SINGAPORE: Waxaa laga yaabaa inaad u malaynayso in ka beddelashada caagadaha hal-isticmaalka ah ee beddelka caagagga biodegradable ay u wanaagsan tahay deegaanka laakiin Singapore, ma jiraan "wax kala duwanaansho wax ku ool ah", khubaradu waxay yiraahdeen.
Inta badan waxay ku dhamaadaan isku meel - gubashada, ayuu yiri ku-xigeenka Professor Tong Yen Wah oo ka tirsan Waaxda Kiimikada iyo Biomolecular Engineering ee Jaamacadda Qaranka ee Singapore (NUS).
Qashinka balaastiigga ah ee nooluhu waxa uu isbeddel ku sameeyaa deegaanka oo keliya marka lagu aaso meelaha qashin-qubka, ayuu raaciyay.
"Xaaladahan, bacahaan waxay si degdeg ah u hoos u dhici karaan marka loo eego bac caag ah oo polyetylen ah oo aan wax saameyn ah ku yeelan doonin deegaanka.Guud ahaan Singapore, xitaa waxaa laga yaabaa inay aad qaali u tahay in la gubo balaastikada noolaha," ayuu yiri Assoc Prof Tong.Waxa uu sharaxay in tani ay tahay sababtoo ah qaar ka mid ah doorashooyinka biodegradable waxay qaataan kheyraad badan si ay u soo saaraan, taas oo ka dhigaysa mid aad qaali u ah.
Aragtidu waxay barbar socotaa waxa Dr Amy Khor, oo ah Wasiiru-dawlaha Deegaanka iyo Khayraadka Biyaha ka sheegay baarlamaanka bishii Agoosto - in qiimaynta meertada nolosha ee bacaha iyo waxyaalaha la iska tuuro ee ay samaysay Hay'adda Deegaanka Qaranka (NEA) ay ogaatay in beddelka lagu sameeyay. balaastikada leh noocyada kale ee alaabta baakadaha la isticmaalo "ma ahan mid u fiican deegaanka".
"Singabuur, qashinka waa lagu gubaa oo aan looga tagin meelaha qashinka lagu shubo si loo xaalufiyo.Tani waxay ka dhigan tahay in shuruudaha kheyraadka ee bacaha oxo-jabku ay la mid yihiin tan bacaha, sidoo kale waxay leeyihiin saameyn la mid ah deegaanka marka la gubo.
"Intaa waxaa dheer, bacaha oxo-degradable waxay faragelin karaan habka dib-u-warshadaynta marka lagu daro balaastikada caadiga ah," ayuu yiri daraasadda NEA.
Balaastigga Oxo-degradable si dhakhso ah ayey u kala jajabaan qaybo yaryar iyo kuwo yaryar, oo loo yaqaanno microplastics, laakiin ha ku jabin heerka molecular ama polymer sida balaastig biodegradable iyo bacrin ah.
Microplastics-ka soo baxay ayaa looga tagayaa deegaanka si aan xad lahayn ilaa ay ugu dambeyntii si buuxda u burburaan.
Midowga Yurub (EU) ayaa dhab ahaantii go'aansaday bishii Maarso in la mamnuuco waxyaabaha ka samaysan caagagga oxo-degroded oo ay barbar socdaan mamnuucidda caagadaha hal mar la isticmaalo.
Marka la samaynayo go'aanka, Midowga Yurub wuxuu yiri balaastig oxo-degradable "si habboon uma aha biodegrade sidaas darteedna waxay gacan ka geysataa wasakhowga microplastic ee deegaanka".
