Wisconsin Saib yog chav xov xwm tsis muaj txiaj ntsig uas tsom mus rau tsoomfwv kev ncaj ncees thiab teeb meem ntawm lub neej zoo. Sau npe rau peb tsab ntawv xov xwm rau ntau zaj dab neeg ncaj nraim rau koj inbox thiab pub los txhawb peb qhov tseeb-kuaj sau xov xwm. Zaj dab neeg no yog ib feem ntawm lub series Tshaj dhau Hunger.

Txog rau tam sim no, Lub Tsev Kawm Ntawv Qib Siab Wisconsin-Madison muaj txoj haujlwm ua tiav rau cov khoom noj uas tau muab pov tseg. 

Pib xyoo 2009, lub tsev kawm ntawv tau sau cov khoom noj khoom haus ntawm cov tsev noj mov hauv tsev kawm ntawv kom xa mus rau West Madison Agricultural Research Station rau kev ua chiv. Hauv xyoo 2018, lub tsev kawm ntawv tau pib nqa cov khoom seem rau lub tshuab hluav taws xob anaerobic, tam sim no muaj los ntawm Clean Fuel Partners LLC. Nyob ntawd, cov khib nyiab tau hloov mus ua methane rau roj.

Tab sis lub tuam txhab hloov nws lub hom phiaj, ua nws tso nws txoj kev koom tes nrog UW-Madison nyob rau xyoo 2021. Travis Blomberg, tus kws saib xyuas kev pabcuam hauv tsev kawm ntawv rau UW-Madison Lub Chaw Haujlwm Saib Xyuas Kev Ncaj Ncees, tau hais tias lub tshuab nqus tsev tsis noj zaub mov thiab tam sim no tsuas yog siv quav nyab los ua cov khoom siv. Qhov kev hloov ntawd kuj tau ua rau lub nroog Madison qhov kev sim ntawm cov khoom noj thoob plaws hauv nroog.

Ib lub nroog Madison lub tsheb thauj khoom tau tso peb lub hnab ntim khib nyiab tawm sab nraum Harmony Bar & Grill ntawm lub nroog East Side hauv 2017 thaum lub sijhawm tsav tsheb thauj khoom seem. Lub nroog tau xaus cov khoom siv rov ua dua tshiab hauv xyoo 2021 tom qab lub tshuab nqus tsev uas tau txais cov khoom seem hloov mus lees txais tsuas yog cov chiv los tsim cov roj methane.

Lub Xeev Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv kwv yees kwv yees li 1.2 lab tons ntawm cov ntaub ntawv hauv ib xyoos tuaj yeem hloov pauv ntawm qhov chaw pov tseg mus rau hauv cov chiv. Txog peb-plaub ntawm qhov ntawd yog cov khoom noj pov tseg, cov DNR hais tias, tsim methane, muaj teeb meem tsev cog khoom roj.   

Lub nroog thiab tsev kawm ntawv tsis yog ib leeg nyob rau hauv lawv txoj kev tawm tsam los tswj cov khoom noj khib nyiab loj loj. 

Tsuas yog 7% ntawm 1,000 lub nroog loj tshaj plaws hauv lub tebchaws muaj lub nroog curbside compost program uas lees txais cov khoom pov tseg - sawv cev tsuas yog 3% ntawm cov neeg Asmeskas, raws li ib puag ncig nonprofit GreenBlue. 

Los ntawm kev sib piv, 71% ntawm cov pej xeem hauv Canada muaj nkag mus rau qhov kev pab cuam curbside uas ua cov organics sib cais, suav nrog cov khoom noj khoom haus, raws li Ontario-based Environmental Research thiab Education Foundation.

Ib tug kws paub txog kev tswj cov khib nyiab tau piav qhia tias nws yog "Catch-22" rau Wisconsin.  

"Peb xav tau cov neeg los hloov cov khoom siv los tsim kev lag luam txaus rau cov chaw uas xav tau cov chiv thiab tom qab ntawd muaj kev lag luam txaus rau cov. Thiab lawv txhua tus yuav tsum tshwm sim ib txhij, "said Casey Lamensky, DNR tus neeg saib xyuas cov khib nyiab khib nyiab. "Thiab peb tseem ntxov txaus tias yog ib qho ntawm cov kev xaiv ntawd poob los, tsis muaj ntau cov kev daws teeb meem rov qab."

