonsai Treasure" kugira ngo yandike ingene ibikorwa bigenda no kwibutsa abakoresha igihe co gukuraho iyo nsinga, bituma ubuhinga bwo gucungera bonsai butera imbere. Ivyerekeye iyo nsinga ya PVC-ipfutse na vyo nyene biragabanywa hakurikijwe ivyo bikenewe: intsinga ifise umurongo ugera kuri 1/3 w’ishami ni yo ikoreshwa ku ntugu nyamukuru, mu gihe intsinga y’iminota 1,5 y’umubiri mutoyi cane ibereye amashami.
Kuva mu mwaka w’2025, ivyerekanwa vy’ugukoresha urusenga rw’itongo rwo mu bwoko bwa PVC-mu buhinzi bwo mu rugo no mu mirima y’ibimera vyarabandanije kwaguka. Ivyiyumviro vyavuzwe kuri Taobao vyerekana ko urusenga rwo kuduga rwo mu bwoko bwa PVC-rubereye ibiterwa bitandukanye vy’imizabibu nk’ibitoke vy’umukara n’ivyamwa vy’umukara, bifasha imizabibu gukura mu buryo buhagaze, bikazigama umwanya, bikongera umuco, kandi bituma ivyamwa bikura neza. Biroroshe kandi gushiramwo; mbere n’abashasha mu vy’uburimyi barashobora kuyishiraho mu minota mikeyi. Ubwo bwoko bw’urusenga burakundwa cane kandi mu mirima y’ibimera yo mu Buraya no muri Amerika. Abarimyi bavuga ko ibuza imbwebwe n’inkwavu kuragira ibiterwa, mu gihe iyo nzira y’urusenga ituma umuntu ashobora guca umwuka n’umuco. Ico gipfukisho c’icatsi kibisi kirafatanya n’ibidukikije. Amatongo amwe amwe akoresha urwo rusenga mbere yarabonye umwimbu mwinshi, kandi ubuzima bwarwo buramba buragabanya umuzigo w’ibidukikije wo gusubirizwa kenshi.
Isoko ry’isi yose ry’urusenga rw’itongo rwo mu bwoko bwa PVC- (harimwo n’urusenga rwo mu murima rwo mu mirongo itandatu rwo mu bwoko bwa PVC-rufitaniye isano n’urwo) rurabandanya kwaguka. Mu mwaka w’2024, ubunini bw’isoko ry’isi yose ry’iki kiciro bwari hafi miliyari 6,83 z’amadolari y’Amerika, kandi bitegerezwa gushika ku madolari y’Amerika miliyari 7,36 mu mwaka w’2025, kandi bitegerezwa kurenga miliyari 11 z’amadolari y’Amerika mu mwaka w’2030, bikaguma bifise iterambere ry’umwaka ry’ibice nka 7,8%. Iterambere ry’ubutunzi riva ahanini mu bihugu bikiri mu nzira y’amajambere. Aziya y’amajepfo y’ubuseruko yabonye 28% umwaka-ku-umwaka w’ibicuruzwa biva hanze mu 2023 kubera imigambi yo kuzigama amazi nk’umugambi wo gucunga uruzi Mekong. Ubuhinde na Vietnam biriko birihutisha guhindura ibikorwa remezo n’uburimyi; Imigambi y’ubwubatsi bw’amabarabara mu Buhindi mu mwaka w’2022 yonyene itegerezwa gutuma habaho ukwiyongera kw’ibice 15 kw’ijana kw’abasaba insenga zo kwikingira. Mu gihe Afirika ihanganye n’ubushobozi budahagije bwo guhingura ibintu mu gihugu no ku rugero rw’ugushingira ku bicuruzwa biva hanze rwo ku rugero rwa 75%, politike z’uburimyi mu bihugu nka Etiyopiya ziriko ziratuma iterambere ry’umwaka ry’ugusaba insenga zo gukingira uburimyi rirenga 8%, bikaba ari vyo bituma haba isoko rishasha ry’iterambere. Hagati aho, ivyipfuzo mu masoko y’i Buraya no muri Amerika biraguma bimeze neza, vyibanda ku bikoresho vy’agaciro kanini -bibungabunga ibidukikije n’ibikoresho vyo gutunganya ahantu.
Ku ruhande rumwe, ugutera imbere kw’ibikorwa ni co kintu nyamukuru gifasha mu guteza imbere ubuhinga bwo gukora amabarabara y’itongo. Kubera ikirere gikomeye cane n’ibidukikije bikomeye mu turere dutandukanye, ibintu bishobora guhangana n’ibihe vyinshi kandi bikomeye cane biriko biraba ivy’agaciro. Ubuhinga bwo gupfuka titanium dioxide ku rugero rwa Nano- buratuma ibintu bimara imyaka irenga 15, ivyo bikaba ari ugutera imbere kw’ibice 40 kw’ijana ku bikoresho vya kera. Ukwemera kwagutse kw’ibintu bibiri -gupfuka (imbere mu gishushe -dip galvanizing + external PVC) bitanga ubushobozi bwo guhangana n’umunyu amasaha arenga 3000 n’ubukomezi bwo gukomera Burengeye canke bungana na 500MPa, bikaba bituma bibereye ahantu hakomeye nk’aho ivyerekeye umunyu mwinshi -ivyo gutera. Ku rundi ruhande, uguhinduka kw’ibidukikije kuriko kurihuta cane. Amategeko y’ishirahamwe ry’ubumwe bw’Uburayi ryerekeye REACH yatumye amashirahamwe akoresha uburyo bwo gukoresha chromium-ubutagiramwo chromium, kandi umugabane w’isoko ry’ivyo bikoresho mu muryango w’ubumwe bw’Uburayi waraduze uva kuri 15% mu 2021 uja kuri 42% mu 2023. y’ibintu vyabo, n’iya mbere . Umugambi wo kwerekana ugusubira gukoresha ibintu bishaje ku rugero rwa 10.000-toni -ugiye gutangura, ukaba uhuye n’intumbero z’isi yose z’ivy’ubuhinga bwa none. Ikindi kandi, ugutohoza kw’ubwenge kuriko kurakorwa; insenga z’ubwenge zikingira zifise ibikoresho bigenzura umubabaro zarageragejwe ku nzira y’igariyamoshi ya Sichuan-Tibet kandi zitegerezwa gukoreshwa buhoro buhoro mu migambi y’uburimyi bw’ibiterwa n’ibikorwa remezo vy’agaciro kanini muri kazoza.
