Kuthatha isikhathi esingakanani ukupakishwa kwekhofi elivundisiwe?

Ilinganiselwa ezigidini eziyizinkulungwane ezingama-8.3 ​​amathani epulasitiki akhiwe kusukela ukukhiqizwa kwezimboni kwaqala ngawo-1950.

Ngokocwaningo lwango-2017, oluphinde lwathola ukuthi u-9% kuphela walo pulasitiki ugaywa kabusha ngendlela efanele, lokhu kunjalo.U-12% kadoti ongakwazi ukugaywa kabusha uyashiswa, futhi osele ungcolisa imvelo ngokulahlwa ezindaweni zokulahla imfucumfucu.

Impendulo ekahle kungaba ukunciphisa ukusetshenziswa kwepulasitiki okukodwa noma ukwenza izinto zokupakisha zisimame ngoba ukugwema izinhlobo ezijwayelekile zokupakisha akwenzeki ngaso sonke isikhathi.

Amapulasitiki endabuko athathelwa indawo yizinto ezingasetshenziswa kabusha noma ezivumelana nemvelo, okufana nokupakishwa kwekhofi okuvundisiwe, ezimbonini eziningi, okuhlanganisa imboni yekhofi ekhethekile.

Isiqukathi sekhofi elivundisiwe, nokho, siqukethe izinto eziphilayo ezibola ngokuhamba kwesikhathi.Abanye abantu embonini yekhofi bakhathazekile ngempilo yeshalofu yomkhiqizo ngenxa yalokho.Kodwa-ke, izikhwama zekhofi ezivundisiwe zinamandla ngendlela emangalisayo futhi zisebenza kahle ekulondolozeni ubhontshisi wekhofi uma zigcinwe endaweni efanele.

Funda kabanzi mayelana nokwelula impilo yeshalofu yokupakishwa kwekhofi elivundisiwe lama-roasters nezitolo zekhofi.

Kuyini ukupakishwa kwekhofi okuvundisiwe?

Ngokwesiko, izinto ezizobola zibe izingxenye zazo eziphilayo ngaphansi kwezimo ezifanele zisetshenziselwa ukwenza ukupakishwa kwekhofi okuvundisiwe.

Ngokuvamile, ikhiqizwa ngezinsiza ezivuselelekayo njengomoba, isitashi sommbila, nommbila.Uma sezihlakaziwe, lezi zingxenye azinayo imiphumela emibi emvelweni.

Ukupakishwa kwe-Compostable, okwakhiwa kakhulu ngezinto eziphilayo, sekuthole ukuthandwa emkhakheni wokudla neziphuzo.Ngokuphawulekayo, ngokuvamile isetshenziselwa ukupakisha nokudayisa ikhofi ngama-roasters akhethekile namakhefi ekhofi.

Ukupakishwa okuhlanganisiwe kuhlukile kwezinye izinhlobo ze-bioplastics ngoba iza ngobukhulu obuhlukahlukene, amafomu, kanye nemiklamo.

Igama elithi "bioplastic" libhekisela ezintweni ezihlukahlukene.Ingasetshenziselwa ukuchaza imikhiqizo yepulasitiki eyenziwe ngemithombo ye-biomass evuselelekayo, okuhlanganisa amafutha emifino namafutha.

I-Polylactic acid (PLA), i-compostable bioplastic, ithandwa kakhulu embonini yekhofi.Lokhu kungenxa yokuthi basiza ukwehlisa i-carbon footprint yebhizinisi ngokushiya ngemuva amanzi, isikhutha, kanye ne-biomass lapho kulahlwa ngokufanelekile.

Ngokwesiko, ushukela ovutshiwe ovela ezitshalweni zesitashi ezihlanganisa ummbila, isithombo sebhitrudi, nama-pulps omdumbula asetshenziselwe ukwenza i-PLA.Ukuze udale ama-pellets e-PLA, ushukela okhishiwe uvutshelwa ube yi-lactic acid bese udlula inqubo ye-polymerization.

