I have found a cheap shredder very reliable, as long as I take the trouble to remove staples and not to shred more than two pieces of paper at a time. I bundle the shreds into a plastic bag and put them in with the ordinary household rubbish.
I do the same with expired plastic cards (bank cards etc) after cutting them through diagonally with the kitchen scissors, but I do take care to cut through our social security numbers and dates of birth and throw the two halves out on separate bin days, so no-one can reconstruct these details, or a bank account number either.
