I-plasic kuzofanela yehle ibe yinto e-organic dioxide emoyeni ovulekile kungakapheli iminyaka emibili ukuze ihlukaniswe njenge-biodegradable ngaphansi kwesikhungo esisha sase-UK esekwe yiBritish Standards Institute.
Amaphesenti angamashumi ayisishiyagalolunye amaphesenti e-organic carbon aqukethwe ngopulasitiki azoguqulwa abe yi-carbon dioxide kungakapheli izinsuku ezingama-730 ukufeza i-BSI ejwayelekile, eye yethulwe ngokulandela ukudideka ngencazelo ye-biodegracating.
Ama-pollolefins ajwayelekile we-PAS 9017 ama-polyolefins ajwayelekile, umndeni wama-thermoplastics afaka i-polyethylene ne-polypropylene, enesibopho sokungcoliswa kwepulasitiki emvelweni.
Ama-polyolefins asetshenziswa kabanzi ukwenza izikhwama zethrekhi, izithelo kanye nokupakishwa kwemifino namabhodlela okuphuza.
"Ukubhekana nenselelo yomhlaba wonke yokungcola kwepulasitiki kudinga ukucabanga nokuqamba izinto ezintsha," kusho uScott Steedman, umqondisi wamazinga eBSI.
"Imibono emisha idinga amazinga avunyelwe, atholakala esidlangalaleni, ukuvumela ukulethwa kwezixazululo ezithembekile ezenziwa emkhakheni," engeza, ukuvumelanisa okusha njenge-biodergadability okuzosheshisa ubuchwepheshe be-biodegradadation yepulasitiki. "
I-Standard izosebenza kuphela ekungcoleni kwepulasitiki okususelwa kumhlaba
I-PAS 9017, i-biodegradation enesihloko esithi Pollolefins emvelweni evulekile ye-air-air Terrestrial Emvelweni, ifaka ukuhlola ipulasitiki ukufakazela ukuthi ingahle idilize ibe yi-wax engenangozi emoyeni ovulekile.
Izinga lisebenza kuphela ekungcoleni kwepulasitiki okususelwa kumhlaba, ngokusho kwe-BSI, kwenza izingxenye ezintathu zepulasitiki ezibalekayo.
Akumbozi ngeplastiki olwandle, lapho abacwaningi bathole ukuthi izikhwama zepulasitiki ezihlangene zihlala zisebenza ngemuva kweminyaka emithathu.
"Isampula yokuhlola izothathwa njenge-acculis uma amaphesenti angama-90 noma ngaphezulu kwekhabhoni ye-organic ku-wax iguqulwa ibe yi-carbon dioxide ngasekupheleni kwesikhathi sokuhlola uma kuqhathaniswa ngokuphelele," kusho i-BSI.
"Isikhathi esiphezulu sesikhathi sokuhlola sizoba izinsuku ezingama-730."
Okujwayelekile okwenzelwe ukumisa abakhiqizi abadukisa umphakathi
Ngonyaka owedlule, ukukhathazeka phakathi kwalapho abakhiqizi bebedukisa umphakathi lapho besebenzisa imigomo efana ne- "biodegradable", "bioplastic", "i-bioplastic", uhulumeni wase-UK wacela ukuthi akwenze amazinga wepulasitiki.
Igama elithi "biodegradable" lisho ukuthi izinto ezibonakalayo zizodiliza ngokungenangozi emvelweni, yize kungathatha amakhulu eminyaka ukuthola amapulasitiki athile enze njalo.

Uhulumeni wase-UK ushukumisela ukuqeda "okucacile nokudukisa igama elithi" bioplastic terminology

I-Bioplastic, enziwe ngopulasitiki kusuka ezintweni ezithathwe ezitshalweni eziphilayo noma ezilwaneni, akulona iqiniso lemvelo. Ipulasitiki ekhokhwayo izodiliza kuphela ngokungenangozi uma ibekwe kwi-compors ekhethekile.
I-PAS 9017 yathuthukiswa neqembu eliqondisa ochwepheshe be-plastics futhi ixhaswe yi-polymateria, inkampani yaseBrithani eye yakha isengezo esivumela amapulasithi we-biossil-fuel e-biodeGrade.
Inqubo entsha yenzelwe ukuvumela amapulasitiki e-biodegrade
Isengezo ivumela ama-thermoplastics, amelana kakhulu nokonakaliswa, ukwehla ngemuva kweshalofu elinikeziwe bukhoma lapho kuvezwa umoya, ukukhanya namanzi ngaphandle kokukhiqiza ama-microplastics angaba yingozi.
Inqubo nokho iguqula iningi lepulasitiki libe yikhabhoni diokside, okuyi-greenhouse kagesi.
"Ubuchwepheshe bethu benzelwe ukuba nezimbangela eziningi ukuqinisekisa ukusebenza kusebenze kunokuba nje," kusho uPolmateria.
"Ngakho-ke, isikhathi, ukuKhanya kwe-UV, izinga lokushisa, umswakama nomoya kuzodla indima ngezigaba ezahlukahlukene ukuze zihlanganyele nobuchwepheshe bokuguqula ipulasitiki elihambisanayo."
"Ukuhlolwa kwelabhorethri okuzimele kwalesi sigameko kubonise ukuthi sifinyelela i-biodegradadation eyi-100 pent bioder yepulasitiki ngezinsuku ezingama-336 kanye nezinto zefilimu ngezinsuku ezingama-226," kudala noma yikuphi ukulimala kwemvelo kwinqubo.

Ngokukhiqizwa kwepulasitiki okulindeleke ukuthi kuphindeka kabili ngo-2050, abaklami abaningi bahlola ezinye izindlela zomabalazi basemanzini basemanzini.
Umpristi Goode usanda kudalulwa okusheshayo kokudla okuvela kuma-cocoa bean shells, kuyilapho i-bottega veneta yakhelwe i-biodergradable boot eyenziwe ngomoba nekhofi.
UJames Dyson Award e-UK wanqotshwa umklamo odonsa ama-microplastic ukuphuma kwamathayi emoto, okungomunye wemithombo emikhulu yokungcoliswa kwepulasitiki.
