Ubuchwepheshe bokuvutshelwa komquba
Thumela i-imeyili kithi
Okwedlule: Izakhi ezibalulekile zokuvuthwa komquba Olandelayo: Thuthukisa ukuvutshelwa nokuvuthwa ngokusebenzisa i-flipper
Ukuvutshelwa komanyolo wemvelo kuhlukaniswe izigaba ezintathu
Isigaba sokuqala yisigaba se-exothermic, lapho kukhiqizwa ukushisa okuningi.
Isigaba sesibili singena esiteji sokushisa okuphezulu, futhi njengoba izinga lokushisa likhuphuka, ama-microorganisms athanda ukushisa asebenza.
Okwesithathu ukuqala isigaba sokupholisa, ngalesi sikhathi i-organic matter isuke isibolile.
