I don't know if this counts as a hack but the most recent one revolved around a trash company that overloaded itself and could not pick up trash for a week. I temporarily stopped using large trash-bags and instead put trash daily into disposable shopping bags. It turns out I can fit about 60% more waste in their garbage container using disposable shopping bags than I can using the 30-39 gallon bags. This might be useful for people that rent two or more of the garbage containers. To list all my hacks would need a blog.
