Cov laj thawj tseem ceeb ntawm cov khoom pov tseg:
· Cov khw muag khoom pov tseg cov khoom siv tas sij hawm;
· Cov tsev noj mov tshem tawm txhua yam uas cov neeg siv khoom tsis tau noj;
· Cov tib neeg pov tseg cov khoom noj zoo kawg nkaus uas lawv tsis xav noj, nrog rau cov zaub mov tsis zoo, lossis cov khoom noj uas yuav siv rau yav tom ntej, tab sis lub txee lub neej yog nyob rau lub sijhawm tas sijhawm.
Feem ntau ntawm cov khoom pov tseg, txawm nyob rau hauv cov teb chaws siab heev ntawm lub ntiaj teb no - piv txwv li, nyob rau hauv lub tebchaws United States - yog tsis siv nyob rau hauv txhua txoj kev. Txhua yam tsuas yog xaus rau hauv lub nroog pov tseg - ib qho kev pom uas yuav luag tsis muaj neeg nyob hauv nroog tau ntsib - ib yam li lub tsev tua tsiaj. Hmoov tsis zoo, cov khoom lwj hauv qhov chaw pov tseg tsis yog "tsuas yog dag", tab sis decompose, tso cov pa phem thiab ua rau ib puag ncig. Nyob rau tib lub sijhawm, cov pa roj methane, uas tawm los ntawm cov khoom noj pov tseg, yog 20 npaug txaus ntshai rau ib puag ncig dua li CO2 (cov pa roj carbon dioxide).
Muaj xov xwm zoo: thoob ntiaj teb, cov neeg ua lag luam thiab cov neeg ua haujlwm ntsuab tau ua cov kauj ruam tseem ceeb los daws cov teeb meem ntawm cov zaub mov pov tseg. Cov "thawj cim" no qhia tias tsis yog txhua tus neeg mob siab rau thiab yav tom ntej uas tsis muaj pov tseg yog ua tau.
1. Nyob rau hauv Boston (USA) non-profit organization “” (“Food for every day”) qhib lub khw txawv txawv. Ntawm no, ntawm tus nqi txo - rau cov neeg xav tau - lawv muag cov khoom uas tau tas sij hawm, tab sis tseem siv tau. Feem ntau ntawm cov khoom yog zaub tshiab, txiv hmab txiv ntoo, tshuaj ntsuab, khoom noj siv mis. Yog li, nws muaj peev xwm daws tau ob qho teeb meem ib zaug: pab cov neeg xav tau kev pab thiab txo cov khoom noj khoom haus uas thauj cov khib nyiab hauv nroog. Xws li lub khw tsis zoo li kev nyuaj siab, tab sis (wow, ib pob ntawm blackberries rau 99 xees!)
2. Nyob Fab Kis teb Nyob rau theem tsoomfwv, cov khw muag khoom loj tau txwv tsis pub pov tseg cov khoom tsis muag. Tam sim no cov khw muag khoom yuav tsum tau pub zaub mov tsis tau them nyiaj rau cov koom haum tsis muaj txiaj ntsig uas pab cov neeg txom nyem, los yog pub zaub mov ua tsiaj txhu noj, los yog compost (rov qab rau hauv av kom tau txais txiaj ntsig). Nws yog qhov pom tseeb tias cov kauj ruam zoo li no (hloov radical!) yuav cuam tshuam rau lub xeev ntawm lub teb chaws ecology.
3. Cov tsev kawm ntawv paub tias yuav tsim cov khoom pov tseg ntau heev. Thiab nws tseem paub meej tias tsis muaj kev daws teeb meem yooj yim rau qhov teeb meem no. Tab sis ntawm no, piv txwv li, Didcot tsev kawm ntawv rau cov ntxhais hauv UK yuav luag daws qhov teeb meem. Kev tswj hwm muaj peev xwm txo tau lub tsev kawm ntawv cov zaub mov pov tseg los ntawm 75% los ntawm kev xam phaj cov tub ntxhais kawm txog kev nyiam zaub mov thiab hloov cov ntawv qhia zaub mov. Tus nqi ntawm tsev kawm ntawv noj su tau nce ntxiv vim tias cov zaub mov npaj tau raug hloov nrog cov khoom noj tshiab tshiab, thiab cov menyuam yaus tau muaj kev xaiv zoo dua rau cov txiv hmab txiv ntoo thiab zaub, thaum txhim kho cov khoom noj nqaij zoo - vim li ntawd, cov thoob khib nyiab yog yuav luag tas, thiab tag nrho cov me nyuam zoo siab.
