Recycling vs. Destruction Of Tape Media
     Introduction
  1. Tape media continues to be the most widely used technology for storing and protecting digital data.
  2. In managing tape media, organizations are challenged with the task of disposing of tape properly when it reaches end of life. Tape disposal is not a trivial matter for two major reasons:
    • First, tape contains valuable company information and this information must be either erased or destroyed so that it does not fall into the
    • wrong hands.
    • Second, tape media is not made of biodegradable material and it is highly desirable to eliminate it from the solid waste stream.
  3. There is increasing legal and regulatory pressure to store electronic information longer. Much of the data that tape contains is governed by federal and state regulations such as Health Insurance Portability and Accountability Act (HIPPA), Gramm-Leach-Bliley Act, Sarbanes-Oxley Act and California SB 1386. Federal and state regulations mandate that the sensitive information contained on tape be protected. This makes the disposal of tape media a serious concern to the public and private sectors. Depending on the violation, improper disposal of tape media could result in fines or other serious penalties.
  4. Environmental Concerns One difficulty with tape media disposal is that tape media is not a biodegradable product making it a challenge to dispose of responsibly. The plastic and metal components that make up the tape are destined to become solid waste and sit in land fills for hundreds of years. The best land fills are not completely tight throughout their lifetimes and a certain amount of chemical and metal leaching will occur. There is also a risk that tape media might end up in an illegal land fill or be incinerated, releasing toxic material into the atmosphere. Low cost bidders for media disposal, for example, may be working through brokers to send media to developing countries or to illegal waste dumps in the U.S. to reduce disposal costs, so be careful! Your tapes, and the data they contain, may cross borders and change hands many times before being destroyed.
  5. Media Disposal Methods
    Two principle methods exist for the disposal of tape media.
    • One method is to physically destroy the tape media and the second is to fully eradicate the data on the tape.
    • The destruction process is simply to physically cut and pulverize the media. Specialized commercial equipment is designed for this purpose. Tape is fed into these machines and ground into small pieces. The end result is solid waste that must be disposed of in an authorized land fill.
    • Incineration is another method of tape destruction. All the material is completely incinerated and there is no solid waste to dispose of. The challenge of incineration is the byproduct of burning a tape is thick black smoke and the release of toxic gasses. Whatever method is performed to destroy tape media, the media needs to be disposed off in an environmentally acceptable manner. Always work only with a reputable disposal service provider, who uses only approved disposal methods and can provide you with a certificate guaranteeing that your tape has been properly disposed off.
    • The second method of disposal involves erasing the existing data from the tape. Proper erasure removes the risk that the pre-existing data on the tape falls into the wrong hands. Erasing is the process of applying a high intensity magnetic field to the media to re-arrange the magnetic particles & effectively erasing all existing data.
      Magnetic degaussing will leave the media with no preference to orientation, rendering previous data unrecoverable. The 3480, 3490, DLT and SDLT tapes are examples of tapes that can be erased many times without any reduction in their useful life.
      In order to properly degauss magnetic media, a magnetic force (gauss) of 2 to 3 times greater than the media to be degaussed must be created. Home VHS tapes have a magnetic strength (650 oersteds) as compared to computer cartridges (1800 oersteds). Because of this difference, "home" degaussing equipment designed for VHS tapes will not do a complete job of erasing computer cartridges. Only professional grade degaussing equipment, correctly calibrated and operated will do a proper job of erasing computer cartridges.
      Not all popular computer cartridges can be degaussed. Professional guidelines for proper tape degaussing are available from the Dept. of Defense 5220.22- M and National Security Agency and computer manufacturers such as IBM. These guidelines stipulate the proper methods to use for certain media types.
    • Note: The entire data eradication process can often be completed on-site to ensure total data security.
  6. The Benefits of Recycling Tape Media.
    • The most environmentally sound decision is to recycle tape.
    • Used tape media that is not physically damaged and has not exceeded its end of useful-life can be sold to reputable disposal service providers who will securely remove all existing data from the tape and certify secure data eradication by providing a certificate of data destruction. The data eradication process requires specialized equipment and trained personnel and it should only be managed by an experienced disposal service provider. Your organization will benefit from a professional service provider who will manage the entire disposal process from pick-up at your site to delivery of all proper certificates of disposal. You are assured that your data does not fall into the wrong hands and that the environment is not impacted.
    • The recycling of tape media is an environmentally superior alternative to disposal. Recycling is also a cost-effective solution. The cost to have tape removed and physically destroyed can be as much as $3 to $8 per tape. This fee covers the cost to securely transport tape to the service facility and perform its destruction and disposal. For recycling, the cost for tape disposal is very different because the end product can be reused and has value. The end product of tape destruction is solid waste and has no value. Disposal service providers who recycle can reduce the disposal cost by selling the end product for certified reuse. They can pass these savings to you, making recycling far more cost effective than physical destruction.
    • Managing the Security Risk
      Data security is a major issue for tape - just ask Iron Mountain who lost 40 backup tapes in May 2005 of one of its clients. The data on these tapes contained the social security numbers for 600,000 employees. The loss of this data was a very serious matter. The major risk that tape disposal presents is the miss-handling of confidential information. This risk exists for both tape destruction and tape recycling. Take for example the chance that an un-reputable disposal service provider fails to destroy the tapes; but rather sells them for reuse or looses them in transit due to poor controls. This is clearly a risk that must be mediated up front when considering destruction. Disposal service providers who legitimately recycle tapes must use the proper degaussing equipment and must follow strict guidelines to ensure that all data is 100% erased. In all situations when dealing with disposal service providers, their reputation is the most important factor to consider.
      New security technologies are available that can reduce the risk of losing confidential data. Encryption technology can be applied to the tape header or to the entire tape to ensure that the data on the tape can never be read by an unauthorized person. Encryption uses a special encryption key that is only known to the authorized person who encrypted the data. When more and more data is encrypted on tape, the risk of losing confidential data will be eliminated clearing the way for more tape recycling and its benefits to the environment and bottom line of the companies making this choice.

Conclusion
Your company relies on tape to protect all of its digital assets and you must manage tape securely throughout its entire life-cycle including end-of-life. At end-of-life you have important decisions to make regarding the secure disposal of media. Your decision to have tape destroyed may appear to offer the least risk; but it is costly and negatively impacts the environment. The decision to recycle media offers a much lower cost and greatly reduces the impact on the environment. Tape recycling should only be handled by a trusted disposal service provider who can guarantee secure handling and the 100% erasure of all confidential data and provide certificates of data destruction for all tapes processed. By working to ensure your data is disposed off by a reputable disposal service provider, you can manage your tape media end-of-life in a responsible manner that balances company security, environment concerns and cost.
