I-Plasic kuyodingeka ihlehle ibe izinto eziphilayo kanye ne-carbon dioxide emoyeni ovulekile phakathi neminyaka emibili ukuze ifakwe esigabeni njenge-biodegradable ngaphansi kwezinga elisha lase-UK elethulwa yi-British Standards Institute.
Amaphesenti angamashumi ayisishiyagalolunye ekhabhoni ephilayo equkethwe kupulasitiki idinga ukushintshwa ibe isikhutha zingakapheli izinsuku ezingama-730 ukuze ihlangabezane nezinga elisha le-BSI, elethulwe kulandela ukudideka ngencazelo yokuwohloka kwezinto eziphilayo.
Izinga le-PAS 9017 lihlanganisa i-polyolefins, umndeni we-thermoplastics ohlanganisa i-polyethylene ne-polypropylene, okuyiwona obhekene nengxenye yakho konke ukungcoliswa kwepulasitiki emvelweni.
Ama-Polyolefin asetshenziswa kakhulu ukwenza izikhwama zokuphatha, izithelo nemifino kanye namabhodlela eziphuzo.
“Ukubhekana nenselelo yomhlaba wonke yokulahlwa kwepulasitiki kudinga umcabango kanye nokusungulwa kwezinto ezintsha,” kusho uScott Steedman, umqondisi wezindinganiso kwa-BSI.
"Imibono emisha idinga ukuvunyelwana, etholakala esidlangalaleni, izindinganiso ezizimele zokunikeza amandla ukulethwa kwezixazululo ezithenjwa yimboni," wanezela, echaza izinga elisha "njengemvumelwano yokuqala yababambe iqhaza mayelana nendlela yokukala ukubola kwe-polyolefin okuzosheshisa ukuqinisekiswa kobuchwepheshe. ukuze kucekelwe phansi ipulasitiki.”
Izinga lizosebenza kuphela ekungcolisweni kwepulasitiki okusekelwe emhlabathini
I-PAS 9017, enesihloko esithi Biodegradation of polyolefins endaweni evulekile yasemhlabeni, ihlanganisa ukuhlola ipulasitiki ukufakazela ukuthi ingaphuka ibe ingcina engenabungozi emoyeni.
Izinga lisebenza kuphela ekungcolisweni kwepulasitiki okusekelwe emhlabeni, ngokusho kwe-BSI, okwenza izingxenye ezintathu kwezine zepulasitiki ebalekile.
Ayifaki ipulasitiki olwandle, lapho abacwaningi bethole khona ukuthi izikhwama zepulasitiki okuthiwa zingabola zihlale zisebenziseka ngemva kweminyaka emithathu.
"Isampula yokuhlola izothathwa njengevumelekile uma amaphesenti angu-90 noma ngaphezulu ekhabhoni ephilayo ku-wax eguqulwa abe yi-carbon dioxide ekupheleni kwesikhathi sokuhlola uma kuqhathaniswa nokulawula okuhle noma ngokuphelele," kusho i-BSI.
"Isikhathi esiphelele sesikhathi sokuhlolwa kuzoba yizinsuku ezingama-730."
Okujwayelekile kudalwe ukumisa abakhiqizi abadukisa umphakathi
Ngonyaka odlule, phakathi kokukhathazeka ngokuthi abakhiqizi babedukisa umphakathi lapho besebenzisa amagama anjengokuthi "i-biodegradable", "i-bioplastic" nethi "compostable", uhulumeni wase-UK wacela ochwepheshe ukuthi basize ekuthuthukiseni izindinganiso zepulasitiki.
Igama elithi “biodegradable” lisikisela ukuthi into izophuka ngokungenabungozi endaweni ezungezile, nakuba kungase kuthathe amakhulu eminyaka ukuba amanye amapulasitiki enze kanjalo.

Uhulumeni wase-UK uthatha isinyathelo sokuqeda amagama “angaqondakali nadukisayo” we-bioplastic

I-Bioplastic, eyipulasitiki eyenziwe ngezinto ezithathwe ezitshalweni eziphilayo noma ezilwaneni, ayiboli ngokwemvelo.Ipulasitiki ehlanganiswe ne-compostable izophuka kuphela ngokungenabungozi uma ifakwe ku-compost ekhethekile.
I-PAS 9017 yathuthukiswa neqembu eliqondisayo lochwepheshe bepulasitiki futhi ixhaswe yiPolymateria, inkampani yaseBrithani esungule isithasiselo esivumela amapulasitiki aphehla uphethiloli ukuthi amosheke.
Inqubo entsha yakhelwe ukuvumela amapulasitiki ukuthi amosheke
Isengezo sivumela ama-thermoplastics, amelana kakhulu nokuwohloka, ukuba aphule ngemva kokuba ishalofu elinikeziwe liphila lapho livezwe emoyeni, ukukhanya namanzi ngaphandle kokukhiqiza ama-microplastic angaba yingozi.
Le nqubo nokho iguqula ingxenye enkulu yepulasitiki ibe isikhutha, okuyigesi ebamba ukushisa.
"Ubuchwepheshe bethu buklanyelwe ukuthi bube nezimbangi eziningi zokuqinisekisa ukusebenza kunokuba kube nesisodwa nje," kusho uPolymateria.
Ngaleso sikhathi, ukukhanya kwe-UV, izinga lokushisa, umswakama nomoya konke kuzodlala indima ezigabeni ezihlukene zokusebenzisana nobuchwepheshe ukuze kuguqulwe ipulasitiki ibe into ehambisana ne-biocompatible.”
"Ukuhlolwa kwaselabhorethri okuzimele kukhombisile ukuthi sifinyelela ku-100% we-biodegradation esitsheni sepulasitiki esiqinile ezinsukwini ezingama-336 kanye nezinto zefilimu ezinsukwini ezingama-226 ezimeni zangempela zomhlaba, sishiya ama-microplastics angekho ngemuva noma sidale noma yikuphi ukulimala kwemvelo," i-Polymateria. Isikhulu esiphezulu uNiall Dunne sitshele uDezeen.

Ngokukhiqizwa kwepulasitiki okulindeleke ukuthi kuphindwe kabili ngo-2050, abaklami abaningi bahlola ezinye izindlela zamapulasitiki asekelwe ezintweni ezimbiwa phansi.