Txiav tawm los ntawm kev sib kis

Ua ntej thaum kawg nws raug yuam kom kaw, UW-Madison qhov kev pab cuam composting tau dhau los ntawm kev poob qis nrog rau kev sib kis ntawm nws cov kwj deg. 

Ntawm West Madison Agricultural Research Chaw Nres Tsheb, lub tsev kho mob churns thiab aerates organic pov tseg nyob rau hauv ntev kab los tsim compost. Tab sis nws nyuaj rau kev ua cov ntaub ntawv tsis-compostable - xws li hnab yas, ntim thiab hlau - hauv cov khoom noj khoom haus los ntawm tsev kawm ntawv, Blomberg tau hais. 

Compost bins thiab cov lus qhia muaj rau cov neeg ua noj hauv chav ua noj ntawm Gordon Dining thiab Event Center ntawm University of Wisconsin-Madison. Lub tsev kawm ntawv yav dhau los tau ua haujlwm loj-loj composting program, tab sis qhov ntawd tau scuttled tom qab biodigester uas hloov cov khoom seem rau hauv methane hloov mus rau tsuas yog txais cov quav quav nyuj xwb. (Ruthie Hauge / Cap Times)

Lub tsev kawm ntawv tau sim ua “huv lub kwj” ntawm nws cov khoom pov tseg, nrhiav cov tub ntxhais kawm los ua cov kev tshawb xyuas thoob khib nyiab hauv tsev kawm ntawv cov tsev noj mov thiab kev cob qhia cov neeg ua haujlwm los txheeb xyuas cov khoom pov tseg thiab khiav nws los ntawm lub tshuab pulper. 

Txawm li cas los xij, cov pov tseg los ntawm cov teeb meem tshwm sim hauv tsev kawm ntawv - cov ntawv ntim thiab cov ntaub so ntswg ua rau lub cev qeeb, thiab cov khoom sib sib zog nqus tau ploj mus. Lub chaw ua liaj ua teb kuj yuav tsum tau kho cov tsheb laij teb tsheb laij teb uas tau chob los ntawm cov hlau nyiaj pov tseg rau hauv cov khib nyiab khib nyiab. 

Cov kab mob sib kis tau nyob hauv "pem hauv ntej ntawm lub tsev" cov ntaub ntawv, cov khoom noj khoom haus pov tseg los ntawm cov neeg siv khoom noj khoom haus, Blomberg tau hais. Kev kis kab mob ntawm cov khoom tsis yog compostable yog "ib txwm muaj teeb meem" nrog kev sau cov khoom noj pov tseg, nws hais ntxiv, "qhov kev zov me nyuam tsis zoo tag nrho." 

Yog li thaum muaj lub sijhawm tshwm sim hauv 2018 los hloov lub tsev kawm ntawv cov kev pab cuam compost mus rau qhov chaw digester anaerobic - uas cais cov zaub mov los ntawm cov khoom paug nrog lub tshuab depacker - Blomberg tau hais tias lub tsev kawm ntawv tau kos npe mus txog rau thaum cov neeg ua haujlwm digester tau tso tseg cov khoom noj khoom haus thaum Lub Xya Hli 2021. 

Blomberg tau hais tias "Peb tuaj yeem ua txhua yam hauv peb lub zog, tab sis peb tsis muaj cov khoom sib xyaw ua ke nyob ze peb uas (xav tau) cov khoom," Blomberg tau hais. 

Municipal composting falters 

Zoo li UW-Madison, lub nroog Madison tau coj ntau qhov kev pib ua zaub mov - tag nrho cov no tau ua pov thawj tias tsis muaj hmoo. 

Txoj haujlwm tsis ntev los no uas tau muab pov tseg los ntawm lub nroog tau tso cai rau cov neeg nyob hauv lawv cov khoom pov tseg ntawm peb qhov chaw sib txawv. Tom qab ntawd cov khoom raug xa mus rau lub biodigester uas rho tawm methane los ntawm cov pov tseg. Qhov kev pab cuam tuaj txog kawg tom qab lub biodigester pib rho methane tsuas yog los ntawm nyuj quav - tib qhov kev hloov pauv uas tau xaus UW-Madison txoj haujlwm, raws li lub nroog tus neeg ua haujlwm rov ua dua tshiab Bryan Johnson.  

