I-biodegradable isho ukuthini?Ihluke kanjani ekuvundiseni?

Amagama athi “biodegradable” nelithi “compostable” akhona yonke indawo, kodwa avame ukusetshenziswa ngokushintshana, ngokungalungile, noma ngokudukisayo – okwengeza ungqimba lokungaqiniseki kunoma ubani ozama ukuthenga ngendlela eqhubekayo.

Ukuze wenze ukukhetha okufanele iplanethi, kubalulekile ukuqonda ukuthi i-biodegradable ne-compostable isho ukuthini, ukuthi ayisho ukuthini, nokuthi ihluke kanjani:

Inqubo efanayo, isivinini esihlukile sokuhlukaniswa.

I-Biodegradable

Imikhiqizo ebolayo iyakwazi ukubola amagciwane, isikhunta noma ulwelwe futhi ekugcineni izonyamalala endaweni ezungezile futhi ingashiyi amakhemikhali ayingozi ngemuva.Isikhathi asichazwanga ngempela, kodwa akuzona izinkulungwane zeminyaka (okuyimpilo yamapulasitiki ahlukahlukene).
Igama elithi biodegradable lisho noma iyiphi into engahlukaniswa amagciwane (afana namagciwane nesikhunta) futhi ahlanganiswe endaweni yemvelo.Ukuwohloka kwezinto eziphilayo kuyinqubo eyenzeka ngokwemvelo;lapho into yehla, ukwakheka kwayo kwasekuqaleni kwehla ibe izingxenye ezilula njenge-biomass, i-carbon dioxide, amanzi.Le nqubo ingenzeka nge-oxygen noma ngaphandle kwayo, kodwa kuthatha isikhathi esincane lapho umoya-mpilo ukhona- njengalapho inqwaba yamaqabunga egcekeni lakho iphuka phakathi nenkathi yonyaka.

I-Compostable

Imikhiqizo ekwazi ukubola ibe inothe ngezakhi, izinto zemvelo ngaphansi kwezimo ezilawulwayo endaweni yokwenza umquba wokuhweba.Lokhu kufezwa ngokuchayeka okulawulwayo kuma-microorganisms, umswakama kanye nezinga lokushisa.Ngeke kudale amapulasitiki amancane ayingozi uma ebhidlizwa futhi anomkhawulo wesikhathi othize kakhulu futhi oqinisekisiwe: aphuka ngaphansi kwamasonto ayi-12 ezimeni zokwenza umquba, ngakho-ke alungele ukwenziwa komquba wezimboni.

Igama elithi compostable lisho umkhiqizo noma izinto ezingase ziwohloke ngaphansi kwezimo ezithile eziqhutshwa umuntu.Ngokungafani ne-biodegradation, okuyinqubo yemvelo ngokuphelele, ukwenza umquba kudinga ukungenelela komuntu
Ngesikhathi sokwenza umquba, ama-microorganisms aphula izinto eziphilayo ngosizo lwabantu, abanikela ngamanzi, umoya-mpilo, nezinto eziphilayo ezidingekayo ukuze izimo zibe ngcono.Inqubo yokwenza umquba ngokuvamile ithatha phakathi kwezinyanga ezimbalwa kanye nonyaka owodwa kuya kwemithathu.Isikhathi sithintwa izinto eziguquguqukayo ezifana ne-oxygen, amanzi, ukukhanya, kanye nohlobo lwendawo yokwenza umquba.
