Okungavundiswa yi-compost vs Okubolayo: Yikuphi Ukupakishwa Okunobungani Nemvelo Okungcono Ngempela?

Amagama anjengelithi "biobolitable" nelithi "compostable" avame ukusetshenziswa sengathi asho into efanayo, kodwa aholela emiphumeleni ehlukene kakhulu. Eminye imikhiqizo ishiya ama-microplastic, kanti eminye iphela kuphela ngaphansi kwezimo ezithile zokucompost abasebenzisi abaningi abangazifinyeleli. Lokhu kudideka kuthinta izinhlobo, abathengi, ngishoAbahlinzeki Bokupakisha Abanobungani Nemvelo, okwenza kube nzima ukukhetha izinto ezinengqondo ngempela.

Ukuqondaokubolayoakuseyona into encane - ithinta ngqo izinhlelo zokulahla imfucuza, imigomo yokuzinza, kanye nemiphumela yangempela yezemvelo.

1. Kusho ukuthini ngempela ukuthi “Okubolayo”?

1.1 Indlela izinto ezibola ngayo

Abantu abaningi bayabuza: kusho ukuthini ngempela ukuthi into ebolayo?
Izinto ezibolayo ziyinto engahlukaniswa yizinto ezincane ezifana namagciwane kanye nesikhunta. Lezi zinto eziphilayo zidla izinto bese zishintsha kancane kancane zibe izinto ezincane.

Izinto ezivame ukubola zifaka:

• Izinsalela zokudla
• Iphepha
• Ezinye izinto ezisekelwe ezitshalweni
• Amapulasitiki athile abhalwe ukuthi angabola

Kodwa-ke, igama elithi “okubolayo” lilandisa ingxenye nje yendaba. Alichazi ukuthi izinto ziwohloka ngokushesha kangakanani, yiziphi izimo ezidingekayo, noma ukuthi izinsalela eziyingozi zihlala zikhona yini.

1.2 Kungani “ukungabi namkhawulo wesikhathi” kuyinkinga enkulu

Inkinga enkulu ngegama elithi “okubolayo” ukuthi akukho mkhawulo wesikhathi osemthethweni noma ojwayelekile wokuthi ukuqhekeka kufanele kuthathe isikhathi esingakanani. Eminye imikhiqizo ebhalwe ukuthi iyabolayo ingase inyamalale ngokuphelele ezinyangeni ezimbalwa, kanti eminye ingathatha iminyaka emi-5, 10, 50, noma ngisho namakhulu eminyaka. Abakhiqizi bangasebenzisa leli gama kalula ngoba akukho zindinganiso zomhlaba wonke eziphoqelela isikhathi esithile. Lokhu kusho ukuthi isikhwama sepulasitiki esibhalwe ukuthi “okubolayo” sisengahlala cishe singashintshi endaweni yokulahla udoti emashumini eminyaka kamuva. Ngaphandle kwesikhathi esibekiwe esicacile, ilebula iba igama lokumaketha kunokuba isithembiso esithembekile. Yingakho ochwepheshe abaningi bezemvelo bethi leli gama livame ukudukisa abathengi abavamile.

1.3 Ingozi efihliwe yama-microplastic

Uma izinto ezibolayo ziwohloka kancane noma zingaphelele, zivame ukuphenduka zibe yizingcezu ezincane zepulasitiki ezibizwa ngokuthi ama-microplastics esikhundleni sokunyamalala ngokuphelele. Lezi zingcezu zivame ukuba zincane kuno-5mm futhi zingahlala enhlabathini, emifuleni, emachibini, nasezilwandle isikhathi eside kakhulu. Izilwane zicabanga ukuthi ziwukudla, izinyoni nezinhlanzi ziyazidla, futhi izingcezu zingakhuphuka ochungechungeni lokudla ukuze zifinyelele kubantu. Ama-microplastics atholakale emanzini okuphuza, usawoti, ngisho nasegazini nasemaphashini abantu. Ngenxa yale ngozi, ososayensi abaningi manje baphikisana ngokuthi ukubiza into ngokuthi “ibolayo” akuyenzi ngokuzenzakalelayo iphephe noma ibe nobungane nemvelo ngempela.

2. Yini Eyenza “I-Compostable” Ihluke — Futhi Iqine Kakhulu

2.1 Kumelwe kube umquba wangempela, hhayi izingcezu ezincane nje

Ukupakishwa komquba kufanele kwenze okungaphezu nje kokuqhekeka. Kumelwe kubole ngokuphelele kube umquba ocebile ngezakhamzimba - izinto ezimnyama, eziqhekekile njengenhlabathi ezithandwa ngabalimi futhi ezisiza izitshalo zikhule ziqine. Ekupheleni kwenqubo, akufanele kube khona izingcezu ezibonakalayo ezisele kanye namakhemikhali ayingozi asele kumquba. Lo mkhiqizo wokugcina uphephile ukuwusebenzisa emapulazini, ezingadini, nasemahlathini ngaphandle kokubangela ukungcola. Umgomo awukona nje ukunyamalala, kodwa empeleni ukudala okuthile okuwusizo nokuhle emvelweni. Lowo umehluko oyinhloko owenza umquba ube yisigaba esiqinile kakhulu.

2.2 Izidingo ezine eziyinhloko zesitifiketi

Ukuze umkhiqizo ubizwe ngokusemthethweni ngokuthi ungavundiswa, kufanele uphumelele izivivinyo ezine zesayensi eziyinhloko ezibekwe yizindinganiso zomhlaba wonke.

• Okokuqala, okungenani u-90% wezinto kumele zibole zibe yizinto zemvelo njenge-carbon dioxide, amanzi, kanye ne-biomass ngesikhathi esibekiwe.
• Okwesibili, kumele ihlakazeke ngokomzimba — okusho ukuthi azikho izingcezu ezinkulu ezisele ngemva kokwenza umquba.
• Okwesithathu, umquba ophumayo kumele uphumelele ukuhlolwa kobuthi bemvelo okubonisa ukuthi awuzilimazi izitshalo noma impilo yenhlabathi.
• Okwesine, yonke inqubo ngokuvamile kumele iphele zingakapheli izinsuku ezingu-180 ezimweni zokwenziwa komquba ezimbonini.

Le mithetho eqinile iqinisekisa ukuthi izimangalo zingokoqobo futhi ziyalinganiswa.

2.3 Izitifiketi eziqashelwa kakhulu emhlabeni jikelele

Izitifiketi ezithembeke kakhulu zifaka phakathi i-BPI (i-Biodegradable Products Institute) eNyakatho Melika, esebenzisa indinganiso ye-ASTM D6400 yokwenza umquba wezimboni. EYurophu, indinganiso ye-EN 13432 ivamile, ivame ukuboniswa nelogo ethi “Seedling” evela ku-TÜV Austria. Ungase futhi ubone “OK compost INDUSTRIAL” yezindawo zezentengiselwano noma “OK compost HOME” entsha yokwenza umquba egcekeni. Lawa malebula asho ukuthi amalabhu azimele ahlole umkhiqizo izikhathi eziningi. Uma ubona enye yalezi zimpawu, ungaqiniseka ukuthi into izosebenza njengoba ithembisile ngaphansi kwezimo ezifanele.

3. Ukwenziwa komquba kwezimboni vs. Ekhaya: Uyini Umehluko Wangempela?
