1. Iiplastiki ezinokonakala
Iiplastiki ze-Biodegradable zibhekisela kwiiplastiki ezinezibonakaliso zokusebenza ezahlukeneyo ezinokuhlangabezana neemfuno zokusebenza, izikhombisi zokusebenza azitshintshi ngexesha leshelufu, kwaye zinokutshatyalaliswa zibe ngamacandelo angangcolisi imo engqongileyo phantsi kwempembelelo yendalo emva kokusetyenziswa.Ukuhlelwa kweeplastiki ezinokonakala.Ngokwefomu yokuthotywa, iiplastiki ezonakaliswayo zinokwahlulwa zibe ziindidi ezine: iiplastiki ezinokonakala, iiplastiki ezinomfanekiso, iiplastiki ezithatha iifoto kunye nezinokonakala, kunye neeplastiki ezonakaliswa ngamanzi.Ngokohlelo lwemathiriyeli ekrwada, iiplastiki ezonakaliswayo zinokwahlulwa zibe ziiplastiki ezinokonakala kunye ne-petroleum-based degradable plastics.Izinto eziluncedo kwiiplastiki ezonakeleyo.Iiplastiki ze-Biodegradable zineenzuzo zazo ngokwezalathisi zokusebenza, ukusebenziseka, ukuthotywa, kunye nemiba yokhuseleko.Ngokwezalathisi zokusebenza, iiplastiki ezinokonakala zinokufikelela okanye zigqithise izalathisi zokusebenza zeeplastiki zemveli kwezinye iinkalo ezikhethekileyo;ngokubhekiselele kwizinto ezisebenzayo, iiplastiki ezichithwayo zinezibonakaliso zokusebenza zesicelo ezifanayo kunye nokusebenza okucocekileyo njengeeplastiki zendabuko zohlobo olufanayo;ngokwemiqathango yokuthotywa Emva kokusetyenziswa, iiplastiki ezinokonakala zinokutshatyalaliswa ngokukhawuleza phantsi kweempembelelo zendalo kwaye ziguquke zibe ngamaqhekeza okanye iigesi ezingezizo ezinobuthi ezisetyenziswa lula yindalo yendalo, ukunciphisa impembelelo kwindalo yendalo;ngokwemiba yokhuseleko, iiplastiki ezonakeleyo Amacandelo okanye iintsalela ezenziwe ngexesha lenkqubo yokuthotywa aziyi kungcolisa indalo esingqongileyo kwaye aziyi kuchaphazela ukuphila kwabantu nezinye izinto eziphilayo.Umqobo oyintloko wokutshintsha iiplastiki zemveli kweli nqanaba kwakhona kukungonakali kweeplastiki ezonakeleyo, oko kukuthi iindleko zabo zemveliso ziphezulu kunohlobo olufanayo lweeplastiki zemveli okanye iiplastiki ezihlaziyiweyo.
2. Iiplastiki ezisetyenzisiweyo
Iiplastiki ezisetyenzisiweyo zibhekiselele kwizinto zeplastiki ezisetyenzisiweyo ezifunyenwe emva kokucubungula inkunkuma yeplastiki ngeendlela eziphathekayo okanye zekhemikhali ezifana nokulungiswa kwangaphambili, i-granulation enyibilikayo, ukuguqulwa, njl. inokwenza kuphela imiba ethile yeepropati zeplastiki ngokweemfuno zesalathisi sokusebenza ezahlukeneyo, kwaye ivelise iimveliso ezihambelanayo.Ngethuba nje i-recycling frequency ingekho phezulu kakhulu, iiplastiki ezisetyenzisiweyo zinokuqinisekisa izikhombisi zokusebenza ezifanayo njengeeplastiki zendabuko, okanye izinto ezihlaziyiweyo zinokuxutywa kunye nezinto ezintsha zokugcina izikhombisi zokusebenza ezizinzileyo.Nangona kunjalo, emva kwemijikelo emininzi, izikhombisi zokusebenza zeeplastiki ezisetyenzisiweyo ziyancipha kakhulu okanye zingasebenziseki.
