If you decide to dispose some/all, DO NOT BURN. It will produce extremely toxic smoke/fumes. If you have access to a paper shredder, use it since most shredders are designed to handle cd/dvd/blu ray media and then dispose in garbage. If you don't have access to a shredder, you can use string pair of sharp scissors. It will just take longer to do the job.
