Ibiciro byo kubaho byazamutse kwisi yose none bigira ingaruka mubice byose byubuzima bwabantu.
Ku bantu benshi, ibiciro byiyongera bishobora gusobanura ko gufata ikawa ubu bihenze kuruta mbere hose.Imibare yaturutse i Burayi yerekana ko igiciro cya kawa yo gufata cyiyongereyeho kimwe cya gatanu mu mwaka wabanjirije Kanama 2022 bitandukanye na 0.5% mu mezi 12 abanziriza.
Ibi birashobora gutuma abakiriya benshi bateka ikawa murugo aho kuyitegeka kugenda, tekinike yamenyekanye cyane mugihe cya Covid-19.Numwanya mwiza kubakoresha benshi gusubiramo ibyo bahisemo gufata ikawa murugo.
Kugira ngo wirinde gutandukanya abakiriya nibicuruzwa bitakaza vuba vuba, hagomba guhitamo gupakira ikawa neza.Roaster ikunze kubika ikawa yabo mumifuka yikawa yuzuye ifu kugirango ikomeze ubwiza bwibishyimbo.
Ibiciro n'ingaruka zibidukikije byiyi nzira, ariko, birashobora gutuma bikenerwa kuri roasteri kurusha izindi.
Ubwihindurize bwo gupakira
Aluminium foil isanzwe ikorwa muguterera ibisate bya aluminiyumu yashongeshejwe.
Aluminiyumu yazengurutswe muriyi nzira kugeza igihe ubugari bukenewe bugerweho.Irashobora kubyazwa umusaruro umwenda wa file hamwe nubunini buri hagati ya micrometero 4 na 150.
Mu myaka ya za 1900, ibiryo byubucuruzi nibipfunyika byifashishijwe aluminium.Ikigaragara ni uko kimwe mubikorwa byacyo byambere byari isosiyete ikora bombo yo mubufaransa Toblerone gupfunyika shokora.
Byongeye kandi, byabaye nk'igifuniko cy'isafuriya y'ibigori abakiriya bashobora kugura no gushyushya murugo kugirango bakore popcorn nshya "Jiffy Pop".Byongeye kandi, yamenyekanye cyane mugupakira amafunguro ya TV yagabanijwe.
Ifu ya aluminiyumu ikoreshwa cyane mugukora ibintu bikomeye, igice-gikomeye, kandi byoroshye gupakira muri iki gihe.Muri iki gihe, fili ikoreshwa kenshi kumurongo wa kawa yuzuye cyangwa yubutaka.
Mubisanzwe, ihindurwamo urupapuro rwicyuma cyoroshye cyane kandi igahuzwa nu gipfunyika cyo hanze gikunze kuba gikozwe muri plastiki, impapuro, cyangwa bioplastike nka aside polylactique.
Igice cyo hanze cyemerera kwihindura, nko gucapa umwihariko wa kawa imbere, mugihe urwego rwimbere rukora inzitizi.
Ifu ya aluminium yoroheje, ifite umutekano wo gukoresha ku biryo, ntishobora kwangirika byoroshye, kandi irinda urumuri n’ubushuhe.
Ariko hariho inzitizi nyinshi mugihe ukoresheje imifuka yikawa ikozwe neza.Kubera ko yacukuwe, aluminiyumu ifatwa nkumutungo muto amaherezo uzarangiza, ukazamura ikiguzi cyo gukoresha.
Byongeye kandi, iyo ifunitse cyangwa isenyutse, fayili ya aluminiyumu irashobora rimwe na rimwe gutakaza imiterere cyangwa kubona mikorosikopi.Iyo upakiye ikawa muri file, hagomba gushyirwaho valve itesha agaciro kuko umufuka ushobora kuba mwinshi.
Kugirango ukomeze uburyohe bwa kawa ikaranze kandi wirinde ko ibipfunyika bidaturika, dioxyde de carbone irekurwa nka kawa ikaranze ikawa igomba kwemererwa guhunga.
Ese imifuka yikawa ikeneye gutondekwa na file?
Gukenera gupakira byoroshye biziyongera hamwe nabatuye isi.
Bitewe no kuyikoresha no kuyigeraho, gupakira ikawa yoroheje nayo iteganijwe kubona izamuka ryibisabwa.
