Urutonde rw'abagomba guhabwa igihembo cya Polyurethane mu 2025 rwatangajwe, ikoranabuhanga rishingiye ku binyabuzima ryafashe umwanya wa mbere

Vuba aha, Ikigo cy’Inganda za Polyurethane (CPI) kiri mu Nama y’Abanyamerika ishinzwe Ubutabire (ACC) cyashyize ahagaragara ku mugaragaro urutonde rw’abazahatanira igihembo cya Polyurethane mu 2025. Nk’ikimenyetso cy’icyubahiro mu nganda za polyurethane ku isi, iki gihembo kimaze igihe kinini kigamije gushimira iterambere rikomeye mu kubungabunga ibidukikije, imikorere myiza, n’imikorere myinshi y’ibikoresho bya polyurethane. Urutonde rw’abazahatanira uyu mwaka rwakunzwe cyane, aho ikoranabuhanga ribiri rigezweho ryibanda ku guhanga udushya bishingiye ku binyabuzima n’ibikomoka ku bidukikije byabonye umwanya. Kuba bikubiye muri ibyo bikoresho ntibigaragaza gusa ubushake budasubirwaho bw’inganda mu kubungabunga ibidukikije, ahubwo binagaragaza ko ikoranabuhanga rishingiye ku binyabuzima ryagaragaye nk'ikintu cy’ingenzi mu guhanga udushya no kuvugurura urwego rwa polyurethane.

Ibikoresho bya polyurethane, bizwiho imikorere myiza cyane, bikoreshwa cyane mu nganda zikomeye nko mu bwubatsi, mu nganda zikora imodoka, mu gupakira no mu buvuzi. Ariko, inzira gakondo zo gukora zishingiye ku mavuta akomoka ku bimera, kandi ibicuruzwa bya nyuma akenshi ntibishobora kwangirika, bigatuma inganda zihura n’ibibazo bibiri by’ibidukikije n’imbogamizi ku mutungo. Mu gihe cy’intego zo kurengera ibidukikije ku isi, gukaza amategeko agenga ibidukikije, no kwiyongera k’ubukene bw’ibicuruzwa bikomoka ku bimera, guteza imbere ikoranabuhanga rya polyurethane ritangiza umwanda, rishobora kongera gukoreshwa, ryabaye ikintu kidasubirwaho mu guhindura inganda. Ikoranabuhanga ribiri ryashyizwe ku rutonde ni ryo rigaragaza ibyo uyu muco wagezeho, ritanga ibisubizo bifatika ku mpinduka mu nganda za polyurethane.

Muri byo, Soleic® yakozwe na Algenesis Labs yashimwe cyane kubera imiterere yayo ishingiye ku binyabuzima 100% n'imikorere yayo ihebuje mu bidukikije. Nk'ubwoko bwa polyester polyol bufite isuku nyinshi, Soleic® yabonye icyemezo cyayo muri gahunda ya BioPreferred® ya Minisiteri y'Ubuhinzi ya Amerika (USDA)—ikimenyetso gikomeye kigaragaza ko ikurikiza amahame mpuzamahanga agenga ibikomoka ku binyabuzima, bigatuma ikomera nk'ibikoresho bishobora kongera gukoreshwa kandi bitangiza ibidukikije. Bitandukanye na polyol zisanzwe za polyester zikomoka ku biryo bikomoka kuri peteroli, udushya twa Soleic® dushingiye ku gushaka ibikoresho fatizo birambye: ikoresha algae n'ibihingwa bitari ibyo kurya nk'umusaruro w'ibanze. Algae, umutungo kamere ufite uruziga rugufi cyane rwo gukura kandi ufite ubushobozi bukomeye bwo kororoka, ntabwo isaba gusa ubutaka bwo guhinga (kwirinda guhangana n'umusaruro w'ibiribwa) ahubwo inafata dioxyde de carbone nyinshi mu gihe cyo gukura, bigafasha mu kugabanya imyuka ihumanya ikirere. Gushyiramo ibihingwa bitari ibyo kurya nk'ibyatsi n'urusenda birushaho kongera ubushobozi bwo kongera gukoresha umutungo kamere mu gihe bigabanya imyuka ihumanya ikirere.

Icy'ingenzi kurushaho, ibicuruzwa byakozwe na Soleic® bigaragaza ubushobozi bwo kwangirika neza. Mu bidukikije karemano (nk'ubutaka, amazi yo mu nyanja, cyangwa ahantu ho gufumbira mu nganda), ibi bicuruzwa bishobora kwangirika burundu na mikorobe mu mazi na dioxyde de carbone nta gusiga ibisigazwa byangiza, ahanini bigakemura ikibazo cy'umwanda wa microplastic uterwa n'ibicuruzwa gakondo bya polyurethane bitakoreshejwe. Muri iki gihe, Soleic® yakoreshejwe cyane mu ifuro ryoroshye, irangi, kole, ibikoresho byo gupfunyika, n'ibindi. Ntabwo igera gusa ku iterambere mu mikorere y'ibidukikije ahubwo inahura n'amahame akomeye mu nganda mu bipimo by'ingenzi nko mu miterere ya mekanike no kwirinda ubushyuhe, bigatuma habaho "inyungu kuri buri wese" hagati yo kubungabunga ibidukikije n'imikorere. Ibi biha ibigo byo hasi inkunga y'ibikoresho fatizo byo guteza imbere ibicuruzwa bihumanya ibidukikije.

