You can put an enzyme cleaner in the bottom bin to help minimize odors--Biokleen has a laundry detergent with enzymes, which is more cost-effective and more environmentally friendly than buying jugs of nature's miracle (which costs $30 per gallon and is ~95% water...just buy the enzymes and add water yourself). And pellet fuel is basically the same thing as pine litter but only costs $10 for a 40 lb bag. Pine litter/pellet fuel is a lot less messy than clay, very hard for a cat to kick out of their litterbox. It does absorb odors over time; I usually dump the spent litter/sawdust in the bottom bin once a week, and dump the whole box every month or two when it starts to smell. A 40 lb bag probably lasts about six months to one year per cat. If you can convince your cat to make the switch...if your cat is still young, there's hope they could adjust to the change.
Also, don't know if this is the most environmentally friendly thing to do, but I flush cat poo down the toilet so no need for bags. I try to dust my yard with the spent pellet fuel/sawdust, it is mostly just carbon/wood that will biodegrade in the wet and humid climate of south Louisiana.
