Ngokuphuculwa okuqhubekayo kolwazi lwendalo esingqongileyo, ishishini lezithambiso likwangenise utshintsho oluluhlaza ekupakisheni. I-petroleum-based based packaging yeplastiki ayidli kuphela izibonelelo ezininzi ngexesha lenkqubo yokuvelisa, kodwa ibangela ukungcoliseka okunzulu kokusingqongileyo ngexesha lonyango emva kokusetyenziswa. Ke ngoko, ukuphonononga izinto zokupakisha ezizinzileyo kuye kwaba ngumba obalulekileyo kwishishini lezithambiso.
Iiplastiki ezisekelwe kwipetroleum
Iiplastiki ezisekelwe kwipetroleum luhlobo lwemathiriyeli yeplastiki eyenziwe ngamafutha efosili afana nepetroleum. Ineplastiki elungileyo kunye neempawu zoomatshini, ngoko ke isetyenziswa kakhulu kwiinkalo ezahlukeneyo. Ngokukodwa, iiplastiki ezisekwe kwipetroleum ziquka ezi ntlobo zilandelayo:
Polyethylene (PE)
Ipolypropylene (PP)
Ipolyvinyl chloride (PVC)
Ipolystyrene (PS)
Polycarbonate (PC)
Iiplastiki ezisekelwe kwipetroleum zilawula ukupakishwa kwezithambiso ngenxa yobunzima bazo, ukuqina kunye nokusebenza kakuhle kweendleko. Iiplastiki ezisekelwe kwipetroleum zinamandla aphezulu kunye nokuqina, ukumelana neekhemikhali ezingcono kunye nokuqhubekeka okungcono kuneeplastiki zemveli. Noko ke, ukuveliswa kwesi sixhobo kufuna izixa ezikhulu zemithombo yepetroleum, nto leyo ebangela ukuncipha kobutyebi bomhlaba. Ukukhutshwa kwe-CO2 eveliswa ngexesha lenkqubo yokuvelisa iphezulu kwaye kunempembelelo ethile kwindalo. Ngelo xesha, ukupakishwa kweplastiki kudla ngokulahlwa ngokungaqhelekanga emva kokusetyenziswa kwaye kunzima ukuthotywa emva kokungena kwindawo yendalo, kubangela umonakalo omkhulu kumhlaba, imithombo yamanzi kunye nezilwanyana zasendle.
Izisombululo zokuyila ezintsha zokupakishwa okuzinzileyo
Iplastiki esetyenzisiweyo
Iplastiki esetyenzisiweyo luhlobo olutsha lwemathiriyeli eyenziwe ngenkunkuma yeplastiki ngeenkqubo ezinjengokutyumza, ukucoca, kunye nokunyibilikiswa. Ineempawu ezifanayo kwiplastiki enyulu, kodwa isebenzisa izixhobo ezimbalwa kakhulu kwimveliso yayo. Ukusebenzisa iiplastiki ezihlaziyiweyo njengezinto zokupakisha zokuthambisa akunakunciphisa kuphela ukuxhomekeka kwimithombo yepetroleum, kodwa nokunciphisa ukukhutshwa kwekhabhoni ngexesha lenkqubo yokuvelisa.
I-Bioplastiki
I-Bioplastic yimathiriyeli yeplastiki ecutshungulwa kwimithombo ye-biomass (efana nestatshi, i-cellulose, njl.) ngokusebenzisa i-biological fermentation, synthesis kunye nezinye iinkqubo. Ineempawu ezifanayo kwiiplastiki zendabuko, kodwa inokunciphisa ngokukhawuleza kwindawo yendalo kwaye ihambelana nokusingqongileyo. Iimathiriyeli ekrwada ye-bioplastics zivela kuluhlu olubanzi lwemithombo, kubandakanywa izitro zezityalo, inkunkuma yeenkuni, njl., kwaye zihlaziywa kakhulu.
Izixhobo zokupakisha ezizezinye
Ukongeza kwiiplastiki ezisetyenzisiweyo kunye ne-bioplastics, zininzi ezinye izinto zokupakisha ezizinzileyo ezikhoyo. Ngokomzekelo, izinto zokupakisha zamaphepha zineenzuzo zokuba zilula, zihlaziywa kwaye zihlanjululwe, kwaye zifanelekile ukusetyenziswa kwipakethe yangaphakathi yezithambiso. Nangona imathiriyeli yokupakisha yeglasi inzima, inokomelela okugqwesileyo kunye ne-recyclability kwaye ingasetyenziselwa ukupakisha izithambiso zokugqibela. Ukongeza, kukho izinto ezintsha ze-bio-based composite, izixhobo zentsimbi, njl.
Iibrendi kunye nabathengi ngokudibeneyo bafezekisa uphuhliso oluzinzileyo
Ukufezekisa uphuhliso oluzinzileyo lokupakishwa kwezithambiso kufuna iinzame ezidibeneyo zeempawu kunye nabathengi. Ngokubhekiselele kwiimpawu, izinto zokupakisha ezizinzileyo kunye nobuchwepheshe kufuneka zihlolwe kwaye zisetyenziswe ukunciphisa impembelelo engalunganga yokupakishwa kokusingqongileyo. Kwangaxeshanye, iibrendi kufuneka zomeleze imfundo yendalo esingqongileyo kubathengi kwaye bakhokele abathengi ukuba baseke iikhonsepthi zokusetyenziswa kohlaza. Abathengi kufuneka banikele ingqalelo kwizinto zokupakisha zeemveliso kwaye banike kuqala kwiimveliso ezinokupakishwa okuzinzileyo. Ngexesha lokusetyenziswa, umthamo wokupakisha osetyenziswayo kufuneka uncitshiswe kangangoko kunokwenzeka, kwaye ukupakishwa kwenkunkuma kufuneka kuhlelwe ngokuchanekileyo kwaye kulahlwe.
Ngokufutshane, inguqu eluhlaza yokupakishwa kwezithambiso yindlela ebalulekileyo yoshishino lwezithambiso ukuphumeza uphuhliso oluzinzileyo. Ngokwamkela izinto zokupakisha ezizinzileyo kunye nobuchwepheshe kunye nokomeleza imfundo yokusingqongileyo, iibrendi kunye nabathengi banokufaka isandla ngokudibeneyo kwikamva leplanethi.
