The evidence regarding sales of bin liners is mixed:
> The study found California communities with bag policies saw sales of 4-gallon trash bags increase by 55% to 75%, and sales of 8-gallon trash bags increase 87% to 110%. These results echo earlier studies that also showed increases in sales of smaller plastic trash bags.
But while sales of small garbage bags jumped after policies were implemented, sales of larger 13-gallon trash bags -- the size often found in kitchen trash cans -- remained relatively unchanged. [1]
Personally I can say I switched to just not lining the bin after the plastic bag ban. I have a separate compost bin for food scraps so the main bin mostly doesn't get too dirty, and if it does get some liquid or whatever on it, a quick rinse with the hose fixes that.
We use a paper bag (from grocery deliveries) as our general household waste bin under the sink. Also under the sink are a compost bin and then a recycling tub. The compost and recycling tubs fill up far faster than the general waste bag.
