Great! Let's dump the metal into the wider environment, shall we? This
is a misuse of resources and an attempt to provide a "fix it" approach
instead of tackling the problem at source.

The solution is to stop polluters from putting pollution into the
environment. In the case of polluted land, the polluter must pay to
remove the contaminants from the soil, not allow it to be "diffused"
into the atmosphere!
