Two sources from Japan address the issue of garbage disposal in a camper. One author lived in a camper for two years, another couple has been traveling through Europe for 2.5 years. The main difficulty is the lack of places to dispose of waste during stops. Sorting rules vary by country, and in some regions finding a disposal site is challenging.
Given the limited space inside a camper, waste must be stored inside, requiring special measures to prevent odors. Compact containers and a waste disposal schedule are suggested.
