The smell is pretty bad though - need to open the window.

The dye used is pthalocyanine some of it will be released as cyanide by
burning. Not advised in a confined space such as a kitchen.

I thought I'd heard something like that, hence my question. However,
I guess this isn't a problem with the quick blast in the microwave?

I wouldn't think the microwave would be a problem. I use a cross-cutting
shredder for cds, it's less of problem than any other disposal method.
However I think the shredder cost around £700 so it's not a home use
option.

In the past the technique used was a propane torch and a firebrick
hearth to melt down CDs and Hard Disk platters.
