Canada - Tops in Trash

Thanks to Kim at Bacon and Eh's for pointing me to this little nugget of information.

Canadians produce more garbage per person than any other nation in the world.

Because it's sent to Michigan, the issue of Canadian garbage has been controversial for decades and, as it turns out, a big part of the problem is that Canadians are garbage overproducers.

I've been trying to think of a slang term for garbage overproducer, but not much comes immediately to mind. Trashier? Trashiest? Maybe. Anyone else got an idea?
