MPP... our move gave us access to city compost and a recycling system that still accepts a lot of plastics. So now we have very little trash. This means, even with our relatively small can, our trash starts to stink long before it's full (dog poo....). I hate wasting the bags by throwing them away partially filled, but I can't handle the smell!
(For the "solvers", no, my city doesn't do plastic shopping bags, and I use my own bags anyway, so I can't just use those. We don't eat cereal or bread, so can't use those bags either. Current plan is for the time being to use the plastic produce bags as a bag within a bag for the dog poo bags, but even those will be gone soon when we get our reusable produce bags bought!)
