Pulasitiki iyenera kusweka kukhala organic zinthu ndi mpweya woipa panja pasanathe zaka ziwiri kuti iwoneke ngati yosawonongeka malinga ndi mulingo watsopano waku UK womwe ukuyambitsidwa ndi British Standards Institute.
Maperesenti makumi asanu ndi anayi pa 100 aliwonse a organic carbon omwe ali mu pulasitiki akuyenera kusinthidwa kukhala mpweya woipa mkati mwa masiku 730 kuti akwaniritse muyeso watsopano wa BSI, womwe wakhazikitsidwa potsatira chisokonezo pa tanthauzo la biodegradability.
Muyezo wa PAS 9017 umakwirira ma polyolefins, banja la thermoplastics lomwe limaphatikizapo polyethylene ndi polypropylene, zomwe zimapangitsa theka la kuipitsidwa kwa pulasitiki m'chilengedwe.
Ma polyolefin amagwiritsidwa ntchito kwambiri kupanga zikwama zonyamulira, zonyamula zipatso ndi masamba ndi mabotolo akumwa.
"Kuthana ndi vuto lapadziko lonse la zinyalala za pulasitiki kumafuna kulingalira ndi luso," anatero Scott Steedman, mkulu wa miyezo ku BSI.
"Malingaliro atsopano ayenera kuvomerezedwa, omwe akupezeka poyera, odziyimira pawokha kuti athe kubweretsa mayankho odalirika ndi makampani," adawonjezeranso, pofotokoza muyezo watsopanowu ngati "mgwirizano woyamba wa omwe akukhudzidwa nawo momwe angayezere kuwonongeka kwa polyolefins komwe kumathandizira kutsimikizira kwaukadaulo. za kuwononga pulasitiki.”
Muyezo udzangogwira ntchito pakuyipitsidwa kwa pulasitiki yochokera kumtunda
PAS 9017, yotchedwa Biodegradation of polyolefins pamalo otseguka padziko lapansi, imaphatikizapo kuyesa pulasitiki kutsimikizira kuti imatha kusweka kukhala sera yopanda vuto panja.
Muyezowu umangokhudza kuipitsidwa kwa pulasitiki kochokera kumtunda komwe, malinga ndi BSI, kumapanga magawo atatu mwa magawo atatu a pulasitiki othawa.
Simaphimba pulasitiki m'nyanja, komwe ofufuza apeza kuti matumba apulasitiki omwe amati ndi owonongeka amatha kugwiritsidwa ntchito pakatha zaka zitatu.
"Chitsanzo choyesera chidzawoneka chovomerezeka ngati 90 peresenti kapena yaikulu ya carbon organic mu sera imasandulika kukhala carbon dioxide kumapeto kwa nthawi yoyesera poyerekeza ndi kulamulira kwabwino kapena mtheradi," inatero BSI.
"Nthawi yokwanira yoyeserera ikhala masiku 730."
Standard idapangidwa kuti ayimitse opanga kusokeretsa anthu
Chaka chatha, pakati pa nkhawa kuti opanga akusocheretsa anthu pogwiritsa ntchito mawu monga "biodegradable", "bioplastic" ndi "compostable", boma la UK linapempha akatswiri kuti athandize kukhazikitsa miyezo ya pulasitiki.
Mawu akuti “biodegradable” amatanthauza kuti zinthu zimatha kuwonongeka popanda vuto lililonse m’chilengedwe, ngakhale kuti zingatenge zaka mazana ambiri kuti mapulasitiki ena atero.

Boma la UK likufuna kuthetsa mawu oti "osamveka komanso osocheretsa" a bioplastic

Bioplastic, yomwe ndi pulasitiki yopangidwa kuchokera kuzinthu zotengedwa ku zomera kapena nyama zamoyo, sichitha kuwonongeka.Mapulasitiki opangidwa ndi kompositi amangowonongeka popanda vuto ngati atayikidwa mu kompositi yapadera.
PAS 9017 idapangidwa ndi gulu lowongolera la akatswiri apulasitiki ndipo mothandizidwa ndi Polymateria, kampani yaku Britain yomwe yapanga zowonjezera zomwe zimalola kuti mapulasitiki amafuta amafuta aziwonongeka.
Njira yatsopano yopangira kuti mapulasitiki awonongeke
Chowonjezeracho chimalola ma thermoplastics, omwe amalimbana kwambiri ndi kuwonongeka, kusweka pambuyo pa alumali yopatsidwa kukhala ndi mpweya, kuwala ndi madzi popanda kupanga ma microplastic omwe angakhale ovulaza.
Njirayi imatembenuza pulasitiki yambiri kukhala mpweya woipa, womwe ndi mpweya wowonjezera kutentha.
"Tekinoloje yathu idapangidwa kuti ikhale ndi zoyambitsa zingapo kuti zitsimikizire kuyambitsa osati chimodzi," adatero Polymateria.
"Ndiye nthawi, kuwala kwa UV, kutentha, chinyezi ndi mpweya zonse zitenga mbali zosiyanasiyana kuti zigwirizane ndi ukadaulo wopanga mankhwala kuti pulasitiki ikhale chinthu chogwirizana."
"Kuyesa kodziyimira pawokha kwa labotale ya gulu lachitatu kwawonetsa kuti takwanitsa 100 peresenti pa chidebe cha pulasitiki cholimba m'masiku 336 ndi zinthu zamakanema m'masiku 226 muzochitika zenizeni, kusiya ma microplastics kumbuyo kapena kuwononga chilengedwe," Polymateria. CEO Niall Dunne adauza a Dezeen.

Chuma chozungulira "sichidzagwira ntchito ndi zida zomwe tili nazo" akutero Cyrill Gutsch wa Parley for the Oceans.

Ndi kupanga pulasitiki kukuyembekezeka kuwirikiza kawiri pofika 2050, opanga ambiri akufufuza njira zina zopangira mapulasitiki opangidwa ndi zinthu zakale.
Priestman Goode posachedwapa adapanga zoikamo chakudya chofulumira kuchokera ku zipolopolo za nyemba za koko, pomwe Bottega Veneta adapanga nsapato yowola yopangidwa ndi nzimbe ndi khofi.
Mphotho ya chaka chino ya James Dyson ku UK idapambanidwa ndi mapangidwe omwe amajambula mpweya wa microplastic kuchokera ku matayala agalimoto, omwe ndi amodzi mwamagwero akulu akuipitsa pulasitiki.
Werengani zambiri:
Mapangidwe okhazikika
 Pulasitiki
 Kupaka
Nkhani
Zinthu zomwe zimatha kuwonongeka