Lub nroog yav dhau los tau sim ob qhov kev pab cuam composting, tab sis kev siv zog ua tsis tau vim nws siv zog heev - thiab cov khoom noj khoom haus feem ntau muaj paug. Lub tsho hangers, phuam da dej, cov khoom ua si menyuam yaus - thiab txawm tias ib lub taub hau mos lwj - yog cov khoom uas ua rau muaj kev sib kis, Johnson tau hais. 

Cov khoom noj khoom haus tau muab khaws cia ntawm South Madison Farmers' Market thaum Lub Rau Hli 14, 2022 hauv Madison, Wis. Qhov kev pab cuam txais cov txiv hmab txiv ntoo nyoos, zaub, kas fes, nplej, nplej, xoob tshuaj yej, qe thiab gourds.

Tab sis Madison tab tom muab cov khoom seem rov ua dua lwm qhov. Ua tsaug rau qhov nyiaj pab los ntawm US Department of Agriculture, lub nroog qhib ob qho khoom noj khib nyiab tso tawm ntawm cov neeg ua liaj ua teb cov khw muag khoom lub caij ntuj sov no, uas mus rau Neighborhood Food Solutions ua liaj ua teb hauv Fitchburg rau composting. Cov chaw ntawm South Madison thiab East Side cov khw muag khoom yuav Ua haujlwm mus txog Lub Kaum Hli 25. 

Thaum lub sijhawm ua haujlwm yog "me me," Johnson tau hais tias nws vam tias yuav nthuav dav cov chaw. Txog tam sim no, ob qhov chaw pib tau sau ze li 8,000 phaus ntawm cov khoom seem. Nws tsis yog ntau tab sis, nws hais tias, txhua tuj ntawm compost yog "yeej." 

Nyob rau lub sijhawm ntev, lub nroog vam tias yuav ua haujlwm nrog Dane County's Sustainability Campus – a muab pov tseg thiab cov phiaj xwm pov tseg pov tseg tau npaj rau Yahara Hills Golf Course - los tsev rau qhov kev pab cuam loj. 

Johnson tau hais tias "Los ntawm txhua qhov kev puas tsuaj uas peb tau muaj nyob hauv txoj kev, nws nyuaj rau kev cia siab, tab sis kuv tseem muaj kev cia siab rau qhov no," Johnson tau hais. "Kuv paub tias peb yuav ua nws - nws tau siv sijhawm ntev dua li kuv xav tias leej twg xav tau nws."

Minnesota ua ntej ntawm kev cog qoob loo

Minnesota muaj ntau yam kev pab cuam hauv nroog - suav nrog ntau yam uas sau cov khoom siv organic curbside. Ramsey/Washington County Recycling & Energy Center hauv Minnesota npaj yuav tso tawm curbside food scrap collection thaum kawg ntawm 2023. Nws yog coj los ntawm UW-Madison kawm tiav Junalee Ly. 

Cov neeg nyob hauv yuav sau lawv cov zaub mov pov tseg rau hauv cov hnab ntim khoom hnyav uas tau muab los ntawm ob lub nroog, muab pov tseg tib yam li lawv cov khib nyiab ib txwm lossis cov khoom siv rov ua dua tshiab kom rov qab tau ntawm qhov chaw ua cov khib nyiab rau kev sib xyaw, Ly hais. 

Nws tau hais tias "Peb qhov kev pabcuam tshwj xeeb vim nws tso siab rau cov khoom siv uas twb muaj lawm, thiab cov neeg siv thoob khib nyiab tsis tas yuav hloov ib yam dab tsi txog kev xa lawv cov kev pabcuam," nws hais.

