Uko ibihe bigenda bisimburana, abantu bagenda barushaho kwita ku kurengera ibidukikije, kandi iterambere ry’inganda ritangiza ibidukikije ryabaye ikintu gishya. Kubwibyo, ibikoresho bishobora kubora ni ngombwa. None se ibikoresho bishingiye ku binyabuzima ni iki?

Ibikoresho bishingiye ku binyabuzima bivuga umutungo kamere w’ibinyabuzima bishobora kongera gukoreshwa binyuze muri fotosite nk’ibikoresho fatizo, bihinduka ibikomoka ku binyabuzima binyuze mu ikoranabuhanga rya fermentation, hanyuma bigatunganywa bigahindurwamo ibikoresho bya polymer bitangiza ibidukikije. Ibikoresho bishobora kubora bishobora kubora bikavamo CO2 na H20 bitewe n’imikorere ya mikorobe cyangwa ifumbire. Ugereranyije n’ibikomoka kuri peteroli, ibikoresho bishingiye ku binyabuzima bishobora kugabanya imyuka ihumanya ikirere kugeza kuri 67%.

Ibyuka bihumanya ikirere bisanzwe mu gihe cyose cyo gukora polymer zimwe na zimwe (kg CO2/kg products):

Mu buzima bwa buri munsi, ntabwo dushobora kubaho tudafite ibikoresho bya pulasitiki, ariko twese tuzi ko pulasitiki idahungabanya ibidukikije kandi ko ari yo musaruro nyamukuru w’ “imyanda y’umweru”. Ariko, ibikoresho bya pulasitiki biri hose mu buzima bwacu bwa buri munsi. Kubera iyo mpamvu, pulasitiki yangirika buhoro buhoro yagiye iba ikintu gishya.

Kugira ngo ibyo bigerweho, abahanga mu bya siyansi bakoze ikintu gishobora kubora –aside polylacticIyi plastiki, ivanywe mu bimera, ifite ubushobozi bwo kwangirika neza kandi irinda ibidukikije bitewe n'uburyo itegurwa, ikavanaho ibikoresho fatizo bya peteroli bitangiza ibidukikije. Aside ya polylactic (PLA) ubu ni imwe mu bikoresho bikoreshwa cyane, bitanga icyizere kandi bihendutse.

PLA ni iki?

Aside lactic (poly), muri make nkaPLA, izwi kandi nka aside polylactic,CAS 26100-51-6cyangwaCAS 26023-30-3Aside ya polylactic ikorwa mu bimera nk'ibikoresho fatizo, bikomoka ku bidukikije kandi bikaba ibya kamere. Uburyo PLA ihinduramo ni ubu bukurikira - abahanga mu bya shimi bashobora guhindura neza ibinyampeke biva mu bihingwa nk'ibigori muri LA binyuze mu nzira za hydrolysis na mikorobe, hanyuma bakayihindura PLA binyuze mu gupomera amazi cyangwa gupomera amazi, bigatuma habaho "ubumaji" bwo guhindura ibihingwa muri plastiki.

Ni ibihe biranga aside polylactic n'ibyiza byayo?

Bishobora kwangirika burundu

Bitewe n’udukoko cyangwa uburyo bwo gufumbira, ishobora kwangirika burundu ikaba CO2 na H2O, kandi igipimo cyo kwangirika kw’ibinyabuzima gishobora kugera kuri 90% nyuma y’iminsi 180.

Imiterere karemano yo kurwanya indwara ziterwa na antibiyotike

Ifite ubushobozi bwo gukumira Candida albicans, Escherichia coli na Staphylococcus aureus.

Kuba bihuye n'ibinyabuzima

Aside lactic y'ibikoresho fatizo ni ikintu kiboneka mu mubiri w'umuntu, naho PLA ni ibikoresho byashyizwe mu mubiri w'umuntu byemejwe na FDA, byakoreshejwe cyane mu buvuzi.

Uburyo bwiza bwo gutunganya ibintu

Ubushyuhe bwo gutunganya PLA ni 170 ~ 230 ℃, kandi uburyo butandukanye bwo gutunganya nko gusohora, kunagura, kuzunguza, gusohora filime, gushushanya mu nganda, gushushanya mu buryo bwa "blow molding", no gushushanya mu buryo bwa "blister" bushobora gukoreshwa mu gushushanya.

Kudashya

Ntishobora gushya, ifite igipimo cya ogisijeni kingana na 21%, umwotsi muke uturuka mu kirere, kandi nta mwotsi w'umukara uturukamo.

Ibikoresho fatizo bishobora kongera gukoreshwa

Ibikoresho fatizo bya PLA bikomoka ku masoko ya karuboni ya biomass yakozwe na fotosite.

Bitewe no kongerera ubumenyi abantu ku bidukikije buhoro buhoro, pulasitiki zishobora kwangirika zizasimbura ibikoresho fatizo bya peteroli bitangiza ibidukikije. Bitewe n'uko sosiyete ikomeje kwemerwa na pulasitiki zishobora kwangirika,PLAbizagera ku ntego mu bindi bice biri inyuma y’uruzi mu gihe kizaza.
