Someone else suggested going to a composting site, but freezing the waste wasn’t mentioned. This seems like a step in the right direction, but still worried about it thawing during the trip and the wastewater leaking through the bag, causing a mess and disturbing other bus passengers with the smell.
Never had it happen with waste bags, but I’ve seen a few times where people (my family included growing up) would bring in bagged bottles and cans to return for bottle deposit, and the bus drivers were never pleased when the bags leaked.
With worms though? Wouldn’t they see that as a potential pest attractor?
