Pafupifupi matani 8.3 biliyoni apulasitiki apangidwa kuyambira pomwe mafakitale adayamba kupangidwa m'ma 1950.
Malinga ndi kafukufuku wa 2017, yemwe adapezanso kuti 9% yokha ya pulasitiki iyi imasinthidwanso moyenera, ndi momwe zilili.12% ya zinyalala zomwe sizingabwezeretsedwenso zimatenthedwa, ndipo zotsalazo zimawononga chilengedwe potayidwa m'matayipilo.
Yankho labwino lingakhale kuchepetsa kugwiritsa ntchito pulasitiki kamodzi kapena kupanga zoyikapo kuti zikhale zokhazikika chifukwa kupewa kuyika kwamtundu wamba sikotheka nthawi zonse.
Mapulasitiki achikhalidwe akusinthidwa ndi zinthu zomwe zingagwiritsidwenso ntchito kapena zachilengedwe, monga zopaka khofi wothira manyowa, m'mafakitale ambiri, kuphatikiza makampani apadera a khofi.
Chidebe cha khofi wopangidwa ndi kompositi, komabe, chimakhala ndi zinthu zachilengedwe zomwe zimawola pakapita nthawi.Anthu ena ogulitsa khofi akuda nkhawa ndi moyo wa alumali wa mankhwalawa.Komabe, matumba a khofi opangidwa ndi kompositi ndi amphamvu kwambiri komanso othandiza pakusunga nyemba za khofi zikasungidwa m'malo oyenera.
Phunzirani zambiri za kukulitsa moyo wa alumali wapaketi yophatikizika ya khofi yowotcha ndi malo ogulitsa khofi.
Kodi mapaketi a khofi omwe ali ndi kompositi ndi chiyani?
Mwachikhalidwe, zida zomwe zidzawola m'magulu awo achilengedwe pansi pamikhalidwe yoyenera zimagwiritsidwa ntchito popanga khofi wopangidwa ndi kompositi.
Nthawi zambiri, amapangidwa ndi zinthu zongowonjezeranso monga nzimbe, chimanga, ndi chimanga.Ziwalozi zikatha, sizikhala ndi zotsatirapo zoyipa pa chilengedwe.
Mapaketi opangidwa ndi kompositi, omwe nthawi zambiri amapangidwa ndi zinthu zachilengedwe, atchuka kwambiri pazakudya ndi zakumwa.Makamaka, nthawi zambiri amagwiritsidwa ntchito kuyika ndikugulitsa khofi ndi owotcha apadera komanso malo odyera khofi.
Kuyika kwa kompositi ndi kosiyana ndi mitundu ina ya bioplastic chifukwa imabwera mosiyanasiyana, mawonekedwe, ndi mapangidwe.
Mawu akuti "bioplastic" amatanthauza zinthu zosiyanasiyana.Itha kugwiritsidwa ntchito pofotokoza zinthu zapulasitiki zopangidwa kuchokera kuzinthu zachilengedwe zomwe zimatha kusinthidwanso, kuphatikiza mafuta amasamba ndi mafuta.
Polylactic acid (PLA), compostable bioplastic, imakonda kwambiri makampani a khofi.Izi zili choncho chifukwa amathandizira kuchepetsa kagayidwe ka kaboni ka bizinesi pongosiya madzi, mpweya woipa, ndi biomass pamene atayidwa moyenera.
Mwachizoloŵezi, shuga wothira kuchokera ku zomera zowuma kuphatikizapo chimanga, beet, ndi chinangwa cha chinangwa akhala akugwiritsidwa ntchito popanga PLA.Kuti apange PLA pellets, ndi yotengedwa shuga ndi thovu mu lactic acid ndiyeno kudutsa njira polymerization.
Ma pellets awa atha kugwiritsidwa ntchito kupanga zinthu zina, kuphatikiza mabotolo ndi zida zamankhwala zomwe zimatha kuwonongeka ngati zomangira, zikhomo, ndi ndodo, poziphatikiza ndi poliyesitala ya thermoplastic.
PLA a chotchinga makhalidwe ndi chibadidwe kutentha kukana kupanga izo zinthu abwino kwa ma CD khofi.Kuphatikiza apo, imapereka chotchinga cha okosijeni chomwe chimagwira ntchito ngati thermoplastics wamba.
Zoopsa zazikulu za kutsitsimuka kwa khofi ndi mpweya ndi kutentha pamodzi ndi chinyezi ndi kuwala.Chotsatira chake, kulongedza kuyenera kulepheretsa zinthu izi kusokoneza komanso kuwononga nyemba mkati.
Zotsatira zake, matumba ambiri a khofi amafunikira magawo angapo kuti ateteze ndikusunga khofi watsopano.Pepala la Kraft ndi PLA liner ndizomwe zimaphatikizidwira kwambiri pamapangidwe a khofi opangidwa ndi kompositi.
Pepala la Kraft ndilosavuta komanso limakwaniritsa mawonekedwe a minimalist omwe masitolo ambiri a khofi amakonda kusankha.
Mapepala a Kraft amathanso kuvomereza inki zokhala ndi madzi ndikugwiritsidwa ntchito munjira zamakono zosindikizira za digito, zonse zomwe ndi zokonda zachilengedwe.
