Ukusika ngokhuni kwenziwa ngokhuni lwemvelo (isb. i-birch, uqalo, i-oki), ngokuvamile kusuka emithonjeni eqhubekayo. Inqubo yayo yokukhiqiza ilula futhi ngokuvamile ihlanganisa izinyathelo ezinjengokusika izinkuni, ukubumba, ukugawula isihlabathi nokupholisha. Izinhlobo ezahlukene zokusika ngokhuni, njenge-birch, bamboo kanye ne-oki cutlery, ngayinye inezici zayo mayelana nokuqina, isisindo nokusanhlamvu. I-birch cutlery ilula futhi ihlala isikhathi eside; i-bamboo cutlery ilula kodwa iqinile kancane; futhi i-oki cutlery iyona enamandla kakhulu futhi ihlala isikhathi eside, kodwa futhi isisindo esindayo.
Izinzuzo eziyinhloko zokusika ngokhuni ukubola kwayo, ukusetshenziswa kwezinsiza ezivuselelekayo kanye nokungabikho kwamakhemikhali ayingozi.
I-plastic cutlery yenziwe ngama-polymers asekelwe ku-petroleum (isb. i-polypropylene, i-polystyrene). Inqubo yokukhiqiza iyinqubo yezimboni eyinkimbinkimbi ehilela i-polymerization yezinto ezingavuthiwe, ukubumba umjovo, ukupholisa nokusikwa. I-polypropylene cutlery ngokuvamile ihlala isikhathi eside futhi imelana nokushisa; i-polystyrene cutlery ishibhile kodwa iqinile futhi ayikwazi ukumelana nokushisa.
Ububi obuyinhloko bezinto zokusika zepulasitiki ukuthi aziboli, zibangela ukungcoliswa kwepulasitiki okuphawulekayo, futhi zingakhipha amakhemikhali ayingozi.
Ukusika ngokhuni kunikeza izinzuzo ezibalulekile zemvelo. Ukuwohloka kwayo kwemvelo kuyivimbela ekungcoliseni indawo ezungezile ngokuhamba kwesikhathi, kuyilapho ukusika kwepulasitiki kuhlala amakhulu eminyaka noma ngaphezulu. Ngaphezu kwalokho, izinto zokusika ngokhuni zisebenzisa izinsiza ezivuselelekayo, kuyilapho ukusika kwepulasitiki kuncike emithonjeni ye-petroleum engavuseleleki. Ukukhetha izinto zokusika ngokhuni kusiza ukunciphisa udoti wepulasitiki nokuvikela imvelo.
Ukusika ngokhuni kuphephe kakhudlwana empilweni yomuntu njengoba kwenziwa ngokhuni lwemvelo futhi akunawo noma ambalwa kakhulu amakhemikhali ayingozi. Ngakolunye uhlangothi, izinto zokusika zepulasitiki zingase zikhiphe amakhemikhali ayingozi, njenge-Bisphenol A, phakathi nokukhiqizwa nokusetshenziswa, okungase kube yingozi empilweni yomuntu.
Izinto zokusika ngokhuni aziqinile kangako futhi zikhubazeka kalula noma zilinyazwe umswakama. I-plastic cutlery ihlala isikhathi eside futhi ayijwayele ukuguga noma ukulimala, kodwa ijwayele ukuklwebheka. Izinto zokusika ngokhuni zidinga ukugezwa futhi zomiswe ngesikhathi ngemva kokusetshenziswa ukuze zelule ukuphila kwazo.
Nakuba izindleko zokuqala zokusika izitsha zokhuni zingase zibe phezulu kunezisika zepulasitiki, ngokuhamba kwesikhathi, ukusika ngokhuni kubiza kakhulu uma kubhekwa izindleko zokulahla izinto zokusika zepulasitiki kanye nomonakalo okuwudalayo endaweni ezungezile. Emabhizinisini, ukukhetha izinto ezisimeme zokhuni kuthuthukisa isithombe somkhiqizo futhi kuhehe abathengi abaqaphela imvelo.
Ukusika ngokhuni kunokuthungwa kwemvelo kanye nobuhle obuhambisana kakhulu nokuphishekela imvelo yesimanje kanye nemvelo. Ngakolunye uhlangothi, ukusika kwepulasitiki kuvame ukushibhile futhi kuntula izinto zobuhle.
