We were in another area that didn’t allow bags, so we use a litter geenie XL. They sell compostable liners on Amazon. Target also sells the inserts in store brand. Our dogs have been using compostable poop bags for a while. I’ve also used dollar tree trash liners (for smaller cans) but we are trying to limit the amount of plastic we toss; however, those are very budget friendly as a roll of 50 is 1.25.