Qhov tsis muaj kev tsim kho vaj tse hauv Wisconsin tau ua rau cov kev pab cuam hauv nroog xws li Madison qhov kev siv zog pib, tsuas yog mus rau tom khw. (Coburn Dukehart / Wisconsin Saib)

Lamensky, tus kws saib xyuas cov khoom pov tseg ntawm DNR, tau hais tias cov kev pab cuam khaws cov khoom khib nyiab muaj ntau dua hauv cov nroog loj dua, muaj neeg coob coob, tshwj xeeb tshaj yog nyob rau ntug hiav txwv. Hauv cov cheeb tsam no, uas muaj thaj tsam thaj tsam tsawg, tus nqi ntawm qhov chaw pov tseg tuaj yeem kim dua li kev ua chiv. 

Ib qho chaw ci ntsa iab hauv Wisconsin: Yard khib nyiab composting. Ib qhov chaw pov tseg txwv tsis pub vaj pov tseg tau siv nyob rau hauv lub xeev xyoo 1990 tau ua rau ntau tshaj 200 qhov kev pabcuam hauv nroog composting, xa kwv yees li 200,000 tons hauv ib xyoos ntawm nplooj, nyom clippings thiab me me txhuam rau hauv compost, uas feem ntau muab pub dawb. Ironically, uas ua rau cov khoom noj khib nyiab composting ib tug tougher lag luam endeavor nyob rau hauv lub xeev.

"(Cov khoom noj khib nyiab) feem ntau yog cov khoom lag luam tau txais txiaj ntsig ntau dua, tab sis nws yog ib qho nyuaj rau kev yuav khoom (khoom noj khoom haus) compost - txawm tias nws yog ib qho zoo dua compost - hauv lub xeev thaum muaj ib pawg ntawm cov khib nyiab khib nyiab muaj rau. dawb, ”nws hais.

Qhov tsis muaj vaj tse nyob hauv Wisconsin kuj ua rau cov kev pab cuam hauv nroog xws li Madison txoj kev siv zog los pib tsuas yog tom qab lub khw muag khoom xwb. Lamensky tau hais tias qhov kev rov ua dua, rov ua dua tshiab rau cov khoom noj compost tuaj yeem ua rau cov neeg nyob hauv tsis meej pem, ua rau muaj feem cuam tshuam rau cov dej khib nyiab rov qab, Lamensky tau hais. Nws cov lus qhia: Yog tias tsis ntseeg, muab pov tseg.

Cov kev pabcuam subscription dominate

Txawm hais tias Madison tau ua tsis tiav los txhawb nqa txoj haujlwm hauv nroog thoob plaws ntiaj teb, muaj cov tuam txhab ntiag tug uas hloov cov khoom seem rau hauv av - rau tus nqi.

Tsawg kawg yog peb qhov kev pabcuam - Curbside Composter, Ntiaj Teb Stew thiab Green Box Compost — muaj nyob rau hauv Madison cheeb tsam. Ben Stanger, tus tsim thiab CEO ntawm Green Box, tau pib nws lub tuam txhab ua ntej lub xyoo no los ua kom tiav qhov nws pom tias qhov kev xav tau loj hlob hauv cheeb tsam. Green Box them cov tswv cuab $24 ib hlis.

"Muaj ntau tus tub ntxhais hluas uas kuv xav tias muaj kev ruaj ntseg (raws li lub hom phiaj) feem ntau, tab sis kuj muaj cov khoom noj thiab cov khoom noj pov tseg tshwj xeeb tshaj yog ib yam dab tsi uas lawv xav tsom mus rau," Stanger tau hais. "Thiab kuv xav muab qhov no rau lawv hauv txoj hauv kev uas yooj yim thiab yooj yim thiab pheej yig."

Kwv yees li 100 tus neeg nyob hauv thiab ob lub tsev noj mov tau sau npe rau Green Box Compost kev pabcuam uas khaws lawv cov khoom pov tseg. Cov neeg siv khoom tuaj yeem sau cov khoom pov tseg xws li khob cij, nqaij, thiab mis nyuj. (Coburn Dukehart / Wisconsin Saib)

Lamensky hais tias subscription-based kev pabcuam zoo li Green Box txuas ntxiv tshaj cov kev pabcuam hauv nroog hauv lub xeev vim tias cov tuam txhab ntiag tug tuaj yeem "txav ntau dua," hla kev bureaucracy uas tuaj yeem ua haujlwm qeeb.

