Biodegradable nguo yepurasitiki yepurasitiki bhegi

Iyo compostable bag yehupenyu ndeye:
Kugadzirwa: Starch Starch inobviswa kubva pazvinhu zvisina kufanira, polymer yakasikwa inowanikwa kubva kuchibage, iyo gorosi kana mbatatisi.
Ipapo microorganismms inoshandura mumarara madiki eiyo lactic acid iyo inoshanda sechigadziko chekugadzirwa kwemaketani ePolylactic acid.
Maketeni ekuyambuka ePolymeric of the polylactic acid inopa nzvimbo kune biodegradable pepa rinoshanda sechigadzirwa chekusimudzira kwezvigadzirwa zvepurasitiki.
Iyi pepa repurasitiki inotakurwa kuenda kumakambani ekugadzira uye shanduko yemabhegi epurasitiki.
Ipapo vanogoverwa kune zvigadzirwa zvekutengesa zvekushandisa uye kutengeserana kwemabhegi anoshamisa muhupenyu hwavo hwezuva nezuva.
Bhegi rinoshandiswa uye rinobva rave dombo (rinofungidzirwa nguva yekushandisa: gumi nemaviri maminitsi)
Maitiro e biodergradation anova nguva inofungidzirwa kubva kune matanhatu kusvika ku9 mwedzi.
Iyo Bioplastics inobviswa kubva kune chibage starch yave kusingaperi uye inovandudza hupenyu, inovhara hupenyu hwekurima, kukurudzira kukura kwezana uye kunoita kuti uwedzere kusimba kwezvirimwa mu nzira yekukanda mapfumo pasi. Muzviitiko zvese zvehupenyu hwekutenderera, vamiririri vekusvibiswa vane kuderera kusvikira iyo 1000% mukuenzanisa nemaitiro epurasitiki bhegi rekugadzira.
Kunyanya kufanana kwehombodo inoshamisika ndeyekuti ivo vanogona kushandiswa sevha yezvirimwa zvepamba, uye nazvo zvinoita kuti vakure hutano uye vachikurudzira kudzoreredzwa kwemabhegi epurasitiki. Nemabhegi emabhegi ekugadzira, kunze kwekugadzira kushandiswazve
Avhareji yemunhu anoshandisa kabhegi epurasitiki yakajairika sepfupi kwenguva yakareba kunge maminitsi gumi nemaviri asati aikanda kunze, haambokufunga kuti kwaizopera kupi.
Zvakangodaro zvakaverengerwa kuwanda, iyo Standard Grocery Store Tote inotora mazana kana zviuru zvemakore kuputsa - zvakanyanya kupfuura hupenyu hwevanhu. Mabhegi anogadzira huwandu hwemapurasitiki hwakawanikwa muWhale dumbu kana eshiri matendere, uye hazvishamisi - pasi rose, isu titangei trillion mapurasitiki emadhora gore rega rega.
Bhegi rezvikwama mapurasitiki emapurasitiki anotengeswa secomputer eco-hushamwari mhinduro, anokwanisa kuputsa mune zvisina kukuvadza zvinhu nekukurumidza kupfuura zvetsika zvetsika. Imwe kambani inoti yavo yekutenga bhegi "ichashatisa uye biodegrade mune inoenderera, isingachinjiki uye isingadzoreki maitiro" kana ikapera semarara munharaunda.
Mune chidzidzo chakaburitswa vhiki ino muSainzi Science uye tekinoroji, vaongorori vakaisa vanofungidzirwa eco-hushamwari mabhegi akagadzirwa kubva kune akasiyana-siyana organic uye epurasitiki zvinhu uye anowanikwa kubva kuUK zvitoro kune muyedzo. Mushure memakore matatu kuvigwa mutiru ivhu, rakanyungudutswa mumvura yegungwa, rakajekeswa kujekesa uye mhepo kana rakarambidzwa mumabhegi, hapana kana imwe yemabhegi akapunzika munzvimbo dzese.
Kutsigirwa
Muchokwadi, mabhegi e biodeble aive akasiyiwa pasi pemvura mune marina aigona kuramba akazara mutoro wezvitoro.
"Ndeipi basa revamwe izvi chaizvo uye ruchiriyo bhodhi?" Akabvunza Richard Thompson, biologist yemugungwa kubva kuYunivhesiti yePlymouth uye munyori wezvekudzidza. Iyo polymer ndiyo tambo inodzokorora yemakemikari inogadzira chimiro chemapurasitiki, ingave biodegradable kana synthetic.
"Ivo vari kunetsa kudzokorodza uye vanononoka kusvibisa kana vachinge vava marara munharaunda,
Izvo vaongorori vakaitei
Vaongorori vakaunganidza samples dzemhando shanu dzemabhegi epurasitiki.
Iyo yekutanga mhando yakagadzirwa neyakakwira-density polyethylene - iyo yepurasitiki yakawanikwa mumabhegi echitoro. Yakanga ichishandiswa sekuenzanisa kwemamwe mana mabhegi akanyorwa seco-hushamwari:
Bhegi rezvipurasitiki rakapetwa rakagadzirwa muchikamu kubva kuOyters Shells
Marudzi maviri emabhegi akagadzirwa kubva kune oxo-biodegradable plastiki, iyo ine zvinowedzera izvo makambani anoti anobatsira kuputsa kuputsa nekukurumidza
Bhegi rinonyanya kugadzirwa rakagadzirwa kubva pazvinhu zvigadzirwa
Imwe neimwe bhegi mhando yakaiswa mune ina nharaunda. Mabhegi ese uye mabhegi akachekwa mumatanho akavigwa mubindu renyama, rakanyudzwa mumvura yemunyu mune yemasikati, kana kuvhurika mumudziyo werima mune tembiricha-inodzorwa-tembiricha lab.
Oxygen, tembiricha uye mwenje zvese zvinoshandura chimiro chevapurasitiki polastic, polymer chemist kubva kuNorthwestern University, uyo aisabatikana muchidzidzo ichi. Nekudaro zvakare inogona kuita nemvura uye yekudyidzana nemabhakitiriya kana mamwe marudzi ehupenyu.
Izvo zvasawanikwa nesainzi
Kunyangwe munzvimbo yakaoma yemugungwa, apo Algae uye mhuka dzakakurumidza kufukidza iyo mapurasitiki, makore matatu haisati yaparara chero mapurasitiki kunze kwechirimwa-chakavakirwa pasi pemvura mukati memwedzi mitatu. Mabhegi ezvekutorwa, akanyarara asi akasiya simba paakavigwa pasi pegadheni ivhu nemwedzi makumi maviri nemana.
Kurapa chete kwakapwanya mabhegi ese ezvikwama zvese kwaive pachena kwemhepo inodarika mwedzi mipfumbamwe, uye mune iyo mwero wechinyakare, bhegi rePolyethylehy, bhegi remwedzi isati yapera mwedzi 18 vasati apfuura.
