M'zipinda zodyeramo zanyumba zamakono zamaofesi, kusintha mwakachetechete kozikidwa pa sayansi ya zinthu kukuchitika. Zotengera, matumba, ndi zokutira zomwe akatswiri amagwiritsa ntchito zikuchulukirachulukira kuchoka ku mapulasitiki wamba kupita ku kusankha kwatsopano: zida zovomerezeka za kompositi. Izi sizongochitika chabe; ndikusintha koyenera komwe kumayendetsedwa ndi kukwera kwa chidziwitso cha ogula komanso kupita patsogolo kwaukadaulo wamapaketi.
1. Kodi “Compostable Packaging” N'chiyani?
Choyamba, lingaliro lofunikira liyenera kumveketsedwa bwino: "compostable" sikufanana ndi "degradable" kapena "biobased". Ndi liwu laukadaulo lomwe lili ndi matanthauzidwe okhwima asayansi ndi miyezo yotsimikizira.
Njira Yasayansi: Kuyika kompositi kumatanthawuza njira yomwe zida za organic, pansi pamikhalidwe inayake (m'mafakitale opangira kompositi kapena makina apanyumba), zimaphwanyidwa ndi tizilombo toyambitsa matenda kukhala madzi, mpweya woipa, mchere wamchere, ndi biomass (humus). Izi sizisiya zotsalira zapoizoni kapena ma microplastics.
Zitsimikizo Zazikulu: Ndi zonena zosiyanasiyana pamsika, chiphaso cha chipani chachitatu ndikofunikira. Miyezo yodziwika bwino padziko lonse lapansi ndi:
*Chitsimikizo cha BPI: Muyezo wovomerezeka ku North America, kuwonetsetsa kuti zogulitsa ziphwanyidwa bwino m'malo opangira kompositi m'mafakitale.
*TUV OK kompositi HOME / INDUSTRIAL: Chitsimikizo chodziwika bwino ku Europe chomwe chimasiyanitsa pakati pa kompositi yakunyumba ndi mafakitale.
*AS 5810: Muyezo waku Australia wa compostability kunyumba, womwe umadziwika ndi zofunikira zake zolimba komanso chizindikiro chodalirika cha kuthekera kwa kompositi kunyumba.
Ngati mankhwala, monga matumba a zipper a ECOPRO, zomangira, kapena matumba opangira, amanyamula ziphaso zambiri zotere, zimatanthawuza kuti kupangidwa kwake kwazinthu ndi kusokonezeka kwake kwayesedwa mwamphamvu ndikutsimikiziridwa ndi mabungwe odziyimira pawokha, ndikupangitsa kuti ikhale yankho lodalirika lotsekeka.
2. The Core Materials Science: The Blending Art of PBAT, PLA, and Starch
Maziko a mapaketi ovomerezekawa nthawi zambiri sakhala chinthu chimodzi koma "kuphatikiza" kokonzedwa bwino kolinganiza magwiridwe antchito, mtengo, ndi compostability. Kapangidwe kameneka, makamaka pamakanema osinthika monga kukulunga, zikwama zogulira, ndi zoyika zofewa, ndiye dongosolo lakale la PBAT, PLA, ndi wowuma:
*PBAT (Polybutylene Adipate Terephthalate): Iyi ndi poliyesitala yopangidwa ndi petroleum koma yosawonongeka. Zimathandizira kusinthasintha, kusinthasintha, komanso kupanga mafilimu abwino, kumapereka kumverera ndi kulimba kofanana ndi filimu yachikhalidwe ya polyethylene (PE), kuthetsa vuto la brittleness la zipangizo zina zowona.
*PLA (Polylactic Acid): Amachokera ku kupesa kwa mbewu monga chimanga kapena chinangwa. Amapereka kuuma, kuuma, ndi zotchinga katundu. Pakuphatikiza, PLA imakhala ngati "mafupa," kupititsa patsogolo mphamvu zonse zakuthupi.
*Wowuma (Chimanga, Mbatata, ndi zina): Monga zodzaza zachilengedwe, zongowonjezwdwa, zimathandizira kuchepetsa mtengo ndikuwonjezera zomwe zili mu biobased ndi hydrophilicity ya zinthu, kuthandizira kulumikizidwa kwa tizilombo ndi kuyambitsa kuwonongeka koyambirira kwa kompositi.
PBAT / PLA / starch composite material ndi maziko omwe amapezeka kwambiri a certified compostable cling films, matumba a zipper, ndi kupanga matumba omwe amakwaniritsa miyezo monga BPI, TUV, ndi AS 5810. Kukonzekera kwake kumatsimikizira kuti kumapeto kwa moyo wake wothandiza, akhoza kulowa bwino mu kayendedwe ka zamoyo.
