More in physical privacy space than the usual post. Whenever I get mail, I shred it before disposal. Whenever I get a package, I black out the label.
But my method for blacking out the labels is basically turning on the gas range and holding the label over it until it turns black. It's not even that good of a method, because I can still see a black-on-black print.
So, I'm wondering if anyone has any better ideas for this sort of thing.
With either burning or pulping, you can simply flush the remains down the toilet.
If burning, you should use an accelerant and make sure they are fully incinerated, and then stir the ashes to break up any large pieces of charred paper. Stacks of paper are notoriously hard to burn on their own, but if left in an existing fire long enough they will burn to ash just like wood.
For pulping, an alternative I just saw on another site would be to mix the slurry in a blender to chop the pieces. That would certainly be faster than what I said previously.