I-plastic cutlery inenzuzo yokuba lula ngenxa yokusetshenziswa kwayo okukodwa futhi kulula ukusabalalisa imvelo. Ukusika ngokhuni akulula kangako njengoba kudinga ukuphinda kusetshenziswe futhi kuhlanzwe.
I-plastic cutlery, ikakhulukazi i-polypropylene cutlery, ngokuvamile inokumelana nokushisa okungcono futhi iyakwazi ukumelana nokudla okuphezulu kwezinga lokushisa. Izinto zokusika ngokhuni azikwazi ukumelana nokushisa futhi azifanele ukuphakela ukudla okushiselwe ngokweqile.
I-dinnerware yokhuni ilungele izikhathi ezahlukahlukene:
Imikhosi (imishado, amaphathi, amaphiknikhi): Izinto zokusika ngokhuni zihambisana nemvelo futhi zinhle, zilungele zonke izinhlobo zemikhosi.
Ukusetshenziswa kwansuku zonke (ikhaya, ihhovisi, usohambeni): Izinto zokusika ngokhuni zilula futhi azinzile, zilungele ukusetshenziswa kwansuku zonke.
Ukusetshenziswa kwezentengiselwano (izindawo zokudlela, ukudla, amakhefi): Indawo yokusika ngokhuni iyonga futhi iheha amakhasimende aqaphela imvelo futhi ithuthukisa isithombe somkhiqizo.
Umbuzo: Ungakwazi i izinto zokusika izinkuni kufanele ziwashwe futhi ziphinde zisetshenziswe?
A: Yebo. I-wood cutlery ihloselwe ukulahlwa futhi inconywa ukusetshenziswa okukodwa kuphela.
Q: Kuthatha isikhathi esingakanani ukuthi isigaxa sezinkuni\/ipulastiki\/ipulastiki evundisiwe ingcoliswe endaweni yokulahla imfucumfucu?
IMP: Okwamanje, alukho ucwaningo oluqinisekisa isikhathi esiqondile sokugawula izinkuni ukuze kwehliswe isithunzi endaweni yokulahla udoti. Njengoba izindawo zokulahla imfucumfucu zenzelwe ukuthi imfucuza yonakale kancane kakhulu kunesimo semvelo, kuzothatha isikhathi eside nokho, lokho kumquba ongasemva kwendlu yakho!
Njengomkhiqizo wemvelo, i-birch cutlery ingaqhathaniswa nemfucuza yokudla. Imfucuza yokudla ilinganiselwa ukuthi izobola phakathi nezinyanga eziyisi-6-24 endaweni yokulahla imfucumfucu.
Ipulasitiki ingathatha iminyaka eyi-10-100 endaweni yokulahla imfucuza. Okubizwa ngokuthi “amapulasitiki avundisiwe” awehlisi kalula endaweni yemvelo futhi kuphephile ukucabanga ukuthi isikhathi sokucekela phansi endaweni yokulahla imfucumfucu siseduze nesepulasitiki, kunesokusika izinkuni.
Q: Ingabe ukusebenzisa izinkuni kulimaza izihlahla zezihlahla?
IMP: Kuwukungaqondi okuvamile ukuthi imikhiqizo yezinkuni ilimaza izihlahla zezihlahla. Izinkuni zingenye yezinto ezisimeme kakhulu ezingasetshenziswa. Imunca i-CO2 ngenkathi ikhula futhi idale izindawo zokuhlala zezilwane zasendle. Kubalulekile nokho ukusebenzisa izinto ezingavuthiwe ezivela emahlathini aphethwe ngendlela efanele.
Q: Zingakanani izinkuni ezidingekayo ukwenza isigaxa?
A: Inqubo yokukhiqiza yokusika izinkuni isebenza kahle kakhulu. Isihlahla esisodwa esilingana nesigxobo socingo singakhiqiza izingcezu zokusika ezingaba ngu-20 000.
Ukusika ngokhuni nepulasitiki kunezinzuzo kanye nokubi. Ukusika ngokhuni kunezinzuzo ezibalulekile mayelana nokuvikelwa kwemvelo kanye nempilo nokuphepha, kuyilapho ukusika kwepulasitiki kuphakeme ngokufaneleka nokuqina. Ukukhethwa kwezinto zokusika kuncike esimweni esithile sokusetshenziswa kanye nokuthandwa komuntu siqu. Kodwa-ke, uma kucatshangelwa umthelela wesikhathi eside wemvelo nempilo, ukusika ngokhuni kuyisinqumo esimeme kakhudlwana.
