Effective destruction of waste products so as to make the cost
of exploiting those waste products commensurate with the value of keeping
those waste products from being exploited. Examples include:
shredding of waste paper,
destruction of electromagnetic media,
removal and destruction of labels and other related information, and
the introduction of noise to reduce the signal-to-noise ratio.
Complexity: In most cases, well known and reasonably inexpensive techniques
are available for destruction of waste. Cost and complexity goes up for
destruction of some materials in a very short time frame with very high
assurance, but this is rarely necessary.
