Biodegradable Chovala Pulasitiki Chikwama

Chikwama cha compostable lifecycle ndi:
Kupanga: Wowuma wa chimanga amachotsedwa kuzinthu zopangira, polima wachilengedwe wotengedwa kuchokera ku wowuma wa chimanga, tirigu kapena mbatata.
Ndiye tizilombo toyambitsa matenda timasintha kukhala molekyu yaing'ono ya lactic acid yomwe imagwira ntchito ngati maziko opangira unyolo wa polima wa polylactic acid.
Unyolo wolumikizirana wa polymeric wa polylactic acid umapangitsa pepala la pulasitiki losawonongeka lomwe limagwira ntchito ngati maziko ofotokozera zinthu zambiri zapulasitiki zosaipitsa.
Pulasitiki iyi imatumizidwa kumakampani opanga komanso kusintha kwamatumba apulasitiki.
Kenako amagawidwa kumabizinesi kuti azigwiritsa ntchito komanso kugulitsa matumba a kompositi m'moyo wawo watsiku ndi tsiku.
Thumba limagwiritsidwa ntchito kenako limawonongeka (nthawi yoyerekeza yogwiritsidwa ntchito: mphindi khumi ndi ziwiri)
Njira ya biodegradation imakhala nthawi yoyerekeza kuyambira miyezi 6 mpaka 9.
The bioplastics yotengedwa ku chimanga wowuma wakhala gwero kosatha ndi zongowonjezwdwa, amapereka moyo waufupi ndi wotsekedwa monga ulimi waukulu, madzi otsika kudya, kulimbikitsa kukula kwa zokolola ndi kukulitsa kukula kwa mbewu m'munda. njira yotupa.Muzochitika zonse zamoyo, zowononga zimachepa mpaka 1000% poyerekeza ndi kupanga matumba apulasitiki.
Chomwe chimakhala ndi Compostable bag ndikuti chitha kugwiritsidwa ntchito ngati feteleza wazomera zakunyumba, ndikupangitsa kuti zikule bwino ndikulimbikitsa kugwiritsanso ntchito matumba apulasitiki.Ndi matumba a AMS Compostables, kuphatikiza kutulutsa zogwiritsidwanso ntchito, amapewa kusonkhanitsa zinyalala zosafunikira m'malo otayirako ukhondo komanso kuchepetsa kuchuluka kwa zinyalala ndi cholinga chokweza thanzi la anthu komanso chilengedwe.
Munthu wamba amagwiritsa ntchito thumba la pulasitiki kwanthawi yochepa ngati mphindi 12 asanalitaye, osaganizira komwe lingapite.
Komabe ikangotumizidwa kumalo otayirako, katundu wamba wamba wamba amatenga zaka mazana kapena masauzande kuti awonongeke - kuposa moyo wamunthu.Matumba amapanga kuchuluka kowopsa kwa pulasitiki yomwe imapezeka m'mimba mwa chinsomba kapena zisa za mbalame, ndipo sizodabwitsa - padziko lonse lapansi, timagwiritsa ntchito matumba apulasitiki 1 mpaka 5 thililiyoni chaka chilichonse.
Matumba apulasitiki osawonongeka amagulitsidwa ngati njira zokometsera zachilengedwe, zomwe zimatha kusweka kukhala zinthu zopanda vuto mwachangu kuposa mapulasitiki achikhalidwe.Kampani ina inati chikwama chawo chogulira zinthu “chidzanyonyotsoka ndi kuonongeka mosalekeza, chosasinthika, ndi chosaimitsidwa” ngati chidzakhala zinyalala m’chilengedwe.
Pakafukufuku yemwe adasindikizidwa sabata ino mu Environmental Science and Technology, ofufuza adayika matumba omwe amati ndi ochezeka ndi zachilengedwe opangidwa kuchokera kuzinthu zosiyanasiyana za organic ndi pulasitiki ndikuchokera kumasitolo aku UK kuti ayesedwe.Pambuyo pa zaka zitatu zokwiriridwa m'nthaka yamaluwa, yomizidwa m'madzi a m'nyanja, powonekera poyera ndi mpweya kapena kubisala mu labotale, palibe matumba omwe adasweka kwathunthu m'malo onse.
Zothandizidwa
M'malo mwake, matumba osawonongeka omwe adasiyidwa pansi pamadzi m'madzi adatha kusungabe zakudya zambiri.
"Kodi ntchito ya ena mwa ma polima otsogola komanso atsopanowa ndi chiyani?"anafunsa Richard Thompson, katswiri wa zamoyo zam'madzi wochokera ku yunivesite ya Plymouth komanso wolemba wamkulu wa phunziroli.Polima ndi mankhwala obwerezabwereza omwe amapanga pulasitiki, kaya ndi biodegradable kapena synthetic.
"Iwo ndi ovuta kukonzanso ndipo amachedwa kuwononga ngati atakhala zinyalala m'chilengedwe," adatero Thompson, kutanthauza kuti mapulasitiki owonongekawa angayambitse mavuto ambiri kuposa momwe amathetsera.
Zimene Ofufuza Anachita
Ofufuzawa adasonkhanitsa zitsanzo zamitundu isanu yamatumba apulasitiki.
Mtundu woyamba unali wopangidwa ndi polyethylene yochuluka kwambiri - pulasitiki yokhazikika yomwe imapezeka m'matumba a golosale.Anagwiritsidwa ntchito ngati kufananitsa matumba ena anayi olembedwa kuti ndi ochezeka:
Thumba lapulasitiki losawonongeka lopangidwa mwa zina kuchokera ku zipolopolo za oyster
Mitundu iwiri yamatumba opangidwa kuchokera ku pulasitiki ya oxo-biodegradable, yomwe ili ndi zowonjezera zomwe makampani amati zimathandiza pulasitiki kusweka mwachangu.
Chikwama chopangidwa ndi manyowa opangidwa kuchokera ku mbewu
Mtundu uliwonse wa thumba unayikidwa m'malo anayi.Matumba athunthu ndi matumba odulidwa mumizere amayikidwa m'nthaka yamunda panja, kumizidwa m'madzi amchere mumchenga, kusiyidwa masana ndi kunja, kapena kusindikizidwa mu chidebe chamdima mu labu yoyendetsedwa ndi kutentha.
Oxygen, kutentha ndi kuwala zonse zimasintha mapangidwe a ma polima apulasitiki, adatero Julia Kalow, katswiri wa sayansi ya polima wochokera ku yunivesite ya Northwestern University, yemwe sanachite nawo phunziroli.N'chimodzimodzinso ndi mmene madzi amachitira ndi mabakiteriya kapena zamoyo zina.
Zimene Asayansi Anapeza
Ngakhale m'madera ovuta a m'nyanja, kumene ndere ndi zinyama zinaphimba pulasitiki mwamsanga, zaka zitatu sizinali nthawi yokwanira kuthyola pulasitiki iliyonse kupatulapo njira yopangira manyowa, yomwe inasowa m'madzi mkati mwa miyezi itatu.Matumba opangidwa ndi zomera, komabe, adakhalabe koma adafowoka atakwiriridwa pansi pa dothi lamunda kwa miyezi 27.
Chithandizo chokhacho chomwe chinkathyola matumba onse chinali kutsegula mpweya kwa miyezi yoposa isanu ndi inayi, ndipo zikanakhala choncho, ngakhale thumba lachikale la polyethylene linagawanika kukhala zidutswa miyezi 18 isanadutse.
