Balaasku waa in uu u kala jabaa walxaha organic iyo kaarboon laba ogsaydh hawada furan laba sano gudahood si loogu kala saaro mid noolayn kara iyada oo la raacayo halbeeg cusub oo UK ah oo uu soo bandhigayo Machadka Heerarka Ingiriiska.
Boqolkiiba sagaashan kaarboonka dabiiciga ah ee ku jira caaggu waxa ay u baahan yihiin in loogu beddelo kaarboon laba ogsaydh 730 maalmood gudahood si ay u buuxiyaan heerka cusub ee BSI, kaas oo la soo saaray ka dib markii lagu jahawareeray macnaha nooledegradability.
Heerka PAS 9017 wuxuu daboolayaa polyolefins, qoys heerkulbeegyo ah oo ay ku jiraan polyetylen iyo polypropylene, kuwaas oo mas'uul ka ah kala badh dhammaan wasakhowga caagga ah ee deegaanka.
Polyolefins ayaa si weyn loogu isticmaalaa in lagu sameeyo bacaha sidayaasha, baakadaha khudradda iyo khudradda iyo dhalooyinka la cabbo.
"La-dagaallanka caqabada caalamiga ah ee qashinka caagga ah waxay u baahan tahay male-awaal iyo hal-abuurnimo," ayuu yiri Scott Steedman, maamulaha heerarka BSI.
"Fikradaha cusubi waxay u baahan yihiin in la heshiiyo, si guud loo helo, heerar madax-bannaan si ay awood ugu siiso bixinta xalalka la isku halleyn karo ee warshadaha," ayuu raaciyay, isagoo ku sifeeyay heerka cusub "isku dhafka ugu horreeya ee daneeyayaasha ee sida loo cabbiro biodegradaability of polyolefins taas oo dardargelin doonta xaqiijinta tignoolajiyada loogu talagalay bayoolajieynta balaastikada ah."
Heerarka waxa kaliya oo lagu dabaqi doonaa wasakhowga caagga ah ee dhulka ku salaysan
PAS 9017, oo cinwaankeedu yahay Biodegradation of polyolefins ee jawiga hawada furan, waxay ku lug leedahay tijaabinta balaastiga si loo caddeeyo inay u jajabi karto dhux aan waxyeello lahayn hawada furan.
Halbeeggu waxa uu khuseeyaa wasakhowga balaastigga ah ee dhulka kaas oo, marka loo eego BSI-da, ka kooban saddex-meelood meel caag baxsad ah.
Kuma daboosho balaastiigga badda, halkaas oo cilmi-baarayaashu ay ogaadeen in bacaha bacaha ah ee la malaynayo inay sii ahaanayaan kuwo la isticmaali karo saddex sano ka dib.
"Muunada tijaabada ah waxaa loo aqoonsan doonaa mid ansax ah haddii boqolkiiba 90 ama ka badan kaarboonka organic ee dhuka ku jira loo beddelo kaarboon laba ogsaydh dhammaadka muddada tijaabada marka la barbar dhigo kantaroolka togan ama gebi ahaanba," ayay tidhi BSI.
"Waqtiga ugu badan ee wakhtiga imtixaanku waa inuu noqdaa 730 maalmood."
Heerarka loo sameeyay si loo joojiyo soosaarayaasha marin habaabinta dadweynaha
Sannadkii hore, iyada oo ay jirto walaac laga qabo in wax-soo-saarayaashu ay marin habaabiyaan dadweynaha marka ay isticmaalayaan ereyo ay ka mid yihiin "biodegradable", "bioplastic" iyo "compostable", dawladda UK waxay ku baaqday khubaro inay ka caawiyaan horumarinta heerarka caagadaha.
Erayga “biodegradable” waxa uu tusinayaa in shaygu si aan dhib lahayn ugu burburi doono deegaanka, inkasta oo ay qaadan karto boqollaal sano in balaastikada qaar ay sidaas sameeyaan.

Dawladda UK waxay u dhaqaaqday sidii ay u joojin lahayd erey-bixinnada bioplastic-ka "aan caddayn iyo marin-habaabin".
Bioplastic, oo ah balaastiig laga sameeyay maaddooyinka laga helo dhirta nool ama xayawaanka, ma aha mid si dabiici ah u noolayn karo.Balaastii la qasi karaa waxay si dhib la'aan u burburi doontaa haddii lagu dhejiyo composter gaar ah.
PAS 9017 waxaa lagu sameeyay koox isteerin ah oo khubaro balaastikada ah waxaana kafaala qaaday Polymateria, oo ah shirkad Ingiriis ah oo soo saartay wax lagu daro taasoo u ogolaanaysa balaastiig-fuelka inay hoos u dhacaan.
Nidaam cusub oo loogu talagalay in loogu oggolaado balaastiigga inay biodegrade-gareeyaan
Wax-ku-darku wuxuu u oggolaanayaa heerkulbeegyada, kuwaas oo aadka u adkaysan kara nabaad-guurka, inay burburaan ka dib marka shelf la siiyay ay noolaadaan marka ay soo gaadhaan hawada, iftiinka iyo biyaha iyada oo aan la soo saarin microplastics khatar ah.
Hawshu si kastaba ha ahaatee, inta badan balaastiigga waxay u beddeshaa kaarboon dioxide, taas oo ah gaaska aqalka dhirta lagu koriyo.
"Tiknoolajiyadayada waxaa loogu talagalay in ay yeelato kiciyeyaasha badan si loo hubiyo firfircoonida halkii ay ka ahaan lahayd hal keliya," Polymateria ayaa tiri.
"Waqtigan xaadirka ah, iftiinka UV, heerkulka, qoyaanka iyo hawada ayaa dhamaantood door ka ciyaari doona marxalado kala duwan si ay ula falgalaan tignoolajiyada si ay kiimikadu u beddesho caagaga wax ku habboon noolaha."
"Tijaabada shaybaarka madax-bannaan ee qolo saddexaad ayaa muujisay inaan ku guuleysanay 100 boqolkiiba biodegradation weel caag ah oo adag gudaha 336 maalmood iyo walxaha filimka ee 226 maalmood ee xaaladaha dhabta ah, ka tagista eber microplastics ama keenaya waxyeello deegaanka ah ee habka," Polymateria Maamulaha guud ee Niall Dunne ayaa u sheegay Dezeen.

Iyada oo la filayo in wax soo saarka caaggu uu labanlaabo 2050, naqshadeeyayaal badan ayaa sahaminaya beddelka caagadaha fosil-ku-saleysan.
Wadaadka Goode ayaa dhawaan sameeyay baakado cunto degdeg ah dib loo isticmaali karo oo laga sameeyay qolofka digirta kookaha, halka Bottega Veneta ay nashqadaysay kabo noole noolayn kara oo laga sameeyay sonkorta iyo kafeega.
Abaalmarinta James Dyson ee UK ee sanadkan waxa ku guulaystay naqshad soo saarta qiiqa yar-yar ee taayirada baabuurta, kuwaas oo ka mid ah meelaha ugu waaweyn ee wasakhowga caagga ah ka dhasha.
