Isikhwama sepulasitiki se-biodegrazekable Garment

Isikhwama se-Sig Lifecycle sithi:
Ukukhiqiza: Isitashi sommbila sikhishwa ezintweni ezingavuthiwe, i-polymer yemvelo etholwe esitashilweni sommbila, ukolweni noma amazambane.
Lapho-ke ama-microorganisms aguqula abe yi-molecule encane ye-lactic acid esebenza njengesisekelo sokukhiqizwa kwamaketanga we-polymer we-polylactic acid.
Amaketanga e-polymeric we-polymeric we-polylactic acid enikeza indawo ephepheni lepulasitiki le-biodegradable elisebenza njengesisekelo sokucaciswa kwemikhiqizo yepulasitiki engekho emthethweni.
Leli phepha lepulasitiki lithunyelwa ezinkampanini zokukhiqiza kanye noshintsho lwezikhwama zepulasitiki.
Ngemuva kwalokho basatshalaliswa kwizikhungo zezentengiso zokusetshenziswa kanye nokuthengiswa kwezikhwama ezikhohlisayo empilweni yabo yansuku zonke.
Isikhwama siyasetshenziswa bese kuba imfucuza (isikhathi esilinganisiwe sokusebenzisa: imizuzu eyishumi nambili)
Inqubo ye-biodegradation iba yisikhathi esilinganiselwa ezinyangeni ezi-6 kuye kwezingu-9.
Ama-bioplastics akhishwe esitobhini se-corn isiphenduke umthombo ongapheli futhi ovuselelekayo, aveze impilo efushane futhi evaliwe yokuphila okunjalo kokulima okukhulu, kudla amanzi aphansi, kuphoqeka ukukhula komkhakha wezitshalo futhi kuye kwenza ukuthi kube lula ukunwetshwa kwezitshalo ku indlela yokunikela. Kuyo yonke inqubo yomjikelezo wempilo, ama-ejenti okungcosa ancipha kuze kube yi-1000% uma uqhathanisa nenqubo yokukhiqizwa kwesikhwama sepulasitiki.
Ukupha kwesikhwama esikhohlisayo ukuthi bangasetshenziswa njengomanyolo izitshalo zasekhaya, futhi ngayonza bakhule baphilile futhi bagqugquzele ukufunwa kabusha kwezikhwama zepulasitiki. Ngama-AMS Comporations izikhwama, ngaphandle kokwenza ukulahlwa kabusha okusebenzayo, kuyavikeleka ukuqongelela imfucuza engenasidingo yokuhlanzeka komhlaba kanye nokunciphisa ukugcwala udoti ngenhloso yokuthuthukisa izimo zezempilo zomphakathi zomphakathi kanye nemvelo.
Umuntu ojwayelekile usebenzisa isikhwama sepulasitiki esijwayelekile isikhathi esifushane njengemizuzu eyi-12 ngaphambi kokuyiphonsa, ungalokothi ucabange ukuthi kungagcina kuphi.
Noma ngabe yathunyelwa ekugcwalisweni komhlaba, ukuthi i-Standard Grocery Store Tote ithatha amakhulu noma izinkulungwane zeminyaka ukudiliza - okungaphezulu kokuphila komuntu. Izikhwama zakha inani elishaqisayo lepulasitiki elitholwe eziswini zomkhomo noma izidleke zezinyoni, futhi akumangalisi - emhlabeni jikelele, sisebenzisa izikhwama zepulasitiki eziyizigidi eziyizinhlanu ngonyaka.
Izikhwama zepulasitiki ze-biodegramable zithengiswa njengezixazululo eziningi ze-eco-friendly, ezikwazi ukwehla zibe sezinto ezingenangozi ngokushesha kunamapulasithi endabuko. Inkampani eyodwa ifuna isikhwama sabo sokuthenga "izolimaza futhi i-biodegrade inqubo eqhubekayo, engenakuphikwa futhi engavinjekayo" uma igcina njenge-litter emvelweni.