Kuyika kwa kompositi sikungakhale koyenera kwa mabizinesi omwe akufuna kusunga zinthu zawo zatsopano kwa nthawi yayitali, koma ndi abwino kwa khofi wapadera.Izi ndichifukwa choti PLA igwira ntchito mpaka chaka chimodzi chimodzimodzi ndi ma polima wamba.
N'zosadabwitsa kuti okazinga ndi malo odyera khofi akufunitsitsa kugwiritsa ntchito khofi wa compostable pagawo lomwe ogula nthawi zambiri amaika patsogolo kukhazikika.
Kodi compostable coffee package imatha nthawi yayitali bwanji?
Choyikapo chomwe chimakhala ndi kompositi chimapangidwa m'njira yoti zinthu zina zitha kuwola.
Imafunika malo oyenera a tizilombo toyambitsa matenda, mpweya ndi chinyezi, kutentha, ndi nthawi yayitali kuti iwonongeke.
Malingana ngati ikusungidwa mozizira, youma, ndi mpweya wabwino, idzapitirizabe kukhala yamphamvu komanso yokhoza kuteteza nyemba za khofi.
Chifukwa chake, mikhalidwe yofunikira kuti iwonongeke iyenera kuyang'aniridwa mosamala.Chifukwa cha izi, zotengera zina za kompositi sizingakhale zoyenera kupanga kompositi kunyumba.
M'malo mwake, zotengera za khofi zokhala ndi mizere ya PLA ziyenera kutayidwa mu chidebe choyenera chobwezeretsanso ndikupita kumalo oyenera.
Mwachitsanzo, UK tsopano ili ndi zida zopitilira 170 zopangira kompositi zamafakitale.Dongosolo loti makasitomala abweze zonyamula zotayidwa kumalo owotcha kapena khofi ndi pulogalamu ina yomwe ikukula kwambiri.
Kenako eni ake atha kutsimikizira kuti atayidwa bwino.Origin Coffee ndi imodzi mwazowotcha zaku UK zomwe zimapambana pa izi.Zapangitsa kuti zikhale zosavuta kusonkhanitsa zida zake zopangira zinthu zomwe zitha kuwonongeka ndi mafakitale kuyambira mu 2019.
Kuphatikiza apo, pofika mu June 2022, imagwiritsa ntchito 100% yokha yonyamula khofi kunyumba, ngakhale kusonkhanitsa kwa kerbside sikutheka ndi izi.
Kodi okazinga angapangitse bwanji kuti khofi yawo ya kompositi ikhale yayitali?
M'malo mwake, khofi wa compostable ayenera kusunga khofi wowotcha kwa miyezi isanu ndi inayi mpaka khumi ndi iwiri popanda kuwonongeka pang'ono.
Matumba a khofi okhala ndi compostable PLA awonetsa mawonekedwe apamwamba kwambiri komanso kusungidwa kwatsopano pamayesero poyerekeza ndi ma CD a petrochemical.
Kwa nthawi ya masabata 16, olembetsa a Q ovomerezeka adapatsidwa ntchito yoyesa khofi wosungidwa m'matumba amitundu yosiyanasiyana.Analangizidwanso kupanga makapu akhungu ndikulemba kutsitsimuka kwa mankhwalawa potengera zingapo zofunika.
Malinga ndi zomwe zapeza, zosakaniza za kompositi zimasunga kununkhira ndi fungo labwino kwambiri.Iwo adawonanso kuti acidity idachepa pang'ono panthawiyi.
Zofunikira zosungiramo zofananira zimagwiranso ntchito pamapaketi a khofi opangidwa ndi kompositi monga momwe amachitira khofi.Iyenera kusungidwa pamalo ozizira komanso owuma kuti zisawonongeke ndi dzuwa.Owotcha ndi mabizinesi a khofi ayenera kukumbukira chilichonse mwazinthu izi posunga matumba a khofi.
Komabe, matumba okhala ndi PLA amafunikira chisamaliro chapadera chifukwa amatha kutsika mwachangu pamikhalidwe iyi.
Kuyika kwa kompositi kumatha kuthandizira zolinga za kampani ndikukopa makasitomala ochulukirachulukira osamala zachilengedwe ngati atasamalidwa bwino.
Chinsinsi apa, monga ndi zina zambiri za khofi wogulitsa, ndikudziwitsa makasitomala za machitidwe oyenera.Kuti khofi ikhale yatsopano, owotcha ali ndi mwayi wosindikiza malangizo amomwe mungasungire matumba a khofi opangidwa ndi kompositi.
Kuphatikiza apo, amatha kulangiza makasitomala momwe angagwiritsire ntchito matumba awo okhala ndi mizere ya PLA powawonetsa komwe angatayire.
Ku Cyan Pak, timapereka zotengera zachilengedwe zowotcha khofi ndi malo ogulitsira khofi omwe angateteze khofi wanu kuti asawonekere ndikuwonetsa kudzipereka kwanu pakukhazikika.
Mpunga wathu wambirimbiri kapena zikwama zamapepala za kraft zimagwiritsa ntchito malayiti a PLA kuti apange zotchinga zowonjezera mpweya, kuwala, kutentha, ndi chinyezi kwinaku akusunga zomwe phukusili likhoza kubwezerezedwanso komanso compostable.
Lumikizanani nafe kuti mumve zambiri za phukusi la khofi la kompositi.
