Issues involving Waste Management Facility and its subclasses

[gregfowlerphd]

According to the former’s definition, a waste management facility manages waste from its inception to its final disposal. However, few instances of its subclasses--Landfill and Sewage Treatment Facility--actually do this. Instead, the waste exists prior to being transferred to such facilities.

It might be possible to resolve this issue by changing the definition to something like:

A Facility that is designed for managing waste at its final disposal and for some time prior to it.

However, I worry that even this isn’t quite right. Suppose a facility is designed for processing waste during the middle of its existence, after which it is transferred to another facility for final disposal. Given either the current definition or the revised one presented above, such a facility would not count as a waste management facility, which seems mistaken.

Perhaps, then, the correct definition is something like this?:

A Facility that is designed for managing waste for some portion of the waste’s existence.