Lawa ma-pellets angasetshenziswa ukudala imikhiqizo eyengeziwe, okuhlanganisa amabhodlela kanye nemishini yezokwelapha engaboli kahle njengezikulufu, izikhonkwane, nezinduku, ngokuzihlanganisa ne-thermoplastic polyester.

Izimfanelo zokuvimbela i-PLA kanye nokumelana nokushisa okungokwemvelo kuyenza ibe into efanelekile yokupakishwa kwekhofi.Ukwengeza, inikeza umgoqo we-oxygen osebenza kahle njenge-thermoplastics evamile.

Izingozi eziyinhloko zokusha kwekhofi umoya-mpilo nokushisa kanye nomswakama nokukhanya.Ngenxa yalokho, ukupakishwa kufanele kuvimbele lezi zakhi ukuthi zingabe nomthelela futhi ziwohloke ubhontshisi ngaphakathi.

Ngenxa yalokho, izikhwama zekhofi eziningi zidinga izendlalelo eziningi ukuze zivikele futhi zigcine ikhofi lilisha.Iphepha le-Kraft kanye ne-PLA liner yinhlanganisela yezinto ejwayelekile kunazo zonke yokupakishwa kwekhofi evundisiwe.

Iphepha le-Kraft lihlanganiswa ngokuphelele futhi lihambisana nesitayela se-minimalist izitolo eziningi zekhofi ezikhetha ukukhetha.

Iphepha le-Kraft lingase futhi lamukele o-inki abasekelwe emanzini futhi lisetshenziswe kumasu anamuhla okuphrinta edijithali, womabili avumelana kakhulu nemvelo.

Ukupakishwa okuvundisiwe kungase kungafaneleki kumabhizinisi afuna ukugcina imikhiqizo yawo iyintsha isikhathi eside, kodwa ilungele ikhofi elikhethekile.Lokhu kungenxa yeqiniso lokuthi i-PLA izosebenza isikhathi esingangonyaka ngokufana ncamashi nama-polymer avamile.

Akumangazi ukuthi ama-roasters namakhefi ekhofi azimisele ukusebenzisa ukupakishwa kwekhofi okuvundisiwe emkhakheni lapho abathengi ngokuvamile bebeka phambili ukusimama.

Ukupakishwa kwekhofi elivundisiwe kuzohlala isikhathi esingakanani?

Ukupakisha okuvundisiwe kwenziwa ngendlela yokuthi izimo ezithile kuphela ezizokwenza ukuthi abole.

Idinga indawo efanele ye-microbiological, amazinga omoya-mpilo kanye nomswakama, ukufudumala, kanye nobude besikhathi eside ukuze ibole.

Uma nje igcinwe ipholile, yomile, futhi inomoya omuhle, izoqhubeka inamandla futhi ikwazi ukuvikela ubhontshisi wekhofi.

Ngenxa yalokho, izimo ezidingekayo ukuze wehlise izinga kufanele zilawulwe ngokucophelela.Ngenxa yalokhu, ukupakishwa okuthile okuvundisiwe kungase kungafaneleki ukwenza umquba ekhaya.

Kunalokho, iphakethe lekhofi elivundisiwe elinemigqa ye-PLA kufanele ilahlwe esitsheni esifanele sokugaywa kabusha bese liyiswa endaweni efanele.

Isibonelo, i-UK manje inezindawo zokuhlanganisa izimboni ezingaphezu kuka-170.Ilungiselelo lokuthi amakhasimende abuyisele amaphakheji alahliwe endaweni yokosa noma esitolo sekhofi kungolunye uhlelo oluthola ukuduma.

