Ukuvamile kwezinye izinto ezinokuthi zihlukaniswe kanye nezinto ezingaphansi kwesibhonti zokudla kuyisisekelo sokubhekana ngezinye izinto ezinokuthi zihlukaniswe kanye nezinto ezingaphansi kwesibhonti zokudla futhi ukubhekana nokuphatha kwezinye izinto ezinokuthi zihlukaniswe kanye nezinto ezingaphansi kwesibhonti zokudla, okuyisisekelo sokubhekana ngezinye izinto ezinokuthi zihlukaniswe kanye nezinto ezingaphansi kwesibhonti zokudla futhi ukubhekana nokuphatha kwezinye izinto ezinokuthi zihlukaniswe kanye nezinto ezingaphansi kwesibhonti zokudla.

Izinkonteynatha zebhola zihambelana ngezinkotho zepaperi ngokwesithembiso sezindawo zokuzisa?

Izinkonteynha zebhola zezinto zokudla nezinye ezibhalwe ngemithi zinamathuba amabili okususela kwezinkinga zokugcina izulu, noma kubalulekile ukuthi ziyisiphi isikhundla esisetshenziswa kulo nokuthi yiziphi izindawo zokubalwa kwemvelo. Izipaki zemithi zisebenza izinto ezingenakwazi ukuzalwa futhi zihlupheka ngokuzenzakale, kodwa zidinga ukuthi zibe nzima kakhulu ukuze bafanele ukuthi baphatha izinto zokudla ngokwesibonelo, futhi zanikezwa iplastik noma i-wax ukuze bakhanyise amandla okukhanya okufanele ukuthi baphatha izinto zokudla, futhi zidinga amanzi nama-enerji amaningi ekuphleni kwazo. Iplastik ibonakala kakhulu ngokusebenzisa izinto ngokunzima kakhulu futhi ngokuthi ibe nzima kakhulu ukuze bakhanyise amandla okukhanya nokuthi ibe nzima kakhulu, kodwa ibasekela emithilini yezinsizakalo zokuphatha izinto zokudla ngokwesibonelo, futhi ibe yisikhathi eside ekhaya uma akwenzekanga ukuthi kubuyiselwe ngokuphelele. Ukubalwa kwezinye izindawo zokuphatha izinto zokudla kubonisa ukuthi iplastik ibonakala kakhulu ngokuthi ibe nzima kakhulu ngokwesibonelo sokukhanya nokusebenzisa izinto ngokunzima kakhulu, ngakho-ke ipaper ibonakala kakhulu ngokuthi ibe nzima kakhulu ngokwesibonelo sokukhanya uma kudinga ukuthi kubuyiselwe ngokuphelele.
