Biodegradable futhi compostable

Ukuchazwa kanye ukusetshenziswa kabi

I-biodegradable futhi compostable ivame ukusetshenziswa ngokushintshana ukuchaza ukwephulwa kwezinto eziphilayo ezimeni ezithile. Kodwa-ke, ukusetshenziswa kabi 'kwe-biodegradable "ekuthengiseni kuholele ekudidekeni phakathi kwabathengi. Ukubhekana nalokhu, i-Biobag isebenzisa kakhulu igama elithi "compostable" ngemikhiqizo yethu eqinisekisiwe.

Biodegradeability

I-biodegradeability ibhekisa emandleni ezibonakalayo zokonakalisa kwemvelo, ukukhiqiza co₂, H₂O, i-methane, i-biomass, nosawoti wamaminerali. Ama-microorganisms, adliwa ngokuyinhloko yimfucuza ye-organic, shayela le nqubo. Kodwa-ke, igama elithi alinakho ukucaciswa, njengoba zonke izinto zokwakha ekugcineni i-biodegrade, egcizelela isidingo sokucacisa indawo okuhlosiwe ye-biodergradadation.

Ukuthandakayo

Ukuqamba kufaka phakathi ukugaya ama-microbial ukwehlisa imfucuza ye-organic kumquba, kuzuzisa ukuthuthukiswa kwenhlabathi kanye nokuvundiswa. Ukushisa okuphelele, amazinga wamanzi, namazinga we-oksijini kuyadingeka kule nqubo. Ezinhlangeni zokungcola kwe-organic, ama-virus ayiminyene adla izinto zokwakha, aziguqula zibe ngumquba. Ukuqothulwa okugcwele kudinga ukubambelela ezindinganisweni eziqinile ezinjenge-European Norny En 13432 nas standard astm d6400, kuqinisekiswe ukubola okuphelele ngaphandle kwezinsalela eziyingozi.

Amazinga aphesheya

Ngaphandle kwe-Europe evamile e-En 13432, amazwe ahlukahlukene anezindlela zawo, kufaka phakathi i-ASTM D6400 ne-Australia Norm AS4736. Lawa mazinga asebenza njengamabhentshini abakhiqizi, imizimba yokulawula, izikhungo zokuhlanganisa, ama-ejensi ezitifiketi, kanye nabathengi.

Izindlela zokusetshenziswa kwezinto ezikhokhwayo

Ngokusho kwe-European Standard en 13432, izinto ezikhohlisayo kufanele zikhombise:

• I-Biodegradeabilibility okungenani 90%, iguqukela ibe yi-CO₂kungakapheli izinyanga eziyisithupha.
• Ukuhlukaniswa, okuholela ekuhlekeni okungaphansi kwe-10%.
• Ukuhambisana kwenqubo yomquba.
• Amazinga aphansi wezinsimbi ezisindayo, ngaphandle kokuyekethisa umquba.

Ukugcina

I-biodegradeabilibility iyodwa ayiqinisekisi ukuqubuka; Izinto zokwakha kumele futhi zihlukaniswe ngaphakathi komjikelezo owodwa womquba. Ngakolunye uhlangothi, izinto ezingaphansi kwezingcezu ezingezona ze-micro-izingcezu ezingezinhle ngaphezulu komjikelezo owodwa azithathwa njengezinganekwane. I-EN 13432 imele izinga elihlanganisiwe lobuchwepheshe elihlanganisiwe, ihambisana ne-Europe Eliqondisayo 94/62 / EC ekupakisheni nasekupakiseni imfucuza.
