Dear IT Industry Colleague,
I’ve just moved house. In the process I realised that I had hundreds of old datas CD’s. Some of them with old backups, many of them used to copy copies of other CD’s some DVD’s with dumps of system folders and so on a so forth.
I figured I’d just dump them in the recycling, which gets collected bi-weekly. On checking though, not only are these not recyclable, but they are actually pretty hard to completely destroy. They also contain a large amount of toxic chemicals, and unless they are sent to a specialty recycling center, most end up in incinerators or landfill, neither is a good thing.
There is a good article here on the general problems with the creation and disposal of CD/DVD’s, from 2013. It says, among other things:
The discs are made of layers of different mixed materials, including a combination of various mined metals and petroleum–derived plastics, lacquers and dyes, which, when disposed of, can pollute groundwater and bring on a myriad of health problems. Most jewel cases are made of polyvinyl chloride (PVC), which has been thought to produce a higher-than-normal cancer rate within workers and those who live in the area where it is manufactured. They also release harmful chemicals when incinerated.
Having realized the problems, what did I do? First, when disposing old data CD’s and DVD’s you must understand there is an obvious potential security exposure. In principle, any data can be read from the CD. In practice, it may not be that simple if the data is formatted using specific backup programs, encrypted etc. But you do have to consider this before discarding them.
I came up with a couple of easy ways to make recovering data hard. One involved scratching the recording sides (remember, some are dual sided). The scratches can be removed but it’s a time consuming process and not something done by someone who casually comes across your CD.
The second process used a nail in a set of grips, I heated the nail and simply pushed a couple of holes through each CD/DVD. Again, some data could still be read by the determined, but very unlikely.
Once I was done marking all the media, I threw them in an old Amazon box, too them to the US Post Office, mailed them as “media mail” to the CD Recycling Center of America. The CD Recycling Center provides “certified destruction” of your CD’s.
Our industry uses vast amounts of natural resources, it consumes rare minerals at an alarming rate, often mined in difficult, dangerous, and sometimes illegal conditions. Individually this is hard for us to do anything about. Please though, don’t throw old data CDs, DVD’s or any others in the garbage/trash/refuse and especially the recycling.
Yes, it takes a few minutes of your time; yes, it will cost you to box, tape, address and actually post the package back for destruction. Over the years IT has made me a lot of money, it is the least I could do. Please join me. Thank you.