Abanikazi bangaqinisekisa-ke ukuthi balahlwe ngendlela efanele.I-Origin Coffee iyindawo eyosiwe yase-UK ehamba phambili kulokhu.Kwenze kwaba lula ukuqoqa izingxenye zayo zokupakisha ezibolayo ngokwezimboni kusukela ngo-2019.

Ukwengeza, kusukela ngoJuni 2022, isebenzisa kuphela i-100% yephakheji yekhofi yasekhaya ebolayo, nakuba amaqoqo e-kerbside awakwenzeka ngalokhu.

Abagazingi bangenza kanjani iphakethe labo lekhofi elivundisiwe lihlale isikhathi eside?

Empeleni, ukupakishwa kwekhofi elivundisiwe kufanele kukwazi ukulondoloza ikhofi eligazingiwe izinyanga eziyisishiyagalolunye kuya kweziyishumi nambili ngaphandle kokuwohloka okuncane noma okungekho kwekhwalithi.

Izikhwama zekhofi ezinomugqa we-PLA ezivundile zibonise izici eziphakeme zesithiyo kanye nokugcinwa okusha ekuhlolweni okuqhathaniswa nokupakishwa kwe-petro-chemical.

Esikhathini esingamaviki angu-16, abafundi bebanga le-Q abanelayisensi banikezwe umsebenzi wokuhlola amakhofi agcinwe ezikhwameni ezihlukahlukene.Baphinde bayalwa ukuthi benze izinkomishi eziyimpumputhe futhi baphawule ubusha bomkhiqizo ngokusekelwe kwinani lezimpawu ezibalulekile.

Ngokwalokho okutholakele, izinto ezifakwa esikhundleni se-compostable zigcina ukunambitheka nephunga elimnandi noma elingcono.Baphinde baqaphela ukuthi i-acidity yehla ngokulambisa ngaleso sikhathi.

Izidingo ezifanayo zesitoreji zisebenza emaphaketheni ekhofi avundisiwe njengoba enza ekhofini.Kufanele igcinwe ingangeni elangeni endaweni epholile neyomile.Amabhizinisi okosa nekhofi kufanele akhumbule ngayinye yalezi zakhi lapho egcina noma yiziphi izikhwama zekhofi.

Kodwa-ke, izikhwama ezinomugqa we-PLA zidinga ukunakwa okukhethekile njengoba zingehlisa isithunzi ngokushesha ngaphansi kwanoma yiziphi zalezi zimo.

Ukupakishwa okune-Compostable kungasekela izinhloso zokusimama zenkampani futhi kukhange inani elandayo lamakhasimende aqaphela imvelo uma inakekelwa kahle.

Okubalulekile lapha, njengezinye izici eziningi zekhofi lokudayisa, ukwazisa amakhasimende ngezinqubo ezifanele.Ukuze ugcine ikhofi lilisha, abarosa banenketho yemiyalelo yokuphrinta ngokwedijithali yokuthi ugcina kanjani izikhwama zekhofi ezivundisiwe.

Ukwengeza, bangakwazi ukweluleka amakhasimende ukuthi bangagaya kabusha kanjani futhi kuphi izikhwama zabo ezinomugqa we-PLA ngokubakhombisa ukuthi bazilahle kuphi.

Kwa-Cyan Pak, sihlinzeka ngamaphakheji avumelana nemvelo kwabagazingi bekhofi nezitolo zekhofi ezizovikela ikhofi lakho ekuchayekeni ekukhanyeni futhi zibonise ukuzinikela kwakho ekuzinzeni.

Irayisi yethu ye-multilayer noma izikhwama zephepha ze-kraft zisebenzisa i-PLA laminates ukuze zenze izithiyo ezengeziwe kumoya-mpilo, ukukhanya, ukushisa, kanye nomswakama ngenkathi igcina izimfanelo zephakheji ezisebenziseka kabusha nezivundisekayo.

Xhumana nathi ukuze uthole imininingwane eyengeziwe mayelana nokupakishwa kwekhofi okuvundisiwe.
