Can unused kitty litter decrease unpleasant compost bin odors?
By Mary H.
Cat litter isn't compostable unless made specifically to do so.
But the important thing is that your compost bin shouldn't smell if it's working properly. Are you using the right mix of materials (brown, green, etc, but nothing meat or dairy) and are you turning it regularly?
Even if one of those 'no need to turn' bins (HA!), all compost bins should be turned regularly to encourage decomposition without odour, more frequently if weather is humid (hot or cold, doesn't matter). I turn mine once a week.
If a compost bin is being kept properly, there should be no unpleasant odor, just an earthy smell - after all, you're making enriched dirt. What type of kitty litter are you asking about: clay, ground corn cob, ground walnut shells, shredded newspaper, etc.
