Sida laga soo xigtay Jaamacadda Portsmouth, koox cilmi-baarayaal ah oo hore u helay enzyme caag-cunida, PETase, ayaa ku daray enzyme kale si ay u dedejiyaan habka xaalufka caaga ah. Tan cusub ee enzyme-ga cusub waxa ay hoos u dhigtaa balaastiigga lix jeer ka dhaqso badan ensaymkii hore, waxaana dhawaan si weyn loogu isticmaali karaa dib u warshadaynta.

Enzymes-cunida caagga ah macnaha guud

Wasakhowga balaastiggu waxa uu wasakheeyey inta badan deegaanka dabiiciga ah ee meeraha; dhab ahaantii, warbixinnada ayaa isa soo taraya kuwaas oo tilmaamaya in dadka ku nool gobollada kala duwan ee adduunka ay neefsanayaan oo ay cunayaan walxaha microplastic. Nasiib wanaag, cilmi-baarayaashu waxay farsameeyeen enzyme super-enzyme ka caawin kara dib-u-warshadaynta caagga. 

Nooca ugu dambeeyay ee enzyme-gan waxaa la sameeyay iyadoo la isku daray laba enzymes oo kala duwan; labadaba waxa laga helay bug-cunida balaastiig ah oo ay Japan heshay 2016. Saynis yahanadu waxay soo saareen nooc injineer ah oo ah enzyme-kii ugu horreeyay 2018, kaas oo burburin kara balaastikada dhowr maalmood gudahood. Enzyme-gii ugu dambeeyay wuxuu u shaqeeyaa lix jeer si degdeg ah, taasoo kor u qaadeysa codsiyada dib-u-warshadaynta mustaqbalka. Tani super-enzyme sidoo kale waxay ku shaqayn kartaa heerkulka qolka. 

Saamaynta qaska

Agaasimaha iyo qoraaga hormuudka ah ee Xarunta Innovation Innovation ee Jaamacadda Portsmouth, John McGeehan, ayaa sheegay in horumarintan isticmaalka enzymes ay tahay tallaabo la taaban karo oo loo qaaday dib-u-warshadaynta caagga iyo yaraynta wasakhowga caagga ah. Waxa kale oo uu xusay in saynisyahannadu ay heleen lacag ku filan oo ay ku sameeyaan tijaabooyin dheeraad ah, natiijada lagu guuleysto waxay la macno tahay in Polyethylene Terephthalate (PET) ee hadda jira dib loo warshadayn karo halkii laga isticmaali lahaa shidaalka fosil si loo soo saaro badeecooyin cusub oo caag ah. 

Waxaa intaa dheer, cilmi-baarayaashu waxay hadda baarayaan sida enzymes-yadan loo sii sifayn karo si ay uga dhigaan inay si dhakhso ah u shaqeeyaan. Isku darka enzymes-cunista caagga ah ee cusub iyo kuwii hore ee hoos u dhigaya fiilooyinka dabiiciga ah waxay awood u siin karaan agabka isku dhafan in si buuxda dib loo warshadeeyo-hannaan aad u adag oo qaali ah illaa 2021.

Intaa waxaa dheer, cilmi-baarayaashu waxay sidoo kale heleen cayayaanka cuna caagadaha kale, sida poliurethane - walxo si ballaaran loo isticmaalo laakiin marar dhif ah dib loo warshadeeyo.

Codsiyada enzymes-cunida caagga ah

Enzymes-cunida caaga ah waxaa loo isticmaali karaa:

• Si faa'iido leh ugu beddelo qashinka caagga ah alaabta ceeriin ee isticmaalka warshadeed ee waxtarka leh.
• La xumeeyay qashinka balaastikada ee mashaariicda waaweyn ee ganacsiga.
• Yaree cabbirka qashin qubka adduunka (oo ay ku jiraan balastarka qashinka Baasifigga ee weyn) oo dib-u-habayn ku samee bay'adaha wasakhdu saamaysay.
• Dib u warshadaynta dharka isku dhafka ah ee warshadaha moodada, ka caawinta qaybta inay gaadho yoolalka qashinka wareegtada ah. 

Su'aalo aad ka faalooto

• Enzymes-cunista balaastiigga ah miyay noqon karaan xalka dhibaatooyinka qashinka caagga ah ee adduunka?
• Sidee ku dhici doontaa in qashinka caagga ah loo maareeyo mustaqbalka?
• Sidee bay hababka maaraynta wasakhda hadda wax u beddelaan marka la soo bandhigo enzymes-kan cusub?
• Dib-u-warshadaynta caagga ah iyada oo loo marayo enzymes-cunida caagga ah ma tahay xal dhaqaale?
