Wakhe weva ntoni ngezinto zeplastiki ongazange uve ngazo?
Izinto zeplastiki ezinobuhlobo nendalo ezifana neemveliso zephepha kunye neemveliso zoqalo ziye zatsala umdla wabantu.Ke ukongeza kwezi, zeziphi izinto ezintsha zendalo ezizezinye ezikhoyo?
1) Ukhula lwaselwandle: impendulo kwingxaki yeplastiki?
Ngophuhliso lwe-bioplastics, ukhula lwaselwandle lube yenye yezona zinto zithatha indawo yokupakishwa kweplastiki yemveli.
Ekubeni ukutyalwa kwayo akusekelwe kwizinto ezisekelwe kumhlaba, ayiyi kubonelela nayiphi na into kwiingxabano eziqhelekileyo zokukhutshwa kwekhabhoni.Ukongeza, ukhula lwaselwandle aludingi ukusebenzisa isichumisi.Inceda ukubuyisela impilo ye-ecosystem yayo ethe ngqo yaselwandle.Ayisiyiyo kuphela i-biodegradable, kodwa iyakwazi ukuvundiswa ekhaya, oku kuthetha ukuba akufuneki ukuba ichithwe yi-chemical reaction kumaziko oshishino.
I-Evoware, isiqalo sokupakisha esizinzileyo sase-Indonesia, senze ipakethe yesiko ebomvu yealgae enokuhlala ukuya kuthi ga kwiminyaka emibini kwaye inokutyiwa.Ukuza kuthi ga ngoku, iinkampani ezingama-200 kumashishini okutya, izinto zokuthambisa kunye neempahla ezilukiweyo bezivavanya imveliso.
I-notpla yaseBritani yokuqaliswa kwayo iye yaphuhlisa uluhlu lokutya okusekwe elwandle kunye nokupakishwa kwesiselo, njengeengxowa zeketchup ezinokunciphisa ukukhutshwa kwekhabhoni diokside ngama-68%.
Ebizwa ngokuba yi-oohos, isetyenziselwa ukupakishwa okuthambileyo kweziselo kunye neesosi, ezinomthamo ukusuka kwi-10 ukuya kwi-100 ml.Ezi phakheji nazo zinokutyiwa kwaye zilahlwe kwinkunkuma eqhelekileyo yekhaya kwaye zonakaliswe kwindawo yendalo kwiiveki ezi-6.
2) Ngaba ikhokhonathi ifayibha ingenza iingqayi zeentyatyambo?
I-Foli8, umthengisi wezityalo zombane waseBritane, uphehlelele uluhlu lweembiza zeentyatyambo ezinokubola ezenziwe nge-coconut fiber kunye ne-latex yendalo.
Esi sityalo sisekelwe kwisityalo asincedi kuphela ukunciphisa indawo yendalo, kodwa siluncedo nakwimbono yezityalo.Njengoko sonke sisazi, iimbiza ze-coconut fiber zinokukhuthaza ukukhula okunamandla kweengcambu.Olu lutsha luphinda luthintele imfuneko yokubunjwa kwakhona, njengoko ababumbi abadala banokufakwa ngokulula kwizinto ezinkulu ngelixa benciphisa ingozi yomonakalo weengcambu.
I-Foli8 ikwabonelela ngezisombululo zokutyala ishishini kwiindawo ezidumileyo zaseLondon ezifana ne-Savoy, kunye nezinye zeendawo zokusebenza eziphezulu zase-UK zehlabathi.
3) IiPopcorn njengezinto zokupakisha
Ukusebenzisa iipopcorn njengezinto zokupakisha kuvakala njengenye iqhula elidala.Nangona kunjalo, kutshanje, abaphandi kwiYunivesithi yaseGottingen baye baphuhlisa isityalo esinjalo esihambelana nokusingqongileyo njengenye indlela yokusingqongileyo kwi-polystyrene okanye iplastiki.Iyunivesithi isayine isivumelwano selayisenisi kunye ne-nordgetreide yokusetyenziswa kwezorhwebo kweenkqubo kunye neemveliso kushishino lokupakisha.