DNR sim pab los ntawm kev muab kev txhawb nqa rau Wisconsin hauv nroog thiab zam kev tshuaj xyuas thiab cov nqi ntawv tso cai tus qauv los txhawb cov kev pib ua haujlwm, nws hais. 

Qee lub xeev thiab hauv nroog muaj txoj cai lij choj hauv xeev uas txhawb kom hloov cov khoom seem ntawm qhov chaw pov tseg. Minnesota muaj ib tug txoj cai lub hom phiaj ntawm kev rov ua dua 75% ntawm nws cov pov tseg los ntawm 2030. Wisconsin tsis muaj qhov ntsuas qhov xav tau, tab sis DNR muaj lub hom phiaj los txo zaub mov pov tseg los ntawm 50% los ntawm 2030.

Txawm tias muaj kev sib tw, Lamensky cia siab tias ntau lub nroog yuav muab nws sim.

"Thiab thaum peb muaj ntau yam piv txwv ntawm no hauv Wisconsin, kuv vam tias lwm lub nroog yuav pom tias nws tau ua tiav zoo thiab tseem npaj ua raws li cov thawj coj ntawd," nws hais.

Tackling pov tseg ntawm nws qhov chaw

UW-Madison tab tom tshuaj xyuas cov kev xaiv sib txawv los nqa cov chiv ua kom rov qab mus rau hauv tsev kawm ntawv los ntawm kev sim ua haujlwm nrog Lub Chaw Tshawb Fawb Txog Kev Ua Liaj Ua Teb. Tsis zoo li qhov kev npaj yav dhau los, Blomberg tau hais tias cov khoom raug txwv rau "rov qab hauv tsev" cov khoom noj khoom haus los ntawm tsev kawm ntawv qib siab. plaub lub tshuab hluav taws xob khoom noj loj tshaj plaws - ua kom ntau tshaj li ib nrab ntawm tag nrho cov khoom pov tseg hauv tsev kawm ntawv. 

Tab sis txoj haujlwm tsav tsheb tsuas yog ib qho kev daws teeb meem ib ntus xwb, thiab lub tsev kawm ntawv cov lus pom zoo rau cov neeg muag khoom kom nrhiav tau qhov chaw ua kom cov chiv ua tau ntev tau ua tsis tiav, Blomberg tau hais. 

Madison muab cov lus qhia no los pab cov neeg nyob hauv kev txiav txim siab seb lawv tuaj yeem nqa mus rau qhov chaw muag khoom noj khoom haus. (Courtesy ntawm lub nroog Madison)

Lub tsev kawm ntawv tseem tab tom nrhiav lwm txoj hauv kev los txiav cov zaub mov pov tseg. Piv txwv li, ib pab neeg ntawm cov tub ntxhais kawm ruaj ntseg nyiaj rau cov khoom noj khib nyiab txo cov tshuab los ntawm cov Green Fund - ib qho kev pib uas pab cov tub ntxhais kawm cov phiaj xwm los daws cov teeb meem ib puag ncig ntawm UW-Madison lub tsev kawm ntawv.

Qhov project tso cov tshuab luam ntawv digital hauv cov thoob khib nyiab los tshuaj xyuas cov khoom noj twg raug pov tseg kom lub tsev kawm ntawv tuaj yeem kho nws cov khoom noj. 

"Nws yog ib qho yooj yim, yooj yim, siv tau cov kev daws teeb meem uas yuav tsis tsuas yog txuag lub tsev kawm ntawv nyiaj ntau, tab sis nws yuav txuag tau qee qhov teeb meem ntawm cov khib nyiab uas tau tsim thiab muab tso rau hauv qhov chaw pov tseg," said Jacob Breit, tus laus ua haujlwm ntawm lub qhov project.

Blomberg pom zoo tias kev txo cov khib nyiab tsawg kawg yog qhov kev daws teeb meem zoo tshaj plaws thiab yooj yim tshaj plaws.

Nws hais tias, "Cov lus nug loj dua," yog vim li cas peb thiaj li tsim cov khoom noj pov tseg ntau heev hauv thawj qhov chaw? Thiab qhov ntawd yog lo lus nug siv tau. "

Wisconsin Watch qhia txog kev ua haujlwm hauv Erin Gretzinger tau pab txhawb rau tsab ntawv ceeb toom no.