Irindi koranabuhanga ryatoranyijwe ni HandiFoam® E84 ifite ibice bibiri bya polyurethane foam system yatangijwe na ICP. Ishingiye ku ikoranabuhanga rya Hydrofluoroolefin (HFO) rigezweho, iki gicuruzwa cyibanda ku kunoza imikorere myiza y'ingufu no kunoza imikorere y'ibidukikije, bihabwa icyemezo cya UL GREENGUARD Gold—ikimenyetso cyemewe cy'uko gifite imyuka mike ya Volatile Organic Compound (VOC). Iki cyemezo cyemeza ko HandiFoam® E84 itangiza ubwiza bw'umwuka wo mu nzu mu gihe cyo kuyikoresha, bigatuma iba igicuruzwa cyiza cyane gishyira mu gaciro ku kurengera ibidukikije n'ubuzima.

Mu bijyanye n'udushya mu ikoranabuhanga, HFO ikoreshwa muri HandiFoam® E84 ikora nk'uburyo bworohereza ibidukikije aho gukoresha Hydrofluorocarbon (HFC) isanzwe ikoreshwa mu gushyushya. Ugereranyije na HFC, HFO zifite ubushobozi buke cyane bwo gushyushya isi (GWP), zigabanya cyane imyuka ihumanya ikirere kandi zikagabanya kwangirika kwa ozone. Ibi bihuye na politiki mpuzamahanga yo kubungabunga ibidukikije ishyigikira ibisabwa kuri firigo n'ibikoresho bishyushya. Nk'ifuro rya polyurethane rikoresha ibice bibiri, HandiFoam® E84 ifite ubushobozi bwiza bwo gushyushya no gufunga, cyane cyane ko ikora neza mu rwego rwo gukoresha ingufu mu nyubako. Iyo ikoreshejwe ku nkuta zo hanze, ku nzugi/amadirishya, no ku bisenge by'inyubako, ikora urwego ruhoraho kandi rufite ubushobozi bwo gushyushya rugabanya cyane ubushyuhe hagati y'ahantu ho mu nzu no hanze, ikagabanya ikoreshwa ry'ingufu mu byuma bikonjesha n'ubushyuhe. Nk'uko byagaragajwe, inyubako zikoresha HandiFoam® E84 zishobora kugabanya ikoreshwa ry'ingufu ku kigero cya 20%-30%, zitazigama gusa ikiguzi cy'ingufu ahubwo zinashyigikira inganda z'ubwubatsi mu kugera ku ntego zo kugabanya imyuka ihumanya ikirere. Byongeye kandi, iki gicuruzwa gitanga ibyiza nko kubaka byoroshye, gushya vuba, no gufata neza, bigatuma gikwirakwira mu bintu bitandukanye birimo inyubako zo guturamo, inyubako z'ubucuruzi, ububiko bw'ibikoresho bikonjesha, n'ibikoresho by'inganda, bityo kikaba gifite amahirwe menshi yo gukoreshwa ku isoko ryagutse.

Itangazo ry'urutonde rw'abazahabwa igihembo cya Polyurethane Innovation Award cyo mu 2025 ntiryemeza gusa udushya mu ikoranabuhanga rya Algenesis Labs na ICP, ahubwo rinagaragaza icyerekezo cy'iterambere ry'inganda za polyurethane ku isi—ikoranabuhanga rishingiye ku binyabuzima, ikoreshwa rya karubone nke, n'ikoreshwa ry'uruziga byabaye amagambo y'ingenzi mu guhanga udushya mu nganda. Mu gihe cy'izamuka ry'ibidukikije, ibigo bya polyurethane bishobora kubona inyungu mu guhangana gusa binyuze mu kwibanda ku bushakashatsi n'iterambere mu ikoranabuhanga rirambye, mu gihe bitanga umusanzu mu kurengera ibidukikije ku isi no kugera ku ntego zo kwirinda karubone. Mu gihe kizaza, hamwe no kugabanuka kw'ibiciro by'ibikoresho fatizo bishingiye ku binyabuzima no gukomeza gukoresha ikoranabuhanga mu bidukikije, inganda za polyurethane zitezweho kugera ku mpinduka zirambye mu kubungabunga ibidukikije, zitanga ibisubizo by'ibikoresho birengera ibidukikije, binoze kandi birambye ku nzego zitandukanye zikoreshwa.
