Uyini umehluko phakathi kwe-“compostable” kanye “ne-biodegradable”?

Ukuvela kokupakishwa kwemikhiqizo eco-friendly kwaqhutshwa isidingo sokudala isisombululo esisha sokupakisha esingakhiqizi imfucuza kanye nobuthi obufanayo nezinto zokwenziwa ezaziwayo, njengamapulasitiki avamile.I-Compostable ne-biodegradable amagama avame ukusetshenziswa esihlokweni sokusimama ezintweni zokupakisha, kodwa yini umehluko?Uyini umehluko lapho uchaza izakhiwo zokupakisha njengokuthi “ezivundisiwe” noma “ezibolayo”?

1. Kuyini “okuvundisayo”?

Uma impahla ivundisiwe, kusho ukuthi ngaphansi kwezimo zokuvundisa (izinga lokushisa, umswakama, umoya-mpilo kanye nokuba khona kwama-microorganisms) izoqhekeka ibe yi-CO2, amanzi kanye nomquba ocebile ngezakhi phakathi nesikhathi esithile.

2.Kuyini "i-biodegradable"?

Igama elithi “biodegradable” limele inqubo, kodwa asikho isiqiniseko mayelana nezimo noma isikhathi lapho umkhiqizo uzobhidlika khona futhi wehlise izinga.Inkinga ngegama elithi “biodegradable” ukuthi yitemu elingacacile elingenaso isikhathi esicacile noma izimo.Ngenxa yalokhu, izinto eziningi ezingeke “zikwazi ukubola” uma kwenziwa zingabhalwa ngokuthi “zinokubola”.Uma sikhuluma ngobuchwepheshe, zonke izinhlanganisela zemvelo ezenzeka ngokwemvelo zingashintshwa ngaphansi kwezimo ezifanele futhi zizobhidlika ngokuhamba kwesikhathi, kodwa kungathatha amakhulu noma izinkulungwane zeminyaka.

3. Kungani i-“compostable” ingcono kune-“biodegradable”?

Uma isikhwama sakho sibhalwe ukuthi “compostable,” ungaqiniseka ukuthi sizobola ngaphansi kwezimo zokwenza umquba phakathi kwezinsuku eziyi-180.Lokhu kufana nendlela ukudla nemfucuza yasengadini okuchithwa ngayo amagciwane, kushiye insalela engenabo ubuthi.

4. Kungani kubalulekile ukuvundisa?

Imfucumfucu yokupakishwa kwepulasitiki ivamise ukungcoliswa udoti wokudla kangangokuthi ayikwazi ukugaywa kabusha futhi igcine ishisiwe noma ikulahliwe.Yingakho kwaqaliswa ukupakishwa kwe-compostable.Akugcini nje ngokugwema ukuchithwa komhlaba kanye nokushiswa, kodwa umquba ovelayo ubuyisela izinto eziphilayo emhlabathini.Uma udoti wokupakisha ungahlanganiswa nezinhlelo zikadoti wemvelo futhi usetshenziswe njengomquba esizukulwaneni esilandelayo sezitshalo (umhlabathi onomsoco), khona-ke imfucumfucu iyakwazi ukuphinda isetshenziswe futhi isetshenziswe emakethe, hhayi nje "njengodoti" kodwa futhi njengento ebaluleke kakhulu kwezomnotho.

Uma unentshisekelo ku-tableware yethu ye-compostable, sicela usithinte ukuze uthole ulwazi olwengeziwe.

I-Zhongxin inikezela ngemikhiqizo ehlukahlukene yokudala edalwe ngezinto ezivuselelekayo nezigaywe kabusha, njengezitsha, izinkomishi, izivalo, amapuleti neziqukathi.
