I-Plasic kuya kufuneka ihlehle ibe yi-organic matter kunye ne-carbon dioxide emoyeni ovulekileyo phakathi kweminyaka emibini ukuze ihlelwe njenge-biodegradable phantsi komgangatho omtsha wase-UK owaziswa yi-British Standards Institute.
Amashumi alithoba eepesenti zecarbon dioxide equlethwe kwiplastiki kufuneka iguqulwe ibe yikharbon diokside phakathi kweentsuku ezingama-730 ukuhlangabezana nomgangatho omtsha weBSI, othe waziswa emva kokubhideka ngentsingiselo yokonakaliswa kwezinto eziphilayo.
Umgangatho we-PAS 9017 ugubungela i-pololefins, intsapho ye-thermoplastics ebandakanya i-polyethylene kunye ne-polypropylene, ejongene nesiqingatha salo lonke ungcoliseko lweplastiki kwindalo.
IiPolyolefins zisetyenziswa kakhulu ukwenza iingxowa zokuthwala, ukupakishwa kweziqhamo kunye nemifuno kunye neebhotile zokusela.
"Ukujongana nomceli mngeni wehlabathi wenkunkuma yeplastiki kufuna ukucinga kunye nokuveliswa kwezinto ezintsha," utshilo uScott Steedman, umlawuli wemigangatho kwi-BSI.
"Iingcamango ezintsha kufuneka zivunyelwene, zifumaneke esidlangalaleni, imigangatho ezimeleyo ukwenzela ukuba kuhanjiswe izisombululo ezithembekileyo ngushishino," wongezelela, echaza umgangatho omtsha "njengemvumelwano yokuqala yabachaphazelekayo malunga nendlela yokulinganisa i-biodegradability ye-polyolefins eya kukhawulezisa ukuqinisekiswa kobuchwepheshe. ukwenzela ukuthotywa kweplastiki.”
Umgangatho uya kusebenza kuphela kungcoliseko lweplastiki esekwe emhlabeni
I-PAS 9017, enesihloko esithi Biodegradation of polyolefins kwindawo evulekileyo yomhlaba, ibandakanya ukuvavanya iplastiki ukubonisa ukuba inokuqhekeka ibe yi-wax engenabungozi emoyeni.
Umgangatho usebenza kuphela kungcoliseko lweplastiki esekwe kumhlaba othi, ngokutsho kwe-BSI, yenze iikota ezintathu zeplastiki ebalekayo.
Ayigubungeli iplastiki elwandle, apho abaphandi bafumanise ukuba iingxowa zeplastiki ekucingelwa ukuba zinokonakala zihlala zisebenziseka emva kweminyaka emithathu.
"Isampuli yovavanyo iya kuthathwa ivumelekile ukuba i-90 ipesenti okanye ngaphezulu kwekhabhoni ephilayo kwi-wax iguqulwa ibe yi-carbon dioxide ekupheleni kwexesha lokuvavanya xa kuthelekiswa nokulawula okulungileyo okanye ngokupheleleyo," kusho i-BSI.
"Elona xesha lilonke lexesha lovavanyo liya kuba ziintsuku ezingama-730."
Umgangatho wenziwa ukunqanda abavelisi balahlekisa uluntu
Kunyaka ophelileyo, phakathi kwenkxalabo yokuba abavelisi babelahlekisa uluntu xa besebenzisa amagama afana ne "biodegradable", "bioplastic" kunye "necompostable", urhulumente wase-UK wabiza iingcali ukuba zincede ukuphuhlisa imigangatho yeeplastiki.
Igama elithi "biodegradable" lithetha ukuba into iya kuphuka ngokungenabungozi kwimekobume, nangona kungathatha amakhulu eminyaka ukuba ezinye iiplastiki zenze oko.
Ibali eliyeleleneyo
Urhulumente wase-UK ugqiba kwelokuba aphelise isigama “esingaqondakaliyo nesilahlekisayo” se-bioplastic
I-Bioplastic, eyiplastiki eyenziwe ngezinto ezithathwe kwizityalo okanye izilwanyana eziphilayo, ayinako ukubola ngokwendalo.Iplastiki evundisiweyo iya kuphuka ngokungenabungozi ukuba ifakwe kwi-compost ekhethekileyo.
I-PAS 9017 yaphuhliswa kunye neqela elilawulayo leengcali zeplastiki kwaye ixhaswa yi-Polymateria, inkampani yaseBritani ephuhlise isongezo esivumela iiplastiki zefosili-fuel ukuba i-biodegrade.
Inkqubo entsha eyilelwe ukuvumela iiplastiki ukuba ziwohloke
I-additive ivumela i-thermoplastics, echasene kakhulu nokuthotywa, ukuba iphule emva kweshelufu enikeziweyo iphila xa ibonakaliswe emoyeni, ukukhanya kunye namanzi ngaphandle kokuvelisa i-microplastics enokuba yingozi.
Inkqubo kodwa iguqula iplastiki eninzi ibe yikharbon diokside, eyigesi yegreenhouse.
"Itekhnoloji yethu yenzelwe ukuba ibe nezinto ezininzi ezibangela ukuba kuqinisekiswe ukusebenza endaweni enye," utshilo uPolymateria.
"Ngelo xesha, ukukhanya kwe-UV, ubushushu, ukufuma kunye nomoya zonke ziya kudlala indima kwizigaba ezahlukeneyo zokusebenzisana netekhnoloji yokuguqula iplastiki ibe yinto ehambelana nebhayoloji."
"Uvavanyo oluzimeleyo lwelabhoratri yomntu wesithathu lubonise ukuba sifezekise i-100 leepesenti kwi-biodegradation kwisikhongozelo seplastiki eyomeleleyo kwiintsuku ezingama-336 kunye nemathiriyeli yefilimu kwiintsuku ezingama-226 kwiimeko zehlabathi lokwenyani, sishiya i-zero microplastics ngasemva okanye ibangela nayiphi na ingozi kwindalo," iPolymateria. I-CEO uNiall Dunne uxelele uDezeen.

Uqoqosho olujikelezayo “alunakuze lusebenze ngezinto esinazo” utsho uCyrill Gutsch weParley yeeLwandle
Ngemveliso yeplastiki elindeleke ukuba iphindeke kabini ngo-2050, abaninzi abayili baphonononga ezinye iindlela kwiiplastiki ezisekwe kwifosili.
UPriestman Goode kutshanje wenze ukupakishwa kokutya okukhawulezayo okuphinda kusetyenziswe ukusuka kumaqokobhe eembotyi zekoko, ngelixa iBottega Veneta iyile ibhuthi enokubola eyenziwe ngommoba kunye nekofu.
Imbasa kaJames Dyson yalo nyaka e-UK yaphunyelelwa ngoyilo olubamba ukukhutshwa kwe-microplastic ephuma kumavili emoto, engomnye wemithombo emikhulu yongcoliseko lweplastiki.