3. Iplastiki ye-Biodegradable pK eyenziwe ngokutsha
Ngokuthelekisa, iiplastiki ezonakeleyo zinokusebenza okuzinzile kunye neendleko eziphantsi zokuphinda zisetyenziswe.Banenzuzo yokutshintsha ukupakishwa, iifilimu ze-mulch yezolimo kunye nezinye izicelo ezinamaxesha amafutshane okusetyenziswa kwaye azikwazi ukwahlula kwaye zisetyenziswe kwakhona;ngelixa iiplastiki ezisetyenzisiweyo zinexabiso eliphantsi kunye neendleko zokucubungula zinenzuzo ngakumbi kwiinkalo zesicelo ezifana nezidingo zemihla ngemihla, izinto zokwakha, kunye nezixhobo zombane ezinobomi benkonzo ende kwaye kulula ukuzihlela kunye nokuphinda zisetyenziswe.Zombini ziyaphelelisana.Ungcoliseko olumhlophe luvela ikakhulu kwishishini lokupakisha, kwaye iiplastiki ezonakeleyo zinegumbi elikhulu lokudlala.Ngokuqhubela phambili kwemigaqo-nkqubo kunye nokunciphisa iindleko, ishishini leplastiki elinokonakala linethemba elibanzi kwixesha elizayo.Kwishishini lokupakisha, ukutshintshwa kweeplastiki eziguquguqukayo ze-biodegradable sele zisekiwe.Iiplastiki zinoluhlu olubanzi lwezicelo, kwaye amashishini ahlukeneyo anemigangatho eyahlukeneyo yeeplastiki.Iimfuno eziqhelekileyo zeplastiki kumashishini afana neemoto kunye nezixhobo zekhaya kukuba zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala.Kumashishini okupakisha afana neengxowa zokupakisha zeplastiki, iibhokisi zokutya okukhawulezayo, iifilimu ze-mulch yezolimo, kunye nokuhanjiswa okucacileyo, kuba ukusetyenziswa kwee-monomers zeplastiki kuphantsi kwaye kulula ukungcolisa, abanako ukwahlulwa ngokufanelekileyo.Oku kwenza ukuba iiplastiki ezonakeleyo zibe lula ukuba zithathe indawo yeeplastiki zemveli kula mashishini.
Iiplastiki ezibolisiweyo zisisisombululo esisebenza ngakumbi kungcoliseko olumhlophe kunokuhlaziya iplastiki.I-59% yongcoliseko olumhlophe luvela kwipakethe kunye neemveliso zeplastiki zesigcina-kufuma kwezolimo.Nangona kunjalo, iiplastiki zolu hlobo lokusetyenziswa ziyalahlwa kwaye kunzima ukuphinda zisetyenziswe, nto leyo eyenza ukuba zingakulungeli ukuphinda kusetyenziswe iplastiki.Kuphela ziiplastiki ezonakeleyo ezinokusombulula ingxaki yongcoliseko olumhlophe.Ngaphandle kweeplastiki ezisekelwe kwisitatshi, ixabiso eliqhelekileyo lokuthengisa lezinye iiplastiki ezinokonakala yi-1.5 ukuya ku-4 ngokuphindwe kabini kuneeplastiki zesintu.Oku ikakhulu ngenxa yokuba inkqubo yokuvelisa iiplastiki ezonakeleyo zintsonkothe ngakumbi kwaye zifuna ukusetyenziswa kwee-biomolecules zendalo ezibizayo ze-polymerization, ezonyusa ngokungabonakaliyo iindleko zemveliso.Kumashishini anovakalelo kwiindleko kunye nokusebenza, iiplastiki zemveli zisagcina iinzuzo zabo ngokubhekiselele kubukhulu, ixabiso kunye nokusebenza okubanzi, kwaye isikhundla sabo sihlala siqinile kwixesha elifutshane.Iiplastiki ezibolisiweyo ikakhulu zithatha indawo yoshishino lweplastiki yemveli eqhutywa yimigaqo-nkqubo kwaye inovakalelo olusezantsi ngokwentelekiso.