3. Chifukwa chiyani Chakudya Chakuofesi Ndi Chofunikira Kwambiri?
Kuwonjezeka kwa ma CD opangidwa ndi compostable pakati pa ogwira ntchito muofesi kumayendetsedwa ndi zinthu zomveka bwino zasayansi ndi chikhalidwe cha anthu:
*Zinyalala Zapakati ndi Kusanja: Maofesi am'maofesi nthawi zambiri amakhala ndi njira zoyendetsera zinyalala pakati. Ogwira ntchito akamagwiritsira ntchito kwambiri zoyikapo compostable, zimakhala zotheka kuti makampani agwiritse ntchito nkhokwe zosonkhanitsira kompositi, zomwe zimathandizira kulekanitsa magwero, kukonza kuyeretsa kwa zinyalala, komanso kupititsa patsogolo njira zopangira manyowa.
*Kufunika Kwapawiri Kwazabwino ndi Kukhazikika: Akatswiri amafunikira zolongedza zomwe zili zosindikizidwa, zotsikira, komanso zosunthika. Zopaka zamakono zopangira compostable (monga zikwama za zipi zoyimirira) tsopano zimakwaniritsa zofunikira izi pomwe zikuposa mapulasitiki achikhalidwe pazachilengedwe.
*Njira Yomveka Yamapeto a Moyo: Mosiyana ndi zinyalala zam'nyumba zomwazikana, makampani amatha kuyanjana ndi akatswiri opanga makina opangira zinthu kuti awonetsetse kuti zinyalala zomwe zasonkhanitsidwa zimatumizidwa kumalo oyenera, kutseka loop. Izi zimayang'ana chisokonezo cha wogula "chosadziwa komwe angachiponye," zomwe zimapangitsa kuti ntchitoyo ikhale yabwino kwambiri.
*Kuwonetsa ndi Kusokoneza Mawonekedwe: Maofesi ndi malo ochezera. Kusankha kosasunthika kwa munthu m'modzi kumatha kukhudza kwambiri anzake, kulimbikitsa zikhulupiriro zabwino zamagulu ndi zosankha zogula (mwachitsanzo, kugula zinthu zonse zokomera chilengedwe), potero kumakulitsa chidwi.
4. Kugwiritsa Ntchito Mwanzeru ndi Kuganiza Kwadongosolo
Ngakhale malingaliro akuyembekeza, kugwiritsa ntchito kwasayansi pakuyika kompositi kumafuna kuganiza kwamakina:
Sikuti Zopaka Zonse Za "Green" Zitha Kutayidwa Kulikonse: Ndikofunikira kusiyanitsa pakati pa zinthu zovomerezeka za "composting ya mafakitale" ndi za "composting yakunyumba." Phukusi la "compostable" loyikidwa molakwika muzobwezeretsanso pulasitiki wamba limakhala lodetsa.
Zomangamanga ndizofunikira: Kukulitsa phindu la chilengedwe la ma CD opangidwa ndi kompositi kumadalira kutukuka kwa malo opangira zosonkhanitsira kutsogolo ndikumapeto kopangira kompositi. Kuthandizira kulongedza koteroko kumatanthauzanso kuchirikiza ndi kuthandizira zopangira kompositi kwanuko.
Dongosolo Lofunika Kwambiri: Kutsatira mfundo za "Chepetsani, Gwiritsaninso Ntchito," "Compostable" ndi njira yabwino yothanirana ndi zinyalala zomwe sizingapeweke. Ndizoyenera kwambiri kulongedza zomwe zimakumana ndi zotsalira zazakudya ndipo zimakhala zovuta kuyeretsa (mwachitsanzo, zotengera zamafuta, filimu yotsatsira).
Mapeto
Kukwera kwa ma compostable chakudya kumayimira kuphatikizika kwa kupita patsogolo kwa sayansi yazinthu komanso kufunikira kwazachilengedwe kwa anthu akumatauni. Zimatanthawuza kuyesa kusintha kuchoka ku "linear economic" (make-use-dispose) kupita ku "chuma chozungulira." Kwa akatswiri akumatauni, kusankha ma CD opangidwa ndi certification odalirika monga BPI, TUV HOME, kapena AS5810-ndikuwonetsetsa kuti ikulowa m'njira yoyenera yopangira-ndi chizoloŵezi chogwirizanitsa zochita za tsiku ndi tsiku ndi zochitika zapadziko lonse lapansi. Ulendo wopita ku ziro zinyalala umayamba ndikumvetsetsa sayansi yamapaketi omwe ali m'manja ndipo umatheka chifukwa cha mgwirizano wadongosolo lonse la zinyalala m'deralo. Chisankho chomwe chimapangidwa pa nthawi ya nkhomaliro ndi pomwe pamakhala poyambira pakusintha kwadongosolo.
