Kwiminyaka yakutshanje, kunye nophuhliso olukhawulezayo loqoqosho, ukufuna kwabantu izinto eziphathekayo kunye nezokomoya kuya phezulu nangaphezulu, ukupakishwa kweemveliso kuneemfuno eziphezulu ngokuhambelanayo, xa abantu bethenga iimveliso, bengakhange bajonge nje ubuhle bepakethe, kodwa baqwalasela ezahlukeneyo eminye imisebenzi.Kungenxa yokuphuculwa okuqhubekayo kokusukela kwabantu ukupakishwa kwemveliso, izinto ezininzi zokupakisha ezitsha ziyaqhubeka ukusetyenziswa kwipakethe yemveliso.
Kutheni siphuhlisa imathiriyeli enokubola
Izinto ze-polymer zokwenziwa zineenzuzo zobunzima bokukhanya, amandla aphezulu, uzinzo oluhle lweekhemikhali kunye nexabiso eliphantsi, ngentsimbi, umthi, i-samente ibe yintsika ezine zoqoqosho lwesizwe, isetyenziswa ngokubanzi kwipakethe yemveliso.Nangona kunjalo, isixa esikhulu senkunkuma emva kokusetyenziswa kwayo siyanda imihla ngemihla, ibe ngumthombo wongcoliseko olumhlophe, ingozi enkulu kwindalo esingqongileyo, okubangela ungcoliseko lwamanzi nomhlaba, ingozi ekusindeni kwabantu kunye nempilo, kwindawo yokuphila yabantu kubangele imeko embi. impembelelo ayinakungahoywa.
Ukongeza, ukuveliswa kwezixhobo zepolymer zokwenziwa -- izinto eziluhlaza zepetroleum zihlala ziphelile ngenye imini, ngoko kungxamisekile ukufumana izinto ezintsha ezihambelana nokusingqongileyo, uphuhliso lweepolymers ezingeyopetroleum, kunye nezinto ezinokubola yindlela esebenzayo Sombulula le ngxaki.
Inkcazo yezinto ezinokubola
Izinto eziguquguqukayo ze-Biodegradable, ezaziwa ngokuba "zizixhobo eziluhlaza zendalo", zibhekiselele kwizinto ezinokuthobisa phantsi kwesenzo se-microorganisms zomhlaba kunye ne-enzymes.Ngokukodwa, kuthetha ukuba phantsi kweemeko ezithile, kunokukhokelela kwi-biodegradation yezinto ze-polymer phantsi kwesenzo sebhaktheriya, isikhunta, i-algae kunye nezinye ii-microorganisms zendalo.
Indlela efanelekileyo yokunciphisa umgangatho
Izinto ezifanelekileyo eziguquguqukayo ze-biodegradable luhlobo lwezinto zepolymer ezinomsebenzi ogqwesileyo, ezinokuchithwa ngokupheleleyo ngama-microorganisms okusingqongileyo emva kwenkunkuma, kwaye ekugqibeleni iguqulelwe kwi-CO2 kunye ne-H2O, eba yinxalenye yomjikelezo wekhabhoni kwindalo.