4. Santa Cruz City Hall (California, USA) tau txhawb nqa Zero Food Waste in Schools program. Yog li ntawd, ob peb lub tsev kawm ntawv "kev ua qauv qhia" ua rau cov pej xeem xav tsis thoob, txav qhov teeb meem mus tom ntej! Ib lub tsev kawm ntawv txo cov khoom noj txhua hnub los ntawm 30 phaus rau ... xoom (Puas muaj leej twg ntseeg tias qhov no ua tau?!). Lub secret, raws li nws hloov tawm, yog:
- compost organic pov tseg - tso cai rau cov tub ntxhais kawm muag txhua yam khoom tsis xav tau los ntawm lawv cov khoom noj su - thiab txhawb kom siv cov thawv rov qab siv tau uas cov tub ntxhais kawm nqa los ntawm tsev.
5. Lub Nroog San Francisco (Tebchaws Asmeskas) - ib qho ntawm cov qib siab tshaj plaws hauv ntiaj teb hauv kev daws teeb meem ntawm cov khoom noj pov tseg. Rov qab rau xyoo 2002, cov tub ceev xwm hauv nroog tau txais txoj haujlwm Zero Waste (), teeb tsa lub hom phiaj ntawm kev tshem tawm cov chaw pov tseg hauv nroog los ntawm 2020. Nws yuav zoo li kev tshawb fawb tsis tseeb, tab sis lub hom phiaj nruab nrab ntawm kev txo cov khib nyiab hauv nroog los ntawm 75% los ntawm 2010 tau ua. Raws li lub sijhawm ua ntej: lub nroog tau txo cov pov tseg los ntawm qhov tsis txaus ntseeg 77%! Qhov no ua tau li cas? Cov tub ceev xwm pib nrog lub teeb siab rau tsev so thiab tsev noj mov. Lub nroog cov tuam txhab tsim kho tau raug nug los ntawm txoj cai kom pov tseg tsawg kawg 23 cov khoom siv pov tseg. Txij li xyoo 2002, txhua qhov chaw tsim kho tshiab hauv nroog (cov tsev hauv nroog thiab cov chaw) tau tsim los ntawm cov khoom siv rov ua dua tshiab, yav tas los siv cov khoom siv hauv tsev. Cov khw loj yuav tsum muab cov hnab ntim pov tseg (yas) nkaus xwb rau cov nyiaj. Cov kev cai nruj tau raug qhia kom cov pej xeem yuav tsum tau muab cov khib nyiab pov tseg thiab rov ua dua cov khoom pov tseg uas tsis yog khoom noj. Ntau lwm cov kauj ruam tau coj mus rau kev yeej. Tam sim no lub hom phiaj ntawm kev txo cov pov tseg los ntawm 100% los ntawm 2020 tsis zoo li tsis muaj tseeb: hnub no, xyoo 2015, lub nroog cov khib nyiab tau txo los ntawm 80%. Lawv muaj caij nyoog rau 5 xyoo ntxiv (los yog ua ntej) ua qhov tsis ntseeg!
6. Nyob New York - lub nroog loj tshaj plaws hauv Tebchaws Meskas - qhov teeb meem loj nrog cov khoom noj pov tseg. 20% ntawm cov neeg nyob hauv xav tau lossis tsis tuaj yeem tau txais yam khoom noj tsawg kawg. Nyob rau tib lub sijhawm, 13 ntawm cov ntim txhua xyoo (4 lab tons) ntawm ntau yam pov tseg uas lub nroog pov rau hauv qhov chaw pov tseg yog cov khoom noj muaj tseeb!
Lub koom haum tsis muaj txiaj ntsig CityHarvest tab tom ua lub luag haujlwm los kaw qhov sib txawv ntawm qhov tsis txaus ntseeg, thiab lawv tau ua tiav ib nrab! Txhua hnub, lub tuam txhab cov neeg ua haujlwm rov faib 61688 kg (!) ntawm cov khoom zoo, khoom noj khoom haus zoo los ntawm cov khw noj mov, khw muag khoom noj, cov khw noj mov, nrog rau cov neeg ua liaj ua teb thiab cov neeg tsim khoom noj, rau cov neeg pluag los ntawm txog 500 qhov kev pab cuam sib txawv los pab cov neeg pluag.

Tom qab tag nrho, koj tuaj yeem koom nrog hauv txoj haujlwm txo cov pov tseg tsis yog ntawm tsoomfwv qib, tab sis kuj nyob rau theem ntawm tus kheej! Tom qab tag nrho, tsuav koj khaws cov khoom pov tseg, koj puas tuaj yeem hu koj tus cwj pwm rau zaub mov 100% kev ncaj ncees? Yuav ua li cas?
