Ukwaziswa kwemathiriyeli ekrwada yeplastiki enokubola
Igama elithi "iiplastiki eziguquguqukayo eziphilayo" libhekisela kuhlobo lweeplastiki ezinokuhlangabezana neemfuno zokusetyenziswa kunye nokugcina iimpawu zayo ngexesha lokuphila kwayo, kodwa inokuthotywa kwizinto ezinobungane bokusingqongileyo emva kokusetyenziswa phantsi kweemeko zendalo zendalo. Ngokwandisa ukhetho lwemathiriyeli ekrwada kunye nenkqubo yokuvelisa, iplastiki yeBiodegradable inokuboliswa ngokuthe ngcembe ibe ngamaqhekeza kwaye ekugqibeleni ibole ngokupheleleyo phantsi kwesenzo esidityanisiweyo sokukhanya kwelanga, imvula kunye nemicroorganisms kangangeentsuku okanye iinyanga ezininzi.
Izinto ezilungileyo zeplastiki enokubola
Ngexesha le "Ban Plastic" Action kunye nokujongana nemeko yolwazi olwandisiweyo lokusingqongileyo, iplastiki ebolisekayo ibonwa njengendawo ethatha indawo yeplastiki yesiko elahlwayo. Iplastiki ye-Biodegradable iboliswa ngokulula yimekobume yendalo kuneeplastiki zepolymer zemveli, kwaye iyasebenza ngakumbi, yonakala kwaye ikhuselekile. Nokuba iplastiki ye-Biodegradable ingena kwindawo yendalo ngengozi, ayiyi kubangela umonakalo omkhulu kwaye inokunceda ngokungathanga ngqo ukuqokelela inkunkuma yezinto eziphilayo ngelixa inciphisa impembelelo yenkunkuma ephilayo ekubuyiseleni inkunkuma yeplastiki ngoomatshini.
Iplastiki ye-Biodegradable ineenzuzo zayo ekusebenzeni, ukwenzeka, ukuthotywa kunye nokhuseleko. Ngokubhekiselele ekusebenzeni, iplastiki ye-Biodegradable inokufikelela okanye igqithise ukusebenza kweeplastiki zemveli kwiindawo ezithile. Ngelixa ngokwemigaqo yokusebenziseka, iplastiki enokubola iyasebenza ngokufanayo kunye neepropathi zococeko kwiiplastiki zemveli ezifanayo. Ngokubhekiselele kwi-degradability, iplastiki ye-biodegradable inokutshatyalaliswa ngokukhawuleza kwindawo yendalo (ii-microorganisms ezithile, ubushushu kunye nomswakama) emva kokusetyenziswa kwaye ibe yinkunkuma esebenzisekayo ngokulula okanye i-non-toxic gases, ngaloo ndlela inciphisa impembelelo yazo kwindalo. Ngokokhuseleko, izinto eziveliswayo okanye ezishiywe kwiinkqubo zeplastiki zeBiodegradable azinabungozi kokusingqongileyo kwaye azichaphazeli ukuphila kwabantu nezinye izinto eziphilayo. Owona mqobo mkhulu ekutshintsheni iiplastiki zemveli yinto yokuba iplastiki ebolisiweyo yi-biodegradable ibiza kakhulu ukuvelisa kunezinye zazo eziqhelekileyo okanye ezisetyenzisiweyo. Ngenxa yoko, iplastiki ye-biodegradable inenzuzo engaphezulu yokutshintshwa kwizicelo ezifana nokupakishwa, ifilimu yezolimo, njl., apho ixesha lokusetyenziswa lifutshane, ukubuyisela kunye nokwahlula kunzima, iimfuno zokusebenza aziphezulu, kwaye iimfuno zomxholo wokungcola ziphezulu.
Iingxowa zokupakisha ze-Biodegradable
Kule mihla, imveliso ye-PLA kunye ne-PBAT ikhulile ngakumbi, kwaye umthamo wabo wokuvelisa uphelele uphambili kwiplastiki ye-biodegradable, i-PLA inomsebenzi ogqwesileyo, kwaye njengoko iindleko ziwa, kulindeleke ukuba zande ukusuka kwintsimi yezonyango eziphezulu imarike enkulu efana nokupakishwa kunye nefilimu yezolimo kwixesha elizayo. Ezi plastiki zeBiodegradable zinokuba yeyona ndlela iphambili kwiiplastiki zesintu.
Iingxowa zeplastiki ezibanga ukuba ziyakwazi ukubola bezingekaguquguquki kwaye zikwazi ukuthwala iivenkile kwiminyaka emithathu emva kokuvezwa kwendalo, uphando luye lwafumanisa.
Uphando okokuqala ngqa luvavanye iingxowa ezivundisiweyo, iindlela ezimbini zengxowa enokubola kunye neengxowa eziqhelekileyo zokuthwala emva kokuvezwa ixesha elide elwandle, emoyeni nasemhlabeni. Akukho nanye ingxowa ebole ngokupheleleyo kuyo yonke indawo.
Ibhegi evundisiweyo ibonakala ihamba ngcono kunento ebizwa ngokuba yi-biodegradable bag. Isampulu yengxowa evundisiweyo yanyamalala ngokupheleleyo emva kweenyanga ezintathu kwindawo yaselwandle kodwa abaphandi bathi umsebenzi omninzi uyafuneka ukuze kubonwe ukuba zithini na iimveliso zokonakala kunye nokuqwalasela nayiphi na imiphumo enokubakho kokusingqongileyo.
Ngokophando, i-Asiya kunye ne-Oceania i-akhawunti ye-25 yeepesenti yemfuno yehlabathi yeeplastiki ezinokubola, kunye neetoni ezingama-360,000 ezisetyenziswa kwihlabathi jikelele. I-China yenza i-12 lepesenti yemfuno yehlabathi yeeplastiki ezinokubola. Okwangoku, ukusetyenziswa kweeplastiki ze-biodegradable zisembalwa kakhulu, isabelo semarike sisephantsi kakhulu, ubukhulu becala amaxabiso eplastiki e-biodegradable aphezulu, ngoko ukusebenza ngokubanzi akukuhle njengeeplastiki eziqhelekileyo. Nangona kunjalo, kuya kuthatha isabelo esithe chatha kwimarike njengoko abantu besazi ukubaluleka kokusebenzisa iibhegi ezingonakaliswa ngebhayoloji ukusindisa umhlaba. Kwixesha elizayo, ngophando olongezelelekileyo lwetekhnoloji yeplastiki ye-biodegradable, ixabiso liya kuncitshiswa ngakumbi, kwaye imarike yokusetyenziswa kwayo kulindeleke ukuba yande ngakumbi.
Ke ngoko, iibhegi ezinokuboliswa ngebhayoloji ngokuthe ngcembe ziye zibe lukhetho lokuqala lwabathengi. Ipakethe ephezulu igxile ekuphuhliseni olu hlobo lweengxowa iminyaka kwaye ihlala ifumana izimvo ezilungileyo kuninzi lwabathengi.