Ocwaningweni olushicilelwe kuleli sonto kwisayensi yesayensi yezemvelo kanye nobuchwepheshe, abacwaningi bafaka izikhwama ezinobungane ze-eco-ezinobungane ezenziwe ngezinto ezahlukahlukene ze-organic nasepulasitiki futhi zitholwe ezitolo zase-UK zivivinye. Ngemuva kweminyaka emithathu kwangcwatshwa enhlabathini yengadi, efakwe emanzini olwandle, kuvezwe ukukhanya okuvulekile nomoya noma kuhlaselwe elabhorethri, azikho izikhwama ezigqekeziwe ngokuphelele kuzo zonke izindawo.
-Sixhaweyo
Eqinisweni, izikhwama ze-biodegradable ezazishiywe ngaphansi kwamanzi eMarina zisakwazi ukubamba umthwalo ophelele wokudla.
"Iyini indima yalezinye zalezi ama-polymers amasha futhi anoveli?" Ucele uRichard Thompson, isazi sezinto eziphilayo zasolwandle ezivela e-University of Plymouth kanye noMlobi omkhulu wokufunda. I-polymer iyiqoqo eliphindaphindwayo lamakhemikhali alwela isakhiwo sepulasitiki, kungaba yinto ye-biodegradable noma anthetic.
"Bayinselele ukuphinda baphinde basebenzise kabusha futhi bayephuza kakhulu ukungcola uma beba udoti emvelweni," kusho uThompson, ephakamisa lezi ziplasitiki ezingathandeki kunalokho abazixazulula.
Lokho okwenziwe ngabacwaningi
Abaphenyi baqoqa amasampula ezinhlobo ezinhlanu zezikhwama zepulasitiki.
Uhlobo lokuqala lwenziwe nge-polyethylene ephezulu kakhulu - ipulasitiki ejwayelekile etholakala ezikhwameni zezitolo zokudla. Kwakusetshenziswa njengokuqhathanisa ezinye izikhwama ezine ezibhalwe njenge-eco-friendly:
Isikhwama sepulasitiki se-biodegramable esenziwe ngokwengxenye kusuka kuma-Oyster Shells
Izinhlobo ezimbili zezikhwama ezenziwe nge-OXO-Biodegradable Plastic, equkethe izithasiselo izinkampani ezithi zisiza zisiza ipulasitiki ehlehla ngokushesha
Isikhwama esikhohlisayo esenziwe ngemikhiqizo yezitshalo
Uhlobo lwesikhwama ngasinye sabekwa ezindaweni ezine. Izikhwama ezigcwele kanye nezikhwama ezigayiwe zingcwatshwe enhlabathini engadini ngaphandle, zangena emanzini anosawoti e-marina, kwesokunxele kuvezwe ukukhanya kwemini nomoya, noma kuvalwe esitsheni esimnyama.
I-oksijini, izinga lokushisa nokukhanya konke kushintsha ukwakheka kwama-polymers epulasitiki, kusho uJulia Kalow, i-polymer chemist evela enyakatho nentshonalanga yeNyuvesi yaseNyakatho-ntshonalanga, eyayingenela kulolu cwaningo. Ngakho-ke futhi kungaphendula ngamanzi nokusebenzisana ngamagciwane noma ezinye izindlela zokuphila.
Okutholakele ososayensi
Ngisho nasendaweni enzima yasolwandle, lapho ama-algae nezilwane amboze khona ngokushesha ipulasitiki, iminyaka emithathu akulungile ngokwanele ukuba ahlukanise noma yimaphi amapulasitiki ngaphandle kwenketho esekelwe kwizitshalo, eyanyamalala ngaphansi kwezinyanga ezintathu. Izikhwama ezithathwe izitshalo, nokho, zaqhubeka ziqinile kodwa zibuthakathaka lapho zingcwatshwe ngaphansi kwenhlabathi engadini izinyanga ezingama-27.
Ukuphela kwendlela yokwelashwa okwahlukana njalo ngezikhwama zonke kwakuwukuvezwa komoya ovulekile izinyanga ezingaphezu kwesishiyagalolunye, futhi kuleso sikhwama ngisho nezinga, isikhwama sendabuko sendabuko sihlakazekile sibe yizicucu ngaphambi kwezinyanga eziyi-18 sesidlulile.
