Uko inganda za PVC zigenda ziyongera mu buryo burambye no mu mikorere myiza, ibikoresho bitanga ubushobozi bwo kubungabunga ibidukikije bya PVC—inyongeramusaruro z'ingenzi zirinda kwangirika k'ubushyuhe mu gihe cyo gutunganya no kongera igihe cyo kubaho kw'ibicuruzwa—byabaye ingenzi mu guhanga udushya no kugenzura amategeko. Muri 2025, ingingo eshatu z'ingenzi ziganirwaho: impinduka yihutirwa ku miti idafite uburozi, iterambere mu ikoranabuhanga rijyanye no kongera gukoreshwa, hamwe n'ingaruka zikomeje kwiyongera z'amategeko agenga ibidukikije ku isi. Dore isesengura ryimbitse ry'iterambere rikomeye cyane.
Imiterere y'ingufu itera irimbuka ry'ibikoresho bitera imbaraga mu byuma bikomeye
Iminsi yo gukoresha icyuma gikozwe muri lead na cadmiumIbintu bishyigikira PVCbibarirwa mu byiciro, kuko amategeko akaze ku isi yose ashishikariza abakora ibintu ku buryo butekanye. Amabwiriza ya REACH ya EU yabaye ingenzi muri iyi mpinduka, aho isuzuma rikomeje ku mugereka wa XVII rigamije gukomeza kugabanya ingano y’ibinyabutabire bya PVC nyuma y’igihe ntarengwa cya 2023. Iri hinduka ryatumye inganda—kuva ku bwubatsi kugeza ku bikoresho by’ubuvuzi—zireka ibintu bisanzwe bigabanya ibyuma bikomeye, biteza ibyago byo kwanduzwa n’ubutaka mu gihe cyo kujugunyamo imyuka ihumanya mu gihe cyo gutwika.
Hirya no hino mu nyanja ya Atalantika, isuzuma ry’ibyago bya EPA rya Amerika ryo mu 2025 kuri phthalate (cyane cyane Diisodecyl Phthalate, DIDP) ryongereye imbaraga ku mutekano w’inyongera, ndetse no ku bice bitanga ubushobozi bwo kubungabunga ibintu mu buryo butaziguye. Nubwo phthalate zikora cyane cyane nk’imashini zitunganya ibintu mu buryo bwa pulasitiki, isuzuma ryazo ry’amategeko ryagize ingaruka nziza, bituma abakora ibikoresho bahitamo ingamba za "formulation nziza" zirimo imiti igabanya uburozi. Izi ngamba zo kugenzura si imbogamizi zo kubahiriza amategeko gusa—zirimo kuvugurura imiyoboro y’ibikoresho, aho 50% by’isoko rya PVC ritangiza ibidukikije ubu riterwa n’uburyo butari ubw’icyuma gikomeye.
Ibitera imbaraga bya Calcium-Zinc Bifata Icyiciro Gikuru
Abayoboye mu gusimbura formulasiyo za heavy metal niibintu bitera imbaraga calcium-zinc (Ca-Zn). Iki gice gifite agaciro ka miliyari 1.34 z'amadolari ku isi mu 2024, biteganijwe ko kizakura ku kigero cya CAGR cya 4.9%, kikagera kuri miliyari 1.89 z'amadolari mu 2032. Igikurura cyabo kiri mu kuringaniza guke: kudahumanya, kudahindagurika cyane mu bushyuhe, no guhuza na PVC zitandukanye—kuva ku madirishya kugeza ku bikoresho by'ubuvuzi.
Aziya na Pasifika ni byo byiganjemo iri zamuka, bingana na 45% by'ubukene ku isi bwa Ca-Zn, bitewe n'umusaruro munini wa PVC mu Bushinwa n'urwego rw'ubwubatsi mu Buhinde rurimo gutera imbere. Hagati aho, iterambere mu ikoranabuhanga ryatanze uruvange rwa Ca-Zn rufite imikorere myiza kandi rwujuje ibisabwa bya REACH mu gihe rwongera imikorere myiza. Ubu buryo bushyigikira ikoreshwa ry'ingenzi nko gupakira ibiryo hamwe n'insinga z'amashanyarazi, aho umutekano no kuramba bidashoboka kuganirwaho.
Cyane cyane,Ibitera imbaraga bya Ca-Znkandi bihuye n'intego z'ubukungu bushingiye ku ruziga. Bitandukanye n'ubundi buryo bushingiye ku ruziga, bugora kongera gukoresha PVC bitewe n'ingaruka z'ubwandu, formulaire zigezweho za Ca-Zn zorohereza kongera gukoresha imashini, bigatuma ibicuruzwa bya PVC nyuma yo kugurwa bikoreshwa mu buryo bushya bwo kuramba nk'imiyoboro n'ibisenge.
