Plasic ichafanira kuputsika kuita organic zvinhu uye kabhoni dhaidhiyoni mumhepo yakavhurika mukati memakore maviri kuti ionekwe seyakaora pasi peiyo UK chiyero chitsva chiri kuunzwa neBritish Standards Institute.
Zvikamu makumi mapfumbamwe kubva muzana zvekabhoni kabhoni iri mupurasitiki inoda kushandurwa kuita kabhoni dhaibhorosi mukati memazuva mazana manomwe nemakumi matatu kuti isangane nechiyero chitsva cheBSI, icho chakaunzwa zvichitevera kuvhiringika kwezvinoreva biodegradability.
Iyo PAS 9017 yakajairwa inovhara ma polyolefins, mhuri ye thermoplastics inosanganisira polyethylene uye polypropylene, iyo inokonzeresa hafu yezvese kusvibiswa kwepurasitiki munzvimbo.
Polyolefins anoshandiswa zvakanyanya kugadzira mabhegi ekutakura, michero nemiriwo kurongedza uye mabhodhoro ekunwa.
"Kugadzirisa dambudziko repasi rose remarara epurasitiki kunoda fungidziro uye hunyanzvi," akadaro Scott Steedman, mutungamiriri wezviyero paBSI.
"Pfungwa itsva dzinoda kubvumwa, dziripo pachena, dzakazvimiririra zviyero kuti zvigadziriswe zvinovimbika neindasitiri," akawedzera, achitsanangura chiyero chitsva se "chibvumirano chekutanga chevatori vechikamu pamusoro pekuti vangayera sei biodegradability ye polyolefins iyo inomhanyisa kusimbiswa kwehunyanzvi. yeplastiki biodegradation. "
Standard inongoshanda kune ivhu-yakavakirwa kusvibiswa kwepurasitiki
PAS 9017, yakanzi Biodegradation ye polyolefins munzvimbo yakavhurika yepasi, inosanganisira kuyedza plastiki kuratidza kuti inogona kuputsika kuita wakisi isingakuvadze mumhepo.
Iyo chiyero inongoshanda kune ivhu-yakavakirwa kusvibiswa kwepurasitiki iyo, maererano neBSI, inogadzira zvikamu zvitatu muzvina zvepurasitiki inotiza.
Iyo haivhare mapurasitiki mugungwa, uko vaongorori vakawana kuti anonzi biodegradable mabhegi epurasitiki anoramba achishandiswa mushure memakore matatu.
"Sample yebvunzo ichaonekwa seyakanaka kana 90 muzana kana kupfuura yekabhoni kabhoni muwakisi ichishandurwa kuita kabhoni dhaikisaidhi panopera nguva yekuedzwa kana ichienzaniswa nekutonga kwakanaka kana zvachose," akadaro BSI.
"Nguva yakakwana yenguva yekuedzwa ichave mazuva 730."
Standard yakagadzirwa kumisa vanogadzira kutsausa veruzhinji
Gore rapfuura, pakati pekunetsekana kuti vagadziri vari kutsausa veruzhinji pakushandisa mazwi akadai se "biodegradable", "bioplastic" uye "compostable", hurumende yeUK yakadana nyanzvi kuti dzibatsire kusimudzira zviyero zvepurasitiki.
Izwi rekuti "biodegradable" rinoreva kuti chinhu chinoputsika zvisingakuvadze mumhepo, kunyangwe zvingatora mazana emakore kuti mamwe mapurasitiki adaro.

Hurumende yeUK inoenda kugumisa "zvisina kujeka uye zvinotsausa" bioplastic terminology

Bioplastic, iyo ipurasitiki inogadzirwa kubva mumidziyo mipenyu kana mhuka mhenyu, haigone kuparara. Compostable plastiki inongoputsika zvisingakuvadzi kana ikaiswa mune yakakosha composter.
PAS 9017 yakagadziridzwa neboka rinotungamira renyanzvi dzemapurasitiki uye inotsigirwa nePolymateria, kambani yekuBritain yakagadzira chinongedzo chinobvumira mapurasitiki emafuta emafuta kuti biodegrade.
Maitiro matsva akagadzirirwa kubvumira mapurasitiki kuti biodegrade
Iyo yekuwedzera inobvumira thermoplastics, iyo inopesana zvakanyanya nekudzikira, kuputsika mushure mesherufu yakapihwa ichirarama kana yaiswa mumhepo, chiedza uye nemvura pasina kuburitsa inogona kukuvadza microplastics.
Maitiro aya anoshandura yakawanda epurasitiki kuita kabhoni dhaikisaidhi, inova gasi regreenhouse.
"Tekinoroji yedu yakagadzirirwa kuve neakawanda anokonzeresa kuti ave nechokwadi che activation kwete chimwe chete," Polymateria akadaro.
"Nekudaro nguva, mwenje weUV, tembiricha, hunyoro nemhepo zvese zvinotora chikamu mumatanho akasiyana ekuita nehunyanzvi hwekuita makemikari kushandura plastiki kuita biocompatible material."
"Yakazvimirira yechitatu-bato murabhoritari kuyedzwa kwakaratidza kuti tinowana zana muzana biodegradation pamudziyo wepurasitiki wakaomarara mumazuva 336 uye zvinhu zvemufirimu mumazuva 226 mumamiriro ezvinhu epasirese, tichisiya zero microplastics kumashure kana kukonzeresa kukuvadza kwezvakatipoteredza," Polymateria. CEO Niall Dunne akaudza Dezeen.
