Shredding from A to Z

By DeAnne Toto dtoto@SDBmagazine.com 3/4/2004 2:06:59 PM

Manufacturers offer a variety of shredding options to information destruction professionals.

Shredders are essential to the information destruction industry, helping to ensure the privacy and security of sensitive information, dated electronics or defective and obsolete products at the time of their disposal.

Manufacturers have seen to it that secure destruction professionals have a variety of shredding equipment to choose from to meet size reduction needs and to accommodate the range of materials that require secure shredding. Today’s shredding equipment includes large stationary systems that can handle diverse streams of material, mobile document destruction trucks, and small desktop or departmental shredders for confidential papers.

For information destruction professionsals, shredders ensure the safe destruction of documents, electronic storage media and even hard drives and computer equipment. In some cases, the machines play a role in the recycling process that follows, such as when they grind computer equipment into pieces for later separation by commodity type.

On the following pages, we’ve rounded up a sampling of the shredding equipment currently available to the information destruction industry.

• Offers greater document security than conventional strip-cut shredders

• Provides cost advantages compared to grinding systems

• Throughput of one to 25 tons per hour, depending on material

• Easily destroys boxes of CDs, video tapes, reels, etc.

• Low-dust, low-noise operation

• Jam-free, auto-feed systems

• Existing shredding systems can be integrated within the design in most
cases, providing a cost-effective solution
