Yas tuaj yeem muaj sia nyob peb txhua tus
Xav tias kev txwv tag nrho cov yas no yog overkill?Muaj qee qhov laj thawj tseem ceeb vim li cas nws ua rau kev nkag siab.Ua ntej, yas hauv qhov chaw pov tseg tsuas yog tsis ploj mus.Raws li Weldon, lub hnab yas yuav siv sij hawm 10 mus rau 20 xyoo kom degrade, thaum lub raj mis yas siv yuav luag 500 xyoo.Thiab, txawm tias thaum nws "tawm mus," nws cov seem tseem nyob.
“Plastic yeej tsis tawg lossis ploj mus;Nws tsuas yog tawg mus rau hauv cov me me thiab me me kom txog rau thaum lawv muaj cov kab mob me me uas lawv tuaj yeem pom hauv peb cov huab cua thiab peb cov dej haus, " Kathryn Kellogg, tus sau thiab tus tsim ntawm lub vev xaib txo cov khib nyiab Going Zero Waste, hais hauv email.
Qee lub khw muag khoom noj tau hloov mus rau biodegradable hnab yas khw muag khoom raws li txoj hauv kev kom tau raws li cov neeg siv khoom hauv nruab nrab, tab sis kev tshawb fawb qhia tias qhov no tsis yog ib qho kev daws teeb meem.Ib txoj kev tshawb fawb los ntawm cov kws tshawb fawb ntawm University of Plymouth hauv tebchaws Askiv tau tshuaj xyuas 80 ib leeg-siv cov hnab ntim khoom noj khoom haus uas ua los ntawm cov yas biodegradable hauv peb lub xyoos.Lawv lub hom phiaj?Txiav txim siab li cas "biodegradable" cov hnab no tiag tiag.Lawv qhov kev tshawb pom tau luam tawm nyob rau hauv phau ntawv journal Environmental Science & Technology.

Lwm qhov laj thawj ntau lub tebchaws txwv tsis pub siv cov yas ib zaug yog vim lawv yuav tsum tsis txhob rov siv dua, txawm tias peb lub hom phiaj zoo tshaj plaws.Raws li ntau lub nroog forego recycling, nws yog kev ntxias kom coj teeb meem rau hauv koj tus kheej txhais tes los ntawm kev rov siv dua (thiab yog li "rov ua dua") lub raj mis yas thiab ntim.Tseeb, qhov no yuav ua haujlwm rau lub hnab, tab sis cov kws tshaj lij hais kom ceev faj thaum nws los txog rau lub raj mis yas lossis ntim khoom noj.Ib txoj kev tshawb fawb hauv Environmental Health Perspectives tau pom tias txhua yam khoom siv yas siv hauv cov thawv ntim khoom noj thiab lub raj mis yas tuaj yeem tso cov tshuaj phem yog siv ntau zaus.(Qhov no suav nrog cov uas hais tias tsis pub muaj bisphenol A [BPA] - cov tshuaj tsis sib haum xeeb uas tau txuas nrog kev cuam tshuam hormonal.)
Thaum cov kws tshawb fawb tseem tshuaj xyuas qhov kev nyab xeeb ntawm cov yas rov qab siv dua, cov kws tshaj lij pom zoo kom iav los yog hlau kom tsis txhob muaj cov tshuaj phem.Thiab raws li Weldon, nws yog lub sij hawm peb txais yuav ib tug reuse mindset - yog nws paj rwb tsim hnab, stainless hlau straws los yog ib tug tag nrho-ntawm xoom-khoom pov tseg.
Nws hais tias "Qhov phem tshaj plaws ntawm txhua yam khoom siv ib zaug yog tias peb txo qis ib yam dab tsi rau qhov peb xav muab pov tseg," nws hais."Cov kab lis kev cai yooj yim tau ua rau tus cwj pwm phem no ua rau muaj kev puas tsuaj thiab vim li ntawd, peb tsim ntau lab tons ntawm nws txhua xyoo.Yog tias peb hloov peb lub siab xav txog yam peb haus, peb yuav paub ntau ntxiv txog cov yas siv ib zaug uas peb siv thiab peb tuaj yeem zam nws li cas.