Ipaki ihindagurika nayo yangiza ibidukikije kuruta guhitamo guhatanira, hamwe nugupakira-ibicuruzwa biri munsi yikubye inshuro 5 kugeza 10.
Toni zirenga miliyoni 20 z'ibikoresho byo gupakira zishobora kuzigama muri EU yonyine niba ibigo byinshi byimukiye mubipfunyika byoroshye.
Rero, abatekamutwe batanga ibicuruzwa byangiza ibidukikije birashobora kwemeza abakiriya guhitamo ibicuruzwa byabo kuruta ibicuruzwa birushanwa.Icyakora, iperereza riherutse gukorwa na Greenpeace ryerekanye ko aho gutunganyirizwa ibintu, ibintu byinshi bitwikwa cyangwa bigatereranwa.
Ibi bivuze ko isake igomba gukoresha igihe kirekire cyo gupakira uko bashoboye.Nubwo mugihe file ari ibikoresho byingirakamaro mugutondekanya imifuka yikawa, hari ibibi bifite roasteri zishakisha ubundi buryo.
Isake nyinshi ihitamo gukoresha urwego rwimbere rwicyuma cya PET nicyuma cyo hanze gikozwe muri polyethylene (PE).Nyamara, ibifatika bikoreshwa kenshi muguhuza ibyo bice, bigatuma bidatandukana.
Kubera ko aluminiyumu ikoreshwa muri ubu buryo idashobora gutunganywa cyangwa kugarurwa, akenshi irangiza igatwikwa.
Acide polylactique (PLA) irashobora kuba amahitamo meza kubidukikije.Iyi bioplastique ikorwa mubishobora kuvugururwa nkibigori nibigori kandi nta burozi bufite.
Byongeye kandi, PLA irashobora kubora mugihe cyo gufumbira ifumbire mvaruganda kandi itanga inzitizi ikomeye kubushyuhe bwinshi, ubushuhe, nubushuhe.Ubuzima bwumufuka wa kawa burashobora kwiyongera mugihe cyumwaka mugihe PLA ikoreshwa mugutondekanya umufuka.
kubungabunga ibidukikije byangiza ibidukikije
Nubwo imifuka yikawa itondekanye neza ishobora kuba ifite ibyiza, abatekamutwe bafite ubundi buryo butandukanye bushobora gufasha gukomeza gushya.
Hano hari amahitamo menshi yangiza ibidukikije arahari, mugihe abatekamutwe bamenyesha abakiriya babo uburyo bwo kuyitwara neza.Kurugero, ikawa ikarito ihitamo ibipapuro byapakiwe na PLA igomba kugira inama abakiriya gushyira igikapu cyubusa muburyo bukwiye bwo gutunganya cyangwa nimero ya bin.
Roaster irashobora gushaka gukusanya imifuka yikawa ubwayo niba ibikoresho bitunganyirizwamo abaturanyi bidashoboye gutunganya ibi bikoresho.
Abakiriya barashobora kwakira ikawa ihendutse ivuye mu isake kugirango bagarure ikawa irimo ubusa.Roaster irashobora kohereza imifuka yakoreshejwe gusubira mubakora kugirango bongere kuyikoresha cyangwa kuyijugunya neza.
Byongeye kandi, kubikora bizemeza ko ibicuruzwa byo hanze bipfunyika hamwe nibikoresho byo gupakira, nka zipi na valve byangiza, bitandukanijwe neza kandi bitunganijwe.
Muri iki gihe abakoresha ikawa bafite ibyo bakeneye, kandi gupakira bigomba kuramba.Abakiriya bakeneye uburyo bwo kubika ikawa yabo ifite ingaruka nkeya zishoboka kubidukikije, abatekamutwe bagomba gutanga.
Kuri CYANPAK, dutanga amahitamo yijana yijana yama kawa yongeye gutunganyirizwa ibisubizo bivuye mubikoresho bishobora kuvugururwa nkimpapuro za Kraft, impapuro z'umuceri, cyangwa ibipapuro byinshi bya LDPE bipfunyika hamwe nibidukikije byangiza ibidukikije bya PLA, byose bigabanya imyanda kandi bigashyigikira ubukungu bwizunguruka.
Byongeye kandi, dutanga abatekamutwe ubwisanzure bwo guhanga tubareka bakarema imifuka yabo ya kawa.
