Ezweni lanamuhla eliqaphela imvelo, amagama anjengokuthi “i-biodegradable” nelithi “compostable” avame ukusetshenziswa ngokushintshana, kodwa ukuqonda umehluko kubalulekile ekwenzeni ukukhetha unolwazi. Nakuba zombili izinto ezisetshenziswayo kuthiwa zinobungani bemvelo, zibhidlika ngezindlela ezihluke kakhulu ngaphansi kwezimo ezithile. Lo mehluko ungaba nomthelela omkhulu ezinzuzweni zabo zezemvelo, kusukela ekunciphiseni imfucumfucu yokucekela phansi imfucumfucu kuya ekucebiseni umhlabathi.
Ngakho-ke, yini ngempela ehlukanisa izinto ezibolayo nezivundisekayo? Ake sihlole ama-nuances ngemuva kwala malebula aluhlaza nokuthi kungani ebalulekile ngeplanethi yethu.
• I-biodegradable
Izinto ezibolayo eziphilayo zibhekisela ezintweni ezingase zigaywe zibe izinto zemvelo (amanzi, i-methane) enhlabathini noma emanzini ngama-microorganisms kusetshenziswa ubuchwepheshe be-biodecomposition. Lokhu yingokwemveloinqubo eyenzekayo engadingi ukungenelela kwangaphandle.
• Ivundisiwe
Izinto ezivundisayo umanyolo ohlukaniswa ngokwemvelo ngokuhamba kwesikhathi ngama-microorganisms (okuhlanganisa isikhunta, amagciwane, amaprotheni ezilwane nezinye izinto eziphilayo) abe yi-carbon dioxide, amanzi kanye ne-humus, okunomsoco futhi okusetshenziselwa ukulima.
Okwamanje kunezinhlobo ezimbili zezinto zokwakha umquba -I-Industrial Composting & Home Composting.
