Biodegradable futhi Compostable

Incazelo Nokusetshenziswa Kabi

I-biodegradable kanye ne-compostable ngokuvamile isetshenziswa ngokushintshana ukuchaza ukuwohloka kwezinto eziphilayo ezimweni ezithile.Kodwa-ke, ukusetshenziswa kabi kwe-"biodegradable" ekukhangiseni kuye kwaholela ekudidekeni phakathi kwabathengi.Ukubhekana nalokhu, i-BioBag isebenzisa igama elithi “compostable” emikhiqizweni yethu eqinisekisiwe.

I-Biodegradability

I-Biodegradability isho ikhono lempahla lokonakala, ukukhiqiza i-CO₂, H₂O, i-methane, i-biomass, nosawoti wamaminerali.Ama-microorganisms, ikakhulukazi awondliwa udoti wezinto eziphilayo, aqhuba le nqubo.Kodwa-ke, leli gama alinakho ukucaciswa, njengoba zonke izinto ekugcineni ziwohloka, okugcizelela isidingo sokucacisa indawo ehloselwe ukuwohloka kwemvelo.

I-Compostability

Ukwenza umquba kuhilela ukugaya kwe-microbial ukudiliza udoti wemvelo ube umquba, onenzuzo ekuthuthukiseni umhlabathi kanye nokuvundisa.Ukushisa okuphezulu, amanzi, nomoya-mpilo kuyadingeka kule nqubo.Ezingqungqutheleni zikadoti wezinto eziphilayo, amagciwane amaningi adla izinto zokwakha, aziguqule zibe umquba.Ukuvundisa okugcwele kudinga ukubambelela ezimisweni eziqinile ezifana ne-European Norm EN 13432 kanye ne-US Standard ASTM D6400, okuqinisekisa ukubola okuphelele ngaphandle kwezinsalela eziyingozi.

Amazinga Omhlaba

Ngaphandle kwe-European Standard EN 13432, amazwe ahlukahlukene anemikhuba yawo, okuhlanganisa i-US Standard ASTM D6400 kanye ne-Australian Norm AS4736.Lawa mazinga asebenza njengezilinganiso zabakhiqizi, izinhlangano ezilawulayo, izindawo zokwenza umquba, izikhungo zokunikeza izitifiketi, nabathengi.

Imibandela Yezinto Ezihlanganiswayo

Ngokusho kwe-European Standard EN 13432, izinto ezihlanganiswayo kufanele zibonise:

• I-Biodegradability okungenani engu-90%, iguqulela ku-CO₂phakathi nezinyanga eziyisithupha.
• Ukuhlakazeka, okuholela ensaleni engaphansi kuka-10%.
• Ukuhambisana nenqubo yokwenza umquba.
• Amazinga aphansi ezinsimbi ezisindayo, ngaphandle kokuphazamisa ikhwalithi yomquba.

Isiphetho

Ukubola kwezinto eziphilayo kukodwa akuqinisekisi ukuvundisa;izinto zokwakha kumele futhi zihlakazeke phakathi nomjikelezo owodwa wokwenza umquba.Ngokuphambene, izinto ezihlukaniswa zibe izingcezu ezincane ezingaboli ngomjikelezo owodwa azibhekwa njengezivundisiwe.I-EN 13432 imele izinga lobuchwepheshe elivunyelanisiwe, elihambisana ne-European Directive 94/62/EC yokupakisha nokupakisha imfucuza.
