Iingxowa zeplastiki ezihambelana nokusingqongileyo zimfutshane kwiintlobo ngeentlobo zeengxowa zeplastiki ezinokubola.Ngophuhliso lwetekhnoloji, izinto ezahlukeneyo ezinokutshintsha iiplastiki ze-PE zemveli zivela, kubandakanya i-PLA, i-PHAs, i-PBA, i-PBS kunye nezinye izinto ze-polymer.Inokutshintsha iingxowa zeplastiki ze-PE zesintu.Iingxowa zeplastiki zokukhuselwa kwendalo zisetyenziswa ngokubanzi: iingxowa zokuthenga ezivenkileni ezinkulu, iingxowa zokugcina ii-roll-to-roll ezintsha, kunye neefilimu zemulch zisetyenziswa kakhulu eTshayina.IPhondo laseJilin liye lamkela i-PLA (i-polylactic acid) endaweni yeengxowa zeplastiki zendabuko, kwaye iphumelele iziphumo ezilungileyo.KwisiXeko saseSanya, kwiPhondo laseHainan, iingxowa zeplastiki ezinokonakala ezisekwe kwisitatshi nazo ziye zasetyenziswa kakhulu kumashishini anjengeevenkile ezinkulu kunye neehotele.
Ngokuqhelekileyo, akukho ngxowa yeplastiki ehambelana ngokupheleleyo nokusingqongileyo.Kuphela iingxowa zeplastiki ezinokuthi zonakaliswe ngokulula emva kokongeza izithako.Oko kukuthi, iplastiki ye-biodegradable.Yongeza inani elithile lezongezo (ezifana nesitashi, isitashi esilungisiweyo okanye enye i-cellulose, i-photosensitizers, i-biodegradants, njl.) kwinkqubo yokuvelisa iimveliso zokupakisha zeplastiki ukunciphisa ukuzinza kokupakishwa kweplastiki kwaye kube lula ukuthotywa kwimeko yendalo .Kukho iiyunithi ezili-19 eziphuhlisa okanye ezivelisa iiplastiki ezinokubola eBeijing.Iimvavanyo zibonise ukuba iiplastiki ezininzi ezonakalisayo ziqala ukuba zincinci, zinciphise umzimba, kwaye zilahlekelwe amandla emva kokuvezwa kwindawo eqhelekileyo kwiinyanga ezi-3, kwaye ngokuthe ngcembe ziqhekeke.Ukuba ezi ziqwenga zingcwatywe kwinkunkuma okanye emhlabeni, umphumo wokuthotywa awubonakali.Kukho iziphene ezine ekusetyenzisweni kweeplastiki ezinokonakala: enye kukutya ukutya okuninzi;enye yeyokuba ukusetyenziswa kweemveliso zeplastiki ezonakeleyo akusenakukuphelisa ngokupheleleyo “ungcoliseko olubonakalayo”;okwesithathu kukuba ngenxa yezizathu zobugcisa, ukusetyenziswa kweemveliso zeplastiki ezichithwayo akukwazi ukusombulula ngokupheleleyo impembelelo yokusingqongileyo "Iingozi ezinokwenzeka";Okwesine, iiplastiki ezonakeleyo kunzima ukuzisebenzisa kwakhona kuba zinezongezo ezikhethekileyo.
Enyanisweni, eyona nto ihambelana nokusingqongileyo kukusebenzisa iingxowa zeplastiki okanye iiplastiki ezisisigxina ukunciphisa inani lokusetyenziswa.Kwangaxeshanye, inokuphinda isetyenziswe ngurhulumente ukunciphisa ukungcoliseka kwendalo.
