Yes, cockroaches dont survive a northern winter.I fill/ballast the bottles with seawater.... and spike the cans.
Cardboard is an issue as some is 'plasticised' and can't go over.... and the rest probably takes a long time to biodegrade. But we don't have that much... mainly empty beer boxes.... anyway it can all be packed flat and retained on board. It was aboard before you took the cans out so it can stay aboard after the cans have been consumed. One thing I have never ever had is cockroach issues with cardboard... maybe thats a tropical thing?
Cardboard is mainly wood fibre ,which has been falling in the ocean for as long as trees have been around.
