Ikozvino Mamiriro eChikafu Waste Conversion

Nhau dzichangoburwa dzekuraswa kwemarara echikafu

California's compost law (SB 1383) yakapasiswa kubva 2016 uye ichashandiswa muna 2022. Haisi kuzoshandiswa kusvika 2024 gore rino. Vermont neCalifornia dzakatopasa mutemo uyu. Kuti vashandure marara echikafu kuita mafuta, madhipatimendi ehurumende ari kushingaira kuvaka zvivakwa zvinodiwa, biogas digesters, uye michina yekugadzira manyowa, asi kufambira mberi kuchiri kunonoka.

Kune murimi wekuThompson, Conn., ane mbambo dzekupisira marara dziri pedyo dzichivhara uye mabhiri ekurasa marara achikwira, kushandura marara echikafu kuita simba kwaive kuhwina-kukunda. Kune rimwe divi, marara echikafu anotora chikamu che25% chemarara emuno kuti agadziriswe. Kune rumwe rutivi, methane inogadzirwa neanaerobic digester inoshandiswa pakupisa kwenzvimbo uye magetsi. Iyo yakagadziriswa digestate inogona kuiswa kune ivhu kuti iwedzere kubereka kwevhu. Zvakadaro, mutengo wekuvaka webiogas digesters wakakwira uye haugone kusangana zvizere nekugadzirwa kwemarara munharaunda. Pachine huwandu hwakawanda hwekudya kwekudya kunoda kugadziriswa.

Mashopu ekuAustralia anoshandisa tekinoroji yekuomesa yemuviri kuburitsa mvura mumarara echikafu kuderedza huremu uye huwandu hwemarara, kuchengetedza huwandu hukuru hwezvinovaka muviri uku uchichenesa pakupisa kwakanyanya. Zvinhu zvakagadziriswa zvinoshandiswa sechirauro uye zvinopihwa kumadziva ehove asingadyike. Ziva mashandisirwo ezviwanikwa uchirasa marara zvisina ngozi.

Sezvo pfungwa yekudzikisa kabhoni nekuchengetedzwa kwezvakatipoteredza yakatsanangurwa, vanhu vakawanda vakateerera kuraswa nekushandiswa kwemarara. Panguva ino, maererano nevashandisi vakasiyana, zvakasiyana-siyana zvinodiwa uye zvikero zvekugadzirisa, nzira yekusarudza teknolojia yakakodzera yekurapa tsvina yezvokudya kuti uderedze mari uye uwedzere kudzoreredza zviwanikwa uye mabhenefiti ehupfumi ave mubvunzo uri kufunga nezvevanhu. Heino chidimbu chipfupi chehunyanzvi hwazvino hwekuraswa kwemarara echikafu kupa vashandisi chirevo chekusarudza michina.

Inventory yefood waste resource conversion technologies

1.Landfill nzira

Nzira yechinyakare yekurasira marara inonyanya kubata marara asina kurongedzwa. Iyo ine zvakanakira zviri nyore uye yakaderera mutengo, asi iyo yakashata ndeyokuti inotora nzvimbo yakakura uye inotarisana nekusvibiswa kwechipiri. Parizvino, marara aripo anoviga marara akamanikidzwa kana madota mushure mekupiswa, uye anoita anti-infiltration kurapwa. Mushure mekunge marara echikafu azara, methane inogadzirwa neanaerobic fermentation inoburitswa mumhepo, ichiwedzera greenhouse effect. Kurasa marara hakukurudzirwe pakurasa tsvina yechikafu.

2.Biological treatment technology

Biological treatment tekinoroji inoshandisa tupukanana kuparadza organic mumarara echikafu uye kuchishandura kuita H2O, CO2 uye diki molecular organic matter kuderedza marara uye kugadzira shoma shoma yechinhu chakasimba chinogona kushandiswa sebiomass organic fetireza. Yakajairika biological kurapwa matekinoroji anosanganisira composting, aerobic fermentation, anaerobic fermentation, biogas digesters, nezvimwe.

Kuvirisa kweAnaerobic kunoshanda munzvimbo yakavharirwa zvizere pasi pemamiriro eanoxia kana kuti yakaderera okisijeni, uye inonyanya kugadzira methane, inogona kushandiswa sesimba rakachena uye kupiswa kugadzira magetsi. Zvakadaro, masara ebiogas anoburitswa mushure mekugayiwa ane huwandu hwakanyanya hweorganic uye achiri kuda kugadziridzwa uye kushandiswa se organic fetireza.

Mufananidzo. OWC Chikafu Waste Bio-Dgester midziyo kutaridzika uye yekuronga chikuva

Tekinoroji yekuvirisa yeAerobic inomutsa marara uye tupukanana zvakaenzana uye inochengetedza okisijeni yakakwana kuti ikurumidze kuora kwehutachiona. Iyo ine hunhu hwekushanda kwakagadzikana, mutengo wakaderera, uye inogona kuburitsa yakakwirira-mhando organic fertilizer substrate. HYHH's OWC Food Waste Bio-Digester inoshandisa yakakwirira-tembiricha aerobic fermentation tekinoroji uye nehungwaru kutonga kuti ive nechokwadi chekuti tembiricha iri mukati memidziyo yakagadzikana mukati meyepamusoro-basa rekuita re aerobic microorganisms. Kupisa kwepamusoro-soro kunogonawo kuuraya utachiona nemazai ezvipembenene mumarara.

3.Feed teknolojia

Iyo mall yekuAustralia yambotaurwa inoshandisa tekinoroji yakaoma yekudya-mu-feed. Dry feed tekinoroji ndeyekuomesa chikafu marara pa95 ~ 120 ℃ kweanopfuura maawa maviri kuderedza mwando wemarara kusvika pasi pe15%. Mukuwedzera, kune nzira yeprotein feed, iyo yakafanana nekurapa kwehupenyu uye inopinza ma microorganisms akakodzera mumarara kushandura organic matter kuita mapuroteni zvinhu. Chigadzirwa chacho chinogona kushandiswa sechirauro kana mombe nemakwai. Iyi nzira inonyanya kukodzera mamiriro ezvinhu apo tsime remarara ezvokudya rakagadzikana uye zvikamu zvaro zviri nyore.

4.Collaborative incineration nzira

Tsvina yezvokudya ine mvura yakawanda, kupisa kwakadzika, uye haisi nyore kupisa. Mimwe zvirimwa zvekupisa zvinosanganisa tsvina yechikafu isati yacheneswa mumarara ekanzuru muchikamu chakakodzera chekupisa pamwe chete.

5.Simple mhuri compost bucket

Nekudzika kwekuziva kwezvakatipoteredza uye kufarirwa kweInternet, kune zvakawanda zvakatumirwa kana mavhidhiyo pamusoro pekugadzira chikafu chepamba chinorasa compost mabhini. Tekinoroji yecompost yakarerutswa inoshandiswa kudzoreredza tsvina yechikafu inogadzirwa kumba, uye zvigadzirwa zvakaora zvinogona kushandiswa kuisa fetiraiza pachivanze. Nekudaro, nekuda kwekusarudzwa kweiyo microbial agents, chimiro chemumba compost bucket, uye zvikamu zvemarara echikafu pachayo, mhedzisiro inosiyana zvakanyanya, uye matambudziko akadai sekunhuhwirira kwakasimba, kuparara kusina kukwana, uye nguva yakareba yecompost inogona kuitika.
