Biodegradable Garment Plastic Bag

Iyo compostable bag lifecycle ndeye:
Kugadzirwa: iyo starch yechibage inotorwa kubva kune yakabikwa, yakasikwa polymer inowanikwa kubva kune chibage starch, gorosi kana mbatatisi.
Ipapo ma microorganisms anoashandura kuita molecule diki yelactic acid inoshanda sehwaro hwekugadzirwa kwepolymer cheni yepolylactic acid.
Macheni akachinjika epolymeric epolylactic acid anopa nzvimbo kune biodegradable plastic sheet iyo inoshanda sehwaro hwekutsanangudza kwezvizhinji zvisingasvibise zvigadzirwa zvepurasitiki.
Iri pepa repurasitiki rinotakurwa kumakambani ekugadzira uye shanduko yemabhegi epurasitiki.
Zvadaro vanozogoverwa kune mabhizimisi ekushandisa uye kutengeserana kwemabhegi anogadzirwa necompostable muhupenyu hwavo hwezuva nezuva.
Bhegi rinoshandiswa uye rinobva rava dongo (inofungidzirwa nguva yekushandisa: maminitsi gumi nemaviri)
Iyo nzira ye biodegradation inova iyo inofungidzirwa nguva kubva kumwedzi mitanhatu kusvika kupfumbamwe.
Iyo bioplastics yakatorwa kubva muchibage starch yave isingaperi uye inogona kuvandudzwa, inopa hupenyu hupfupi uye hwakavharika sehuwandu hwekurima kukuru, kushandisa mvura shoma, kukurudzira kukura kwechikamu chechirimwa uye inosimbisa kuwedzera kwezvirimwa muminda. nzira yekurega.Mukuita kwese kutenderera kwehupenyu, vamiririri vekusvibisa vadzikira kusvika 1000% mukuenzanisa nemaitiro ekugadzirwa kwebhegi repurasitiki.
Hunhu hweCompostable bag nderekuti dzinogona kushandiswa sefetiraiza yezvirimwa zvemumba, uye nazvo zvinoita kuti zvikure zvine hutano uye zvinokurudzira kushandiswazve kwemasaga epurasitiki.Nemasaga eAMS Compostables, kunze kwekugadzirazve kuraswa, zvinodzivirirwa kuunganidza marara asina kufanira kunzvimbo dzehutsanana uye kuderedza kutsvikinyidzana kwemarara nechinangwa chekuvandudza mamiriro ehutano hweveruzhinji munharaunda nenharaunda.
Wepakati munhu anoshandisa bhegi repurasitiki rakajairwa kwenguva pfupi semaminitsi gumi nemaviri asati airasa, asingambofungi nezvekuti angagumira kupi.
Asi kana yangoendeswa kunzvimbo yekurasira ivhu, iyo yakajairwa girosari tote inotora mazana kana zviuru zvemakore kuti iparare - zvakanyanya kupfuura hupenyu hwemunhu.Mabhegi anoumba huwandu hunotyisa hwepurasitiki inowanikwa mumatumbu ewhale kana matendere eshiri, uye hazvishamisi - pasi rose, tinoshandisa pakati pe1 kusvika 5 trillion mabhegi epurasitiki gore rega.
Biodegradable epurasitiki mabhegi anotengeswa seakawanda eco-hushamwari mhinduro, anokwanisa kuputsika kuita zvinhu zvisingakuvadzi nekukurumidza kupfuura mapurasitiki echinyakare.Imwe kambani inoti bhegi ravo rekutenga "richadzikisira uye kusvibisa zvipenyu nenzira inoenderera, isingadzokerike uye isingamisikike" kana zvikaguma zvaita marara munharaunda.
Muchidzidzo chakaburitswa svondo rino muEnvironment Sayenzi neTekinoroji, vaongorori vakaisa mabhegi anofungidzirwa kuti ane hushamwari akagadzirwa kubva akasiyana organic uye epurasitiki zvinhu uye akatorwa kubva kuUK zvitoro kuti aedzwe.Mushure memakore matatu akavigwa muvhu rebindu, rakanyudzwa mumvura yegungwa, rakavhurika chiedza nemhepo kana kuvharirwa murabhoritari, hapana kana masaga akaputsika zvachose munzvimbo dzese.

Muchokwadi, mabhegi anoodzeka akange asara ari pasi pemvura mumarina aigona kuramba akatakura girosari rakazara.
"Ndeipi basa remamwe mapolymer aya ane hunyanzvi?"akabvunza Richard Thompson, nyanzvi yezvinyorwa zvegungwa kubva kuYunivhesiti yePlymouth uye munyori mukuru wekudzidza.Polymer iketani inodzokororwa yemakemikari anoumba chimiro chepurasitiki, ingave biodegradable kana synthetic.
"Ivo vane dambudziko rekugadzirisa zvakare uye vanononoka kusvibisa kana vakave marara munzvimbo," Thompson akadaro, achikurudzira mapurasitiki anoodegradable aya anogona kunge ari kukonzera matambudziko akawanda kupfuura aanogadzirisa.
Zvakaitwa neVatsvakurudzi
Vatsvakurudzi vakaunganidza mienzaniso yemarudzi mashanu emabhegi epurasitiki.
Rudzi rwekutanga rwakanga rwakagadzirwa nepamusoro-density polyethylene - purasitiki yakajairika inowanikwa mumabhegi ezvitoro.Yakashandiswa sekuenzanisa kune mamwe mabhegi mana akanyorwa se eco-hushamwari:
Bhokisi repurasitiki rinoodza rakagadzirwa nechidimbu kubva kumagomba emaoyster
Mhando mbiri dzemabhegi akagadzirwa kubva kuoxo-biodegradable plastic, ane zvinowedzerwa zvinonzi nemakambani zvinobatsira mapurasitiki kuparara nekukurumidza.
Bhegi rinoita compostable rakagadzirwa kubva kumiti yemiti
Imwe neimwe mhando yebhegi yakaiswa munzvimbo ina.Mabhegi ese nemabhegi akachekwa kuita mitsetse akavigwa muivhu rebindu kunze, akanyudzwa mumvura ine munyu mune marina, akasiiwa achioneswa masikati uye nemhepo yakavhurika, kana kuvharirwa mumudziyo wakasviba mulabhu inodzorwa tembiricha.
Okisijeni, tembiricha uye chiedza zvese zvinoshandura chimiro chepurasitiki mapolymers, akadaro Julia Kalow, a polymer chemist kubva kuNorthwestern University, asina kubatanidzwa muchidzidzo ichi.Saizvozvowo zvinogona kuita nemvura uye kusangana nemabhakitiriya kana mamwe marudzi ehupenyu.
Zvakawanikwa Nemasayendisiti
Kunyangwe munzvimbo yakaoma yegungwa, uko algae nemhuka zvakakurumidza kuvhara purasitiki, makore matatu akange asina kureba zvakakwana kuputsa chero mapurasitiki kunze kwechirimwa-based compostable sarudzo, iyo yakanyangarika pasi pemvura mukati memwedzi mitatu.Mabhegi akatorwa nechirimwa, zvisinei, akaramba akasimba asi asina simba paakavigwa pasi pevhu rebindu kwemwedzi makumi maviri nemanomwe.
Kurapa chete kwairamba kuputsa mabhegi ese kwaive kuratidzwa kumhepo yakavhurika kwemwedzi inopfuura mipfumbamwe, uye muchiitiko ichocho kunyange bhegi rekare re polyethylene rakaparara kuita zvidimbu mwedzi gumi nemisere isati yapera.