UStefan Schult, umlawuli olawulayo we-nordgetreide, uthe le phakheji isekwe kwisityalo yenye indlela elungileyo ezinzileyo.Yenziwe ngeemveliso ezingenakutyiwa eziveliswe kwi-cornflakes.Emva kokusetyenziswa, inokudityaniswa ngaphandle kwentsalela.
"Le nkqubo entsha isekelwe kubuchwephesha obuphuhliswe ngushishino lweplastiki kwaye inokuvelisa iindawo ezahlukeneyo ezibunjiweyo," kuchaza uprofesa u-Alireza kharazipour, intloko yeqela lophando.“Oku kubaluleke ngakumbi xa kuqwalaselwa ukupakishwa kuba kuqinisekisa ukuthuthwa okukhuselekileyo kweemveliso kwaye kunciphisa inkunkuma.Konke oku kuphunyezwa ngokusebenzisa imathiriyeli enokonakala emva koko.”
4) I-Starbucks isungula "umbhobho we-slag"
Njengeyona venkile inkulu yekofu yehlabathi, i-Starbucks ibisoloko iphambi kwamashishini amaninzi okutya kwindlela yokhuseleko lokusingqongileyo.I-tableware elahlayo eyenziwe ngezinto ezichithwayo ezifana ne-PLA kunye nephepha zingabonwa kwivenkile.Ngo-Epreli kulo nyaka, i-Starbucks yaphehlelela ngokusemthethweni i-biodegradable straw eyenziwe nge-PLA kunye neendawo zekofu.Kuthiwa izinga lokuthotywa kwebhayoloji lomququ lingafikelela ngaphezulu kwe-90% kwiinyanga ezine.
Ukusukela nge-22 ka-Epreli, ngaphezulu kweevenkile ezingama-850 eShanghai zikhokele ekuboneleleni lo “mbhobho we-slag” kwaye uceba ukugubungela ngokuthe ngcembe iivenkile kwilizwe liphela kulo nyaka.
5) Ibhotile yephepha edibeneyo yeCoca Cola
Kulo nyaka, uCoca Cola ukwaphehlelele ibhotile yephepha.Umzimba webhotile yephepha wenziwe ngephepha le-Nordic wood pulp, elinokuphinda lisetyenziswe nge-100%.Kukho ifilimu ekhuselayo ye-biomaterials ye-biodegradable kudonga lwangaphakathi lomzimba webhotile, kwaye i-cap cap nayo yenziwe ngeplastiki ye-biodegradable.Umzimba webhotile wamkela i-inki ezinzileyo okanye i-laser engraving, ephinda inciphisa inani lezinto eziphathekayo kwaye ihambelana kakhulu nokusingqongileyo.
Uyilo oluhlanganisiweyo luqinisa amandla ebhotile, kwaye i-design texture wrinkled yongezwa kwisiqingatha esisezantsi sebhotile ukuze ubambe kangcono.Esi siselo siya kuthengiswa kwisiseko sokulinga kwimarike yaseHungary, i-250 ml, kwaye ibhetshi yokuqala iya kukhawulelwa kwiibhotile ze-2000.
I-Coca Cola ithembise ukufezekisa i-100% yokuphinda isetyenziswe ukupakishwa ngo-2025 kwaye iceba ukuseka inkqubo ngo-2030 ukuqinisekisa ukuba ukupakishwa kwebhotile nganye okanye i-can iya kuphinda isetyenziswe.
Nangona iiplastiki ezonakalisayo zine "halo yendalo" yazo, zihlala ziphikisana kwishishini.Iiplastiki ezonakeleyo ziye zaba "yintandokazi entsha" yokutshintsha iiplastiki eziqhelekileyo.Nangona kunjalo, ukuze kuphuhliswe ngokwenene iiplastiki ezinokonakala ixesha elide, indlela yokujongana nengxaki yenzululwazi yokulahlwa kwenkunkuma eveliswa emva kokusetyenziswa okukhulu kweeplastiki ezinokonakala kuya kuba yinto ephambili ekuthinteleni uphuhliso olunempilo noluzinzileyo lweeplastiki eziguquguqukayo.Ngoko ke, ukunyuswa kweeplastiki ezichithwayo kunendlela ende yokuhamba.
