Lub khw muag khoom loj Morrisons tab tom nce tus nqi ntawm nws cov hnab yas rov qab los ntawm 10p txog 15p raws li kev sim thiab qhia txog 20p daim ntawv version.Cov hnab ntawv yuav muaj nyob rau hauv yim lub khw muag khoom raws li ib feem ntawm kev sim ob lub hlis.Lub khw muag khoom loj tau hais tias txo cov yas yog lawv cov neeg siv khoom muaj kev txhawj xeeb txog ib puag ncig.
Cov hnab ntawv tseem nrov hauv Asmeskas, tab sis lawv poob tawm ntawm kev siv hauv UK cov khw muag khoom hauv xyoo 1970s vim tias cov yas tau pom tias yog cov khoom siv ruaj khov dua.
Tab sis cov hnab ntawv puas yog ib puag ncig zoo dua li cov yas?
Cov lus teb los mus rau:
• Lub zog npaum li cas yog siv los ua lub hnab thaum lub sijhawm tsim khoom?
• Lub hnab ntev npaum li cas?(ie pes tsawg zaus nws tuaj yeem rov qab siv tau?)
• Nws yooj yim npaum li cas los siv dua?
• Nws puas sai sai yog tias muab pov tseg?
'Plaub lub zog ntau dua'
Hauv xyoo 2011ib daim ntawv tshawb fawb tsim los ntawm Northern Ireland Assemblyhais tias nws "yuav siv ntau tshaj plaub npaug ntawm lub zog los tsim lub hnab ntawv raws li nws ua los tsim lub hnab yas."
Tsis zoo li cov hnab yas (uas daim ntawv tshaj tawm hais tias yog tsim los ntawm cov khoom pov tseg ntawm cov roj refining) daim ntawv yuav tsum tau txiav cov hav zoov kom tsim cov hnab.Cov txheej txheem tsim khoom, raws li kev tshawb fawb, kuj tseem ua kom muaj cov tshuaj lom ntau dua piv nrog kev siv cov hnab yas ib zaug.
Cov hnab ntawv kuj hnyav dua li yas;qhov no txhais tau tias kev thauj mus los yuav tsum muaj zog ntau dua, ntxiv rau lawv cov pa roj carbon hneev taw, txoj kev tshawb fawb ntxiv.
Morrisons hais tias cov khoom siv los ua nws lub hnab ntawv yuav yog 100% los ntawm cov hav zoov uas tau tswj hwm lub luag haujlwm.
Thiab yog tias cov hav zoov tshiab tau cog qoob loo los hloov cov ntoo uas ploj lawm, qhov no yuav pab txhawb kev hloov pauv huab cua, vim cov ntoo kaw cov pa roj carbon monoxide los ntawm huab cua.
Xyoo 2006, Lub Chaw Haujlwm Ib puag ncig tau tshuaj xyuas ntau lub hnab ua los ntawm cov ntaub ntawv sib txawv kom paub seb lawv yuav tsum tau siv ntau npaum li cas thiaj li muaj peev xwm ua kom lub ntiaj teb qis dua li cov hnab yas siv ib zaug.

Txoj kev kawmpom cov hnab ntawv yuav tsum tau rov qab siv tsawg kawg peb zaug, ib qho tsawg dua cov hnab yas rau lub neej (plaub zaug).
Nyob rau lwm qhov kawg ntawm lub spectrum, Lub Chaw Haujlwm Saib Xyuas Ib Cheeb Tsam tau pom tias cov hnab paj rwb yuav tsum tau siv ntau tshaj plaws, ntawm 131. Qhov ntawd tau nqis mus rau lub zog loj uas siv los tsim thiab fertilize paj rwb xov paj.
• Morrisons mus sim 20p hnab ntawv
• Tshawb xyuas qhov tseeb: Tus nqi hnab yas mus qhov twg?
• Tshawb xyuas qhov tseeb: Lub roob khib nyiab yas nyob qhov twg?
Tab sis txawm hais tias ib lub hnab ntawv yuav tsum tau siv tsawg kawg yog qhov kev xav tau: nws puas yuav kav ntev txaus kom muaj sia nyob tsawg kawg peb mus rau lub tsev loj?
Cov hnab ntawv tsis zoo li lub hnab rau lub neej, feem ntau yuav sib cais lossis tsim kua muag, tshwj xeeb tshaj yog tias lawv ntub.
Hauv nws qhov xaus, Lub Chaw Haujlwm Ib puag ncig tau hais tias "nws tsis zoo li lub hnab ntawv tuaj yeem rov siv tau raws li qhov xav tau ntawm lub sijhawm vim nws tsis tshua muaj zog".
Morrisons hais tias tsis muaj laj thawj vim li cas nws lub hnab ntawv tsis tuaj yeem rov siv tau ntau zaus raws li lub hnab yas nws hloov, txawm hais tias nws nyob ntawm seb lub hnab kho li cas.
Cov hnab paj rwb, txawm tias yog cov pa roj carbon ntau tshaj rau kev tsim khoom, yog qhov ruaj khov tshaj plaws thiab yuav muaj lub neej ntev dua.
Txawm hais tias nws tsis tshua muaj zog, ib qho txiaj ntsig ntawm daim ntawv yog tias nws decomposes sai dua li cov yas, thiab yog li ntawd nws tsis tshua muaj peev xwm ua rau cov khib nyiab thiab ua rau muaj kev pheej hmoo rau cov tsiaj qus.
Daim ntawv kuj tseem siv tau dav dua, thaum lub hnab yas tuaj yeem siv sijhawm li ntawm 400 txog 1,000 xyoo los decompose.
Yog li dab tsi yog qhov zoo tshaj?
Cov hnab ntawv yuav tsum tau rov siv dua tsawg dua li lub hnab rau lub neej kom lawv muaj kev nyab xeeb ntau dua li cov hnab yas siv ib zaug.
Ntawm qhov tod tes, cov hnab ntawv tsis muaj zog dua li lwm hom hnab.Yog li yog tias cov neeg siv khoom yuav tsum hloov lawv cov ntawv ntau zaus, nws yuav muaj kev cuam tshuam ntau dua ib puag ncig.
Tab sis tus yuam sij los txo qhov cuam tshuam ntawm txhua lub hnab nqa khoom - txawm tias lawv tau ua los ntawm - yog kom rov siv tau ntau li ntau tau, hais tias Margaret Bates, tus xibfwb ntawm kev tswj xyuas cov khib nyiab ruaj khov ntawm Northampton University.
Ntau tus neeg tsis nco qab nqa lawv lub hnab rov qab siv tau ntawm lawv lub khw muag khoom txhua lub limtiam, thiab xaus rau yuav tsum tau yuav ntau lub hnab thaum mus txog, nws hais.
Qhov no yuav muaj kev cuam tshuam loj dua ib puag ncig piv nrog tsuas yog xaiv siv ntawv, yas lossis paj rwb.