Udushya mu mikorere no kongera gukoreshwa
Uretse impungenge z'uburozi, inganda zibanda ku kunoza imikorere y'ibikoresho bigabanya ubushyuhe—cyane cyane ku bikorwa bigoye. Imiterere myiza nka GY-TM-182 irimo gushyiraho ibipimo bishya, itanga ubushobozi bwo gukorera mu mucyo, kurwanya ikirere, no kudahungabana k'ubushyuhe ugereranije n'imitako gakondo y'ibiti bigabanya ubushyuhe. Iyi ntambwe ni ingenzi ku bicuruzwa bya PVC bisaba ubuziranenge, nk'amafilimi yo gushushanya n'ibikoresho by'ubuvuzi, aho ubwiza n'uburambe ari ingenzi.
Ibyuma bigabanya ubushyuhe mu byuma binini, nubwo bihura n’ibibazo by’ibidukikije, bikomeje kugaragara mu nzego zihariye. Bifite agaciro ka miliyoni 885 z’amadolari mu 2025, isoko ry’ibipimo bigabanya ubushyuhe riri kwiyongera ku rugero ruciriritse (3.7% CAGR) bitewe n’ubushyuhe bwabyo budashobora kwiyongera mu modoka no mu nganda. Ariko, abakora ubu barimo gushyira imbere ubwoko bw’ibyuma binini binini kandi bigabanya uburozi, bigaragaza inshingano zagutse z’inganda zo kubungabunga ubusugire.
Icyerekezo kimwe ni iterambere ry’ibikoresho bigabanya ubushyuhe byongerewe ubushobozi bwo kongera gukoreshwa. Uko gahunda zo kongera gukoresha PVC nka Vinyl 2010 na Vinyloop® ziyongera, hari kwiyongera gukenerwa kw’inyongera zitangirika mu bihe byinshi byo kongera gukoreshwa. Ibi byatumye habaho udushya mu buhanga bwo kubungabunga ubushyuhe bubungabunga imiterere ya PVC ndetse na nyuma yo kuyitunganya kenshi—ni ingenzi mu kurangiza umuyoboro mu bukungu buzenguruka.
Udushya dushingiye ku binyabuzima n'udushya dushingiye kuri ESG
Kuramba si ukurandura uburozi gusa—ni ukuvugurura uburyo bwo kubona ibikoresho fatizo. Ibigo bishya bya Ca-Zn bishingiye ku binyabuzima, bikomoka ku bimera bishobora kongera gukoreshwa, birimo kwiyongera, bitanga ubwinshi bwa karuboni nke ugereranyije n’ibindi bikomoka kuri peteroli. Nubwo bikiri bike, ibi bitera imbaraga mu kubungabunga ubuzima bihura n’intego za ESG z’ibigo, cyane cyane mu Burayi no muri Amerika ya Ruguru, aho abaguzi n’abashoramari barushaho gusaba ko habaho ubwisanzure mu bijyanye n’ibicuruzwa.
Iyi gahunda yo kwibanda ku kubungabunga ibidukikije irimo no kuvugurura imiterere y'isoko. Urugero, urwego rw'ubuvuzi ubu rugaragaza ibikoresho bitagira uburozi bifasha mu gusuzuma no gupakira ibikoresho, bigatuma iterambere ryabyo rigera kuri 18% buri mwaka muri uru rwego. Mu buryo nk'ubwo, inganda z'ubwubatsi—zifite ibirenga 60% by'ibikenewe muri PVC—zishyira imbere ibikoresho bifasha mu kubungabunga ibidukikije birushaho gukomera no kongera gukoreshwa, bishyigikira ibyemezo by'inyubako zidafite ibidukikije.
Imbogamizi n'Inzira Imbere
Nubwo hari intambwe imaze guterwa, imbogamizi ziracyahari. Ibiciro by'ibicuruzwa bya zinc bihindagurika (bingana na 40-60% by'ibiciro by'ibikoresho fatizo bya Ca-Zn) biteza ibibazo mu ruhererekane rw'ibicuruzwa. Hagati aho, ikoreshwa ry'ubushyuhe bwinshi riracyagerageza aho ibipimo bidashobora kurengera ibidukikije bigarukira, bigasaba ubushakashatsi n'iterambere bikomeje kugira ngo harebwe icyuho mu mikorere.
Nyamara inzira irasobanutse: Ibintu bitera imbaraga bya PVC birimo guhinduka kuva ku nyongeramusaruro gusa kugeza ku bikoresho bitera imbaraga ibicuruzwa bya PVC birambye. Ku bakinnyi bo mu nzego nka Venetian blinds—aho kuramba, ubwiza, n'ibyangombwa by'ibidukikije bihurira—gukoresha ibyo bintu bitera imbaraga byo mu gihe kizaza si ngombwa gusa ahubwo ni inyungu yo guhangana. Uko umwaka wa 2025 ugenda utangira, ubushobozi bw'inganda bwo kuringaniza imikorere, umutekano, no kongera gukoreshwa buzagena uruhare rwazo mu iterambere ry'isi yose ku bikoresho bizengurutse.
